nvidia panel access denied. Tuning NVIDIA for maximum gaming performance. NVIDIA Control Panel does not open - symptoms and causes

A huge variety of owners graphic cards from NVIDIA suffer from the same misfortune - the inability to open the Nvidia Control Panel. This problem was noticed on all versions operating system Windows, from Windows 7 to Windows 10. All attempts to open the Nvidia Control Panel through the Start menu proved to be completely useless.

In this article, we will look at the problem of the inability to open the Nvidia Control Panel. We will try to update and reinstall the latest drivers for the video card from the official website. We will also try to deal with the NVIDIA Display Driver service, update the .NET Framework libraries, restart the Nvidia Control Panel process, and much more.

First of all, you should try reinstalling the Nvidia drivers. To do this, do the following:

Click Windows+R and enter devmgmt.msc.
With Device Manager open, find the “Display Adapters” drop-down tab and open it.
Right-click on your graphics accelerator and select “Uninstall.” Confirm your intentions by checking the box next to “Remove driver programs for this device” and clicking OK.
Then go to the official Nvidia website to download the drivers needed for your video card.
The note: We do not recommend that you choose automatic search drivers, as this sometimes leads to various failures, and it can also take a huge amount of time. It will be better if you use manual selection of drivers.
After downloading the driver package from Nvidia's website, run the installer to begin the driver installation process. We have already removed the drivers for the video card through Device Manager, but it will still be better if you check the “Clean installation” option during installation.
After installing the new drivers, restart your computer and then try accessing the Nvidia Control Panel again.
The note: alternative installation Drivers can be Device Manager, with the help of which you can also do this. However, under certain circumstances, various problems may arise. However, if you want to install drivers this way, then do the following:
- Click Windows+R and enter devmgmt.msc.
- Once you open Device Manager, find the “Display Adapters” drop-down tab and open it.
- Right-click on your video card and select “Update Driver...”, after which Device Manager will install everything itself.

Method #2 Setting up the NVIDIA Display Driver service

The NVIDIA Display Driver service is responsible for launching the Nvidia Control Panel. Accordingly, if this software stopped responding, then restarting the service that depends on it is a completely reasonable solution.

Click Windows+R, enter services.msc and press Enter.
Look for a service called "NVIDIA Display Driver Service" in the list.
Click on it twice to go to its Properties.
Find the Startup Type drop-down menu and click on it.
Select the "Automatic" option.
Then make sure the service is running. If not, then click on the “Run” button.
Repeat the same steps for all Nvidia services that will run on your computer.
After completing these steps, try launching Nvidia Control Panel again.

The note: Even if it indicates that Nvidia services are running, it is still better if you restart them manually. To do this, click “Stop→Run” and do this with each Nvidia service.

Method #3 Restarting the Nvidia Control Panel process

This method is quite similar to the previous one. When you launch Nvidia Control Panel, the process may start to malfunction. In this case, you just need to restart the process.

Press the key combination Ctrl + Shift + Esc to open Task Manager.
Go to the tab with open processes.
Find the process called nviplui.exe right-click on it and select “End process”.
Also try closing other processes that are related to Nvidia.
Now that all processes have been closed, try opening the Nvidia Control Panel again.

If the problem was a process that was malfunctioning, then such a simple restart will help correct the situation.

Method No. 4 Setting a higher resolution

Some users on the network were able to overcome the problem with the Nvidia Control Panel not starting using a rather strange solution - setting a higher resolution. Again, some users claim that it may not launch due to the low resolution.

Right-click on the Desktop and select "Screen Resolution".
Click the Resolution drop-down menu and select the highest possible resolution for your monitor.
Apply the resolution changes.

With the resolution set higher, try launching the Nvidia Control Panel. If it starts, then the problem should be resolved and you can set your standard resolution.

Method #5 Fixing the Windows Registry

If you were still unable to resolve the problem when launching the Nvidia Control Panel, now we will try to fix the entries in Windows Registry. As always, be careful when changing entries. We recommend that you create backup copy your Windows Registry so that if something unexpected happens, you can quickly recover.

Click Windows+R, enter regedit and press Enter.
Walk the path HKEY_CLASSES_ROOT\Directory\Background\ContextMenuHandler.
Find NvCplDesktopContext, right-click on it and select “Delete”.
Now go to HKEY_CLASSES_ROOT\Directory\Background\shell.
Right click on Shell and select “New→Partition” and name it Nvidia Control Panel.
Right click on Nvidia Control Panel and select “New→Partition”. Name this section command.
Double click on command and enter the value in the line C:\Windows\System32\nvcplui.exe, and then click OK.
Exit the Windows Registry and restart your computer.

After making small changes to your Windows Registry, try opening the Nvidia Control Panel again. She should definitely open up calmly this time.

Method #6 Updating the .NET Framework and VC++ Redistributable

NVIDIA applications, as expected, run on software such as the .NET Framework and VC++ Redistributable. If you have installed on your computer outdated versions these libraries, then the inability to open the Nvidia Control Panel may be an expected problem.

Try updating the .NET Framework and VC++ Redistributable by downloading from the download section of the official Microsoft website. In addition, you can also check if you have any pending updates for the operating system. Try installing them if available.

Method #7 Disabling Quick Boot

UEFI based firmwares have the function quick launch, which helps your computer start up faster. However, this function has one drawback - because of it, some third party application, drivers and services simply cannot start simultaneously with the system, i.e. their launch is skipped.

If you have it enabled this function and you cannot launch the Nvidia Control Panel, then the above event may have occurred. You need to go to your BIOS settings and disable Quick Boot or Quick Startup.

The guide describes in detail the process of managing NVIDIA video card settings. We will also tell you how to configure NVIDIA 3D settings for some games. Before setting up, you need to install drivers for Nvidia.

If the drivers are installed, we begin configuration.

Click on the desktop right click mouse to display a pop-up menu. In which we select the item:

After this we get to the control panel. Let's go to the section: 3D Options

In the window that appears, first select the item: Adjusting Picture Settings with Preview

Click: Apply(as shown in the picture below)

Now the fun begins.

Configuring NVIDIA 3D Settings for Games

Let's go to the section: Managing 3D Settings

After this, we proceed to configure the parameters in the right window.

For the applications to work correctly, you must set the following parameters:

CUDA- GPUs: All
Anisotropic filtering: Turn off
V-Sync (Vertical Sync): Turn off
Vertical sync pulse": Use 3D Application Setting
Background lighting shading": Turn off
Maximum number of pre-prepared frames: you should select the item marked with the NVIDIA icon

Anisotropic filtering. Directly affects the quality of textures in games. Therefore it is recommended switch off.
Enable scalable textures: Turn off
Expansion limitation: Turn off

Depending on the driver version and video card, some parameters may not be available in the settings.

After changing all the settings, click the Apply button. These settings do not guarantee 100% results, but in 90% of cases they can increase FPS by up to 30%.

Which cannot be changed using Windows settings. In particular, you can use it to change the resolution, adjust the brightness and saturation of the image, rotate the screen, configure 3D graphics and much more. In this article we will talk about how to open the NVIDIA Control Panel and what to do if it does not open.

Method number 1. Context menu on the desktop.

The easiest way to open the NVIDIA Control Panel is to use the context menu on your desktop. To do this, you just need to right-click on an empty space on the desktop and select “NVIDIA Control Panel” from the menu that appears.

Method number 2. Control panel.

If you are unable to open the NVIDIA Control Panel using context menu on the desktop, you can use an alternative method. To do this (in Windows 10 it is convenient to use the Windows + X key combination) and then go to the “Hardware and Sound” section.

After this, you need to scroll to the very bottom of the window and click on “NVIDIA Control Panel”.

NVIDIA Control Panel won't open?

Sometimes users encounter the problem that the NVIDIA Control Panel does not open on their computer. This usually indicates problems with the drivers. In this case, it is best to completely install them again.

In order to completely remove NVIDIA drivers Download and install Display Driver Uninstaller from your computer. After that, restart your computer and run this program. After that, open the drop-down menu and select “NVIDIA” there. This way you will tell the Display Driver Uninstaller program that you want to remove the drivers specifically for the NVIDIA video card.

After reboot, go to normal mode Windows operation, install new drivers and reboot the computer again. In most cases, this procedure will be enough for the NVIDIA Control Panel to start opening normally.

Sometimes, when trying to access display settings on computers with NVIDIA graphics adapters installed, the user may receive a message stating that NVIDIA display settings are not available. It's impossible to change anything at all. What to do in such a situation, read the material below.

NVIDIA Control Panel: NVIDIA Display settings are not available. What is the reason?

Most experts cite problems with video card drivers as the reason for this situation. It is not surprising, since it is precisely this control software that ensures the connection of the graphics adapter with a computer monitor or laptop screen.

But why NVIDIA display settings are not available in each specific case can sometimes be quite difficult to determine, despite the known root cause. Drivers may be out of date, missing, or even corrupted. Depending on this, you can apply several effective solutions that will help eliminate the problem. The methods are quite simple, but in some cases it is necessary to take into account the specifics of the situation.

What should I do if my NVIDIA display settings are unavailable?

Let's start with the simplest. If a similar message appeared at one “wonderful” moment when the system started, but everything worked before, perhaps this is somehow connected with failures in the OS itself. There is nothing easier than activating system recovery to the state when the problem did not exist.

The same applies to the situation when a notification appears that NVIDIA display settings are not available in Windows 10 or any other OS version after installing updates. It is quite possible that some of them were installed incorrectly or themselves cause problems with the operating system. In this case, in the programs and components section, you need to remove recently installed updates, sorting them by installation date. But you need to remove them one by one, rebooting the system and trying to access the settings. When a faulty update is found, you should set up a manual search, and then exclude the faulty package from the list, having first remembered or written down its number.

Another completely banal reason is associated with situations when two video cards are installed on the computer (discrete and integrated). You can correct the situation in the “Task Manager”, where the built-in adapter is disabled if it is used in this moment, or the NVIDIA card is activated.

Exactly the same actions for cases where the “Device Manager” settings have no effect can be performed in BIOS settings, where NVIDIA is selected from the list of installed video cards.

Reinstalling and updating drivers

But, suppose that all the above methods did not work, and the system again displays a message that the NVIDIA display settings are unavailable. In such a situation, manual user intervention will be required.

To avoid going too far, try updating the adapter drivers in the same Device Manager. If this doesn't work, remove the drivers or even the video card itself. It is possible that the drivers will be installed automatically upon reboot. As a last resort you can use installation disk with adapter drivers, if available. But the biggest problem is that drivers are not always removed this way, and the message that NVIDIA display settings are not available appears again and again.

Removing old drivers

In this case, you will need to uninstall all drivers and related software yourself, using the programs and components section located in the Control Panel.

Also for complete cleaning system from unnecessary drivers, you can use the Display Driver Uninstaller utility (but it is intended only for drivers and does not remove additional programs).

After this, you should reboot the system and install all components again. To install the drivers most latest versions It is best to use automated utilities like Driver Booster, which will update the control software for absolutely all devices on the computer.

Specialized drivers

Another option to fix the problem of NVIDIA display settings being unavailable applies to non-standard laptop models.

First, call the “Run” menu and enter the msinfo32 command, then find the exact name of the laptop model. Then go to the manufacturer's official resource, search for drivers by model name and download the appropriate driver, then install it yourself.

Note: if the installer is presented as an EXE file, use normal run as administrator. If this INF file, through RMB, select the “Install” line. If the system reports that the driver cannot be installed this way, go to Device Manager, select driver update, and specify the path to the saved INF file.

Some manufacturers offer users an online laptop check, after which they will be given a list of problems, as well as tips on how to fix them. And you don’t have to download the graphics adapter driver, but install it directly from the manufacturer’s website.

Afterword

That's all that can be said about eliminating the problem described above. Which product should I use? The question is rhetorical. In principle, you can immediately install an automated driver update program. If the problem is not with the drivers, but with additional software, you will have to get rid of it and then install it again by downloading latest version from the NVIDIA website. However, those who have skills in working with drivers can perform all the steps manually.
