Hi all,

Randomly, overnight, it's like my multi-monitor display suddenly stopped working. Here is an unlisted video showing the issue. It's like one monitor, specifically, through DisplayPort is no longer even being recognized. Tried switching the cables to no avail. Haven't tried HDMI. But an image pops up, and the little orange light in the corner will momentarily turn blue as if it's receiving a signal. Then it goes back to orange. It looks like NVIDIA sees it, but when I press the check box (see video above), there's a strange hitching that happens.

Everything was fine last night. Woke up this morning and poof, nothing.

Tried doing a safe boot with DDU and reinstalling my latest drivers. No luck. Maybe a recent Windows 10 or NVidia driver incompatibility?

My build is as follows:

CPU: i9-10900k
GPU: RTX 3070
RAM: 128GB
MOBO: Z490-E

Thank you in advance! Looking forward to any input.

Tried HDMI. Seems to work, but it locks it to 60hz on that one monitor due to the HDMI.

This is frustrating. Could it be a DisplayPort issue on the monitor itself?
