In terms of performance the Optoma UHD51A is pretty typical of the 4K UHD projectors that are using the lower resolution 1920x1080x4 DLP chip. Where it separates itself from the pack at times is in other areas.

4K UHD resolution (1920x1080x4 DLP chip), 4K content capable, including HDR10, lower resolution of the two 4K UHD DLP chips, but nicely sharp, First projector to work with Alexa (won’t be the last) and Google Assistant, Works well enough but limited capabilities – so far, Expect more, RGBRGB color...

Black levels could be much better, Better than much of the DLP competition though, A bit low on brightness vs claim. Claim: 2400, max we measured 1982 lumens, I prefer remotes to be backlit – helps when lights are out, Warranty could be longer – 2 years, but BenQ and Viewsonic competitors have 3...
Projectors have countless advantages over TVs. For setting up a home theater, a projector allows your screen to be essentially as large as your wall. The resulting picture puts even giant TVs to shame. And size helps you see more detail.
Optoma doesn't cut corners with this entry-level UHD hero. Images are sharp, colour rich and dynamic, and there's the bonus of fine-looking 3D.
Ive had the UHD51A for about 5 months now and I am very pleased with it. I am using it in a finished basement with very low ambient light and a screen. I am coming from a Benq 1070w.Pros: The Optoma supports 4K and HDR which looks very sharp and vibrant, especially with 4K blu ray discs.
