Samsung CHG90 49 Ultrawide 144Hz - Works after warm-up

Model: LC49HG90DMUXEN Resolution: 3840x1080 (32:9 ultrawide) Refresh Rate: 144HzAge: ~5 years When you first turn this monitor on, it displays visual artifacts (thin stripes/pattern) for approximately 3-5 minutes. Once it warms up, the artifacts disappear completely and it works perfectly. I used it for coding for 2 months with this issue - just turned it on when I started my morning routine, and by the time I sat down to work, it was fine. No issues during use once warmed up. What causes it: Likely a cold solder joint or capacitor issue. The monitor menu itself shows the same artifacts, so it’s the display hardware, not the signal. It may worsen over time - I can’t guarantee how long it will continue working. Why I’m selling: Upgraded to higher resolution. This worked fine for my needs, but I wanted more vertical pixels. Good for: • Gaming (144Hz is solid) • Secondary workstation • Someone who can repair it • Anyone who doesn’t mind the 5-minute warm-up quirk Price reflects the defect. Collection only. Photos show both startup artifacts and normal operation.​​​​​​​​​​​​​​​​
