Optoma UHZ65 got recommended award  from avforums.

“If we look at the Optoma against the existing 4K DLP projectors on the market then it is clearly the best we have seen to date, given the improved black levels and colour gamut.

“The other strength of DLP is brightness and the UHZ65 is an excellent choice for a normal living room environment with light coloured surfaces and some ambient light spill (just not directly on screen).”

“To date this is the best 4K DLP projector we have seen”
