Seems your projector doesn't play 4k content. It accepts 4k but it will down sample to full HD.

The $649 Optoma HD27HDR gives away the big news about itself with its three-digit price and the three-letter acronym in its name: HDR. At this writing it is the only projector on the planet that costs anything like the price, supports HDR10, and can accept 4K input. Connect it to, say, a 4K Blu-ray player, and you can watch a 4K HDR movie with the benefits of HDR, even though the projector will downsample the resolution to its native 1080p.
