Question black line edges of screen

[Go619007]

I have a new 27-inch Acer ED273U monitor, and it's a 2K monitor.

It shows black edges like this, and these edges are fixed like this

and this to

No matter how much I try to adjust the screen settings, these edges are fixed, and these edges do not change from the sides and the top of the screen only, but the bottom of the screen is just right

The dimensions used are the original 2560 * 1440 with a refresh rate of 144Hz although the screen is supposed to support up to 165Hz but it does not appear in the options when I edit in this image

This is also a picture of the card settings

The cable used is the HDMI attached to the monitor, which is version 2.0

The graphics card used is ROG-STRIX-GTX1080TI-O11G-GAMING

I don't know why this problem exists and it is assumed that these edges are not present (also the refresh rate is supposed to support the screen up to 165Hz as mentioned on the carton why in Windows the maximum is only 144) Is it because of the HDMI cable or what

You will need to use DP to gain access to 165Hz in refresh rate. See if that changes your experience.

hmm I think your are somewhat correct about 165 Hz , given the information provided here
Vertical Frequency:
48 Hz to 144 Hz – HDMI
48 Hz to 165 Hz – DisplayPort
but do you think if i use cable DP would solve the other problem black line edges of screen ??
