Hi there... I'm returning to gaming scene. My current screen is 27" 4k ips 60hz screen and today i'm getting a used 27"1440p 144hz TN monitor. Then i started thinking.. How will it effect my FPS if I run my 4k@60hz pararel to my 1440p@144hz while gaming. Will it effect anything ? Should i switch my 4k to 1440p when gaming ? Or should i just disconnect my 4k as it's 60hz ?
