I am not working with 4K however I am getting the same thing. Chatted with nVidia and they gave me this info below. so far I have no issues. I am using a Quadro 4000 and editing 1080p with Premiere:
Try "Display Driver Uninstaller (DDU) " to completely uninstall NVIDIA / AMD graphics card drivers and packages from your system, without leaving leftovers behind (including registry keys,
folders and files, driver store) :
After the download is completed, it would prompt you to extract the file. Once the display driver uninstaller is extracted under download folder you would see Display driver uninstaller .exe file. Double click on it to proceed with the installation. After the Display driver is installed, it would prompt for system restore point creation and booting the computer in safemode.
Once done, - Select NVIDIA on top and Put a check mark on all the NVIDIA components near the NVIDIA logo.
- Now click on Clean and Restart (Highly Recommended)
- Once the computer restarts and goes to the Windows, please follow the steps below
Shut down the computer remove the graphics card and reseat is after 60 seconds turn on the computer download and install the below drivers after the card is detected.
