10 Best Conference Room Projectors with Vertical Keystone Correction of 2026

The HP MC425 by Lyncast is a compact, portable projector built for anyone who wants a simple home theater setup without juggling extra streaming boxes. Running on Android TV OS, it comes with Netflix, Prime Video, YouTube, Disney+ and Tubi baked right in, making it a great fit for casual movie nights, dorm rooms, or small apartments where a full TV setup isn't practical.

What stands out most is the auto focus and auto keystone correction, which reviewers consistently praise for making setup nearly instant. With native 1080P resolution, 4K support, and 200 ISO lumens, the image quality punches above its price point, delivering sharp detail and vibrant color that multiple users compared favorably to a mini home theater experience. The dual HiFi speakers add to the immersive feel, meaning you won't necessarily need an external soundbar for casual viewing.

Design-wise, the projector is lightweight at just 810 grams, with a 90-degree rotation feature that lets it project onto walls, ceilings, or outdoor screens without a dedicated mount. The short-throw 0.8:1 ratio is particularly useful in tighter spaces, letting you get a 100-inch image from just 1.4 meters away, which is handy for smaller rooms or camping setups.

The main limitation is brightness. At 200 ISO lumens, this projector performs best in darker rooms or at night, so it's not ideal for bright living rooms during the day. The USB-C power bank feature is a nice touch for outdoor use, but it does require a power bank rated at 65W or higher, which not everyone will already own. The remote also needs AAA batteries that aren't included, a small but easy-to-overlook detail.

Overall, this is a strong budget pick for anyone prioritizing convenience and built-in streaming over maximum brightness. Reviewers consistently rate it highly for picture clarity, ease of setup, and value, making it a solid choice for family movie nights, dorm entertainment, or outdoor screenings after dark.

The HP MC425 features a native resolution of 1920 x 1080 with support for up to 3840 x 2160 (4K) input, paired with 200 ANSI lumens brightness and a 1500:1 contrast ratio for reasonably crisp visuals in dim rooms.

Connectivity includes HDMI, USB, USB Type-C, a 3.5mm audio jack, WiFi 6 (2.4G/5G), and Bluetooth 5.4, allowing it to pair with laptops, tablets, smartphones, gaming consoles, and external speakers.

The projector operates on 55 watts of power with a 40-watt lamp rated for 50,000 hours of use, and supports a throw distance between 0.6 and 3 meters, producing images from 60 up to 130 inches diagonally.

It measures 8.2 x 4.7 x 4.7 inches and weighs 810 grams, making it easy to transport, and it ships with a remote control, HDMI cable, Type-C adapter, travel bag, and cleaning kit.

The HAPPRUN KC7 PRO is a smart outdoor projector aimed at buyers who want a big-screen experience without being locked into a dark room or a pile of extra hardware. It suits casual movie fans, backyard entertainers, and gamers who value quick setup over granular manual controls.

Its standout feature is the true 3000 ANSI lumens brightness, which lets it hold up against ambient light far better than typical budget projectors. Combined with 4K decoding, HDR10 support, and a 20,000:1 contrast ratio, the image stays sharp and colorful whether you're indoors or under the evening sky. Reviewers consistently praise how fast and accurate the auto focus and 6D auto keystone are, removing the usual trial-and-error of projector setup.

Build quality is compact and practical, with a desktop form factor that also supports ceiling mounting and tripod use. Dual 10W Dolby Audio speakers add surprisingly full sound for a projector this size, and WiFi 6 plus Bluetooth 5.2 keep streaming smooth and wireless audio pairing simple.

The main caveats are that the native resolution is 1080p rather than true 4K, and keystone correction is digital only, with no optical adjustment or angled leg support. A few users also noted the built-in smart apps come with a privacy policy worth reviewing before diving in.

Overall, the KC7 PRO delivers a lot of convenience and picture quality for the price, especially for anyone who wants an all-in-one, plug-and-play projector for both indoor and outdoor movie nights.

Native resolution is 1920 x 1080 with 4K decoding support, HDR10, a 20,000:1 contrast ratio, and 95% color gamut coverage for vivid, detailed visuals.

Brightness is rated at 3000 ANSI lumens, with image size scaling from 40 to 300 inches and a throw distance range of 5.48 to 22 feet.

Connectivity includes HDMI, USB 2.0, 3.5mm audio, Bluetooth, and WiFi 6, with remote and voice control options for easy operation.

The unit weighs 7.1 pounds and measures 11.4 x 4.5 x 10.4 inches, backed by a 24 month warranty and a rated light source life of 100,000 hours.

The Lisowod L61Pro 2.0 is a portable smart projector designed for users who want a complete home theater or outdoor cinema experience without the clutter of multiple devices. Running on the proprietary AI Movin 2.0 OS with a quad-core A55 processor, it targets movie lovers, casual gamers, and families who value convenience and picture quality in equal measure.

The projector's standout feature is its comprehensive AI system, which handles auto focus in roughly 3 seconds, keystone correction in 0.1 seconds, and even obstacle avoidance automatically. Combined with 360-degree orientation detection, you can place this projector almost anywhere and expect a properly aligned, sharp image with minimal manual adjustment. The native 1080P panel with 4K decoding, a 25000:1 contrast ratio, and 99% NTSC color coverage delivers genuinely vibrant and detailed visuals on screens up to 300 inches.

Audio performance is a clear strength here. The dual 50W Dolby-certified speakers produce room-filling sound with real bass presence, which is rare in a projector at this size and price point. Bluetooth 5.2 with bidirectional support and eARC compatibility means you can also connect external speakers or headphones with ease. WiFi 6 dual-band connectivity keeps streaming smooth and lag-free, and the pre-installed official streaming apps mean you are up and running immediately out of the box.

On the downside, a few app compatibility limitations are worth noting. YouTube TV is unsupported, some apps run only as web versions, and Google or Motorola smartphone users will need a Chromecast dongle for screen mirroring. The USB port also lacks sufficient power for streaming sticks, requiring an additional power adapter. These are relatively minor inconveniences but worth factoring in depending on your existing devices.

Overall, the Lisowod L61Pro 2.0 is an impressive all-in-one projector that punches well above its weight class. Its combination of smart AI features, strong audio, official app support, and genuine portability makes it one of the most well-rounded options available for both indoor and outdoor use. If you want a single device that replaces a TV, soundbar, and streaming stick, this projector deserves serious consideration.

The Lisowod L61Pro 2.0 is best suited for users who want an all-in-one entertainment solution without needing a separate streaming device, soundbar, or complicated setup. It is particularly well-matched for outdoor movie nights, apartment living where a large TV is impractical, and families who move their viewing setup between rooms.

What to consider before buying: If you rely heavily on YouTube TV or prefer full native app experiences for every streaming platform, be aware that some apps run in web-only mode. Google Pixel and Motorola users will also need to budget for a Chromecast dongle to enable screen mirroring. If you plan to use a Fire TV Stick or Chromecast, have a USB power adapter on hand since the projector's built-in USB port may not deliver enough power.

Ideal use cases: Backyard or camping movie nights, home theater setups in living rooms or bedrooms, gaming sessions that benefit from the dedicated Game mode, and any scenario where portability and quick setup are priorities. The 300-inch maximum screen size and 50W audio make it equally capable for small gatherings as for personal use.

Comparing to alternatives: At its price point, few portable projectors offer a built-in smart OS with official licensed apps, 50W Dolby Audio, and a full suite of AI image correction tools together. If raw brightness for brightly lit rooms is your top priority, you may want to compare against dedicated home theater models, but for versatility and portability, the L61Pro 2.0 is a strong contender.

The HAPPRUN 2000 ANSI 4K projector is a feature-rich portable projector designed for home theater enthusiasts, outdoor movie lovers, and anyone seeking convenient wireless projection without technical expertise. Its combination of high brightness, intelligent automation, and multi-device compatibility makes it suitable for families, gamers, and content creators looking for flexible viewing options.

The standout feature is the AI-powered auto-focus and 6D keystone correction system that eliminates manual calibration entirely. Setup takes just 5 seconds from power-on to perfectly aligned image, whether mounted on a table, wall, or ceiling. The 2000 ANSI lumens brightness delivers impressive clarity for both dark evening viewing and outdoor daytime use, while the 20000:1 contrast ratio and 95% color gamut ensure rich color depth and detail that rivals dedicated home theater systems.

The ViewSonic PA503S is an SVGA business projector designed for professionals who need reliable, bright visuals in meeting rooms, classrooms, training spaces, and corporate events. With 4,000 ANSI lumens of brightness and a large projection range of 80 to 150 inches, it caters to users who prioritize visibility over pixel-perfect resolution.

The standout feature of this projector is its impressive brightness. At 4,000 ANSI lumens, the PA503S holds its own even in rooms where controlling ambient light is difficult, making it far more practical for everyday office and classroom use than dimmer alternatives. SuperColor technology further enhances image quality by delivering a wide, vibrant color gamut that makes presentations and media content look polished and engaging.

Setup is refreshingly straightforward thanks to the 1.1x optical zoom, 0.8x to 2.0x digital zoom range, and vertical keystone correction. Whether you are mounting it on a ceiling or placing it on a table, getting a properly aligned image takes only a few minutes. The 1.9 to 2.1 throw ratio is well suited to standard-sized rooms, and a 100-inch image can be achieved from just 13 feet away.

The main trade-off is resolution. SVGA at 800x600 pixels is noticeably softer than modern 1080p or even WXGA projectors, and users displaying detailed spreadsheets or fine text may find it less crisp than desired. Additionally, as a lamp-based DLP projector, eventual lamp replacement is a maintenance cost to factor in over time.

Overall, the ViewSonic PA503S delivers excellent value for budget-conscious buyers who need a bright, easy-to-use projector for business presentations and educational settings. Its combination of high lumens, large screen capability, and user-friendly setup makes it a dependable workhorse, provided you can accept the SVGA resolution limitation.

Resolution: SVGA (800x600p), suitable for standard presentations and video content in professional environments.

Brightness: 4,000 ANSI lumens, providing clear and vivid images in both dim and moderately lit rooms.

Throw Ratio: 1.9 to 2.1, with a projection distance of 10.5 ft to 19.6 ft for screen sizes between 80 and 150 inches.

Refresh Rate and Latency: 120Hz refresh rate and 16ms input latency for smooth, responsive image rendering during fast-paced video or presentations.

Zoom and Adjustment: 1.1x optical zoom, 0.8x to 2.0x digital zoom, and vertical keystone correction for flexible and easy image alignment.

Connectivity: HDMI input for seamless connection to laptops, media players, and other modern source devices.

Color Technology: ViewSonic SuperColor for an expanded color gamut and enhanced visual accuracy.

If you are shopping for a projector primarily for business presentations, training sessions, or classroom instruction, the ViewSonic PA503S is a strong contender in its price range. Its high brightness makes it far more versatile than lower-lumen models, especially in spaces where you cannot fully dim the lights.

Consider this projector if your content consists mainly of slideshows, documents, videos, and web-based material. The SVGA resolution is adequate for these use cases, though if you regularly work with highly detailed graphics, CAD drawings, or 4K media, you may want to invest in a higher-resolution model such as a 1080p or WUXGA projector.

For buyers comparing lamp-based versus laser projectors, keep in mind that lamp replacements add to the long-term cost of ownership. If you plan to use the projector heavily every day, a laser projector may offer lower maintenance costs over several years. However, for moderate use in meetings and classes, the PA503S lamp life should provide years of reliable service before replacement is needed.

The HDMI input makes it compatible with virtually any modern laptop or media device, and the easy keystone and zoom controls mean you do not need a dedicated AV technician to set it up. This makes it an excellent choice for small businesses, schools, and organizations that need plug-and-play simplicity without sacrificing image brightness.

The ViewSonic PA503W is a WXGA DLP projector designed primarily for classrooms and business presentations, though its fast refresh rate also makes it appealing to casual gamers. With 4,000 ANSI lumens of brightness, it's built to perform well even in rooms with some ambient light, making it a practical choice for offices, training rooms, and lecture halls.

What really sets this projector apart is its 120Hz refresh rate combined with a 16ms input latency, features you don't typically see in budget business projectors. This means presentations with video, animations, or even light gaming sessions look smooth and responsive rather than choppy or delayed. SuperColor technology further enhances the experience by producing a wide color gamut, so charts, images, and video content appear vibrant rather than washed out.

In terms of design, the PA503W is straightforward and functional rather than flashy. It supports ceiling mounting with ViewSonic's own PJ-WMK-007 mount, and setup is simplified through 1.1x optical zoom, 0.8x-2.0x digital zoom, and vertical keystone correction. It can throw a 100-inch image from just 11 feet away, and scales up to 150 inches for larger venues, giving it solid flexibility for different room sizes.

The main tradeoff is resolution: at 1280x800, this is a WXGA projector, not Full HD, so extremely fine text or detailed graphics won't be as crisp as on higher-resolution models. It also relies on a traditional lamp rather than LED or laser, meaning users will eventually need to budget for bulb replacement. The relatively modest optical zoom range also means placement needs to be planned more carefully than with projectors offering longer zoom ranges.

Overall, the ViewSonic PA503W is a dependable, well-rounded projector for anyone needing a bright, large-screen display for presentations, teaching, or meetings. Its combination of brightness, low latency, and easy setup make it a strong value pick, especially for schools and small businesses that don't require 4K-level detail.

The BenQ TH671ST is a purpose-built gaming projector designed for console gamers and home entertainment enthusiasts who want cinematic experiences without sacrificing performance. With its ultra-low 16ms input lag and DLP technology, this projector targets serious gamers on PS4, Xbox One X, Nintendo Switch, and other platforms who demand responsive gameplay on the big screen.

The standout feature is its short-throw capability, projecting 100-inch images from just 5 feet away thanks to a 0.69-0.83 throw ratio. Combined with 1.2x zoom flexibility, the TH671ST works in compact living rooms where traditional projectors fail. Its 3000-lumen brightness with 92% Rec.709 color accuracy ensures vibrant visuals even in well-lit spaces, while the Game Mode fine-tunes shadow detail and clarity for competitive play. The automatic LumiExpert detection actively adjusts image quality based on ambient light, reducing eye strain during extended gaming sessions.

Build quality reflects BenQ's reputation with a compact 2.7kg design, dual HDMI inputs for console connectivity, and vertical keystone adjustment for flexible mounting. The projector supports up to 1080p 60Hz 3D content and includes comprehensive connectivity options. Performance is solid across picture modes, though the native 1080p resolution shows limitations on very large screens, and the 5W speaker requires supplemental audio for immersive gaming soundscapes.

Minor drawbacks include lamp replacement costs despite the extended 15,000-hour LampSave mode, and the absence of 4K support limits future-proofing for next-generation consoles. However, the 3-year warranty and US-based support provide confidence in long-term ownership and service reliability.

The BenQ TH671ST delivers excellent value for console gamers seeking big-screen action in space-constrained homes. Its combination of low input lag, short-throw projection, and bright image quality makes it a top choice for PS4 and Xbox players, though 4K enthusiasts should consider higher-end models for future content compatibility.

This projector excels in gaming environments with its 16ms input lag and microsecond DMD response time, eliminating the motion blur and lag that plague casual gaming setups. The Game Mode picture preset specifically enhances shadow detail and visual precision, giving competitive players an advantage in dark scenes and fast-paced action sequences.

Console compatibility is comprehensive, supporting PS4 Pro, Xbox One X, Nintendo Switch, and Google Stadia with dual HDMI 1.4a inputs. The refresh rate matches console output specifications, ensuring smooth frame delivery without stuttering or tearing. For esports titles and fast-action games, the low input lag maintains the responsiveness players expect from dedicated gaming monitors.

The 1080p resolution is sufficient for console gaming on screens up to 100 inches, though competitive players in larger rooms may notice some pixelation. The projector's 10,000:1 native contrast ratio delivers punchy blacks and bright highlights, enhancing visual impact during intense gaming moments.

Display Technology: DLP projection with 1.07 billion color support and RGBYCM color wheel at 2X speed (50Hz/60Hz)

Resolution: Native 1080p (1920x1080) with support up to WUXGA-RB (1920x1200), 92% Rec.709 color accuracy

Brightness and Contrast: 3000 ANSI lumens, 10,000:1 native contrast ratio for vibrant images in any lighting condition

The Epson EX3290 is a business-oriented 3LCD projector designed for professionals, educators, and home users who need a bright, reliable display in a variety of lighting environments. With its WXGA resolution and 300-inch maximum image size, it bridges the gap between office presentations and casual home entertainment.

The standout feature here is undoubtedly the 4,000-lumen brightness, rated for both color and white output. This is a meaningful distinction because many projectors advertise high white brightness while delivering washed-out colors in lit rooms. The EX3290 holds up well in conference rooms and classrooms without requiring blackout curtains.

Epson's 3-Chip 3LCD technology is a genuine advantage over single-chip DLP alternatives. By dedicating a separate chip to each primary color, the projector displays 100% of the RGB signal in every frame, resulting in accurate, vibrant color reproduction. Users sensitive to the rainbow effect found in DLP projectors will appreciate this design.

On the connectivity side, dual HDMI ports are a practical touch that simplifies multi-device setups. The built-in speaker further reduces setup friction, though it is best suited for smaller rooms and intimate meetings rather than large auditoriums. The WXGA resolution, while sharp enough for presentations and video, falls short of Full HD, which is worth considering for dedicated home cinema use.

Overall, the Epson EX3290 delivers strong real-world performance for its category. It is an ideal pick for small business owners, teachers, and hybrid workers who want a bright, color-accurate projector that is quick to set up and easy to move around. Those prioritizing 1080p or 4K resolution for movie watching may want to look at higher-tier options.

Resolution: WXGA (1280 x 800), 16:10 widescreen aspect ratio, suitable for modern laptop and presentation content.

Brightness: 4,000 lumens of color brightness (IDMS rated) and 4,000 lumens of white brightness (ISO rated), ensuring consistent performance in ambient light conditions.

Display Technology: 3-Chip 3LCD, delivering 100% RGB color signal per frame with no color wheel and no rainbow effect artifacts.

Connectivity: Two HDMI ports compatible with laptops, Amazon Fire Stick, Apple TV, Roku, Chromecast, and other HDMI-enabled streaming or computing devices.

Audio: Built-in speaker included for immediate out-of-box audio without requiring external speakers. Image Size: Supports projection sizes up to 300 inches, approximately 4x the display area of a 75-inch flat panel screen.

If you are comparing projectors in the $400 to $600 range, the key factors to weigh are brightness, resolution, and connectivity. The EX3290 excels in brightness and color accuracy, making it a top contender for office and classroom environments where lights stay on during presentations.

For home theater buyers, it is important to note that WXGA resolution is one step below Full HD (1080p). If your primary use case is watching 4K or Blu-ray content in a darkened room, you may benefit from investing in a 1080p or 4K projector. However, for streaming, gaming, and casual movie nights in a living room, WXGA is entirely acceptable at typical viewing distances.

The dual HDMI ports are a practical advantage for users who frequently switch between a laptop and a streaming device. If you regularly present from a laptop while also wanting to run a Roku or Apple TV, the EX3290 saves you the hassle of constantly swapping cables.

Consider the long-term cost of lamp replacement when budgeting for any traditional lamp-based projector. Epson replacement lamps are widely available, but factoring in that cost over a multi-year ownership period gives you a more accurate picture of total cost of ownership compared to laser projectors.

The ViewSonic PS502W is a WXGA short throw DLP projector built specifically for business and education environments. With a 0.52 throw ratio and 4000 ANSI lumens of brightness, it is engineered to deliver large, clear images in real-world spaces where ambient light and limited room depth are common challenges. It targets educators, corporate presenters, and AV coordinators who need a dependable, cost-effective alternative to large flat-panel displays.

The standout feature of the PS502W is its short throw capability, projecting a 100-inch image from just 4.5 feet away. This design keeps presenters out of the projector beam entirely, eliminating the eye glare and shadow interruptions that plague standard throw projectors. Combined with ViewSonic's SuperColor technology, the image quality is vibrant and true-to-life, making it well-suited for data-heavy slideshows, video content, and educational materials alike.

Connectivity is thoughtfully handled with dual HDMI ports, a USB-A power output for wireless dongles, and easy one-button source switching. The built-in 16W speaker is a practical inclusion that covers audio needs for most classroom and meeting room scenarios without requiring additional equipment. Setup is further simplified by digital zoom, vertical keystone, and auto keystone correction, reducing installation headaches significantly.

The primary drawback is the WXGA (1280x800) resolution, which falls short of full 1080p. For most presentation and instructional use cases this is acceptable, but users displaying high-resolution video or detailed graphics may notice the limitation. Additionally, like all lamp-based projectors, eventual bulb replacement is a maintenance consideration, though the 12,000-hour Eco mode lamp life is generous and helps defer that cost considerably.

Overall, the ViewSonic PS502W delivers a compelling package for its price point. It balances brightness, short throw convenience, and practical connectivity in a way that directly addresses the needs of teachers and business professionals. For anyone seeking a large-screen projection solution for a small-to-medium room without breaking the budget, this projector is a strong and well-rounded choice.

Resolution: WXGA (1280 x 800p), providing a widescreen 16:10 aspect ratio suitable for standard presentation slides and educational content.

Brightness and Contrast: 4000 ANSI lumens of light output with a high contrast ratio, ensuring images remain clear and vibrant even in rooms with significant ambient lighting conditions.

Throw Ratio and Distance: 0.52 short throw ratio. Projects a 100-inch image from approximately 4.5 feet (1.1 meters). Supports screen sizes from 80 inches to 150 inches at throw distances of 3.6 to 6.7 feet, and up to 300 inches maximum.

Connectivity: Dual HDMI inputs for simultaneous multi-device connection, USB-A port for powering wireless HDMI dongles and performing firmware updates via computer.

Audio: Built-in 16W mono speaker. Image Adjustment: 0.8x to 2.0x digital zoom, vertical keystone correction, and auto keystone. Lamp Life: Up to 12,000 hours in Eco mode. Technology: DLP lamp-based projection.

If you are evaluating the PS502W for a classroom or conference room, the most important factor to consider is room size. The short throw design excels in spaces where the projector must sit close to the wall or screen, making it ideal for smaller rooms, interactive whiteboard setups, or environments where a ceiling mount is not practical.

For buyers comparing this to flat-panel displays, the PS502W offers a dramatically lower cost per screen inch at sizes above 80 inches. A comparable 100-inch or larger display would cost several times more, making this projector an economically smart choice for schools and businesses with tight AV budgets but a need for large-format visuals.

Consider the resolution carefully if your use case involves displaying high-definition video or intricate graphics. WXGA is excellent for presentations, documents, and standard educational content, but if 1080p fidelity is a priority, you may want to explore higher-resolution alternatives in ViewSonic's lineup. For the majority of typical classroom and boardroom scenarios, however, the PS502W's resolution is more than adequate.

Finally, factor in the total cost of ownership. The lamp will eventually need replacement, so budget for that over a multi-year horizon. The Eco mode's 12,000-hour rating is generous and means most users will go years before needing a replacement. The USB firmware update feature also means you can keep the projector current without service visits, which is a meaningful long-term convenience for IT administrators managing multiple units.

The ViewSonic LSD400HD-ST is a 1080p laser projector built for commercial, educational, and simulation environments where space is tight but brightness and reliability matter.

Standout features include 4,000 ANSI lumens paired with a 3,000,000:1 contrast ratio, which keeps text and visuals sharp even under ambient lighting. The dedicated Golf Simulation Mode is a notable extra, tuning color output to better render greens and fairways for training or entertainment setups, something few general-purpose projectors offer.

Build quality leans toward durability and uptime rather than home theater aesthetics. The IP6X sealed optical engine and laser phosphor light source, rated for 20,000 hours, are designed for continuous 24/7 operation without the bulb swaps traditional projectors require, and the unit supports 360° projection and portrait mode for flexible mounting.

On the downside, this is a business-first device: there's no smart TV interface, and at this price point it's clearly targeting institutional buyers over casual consumers. With zero reviews so far, buyers are relying on ViewSonic's specs and reputation rather than field-tested feedback.

Overall, the LSD400HD-ST is a compelling choice for AV integrators, schools, and golf simulator installers who need a bright, low-maintenance, short throw projector with professional network control. Home users seeking a simple plug-and-play theater projector will likely find better value elsewhere.

Native resolution is a true 1920x1080 with support for image sizes ranging from 40 to 300 inches, and a throw distance range of 0.44 to 3.29 meters, giving installers flexibility across small and large rooms.

Connectivity covers HDMI, USB 2.0 Type-A, Ethernet, and 3.5mm audio, along with H.264 and H.265 video decoding for direct network media playback. It draws 143 watts and weighs 6.8 pounds, making it reasonably compact for ceiling mount installations.

Professional integration is supported through Crestron and Q-SYS certification plus compatibility with AMX, Extron, and PJ Link, allowing centralized LAN-based monitoring across multiple units. The unit ships with a power cord, remote, and user manual, backed by a three-year limited warranty on parts, labor, and the laser light source.
