Customer Reviews

3840 x 2160 4K UHD Smarthome Projector Amazon Alexa Integration with 2400-Lumen is rated 3.0 out of 5 by 1.
Rated 3 out of 5 by from Solid UHD Projector with critical flaw. I've owned the UHD51A for a few months now. I use it primarily for PC gaming in 3D, 4K tv watching (and occasionally gaming at 120Hz in 2D) on a 140" screen. I spend most of my time in 3D modes with my projectors. Image quality is great and 2D games really shine in 4K. Even 1080p content looks good from close distance due to the higher overall number of pixels fitting on the screen. Much better than my previous 1080p projector from 10-12 feet away. Blu-ray 3D movies also look fantastic playing on a PS3 (1080p). Overall, I've had no serious issues with the 3D functionality except for one KEY thing: Frame sequential 3D support is missing or disabled. This means I cannot play 3D games in higher resolutions from a PC at 1080p. I have to settle for software modes (like nVidia's 3D tv play) that only work in 720p for a decent refresh rate (60fps and above). Older Optoma projectors as well as current lower tier models have frame sequential mode as an option, so not sure why it's not included on this UHD/3D marketed model. Pairing the increased UHD pixel count with a maximum 720p resolution in 3D seems like a limiting combo. For some people, being able to watch 2D content in 4K and 3D movies on the same machine is good enough. For those people, I think this projector is a winner as it does both of those basic things very well. As a 3D gamer, though, the UHD51A's lack of frame sequential 3D support is both limiting and head scratching...especially since they are still including in other newly released models. Hopefully this is an oversight that can be corrected with a firmware update. If that's the case, even with some other minor issues (like wifi support, Alexa problems, etc) the enabling of frame sequential 3D mode would be enough to check all of the major boxes for me and many other 3D gamers. That would make this a 5-STAR product in my eyes and the ultimate 3D gaming projector that I was going for when I purchased it.
