Display and Image Quality
The UHD35STx boasts an incredible True 4K UHD resolution (3840×2160) through its DLP™ display technology. With a brightness of 3,600 lumens and a contrast ratio of 1,000,000:1, the projector delivers stunningly bright and high-quality images. The native aspect ratio of 16:9 ensures that the visuals are properly displayed without distortion, and the 80% uniformity ensures consistent brightness across the screen.
We tested the projector with various 4K content, including movies, TV shows, and games. The image quality was impressive, offering sharp and detailed visuals. The colors were vibrant and accurate, making the viewing experience truly immersive. However, we noticed that the black levels could be deeper, especially in dark scenes where details might get lost.
The UHD35STx is specifically designed to cater to gamers seeking a competitive edge. The projector supports 1080p 240Hz at 4.2ms and 4K 60Hz at 16.9ms, ensuring lightning-fast input lag and a high refresh rate. We tested the projector with several games at different settings, and the low input lag and high refresh rates were indeed noticeable. The projector provided a smooth and responsive gaming experience, free from the ghosting or motion blur that can sometimes plague other projectors. However, for some fast-paced games, we observed minor input lag at 4K 60Hz.
Short Throw Projection
One of the standout features of the UHD35STx is its short throw projection capability. With a throw ratio of 0.5:1, the projector can create a supersized 100″ image from just a few feet away. We tested this feature in a small room, and we were impressed by how the projector could produce a large, clear image even in a tight space. This makes the UHD35STx an excellent choice for users with limited space or those who want to create an immersive gaming or movie-watching experience without needing a large room.
The UHD35STx features a built-in 10W speaker, which provides decent audio quality for casual use. However, for a more immersive audio experience, we recommend connecting external speakers or a home theater system through the 3.5mm audio output or the S/PDIF output. The built-in speaker could use improvement in terms of bass response and overall sound clarity, especially at higher volumes.
The UHD35STx offers a variety of connectivity options, including 2 HDMI 2.0 inputs, a 3.5mm audio output, S/PDIF output, and a USB-A power port. There is also an RS232 control port and a 12V trigger for advanced control and integration with home automation systems. The projector is compatible with a wide range of resolutions and devices, including PCs, Macs, and gaming consoles. The inclusion of more HDMI ports would have been a welcome addition for users with multiple devices.
