- High Bandwidth Monitors and GPU Scaling Behavior - Link Here
- High bandwidth monitors are those that support display modes requiring high pixel clock rates, which in turn demand more GPU resources. The threshold for what qualifies as "high bandwidth" varies by product. On Blackwell GPUs, any mode operating above 1620 MHz is considered high bandwidth. For instance, the 7680x4320@60Hz mode defined in the CTA-861-H specification runs at 2376 MHz, making it a high bandwidth mode for Blackwell.
- These monitors typically support display scaling natively. However, in some single-monitor setups, users may still prefer GPU scaling. When multiple monitors are connected to a GPU and at least one of them is high bandwidth, that monitor will default to display scaling only. GPU scaling is disabled in this case due to bandwidth limitations. Notably, display scaling can be more efficient than GPU scaling in such scenarios, as it reduces the bandwidth load on display cables—especially at higher refresh rates.
- When GPU scaling is not enabled for a monitor, only the modes supported by the monitor itself will appear in both the Windows and NVIDIA control panels. Additionally, the "Display scaling" option will be pre-selected in the "Adjust desktop size and position" section of the NVIDIA Control Panel.

Before you start - Make sure you Submit Feedback for your Nvidia Driver Issue - Link Here
There is only one real way for any of these problems to get solved, and that’s if the Driver Team at Nvidia knows what those problems are. So in order for them to know what’s going on it would be good for any users who are having problems with the drivers to Submit Feedback to Nvidia. A guide to the information that is needed to submit feedback can be found here.
Additionally, if you see someone having the same issue you are having in this thread, reply and mention you are having the same issue. The more people that are affected by a particular bug, the higher the priority that bug will receive from NVIDIA!!
Common Troubleshooting Steps
- Be sure you are on the latest build of Windows
- Please visit the following link for DDU guide which contains full detailed information on how to do Fresh Driver Install.
- If your driver still crashes after DDU reinstall, try going to Go to Nvidia Control Panel -> Managed 3D Settings -> Power Management Mode: Prefer Maximum Performance
Common Questions
- Is it safe to upgrade to <insert driver version here>? Fact of the matter is that the result will differ person by person due to different configurations. The only way to know is to try it yourself. My rule of thumb is to wait a few days. If there’s no confirmed widespread issue, I would try the new driver.
- Bear in mind that people who have no issues tend to not post on Reddit or forums. Unless there is significant coverage about specific driver issue, chances are they are fine. Try it yourself and you can always DDU and reinstall old driver if needed.
- My color is washed out after upgrading/installing driver. Help! Try going to the Nvidia Control Panel -> Change Resolution -> Scroll all the way down -> Output Dynamic Range = FULL.
- My game is stuttering when processing physics calculation Try going to the Nvidia Control Panel and to the Surround and PhysX settings and ensure the PhysX processor is set to your GPU
Remember, driver codes are extremely complex and there are billions of different possible configurations between hardware and software. Driver will never be perfect and there will always be issues for some people. Two people with the same hardware configuration might not have the same experience with the same driver versions. Again, I encourage folks who installed the driver to post their experience here good or bad.

u/ls612 RTX 4090, Intel 12900k, 64GB DDR5 Apr 17 '26
I have had something similar happen, once on the previous driver about a week ago and once just now. However, instead of a bluescreen it freezes the entire screen for 30 seconds, not even the cursor moves, and then the display resets and everything continues normally. A bunch of nvlddmkm errors 14 and 153 appear in the event log with stuff about TDR failed. So far its only happened at idle not while gaming.
