Just received an 8350 off ebay, like new condition. I booted it up and plugged in my computer and there's some major posterization going on. Any sort of gradational color scheme looks like a 256 bit bitmap. I'm plugged in through hdmi from my computer. I've tried two other computers, a stick-pc, and a total of 3 hdmi cables. I called Epson and they said that it sounds like a HDMI hardware problem. I've tried adjusting levels and sources, nothing helps.
Anyone else encounter this? I'm going to send it back.
