I am looking for a way to set custom resolution on Windows PC to make it artificially hide parts of the screen. Display I am using is 55" TV connected via HDMI cable. I already tried using CRU by ToastyX but without success. I try to explain with picture below.
Any ideas? What I am doing wrong?
I tryed using CRU and playing around with resolution but that resulted only in black bars around screen. I mostly changed parameters in Active.
