So far this is not working with an Optoma UHD60 projector? All it sees is 1080p. Please help!
Super disappointed. I can plug my Sony 4K player into this projector with no issue. This will only show 1080p no matter what setting.
Make sure you are using a premium high speed cable capable of 4K/HDR (18GBPS). Try a different cable and port. Test on another display.
