Monitor display issues

[Mh259901]

Screen displays pixelation and buzzes. The display is darker and the dark pixels slowly move up the screen and then it glitches, showing vertical bars of distorted pixels at the top and bottom. Have tried a different HDMI cable and monitor but it's definitely an issue with the monitor. Also tried updating drivers. Before this the strip of LEDs right at the top was glitchy sometimes. Bought this new last autumn but it was the display model I think.
