Dell S2716DG - Single 1-2 pixel thick white horizontal line flashes/flickers every few seconds at the very bottom of the monitor mainly around where the Dell logo is, although it's often 2/3 width of the screen. Happens at 144hz and and custom resolutions slightly below like 2560*1440p 136hz. 120hz and below appears to fix the issue. DDU used with the latest nvidia drivers installed. I've got a vesa certified cable on order currently to see if that fixes it otherwise I'm guessing the monitor is faulty and there's no fix from what I've seen online? I'm currently on my second dp cable (neither probably vesa certified with first one being Dell original). Already done the basics like making sure cables are firmly in place, tried different gpu display port etc.
