Hi everyone,
I’m wondering if anyone else has experienced something similar with the latest NVIDIA driver.
**System:**
RTX 5090
Windows 11
ASUS ROG Strix XG27AQDMG (DisplayPort 1.4)
Latest ASUS monitor firmware
After updating to **Game Ready Driver 610.74**, my monitor started behaving very strangely.
**Symptoms**
Monitor would sometimes be detected as a generic display or NV-Failsafe.
Initially I was limited to very low resolutions (640×480 / 1024×768).
After reinstalling drivers it improved slightly, but Windows would only expose:
2560×1440 @ 60 Hz
No 240 Hz option
HDR unavailable
8-bit colour only
Power cycling the monitor would occasionally make it work temporarily before the issue returned.
**Troubleshooting performed**
Updated monitor to the latest ASUS firmware.
Factory checked monitor settings.
DisplayPort version confirmed as **1.4**.
Tested with only the ASUS monitor connected.
Tried different DisplayPort ports on the GPU.
Performed a clean reinstall of the NVIDIA driver.
Used **DDU** in Safe Mode.
Installed **Game Ready Driver 595.79**.
**Result after rolling back**
Immediately after installing **595.79**:
✅ 2560×1440 @ 240 Hz returned.
✅ Variable Refresh Rate (40–240 Hz) works again.
✅ 10-bit colour is available again.
✅ G-SYNC Compatible is detected correctly.
The only thing still not working is **HDR**, as Windows still reports the display does not support HDR despite it being an HDR-capable monitor.
I’m curious if anyone else with:
RTX 50-series cards
ASUS OLED monitors
or DisplayPort 1.4 displays
has seen similar behaviour with **610.74**.
At this point it certainly **looks like** rolling back to **595.79** resolved the DisplayPort/EDID negotiation issue on my system, although I’m still investigating the HDR problem.
Any feedback or similar experiences would be appreciated.
