Question Annoying black bar when setting custom resolution.

[5wixy]

Hi, I've upgraded from 60hz to 165hz(massive change). Asus VG249Q1A monitor.
when i first installed the screen it was set us 1920x1080 with 144hz as default, which seemed weird to me so i kinda played with the setting and got it with custom 1920x1080 165hz.
But, when i use 165hz settings i get a small black bar across the lower border of the screen like this pic:

when i revert to 144 the bar disappears. also when in a fullscreened game, the black bar doesnt appear.
i tried to play with the settings again but gave up in the end.
any idea for solutions? thanks in advance

What's the Overclocking setting set to in the monitor?
and what are you driving it with? GPU or motherboard, and specs of each?

Also, if you look at the PC Timings List in the Manual, it shows that 1920x1080 at 165Hz is only available using the DisplayPort connection.

Thanks for the response, Its connected to my GPU which is a 3060Ti via display port.
idk if its important but the motherboard is Gigabyte B660M.
Im not sure about the overclocking settings though, but i didn't do anything myself.
