The AIO PC gets these color lines. It has NVidia RTX 4050, i updated the drivers but its still the same. I dont see them via LMI. Any ideas?

Is the monitor plugged in into GPU or motherboard? 🤔 ~ Reseating cables(might be lose or damaged), or changing cable

Tech A 2025-02-06 14:15

im sure its plugged in properly, since its AIO 🙂

You can try removing the driver from devices manager, reboot and clean setup from nvidia

Tech A 2025-02-06 14:20

Okay, I'll try that, thanks

Tech C 2025-02-06 14:28

are those lines visible at all times? or just inside the OS? what about when its booting up o.o? the screen might just be cooked 🫠

Tech A 2025-02-06 14:35

afaik, its only visible on the dark bg

Tech A 2025-02-06 14:35

Tech A 2025-02-06 14:36

Tech A 2025-02-06 14:37

i might have to just go ther and check myself...

Tech D 2025-02-06 14:40

Some AIOs have a built-in self-test, if you hold the power button for example.. maybe you can test the screen there?

Tech A 2025-02-06 14:41

test anything with Dr H? YOu have to be kidding me 🙂

Tech D 2025-02-06 14:41

Better to ask him to buy a new one if it's Dr. H

Tech D 2025-02-06 14:41

Went to the onscreen menu and did factory reset. After that it went back to normal.

# Fix vertical line artifacts on Lenovo ThinkCentre AIO display

## Problem
A newly installed Lenovo ThinkCentre all-in-one PC with NVIDIA RTX 4050 displayed prominent vertical line artifacts across the entire screen. The lines were visible on dark backgrounds and during the Windows login screen, but were not visible when accessing the machine remotely via LogMeIn. The issue persisted after updating GPU drivers. A second identical model from the same batch did not exhibit this problem.

## Resolution
1. Access the monitor's onscreen display (OSD) menu
2. Navigate to factory reset option
3. Execute the factory reset
4. The display artifacts should be resolved after the reset completes

Note: Updating GPU drivers and reseating display cables did not resolve the issue in this case.
