Hello there, I have read a lot of posts on this topic but none of them seem to fix my problem. I have an OMEN by HP 27 monitor and I have it connected to my PS4. When I turn it on it says, "Optimal mode: 60hz". I tried changing the Hz by connecting the monitor to my MacBook air 13 inch but when I tried changing the Hz, 60 was the maximum and I could only lower it to 52. Any way that I could change the Hz on my monitor? Thank you!
