Yea i actually did. It came up with my 120Hz and could see the 60Hz moving choppy compared to 120Hz. Ive also noticed that at 144hz my tv sometimes flashes back randomly so i dont leave it at that setting. I think more testing needs to be done for sure with more monitors and tvs. My 2nd monitor will only get up to 77Hz from 60Hz original. I have an ols one the will do 75Hz stock soni want to test that one tonight.
