Is This Normal? My new projector's picture is dull even though I paid for 4K

1•SorabAlavi•1h ago
Hey everybody, need some hive mind help. Finally upgraded to a 4K projector after years on a 1080p one, but I'm hitting a wall.

The image is sharp, sure, but the colors feel flat and the blacks are more like dark grays, even in a dim room. It doesn’t have that “pop” I was expecting. My setup is pretty basic: projector straight onto a light grey wall.

I know the wall isn't ideal, but could it really be the main culprit holding back a decent projector? I’ve been down a research rabbit hole and keep seeing “ALR screen” come up as a game-changer for contrast.

For those who made the jump from a wall to a proper screen:

Was the difference really that dramatic? Was it a subtle improvement or a “holy crap” moment?

Any brand/model recommendations for a living room with some ambient light? I’ve seen the brand VIVIDSTORM pop up a few times in discussions—anyone have real experience with their screens, good or bad?

Just trying to figure out if my next investment should be in a screen or if I need to troubleshoot the projector itself. Thanks for any wisdom!

A projector cannot take light away. So unless your room is truly dark (no candles even), you cannot expect black. “Dim” is not nearly enough.
