Get a good theater sound sytem and a 4K player (at this point only Samsung and Phillips are available - and the Samsung is better) a good screen can be had for $300.00 or

Above 120" screen size, most viewers will appreciate the increased sharpness of UHD content, but the screen will be dim enough that HDR content will either look washed out, or you'll have to calibrate the projector to maximize light output at the expense of color accuracy

Picture is awesome, better the my flat screen

I have it projecting onto a 140 inch Seymour Enlightor 4K acoustically transparent screen

beautiful picture paired with an acoustically transparent screen from Silver ticket

Since individual pixel brightness decreases as screen size increases, for screen sizes under about 120" the pixel structure of 1080p content will be invisible and the benefits of UHD will be marginal, but the screen will be bright enough to showcase the expanded color/brightness range of HDR

So this has plenty of lumens for daytime viewing, especially when combined with a good screen

The screen was so vibrant, that it looks like they were closed!I haven't had this projector for 24 hours yet, but will update my review as I find out cool new things.
