No matter what I try with my gaming PC setup, I could not get this balanced right. It detracts from the sharpness of my 4k gaming or movie watching. I can't turn it off, either. For some strange reason, they thought it would be ok not to have a power button on this and rely solely on the PC turning off or going into sleep mode. This does not work for me as I need the computer to be on and responsive even when I am heading to bed and I don't want the screen to shine like the sun as I try to sleep.
