This problem usually occurs when users open the NVIDIA control panel but cannot apply the changes they have made in the program. This happens especially when you try to change things in the Manage 3D Settings section. It is also very present when you try to set the default GPU for a game on your computer.

There have been many different solutions to this problem over the years, and we have decided to gather the most useful ones and summarize them in this article. Follow these steps to solve the problem!

The Nvidia Control Panel is software that allows you to easily customize the hardware settings of your graphics card (GPU) and multimedia processor (MCP).

Before the company launched this product, users had to dive directly into their BIOS to configure their hardware settings. Frankly, it was a kind of pain.

All you have to do is open and optimize the control panel. You can assign different processors to specific programs, adjust your PC’s fan settings and customize your color profile for an optimal PC experience.

It is a software much appreciated by readers, video editors and other media professionals. But, it can be a little difficult to know if you don’t know what you’re doing.

Reinstalling the application

The first (and perhaps the most obvious) solution is to remove and reinstall the application. Whenever you have a problem with software, it is usually a must-have solution.

Essentially, you will only have to delete it from your hard disk and download a new version of the driver by following the steps described above.

  1. Disconnect your monitor from the power supply.
  2. Curiously, some users report that this is a monitoring problem.
  3. This makes perfect sense when you consider that Nvidia products are graphic material.
  4. You should therefore try to disconnect the monitor from the power supply and reconnect it.

This seems to be the solution for users who have several monitors connected at the same time. If you have more than one screen, disconnect the plug to the main screen and see if it works.
