Question Blue vertical lines on monitor

[TylerWalsh1998]

Hello,

My 144hz gaming monitor has recently started showing blue lines on the display (imgur link with photo) when in windows. It does not happen with my other second monitor which is 60 hz. When I go into windows display settings and set the 144hz monitor back down to 60hz, these lines go away.

If someone has any advice on how to fix this, that would be great.

Update to this post, I have tried a different display port cable on the monitor and it still does the blue lines when set to 144 hz in windows. When set to 60 hz it is fine. When I use a HDMI cable and set it to 120 hz, it does not due the blue lines. Any help would be appreciated thanks

When I go into NVIDIA Control panel and change from 120 hz back to 144 hz in there, the lines go away
