Post-Login Freeze + Resolution Change Lag on with 1440p OLED

[OxidELareN]

Hello everyone,

I'm looking for help with a persistent issue on my system related to display freezing and severe lag when interacting with display settings.

Here is my setup:

• GPU: NVIDIA RTX 5070

• CPU: AMD Ryzen 7 5800X3D

• RAM: 32GB DDR4 3200Mhz

• Main monitor: ASUS ROG Strix OLED XG27AQDMG (1440p at 240Hz via DisplayPort, DSC turned off in OSD)

• Secondary monitor: ASUS TUF VG259QM (1080p at 240Hz via DisplayPort)

• Windows 11 Pro, build 22631 (23H2)

• NVIDIA drivers tested: 576.02, 576.28, 576.52

• Clean installs performed using DDU in Safe Mode for all driver changes

The core issue happens right after logging into Windows. Both monitors completely freeze for several seconds. The cursor is unresponsive, the desktop does not load, and the system feels entirely locked. After about 10–15 seconds (recently down to ~2 seconds), everything unfreezes and begins working normally — including games, applications, and general desktop usage. This only happens immediately after login. Safe Mode works flawlessly without any freezing.

In addition to the login freeze, I experience severe lag or full system freeze (up to 15–20 seconds) any time I:

• change the screen resolution or refresh rate via NVIDIA Control Panel or Display Settings

• switch display modes

• open Display settings or interact with monitor configuration in any way

This makes basic monitor setup tasks nearly unusable.

What I’ve tried so far:

• Clean DDU installs of the above-mentioned NVIDIA drivers (576.02, 576.28, 576.52)

• Disabling DSC in the monitor OSD

• Disabling HDR, G-Sync, VRR, Night Light

• Disabling HAGS

• Disabling MPO via registry

• Removing all ICC color profiles

• Disconnecting the secondary monitor for boot and login

• Updating monitor firmware to latest version

• Using CRU to remove fallback resolutions and extension blocks from both monitors

After deleting all ICC profiles and cleaning resolutions from the primary and secondary monitor using CRU, the post-login freeze has reduced to about 2 seconds, but it still happens every time on all Windows users. The display setting lag/freeze when changing resolution or refresh rate is still extremely bad, often locking up the entire system for nearly 20 seconds.

I have not yet tried using NVCleanstall for a minimal driver install, and I haven’t looked into Event Viewer or LatencyMon logs yet. I’d like to gather some feedback first.

Any help or insight would be greatly appreciated, if there are other people who might have experienced something similar. At this point, I’m trying to understand if this is a driver bug, a deeper Windows 11 + DWM issue, or something monitor-specific.

Thanks in advance.

Welcome to the forums!

Could be bad cables, but unlikely. Probably just another driver issue. NV drivers have been an UTTER mess since 50 series launch.
