10 Best 4K Projectors

The BenQ GP520 is a solid choice for a 4K projector designed mainly for home entertainment. It offers sharp 4K UHD resolution with HDR10+ support and a brightness of 2600 lumens, which means you can expect clear and vibrant images, especially in moderately dark rooms. The inclusion of Rec.709 color accuracy and BenQ’s CinematicColor technology helps deliver rich and true-to-life colors, adding to the viewing experience. Its brightness level is good for living rooms that can be dimmed but might struggle in very bright environments.

One of the standout features is the Auto Cinema Mode, which intelligently adjusts image quality based on lighting conditions without needing manual changes. This makes it convenient for users who want great picture quality without fuss. The projector also supports gaming with low input lag and ALLM (Auto Low Latency Mode), making it responsive enough for casual gaming. Setup is flexible, with multi-angle installation options and smart image alignment, so you can place it on a table or mount it easily. It’s relatively portable at 3.7 kg and includes built-in 12W stereo speakers, which provide decent sound for most rooms, though connecting external speakers via Bluetooth is available for a better audio experience.

Connectivity options cover the basics well, including USB, HDMI, Bluetooth 5.2, and audio out, allowing connection to laptops, gaming consoles, and streaming devices. The built-in Google TV is a plus for streaming content directly without extra devices. While 2600 lumens is good, it’s not the brightest in its class, so very bright rooms could wash out the image. Noise level at 24 dB is fairly quiet but might be noticeable in very quiet environments. The BenQ GP520 is a versatile 4K projector well suited for home cinema lovers looking for sharp picture quality, easy setup, and built-in streaming, though it may be less ideal for brightly lit rooms.

The BenQ X3100i is a solid choice if you’re looking for a 4K projector mainly for gaming and home cinema. It offers true 4K UHD resolution (3840 x 2160 pixels) with vivid colors thanks to 100% DCI-P3 color coverage and HDR-PRO support, which means images are sharp and bright with good contrast. Its 3300 lumens brightness rating ensures clear viewing even in moderately lit rooms, making it versatile for different lighting conditions. The contrast ratio of 600,000:1 ensures dark scenes have good depth and detail, enhancing movie or game visuals.

For gamers, the projector excels with very low input lag and a fast 4ms response time at 1080p 240Hz, allowing smooth and lag-free gameplay — a key factor for console gaming. The throw ratio and vertical lens shift features make it easier to set up the projector in various room sizes and positions, adding flexibility. Connectivity options include Bluetooth, Wi-Fi, USB, and multiple HDMI ports, so you can easily connect consoles, laptops, and smartphones. It also includes Google Android TV for streaming apps, plus AirPlay and Chromecast support for casting, making it an all-in-one entertainment hub.

Audio is another strong point, with built-in 7.1-channel Dolby Atmos sound and eARC support, delivering immersive sound without needing extra speakers. The projector weighs 6 kg and is designed for tabletop use, so it is less portable and not ideal if you want to move it around frequently. The BenQ X3100i delivers bright, clear 4K visuals with excellent gaming performance and versatile smart features, but you should consider your setup space before buying.

The BenQ X500i is a strong choice if you're looking for a 4K projector primarily for gaming and home cinema in smaller spaces. It delivers true 4K resolution (3840 x 2160) with excellent color accuracy thanks to 100% DCI-P3 and HDR-PRO support, resulting in sharp and vibrant images. Its brightness of 2200 ANSI lumens is decent for dim to moderately lit rooms, providing clear visuals without needing total darkness. The impressive contrast ratio of 600,000:1 adds depth to dark scenes, enhancing movie and game experiences.

One of the standout features for gamers is the very low input lag with a 4ms response time at 1080p and a high refresh rate of 240Hz, which means smooth, lag-free gameplay—ideal for fast-paced console games on Xbox, PS5, or Switch. The short throw ratio (0.69~0.83) lets you project a large image from a close distance, making it perfect for bedrooms or small living rooms where space is limited.

Connectivity is versatile with Bluetooth, HDMI, USB, and Wi-Fi, plus built-in Android TV, AirPlay, and Chromecast support, so you can easily stream content or connect various devices without hassle. The audio experience is enhanced by built-in 7.1-channel Dolby Atmos speakers, which is rare in projectors and means you won’t need extra sound equipment for immersive sound. While the brightness might not be enough for very bright rooms and some users sensitive to the 'rainbow effect' from DLP technology might notice this, the projector operates relatively quietly at 33 dB, making it a great fit for gamers and home cinema enthusiasts with limited space who want a hassle-free, immersive experience.
