Ongoing Display Issues with Arc A750 – Flickering, Input Lag & Strange Line at 165Hz

[Zayed1]

Hey Intel team,

I’ve been dealing with some really frustrating display issues on my Arc A750, and after trying just about everything, I’m hoping someone can shed some light or help troubleshoot further.

My setup:

GPU: Intel Arc A750

Monitor: MSI G243 (165Hz, DisplayPort)

Cable: DisplayPort 1.4 certified

Driver: Latest Arc graphics driver

What’s happening:
1. At lower refresh rates like 60Hz or 75Hz, the screen flickers badly.

2. At 165Hz, flickering stops — but there’s always a thin horizontal line at the top of the display.

3. I'm also noticing input lag and sluggishness even when running at 165Hz.

4. The flickering even shows up during reboots or when changing refresh rates in Windows.

What I’ve tried so far:
1. Initially did a normal driver install, issue appeared right away.

2. Used DDU to fully clean and reinstall drivers, but the issue still persists.

3. Disabled Adaptive Sync, V-Sync, Overdrive, and every variable refresh option — no change.

4. Tried multiple DisplayPort cables, all certified, and even had the monitor and GPU checked — no hardware faults.

5. Reset monitor settings to factory defaults, still the same.

This never happened on my previous GPU driver but when I used to a previous driver, same issue arose, so I’m pretty confident it’s something driver- or firmware-related with Arc. I really want to keep using this card — performance is solid, and I love what Intel’s doing here — but this issue is affecting day-to-day usability.

If you need any logs, system info, or screen recordings, I’m more than happy to help.

Thanks in advance!
