I currently have a 60hz monitor and im planing on getting a new 120/144hz for gaming. but then i was thinking about keeping my own old one, does it make anything weird with 2 not same hz monitors or does it work np? Asus GTX 970 STRIX oc
no it wont be any problem with 2 different Hz on 2 monitors, i already have a 144hz as gaming and 60hz for browsing, you wont use both for gaming but one for gaming and one for spotify/chat/browsing.
BUT, if you gonna do 3 monitors for gaming then you should have all 3 the same monitor.
