Bests & Worsts Reviews from Amazon

I've been anticipating the release of a $5,000 full UHD HDR projector for years. I've had the 665ES for almost 2 years and been pleased with the SDR video quality. The 665 was advertised as having HDR so much to my disappointment, when I plugged in a new 4K  TV the projector couldn't do the HDR unless I stepped down the refresh to 24hz to handle its 10-bit signal, which of course was unacceptable. I have 4 of them in 2 different homes. So when the 285 came out, I ordered 4 just so I could get the best quality from my 4K Apple TVs and Oppo 205 UHD HDR blu-ray player. I've had enough experience with Sony to trust that the 285 would be good, especially after reading the Projector Central review which was glowing. My four 665ES units would be going on eBay. Got the first 285 in last week and hooked it up to the  TV and turned on 10-bit HDR. Horrible banding issues in the menu on any graphical display of gradient color. Clearly visible and annoying in all content, which was eliminated only by switching the  TV back to SDR. Spent an entire day checking settings and changing them and searching forums. No dice. Watched latest episode of Star Trek: Discovery (on the CBS app only available in SDR) while in HDR mode on the  TV and it looked dark and too contrasty even after tweaking settings. Looked at it again in SDR mode and it looked fine. You're not supposed to have to switch between SDR and HDR mode on the  TV. It's supposed to do that conversion on the fly. Watched Saturday Night Live (1080i) on a TiVo Bolt in SDR connected to the projector at 4K resolution, and that looked fine. Watched the same show from Hulu on the  TV connected to the projector via HDR and it looked darker and more contrasty with the banding problem in gradated areas like graphics and logos. Switched the  TV to SDR mode and it looked fine. It appears the projector is displaying 8-bit color instead of 10-bit when the incoming HDR signal is above 30hz. If you don't know what banding is, there are only a limited amount of colors, so if you were to look at a sunset, for example, you would see only a few different colors spread across the screen in horizontal bands instead of a smooth gradual transition from bright to dark. So the problem is with how this projector handles 10-bit 60hz HDR. Serious blunder on Sony's part. This projector is defective and should be recalled unless a patch can be made via the Ethernet port.
