Using the whole screen size

Hello,

I have a RPi4 running the Fullscreen Browser package to display two webpages, I’ve had to rotate the display 90° because of the TV setup. Previous to info-beamer, we had to zoom in, I think. Is there a way to do this with info-beamer config?

Display is a 3840x2160 TV that’s turned sideways.

Any help would be appreciated, currently it looks like this:

Low tech solution: Could you use FullHD instead of 4K for this content? Depending on display placement the difference might not be noticeable and the content should be a lot bigger as a result. If that’s not possible, let me know.

Changing it to 1080 worked perfectly, thanks Florian.
