Additionally, the 10W speaker, while functional, may underwhelm in larger rooms. The 12.6-pound weight is heavier than some portable alternatives, though still reasonable for a feature-rich projector.
The ASUS H1 delivers exceptional value for gamers and home theater users prioritizing brightness, reliability, and gaming performance over 4K resolution. The 30,000-hour LED lifespan eliminates expensive lamp replacements, and customer reviews consistently praise its clarity and brightness.

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.

The ViewSonic PX701-4K is a true 4K UHD DLP projector designed for home theater enthusiasts and serious gamers who want a large-screen experience without investing in an oversized television. With a native 3840x2160 resolution, 3200 ANSI lumens, and support for both HDR10 and HLG, it positions itself as a versatile all-rounder that performs well in both darkened home theaters and moderately lit living rooms.
Where this projector truly stands out is in its gaming credentials. The 4.2ms input lag combined with a 240Hz refresh rate is genuinely impressive for a 4K projector at this price, putting it ahead of many competing models. Motion is smooth, fast-moving scenes remain sharp, and competitive gamers will notice a real difference compared to slower projectors. ViewSonic's SuperColor technology further enhances the experience by delivering a wide, accurate color gamut that makes both games and films look vivid and true to life.
Setup is made straightforward thanks to automatic horizontal and vertical keystone correction, 4-corner adjustment, and a built-in warping tool for curved surfaces. The 1.1x optical zoom offers some placement flexibility, though the range is modest. The projector supports ceiling mounting and can throw images from 30 inches up to a room-filling 300 inches, with a recommended maximum throw distance of 36 feet for a clear 300-inch image. Connectivity is practical, with dual HDMI ports, a powered USB-A output, and compatibility with most consoles, PCs, and streaming dongles.
On the downside, the absence of a built-in smart TV operating system means users must supply their own streaming device. The optical zoom range could be wider for greater installation flexibility, and the price point, while competitive for a true 4K gaming projector, is still a significant investment. Lamp-based projectors also require eventual bulb replacement, though the 20,000-hour SuperEco+ lifespan does mitigate this concern considerably.
Overall, the ViewSonic PX701-4K delivers a compelling combination of 4K image quality, gaming-grade responsiveness, and flexible setup features at a price that undercuts comparable large-screen TV alternatives. It is an excellent pick for anyone who wants the immersive thrill of a massive display for both movies and gaming, and is willing to add an external streaming stick to complete the setup.
Resolution: True 4K UHD (3840 x 2160p) with DLP display technology for sharp, pixel-dense imagery across all screen sizes.
Brightness and Color: 3200 ANSI lumens output with SuperColor technology, HDR10 and HLG support for enhanced contrast and a wide color gamut in varied lighting conditions.
Gaming Performance: 4.2ms input lag with a 240Hz refresh rate. Input lag activation requires enabling via advanced settings with the refresh rate set to 240Hz. Response time is based on the DMD chip.

Is this projector right for you? The ViewSonic PX701-4K is best suited to buyers who want a dual-purpose display for both home cinema and gaming. If you primarily watch films and sports, the true 4K resolution, HDR support, and high brightness will deliver a genuinely impressive picture. If you are a gamer, the 4.2ms input lag and 240Hz refresh rate are standout specs that rival dedicated gaming monitors on a much larger screen.
Room considerations: With 3200 lumens, this projector can handle rooms with some ambient light, but a darkened or dim environment will always produce the best contrast and color accuracy. Consider your room size carefully. The throw ratio of 1.5 to 1.6 means you will need roughly 11 feet of distance to project a 100-inch image, so measure your space before purchasing.
What you will need to add: This projector does not include a built-in smart TV platform, so plan to pair it with a streaming device such as a Chromecast, Amazon Fire TV Stick, or Apple TV. The built-in USB-A port conveniently powers these dongles without needing an extra wall adapter. A dedicated projection screen is recommended for the best image quality, though a flat white wall can work in a pinch.
Comparing alternatives: At this price tier, the PX701-4K competes with projectors like the BenQ TK700STi and Optoma UHD50X. Its 240Hz refresh rate and 4.2ms input lag give it a clear edge for gaming, while its SuperColor technology and HDR support keep it competitive for movie watching. If budget is the primary concern, entry-level 4K projectors are available at lower prices but typically sacrifice brightness, refresh rate, or input lag performance.
Pros
- Excellent low input lag makes it a top choice for competitive and casual gamers alike
- Bright 3500-lumen output performs well even with ambient light
- Built-in speaker delivers surprisingly good audio without external speakers
- Long lamp life (up to 15,000+ hours per user reports) and durable build
- Easy setup with auto keystone correction and flexible placement
Cons
- Automatically switches HDMI input when a connected device powers off, which can be inconvenient during gaming sessions
- Native 1080p resolution rather than true 4K, so detail lags behind laser projectors like the Epson EF12
- Focus can be finicky and overly sensitive, especially in ceiling-mounted setups
The BenQ TH685P is a 1080p DLP projector purpose-built for gamers who want a big-screen experience without sacrificing responsiveness. With 4K signal support, HDR10 compatibility, and a native 1080p/120Hz mode boasting just 8.3ms of input lag, it's designed to keep fast-paced titles feeling sharp and immediate. It's an excellent fit for gamers, casual movie watchers, and anyone tired of staring directly into a screen for hours.
In real-world use, the projector shines brightest in its gaming performance. Reviewers consistently praise its low latency for twitchy, competitive games, along with dedicated Game Mode and Game Sound Mode presets that fine-tune visuals and audio on the fly. At 3500 ANSI lumens, it holds up well even with some ambient light in the room, a rarity among projectors in this price range.
Build quality feels solid and long-lasting, with several long-term users reporting lamp life well beyond BenQ's stated hours and multiple TH685P/BenQ units lasting years without failure. The built-in 5W treVolo speaker with equalizer is a nice bonus, delivering usable audio without needing an external sound system for casual setups.
That said, it isn't without quirks. Several users note that the projector automatically switches HDMI inputs when a connected device powers down, causing brief blank screens or unwanted source switching mid-session. It also lacks true 4K resolution and laser-grade color accuracy, so detail-oriented movie watchers might find competitors like the Epson EF12 sharper for cinematic content.
Overall, the TH685P is a strong pick for gamers prioritizing responsiveness and brightness over ultimate picture fidelity. It's less ideal for videophiles chasing 4K detail, but for living room gaming, casual movie nights, or even office presentations, it offers excellent value and dependable performance backed by a solid 3-year warranty.
Pros
- Excellent 4K picture quality praised by multiple reviewers
- Very low input lag ideal for gaming
- Bright 4000-lumen output works well even with some ambient light
- Easy setup and compatible with standard mounting equipment
- Strong value compared to similarly specced 4K projectors
Cons
- Some users report recurring DMD dead pixel failures over time
- Lamp-based light source has a limited 10,000-hour lifespan and only a 90-day lamp warranty
- Heavier build than some predecessor models, which may complicate mounting
The Optoma UHD38x is a true 4K UHD projector aimed squarely at gamers and home theater enthusiasts who want a bright, responsive big-screen experience. With 4000 lumens of brightness, it's capable of producing a watchable image even in rooms that aren't fully dark, making it more versatile than many home-theater-only projectors.
Where this projector really stands out is gaming performance. A 4.2ms input lag at 1080p and a 240Hz refresh rate put it among the most responsive 4K projectors available, and support for 1080p 120Hz or native 4K 60Hz gameplay makes it a great match for the latest Xbox Series X|S and PlayStation 5 consoles. HDR10 and HLG support further round out the picture quality for both gaming and movie watching.
Build quality feels solid, with reviewers noting it's noticeably heavier and sturdier than Optoma's earlier HD146X model. Setup is straightforward, especially for anyone with prior projector mounting experience, and features like keystone correction help fine-tune image alignment on the fly.
The main concern comes from a handful of reviews reporting recurring DMD dead pixel failures after extended use, even after multiple manufacturer repairs. While this doesn't appear to be a widespread issue, it's worth keeping in mind, along with the fact that lamp life is rated at 10,000 hours with only a 90-day lamp warranty.
Overall, the Optoma UHD38x is a compelling choice for gamers and casual home theater users who want true 4K resolution, low input lag, and strong brightness at a reasonable price point. Just be mindful of the occasional reliability reports if long-term durability is a top priority.
What to Look for in a Gaming Projector
Refresh Rate and Input Lag
These two specs are the heartbeat of a gaming projector. A high refresh rate, like 120Hz or 240Hz, determines how many frames per second the projector can display, resulting in smoother motion and less blur. Input lag measures the delay between your controller input and the action appearing on screen. For fast-paced games, you want this number as low as possible, ideally under 20ms.
Models like the ViewSonic PX701-4K UHD Projector, 3200 Lumens excel here with a 240Hz refresh rate and 4.2ms input lag. It’s crucial to verify these specs for your specific console or PC setup. For more options focused on minimal delay, see our expert guide to the best 4K low input lag gaming projectors under $1000.
Brightness and Resolution
Brightness, measured in lumens, dictates whether you can game with ambient light in the room. Higher lumens combat washout from lamps or windows. Resolution defines image sharpness. While true 4K projectors in this price range are rare, many 1080p models support 4K HDR input for enhanced detail and contrast from your source.
The Optoma UHD38x Bright, True 4K UHD Gaming Projector offers a compelling combination with 4000 lumens and true 4K resolution. Consider your typical gaming environment; a brighter projector provides more flexibility if you can’t achieve total darkness.
Throw Distance and Setup
Your room size dictates the type of projector you need. Standard throw models require more distance between the projector and the wall. Short-throw models, like the BenQ TH671ST 3000 Lumens 1080p Short Throw Home, can project a large image from just a few feet away, making them ideal for smaller spaces.
Also, look for features that simplify setup, such as auto keystone correction, which automatically squares the image to your screen or wall. This eliminates tedious manual adjustments and gets you into the game faster.

Frequently Asked Questions
Is 120Hz enough for gaming on a projector?
Yes, a 120Hz refresh rate is excellent for gaming and represents a significant upgrade over standard 60Hz displays. It provides smooth motion for fast-paced action games and is the maximum output for current-generation consoles like the PS5 and Xbox Series X in their high-performance modes. For PC gamers with powerful rigs, some projectors in this category offer 240Hz for an even more fluid experience.
What is a good input lag for a gaming projector?
For competitive gaming, an input lag under 20 milliseconds (ms) is the target. Many projectors reviewed here achieve between 4ms and 17ms in their dedicated game modes, which is comparable to many gaming monitors. This ensures your actions feel instantaneous, giving you a tangible edge in reaction-based titles.
Can I use these projectors in a room with some light?
You can, but results depend heavily on the projector’s brightness. Models with 3000 lumens or higher, such as the BenQ TH685P or the Optoma UHD38x, will perform better in rooms with ambient light than lower-brightness models. For the best image quality, controlling light is always recommended, but brighter projectors offer more flexibility for daytime or casual gaming sessions.

Do I need a special screen for a high refresh rate gaming projector?
While you can project onto a plain wall, a dedicated projection screen will provide a sharper image with better color reproduction and contrast. The projector’s refresh rate and input lag are inherent to the device itself, not the surface you project on. Any quality screen suitable for home theater use will work perfectly fine to display the high frame rates.
