Within the last two weeks the image on my CG437KP has started to "jump", or shift the frames up slightly, every 3 seconds or so. The problem gets worse if I change the refresh rate of the monitor in which case, I get a larger shift upward and the frames overlap even more and for slightly longer periods. I have two Windows 10 PCs attached to the monitor on the DP ports - a desktop with Nvidia cards (and gsync) and an old Dell laptop with an Intel GPU. At first, I was only seeing the issue with the laptop and when I switched the refresh rate to 30hz on that it went away for a few days, so I thought it was the laptop GPU. Now it's happening persistently for both PCs and as of today, not even rebooting the PCs or powering on/off the monitor has resolved the issue for long. I have the latest drivers for both systems and I have reinstalled the drivers on both. Actually, today there was an Nvidia driver update and that also didn't fix it. The problem has gotten progressively worse in the two weeks since I first noticed it, in that its now happening for both PCs, on both the DP and the USB-C input port and it isn't resolved by rebooting, unplugging the monitor, changing the screen size or refresh rate, etc.
Does anyone have suggestions for what the issue might be? Or is it the hardware and I need a support ticket?
