Think my monitor is boinked

Recommended Posts

Samsung CFG70, 24", 144hz. The curved one

Connected via thunderbolt to displayport cable

Issue: When the monitor is set to 144hz, some of the top-row pixels exhibit a streaking effect. Issue occurs independent of refresh rate settings in windows. It does not occur of the monitor is set to 120hz or below

Steps taken to resolve: Tried a different computer, reset display settings. I don't have a different TB/DP cable to try, and the monitor only has a single display port in. Doesn't do it via an HDMI connection but HDMI doesn't support 144hz, where the issue occurs anyway. Opted not to mess with display drivers as it does the same on 2 different machines. However both display drivers were verified up to date

Any other ideas on what to try before I consider this a hardware failure?

Start with a new cable, it never hurts to have an extra one around.


Honestly it doesn't look like its the cable, could be anything from port on monitor to a bad connector in one of the cable ends, or complete hardware failure. I would try the cheap fix first.
