Same model as me, like you, no complaints (well until I had to send it back for repair when the HDMI board went south)I run an optoma uhd300x on a 130" screen for my Xbox 1x and PC.
4k image looks great. Its not real 4k like a TV panel but still looks damn good.
HDR performance is not bad.
Relatively quiet unit. Mine is ceiling mounted just behind sitting position. I can definitely hear it when volume is down on whatever it is I am watching but mostly wear headphones so non issue.
Playing doom eternal on PC at 4k settings and HDR on 130" screen is pretty epic. And the uhd300x can be found for under £900.
But, the 4k picture quality and HDR is not up to a modern oled/qled panel. But size makes up for it.
