Displaying issues at 4K resolution
Displaying issues at 4K resolution
Hi all, I’m facing some issues and feeling quite frustrated. My computer specs are attached as well, which you can see below. I have an ASUS HERO Z790 Maxmimus I9 13900k (13th gen) paired with a Gigabyte RTX 4080, swapped to an ASUS ROG RTX 4090. The setup includes four Corsair Vengeance 16GB 5600MHz cards with XMP enabled and a 1500W PSU. The monitor is an Asus ROG XG32UQ, and the BIOS is up to date. The problem isn’t happening at 2K resolution, but it still occurs. HDR mode works, yet turning it off doesn’t resolve it. Hardware acceleration isn’t helping either.
The main difficulty appears in games with heavy physics—like Rocket League, Warframe, and DayZ. I encountered an issue with Diablo 4, where I received an NVDDM error that caused the game to crash and freeze the screen. This seems to be a common concern for RTX gamers; I’m not sure if it’s related.
We tried adjusting framerates, toggling V-sync and G-sync, and disabling ASUS multicore enhancement and Intel Turbo Boost in the BIOS, but nothing worked. Any advice would be greatly appreciated!
Update: It turns out the RTX 4080 was underpowered—only two PCI/e cables were connected instead of three with the included splitter. Could this have been the cause? I switched to a card with three PCI/e cables and three cables going to the PSU.
Solution: I purchased a new RTX 4090 and installed it in my PC. My usual Discord friend was there during testing, but he ended up going home when stuttering started. We tried setting the priority to below normal, which stopped the issue. We disabled hardware acceleration and checked for problems, but nothing resolved it. He also found a video about adjusting DPI settings.
The 4K resolution seems problematic with Discord. Here’s what we did:
- Press Windows key + R, type 'discord' and press Enter.
- Right-click the Discord icon and choose ‘Go to file location’.
- Right-click the Discord shortcut and select ‘Properties’.
- Go to the ‘Compatibility’ tab and click ‘Change high DPI settings’.
- Select ‘Use this setting to fix scaling problems for this program instead of the one in Settings’.
- In the dropdown, choose ‘Use the DPI that’s set for my main display when’.
- Then select ‘I open this program’.
It looks like Discord might struggle with handling two monitors and their resolutions. I’m relieved we found a workaround, though it took me about two weeks of troubleshooting. Hopefully, this helps others facing similar challenges.

Download Hwinfo64 and select only sensor data when launching the app. Operate your games. Verify the RAM spike isn't occurring. Monitor CPU temperatures and see if throttling happens.
Thanks for your reply! I installed Hwinfo64 and had a friend verify the data while I played some games. He created an alert for any unusual activity and kept an eye on it for about 20 minutes. We even ran a benchmark in the background, but it didn’t increase the micro stutter much. There’s no thermal throttle, though locating a RAM throttle with Hwinfo64 was tricky. CPU-Z looks clearer, so we’ll try again soon.
We checked CPU-Z but it didn’t display specific RAM module details. I’m looking for tools that can show the clock speed of each RAM stick separately.
This ensures we rule out a bad RAM stick. It's strange how certain titles like Warframe, Dayz, and Rocket League often freeze while others such as Diablo 4 or Cycle Frontier run smoothly.
If the monitor is losing frames, they may appear similar to a stutter. You can mimic the same stress by using a 1080p screen and reducing the resolution to 4K. In the Nvidia Control Panel → 3D-settings → Manage 3D-settings, look for "DSR - Factors" in the options. Select the 4.00x setting so the system can render 4K on the lower-resolution display, which will then downscale it to fit. You may also adjust the DSR - Smoothness slider; lowering it makes the screen look smoother, like a varnish coating, though this is mainly for testing purposes. Finally, switch the monitor’s resolution to 4K.
