does/can Ued support 4k resolution?

I was going through the advanced settings of the OpenGL renderer in editor, and stumbled upon a 16 bit texture setting, does anyone have expirience with setting it to true and use 16 bit textures?

I think it makes it worse, I didn't try it but I assumed it would be for a windows screen running BPP set to 16, not 32.
Is my guess, so textures look right in 16 bit.
