Can't turn on UHD

Hi, I am not able to turn on the uhd setting, as soon as I turn on uhd the four corner keystone gets distorted and if I correct them the UHD gets turned off. Don’t know how to solve the issue

Hello, the Gaming mode and UHD mode cannot be used while 4 corner correction is ON in order to use the max resolution of the screen.

And in the future would it support 4 corner correction, because it’s really annoying to watch with weird projection

Hello, please note that this won’t be possible.
We suggest to position the U4 in front of the wall in order to avoid using the 4 corner correction.

I am using projector screen, but still it doesn’t project correctly , maybe you should improve auto keystone then, the experience of using screeneo is really becoming annoying day by day
