Hardware Acceleration Overview
In some cases, once you discover that the windows 10 screen flickers or get into black screen suddenly, you need to consider something about hardware acceleration in Windows 7, 8 and 10. And if you are experiencing blurry or blurry videos or games in browsers, you’d better try disable hardware acceleration in Chrome, Firefox and Microsoft Edge .
And when seen in the screenshot below, hardware acceleration is set to complete , which means hardware acceleration is enabled by default. Thus, you should disable this feature to see if it works for flickering monitors or any other image or video related issues.
But most of you may have no idea what hardware acceleration does in Windows 10, not to mention how to disable it to solve hardware acceleration issues.
Here this post will show you how to disable hardware acceleration in Windows 7, 8, 10 to improve computer performance.
What is hardware acceleration?
For the sake of understanding, hardware acceleration is designed to send some tasks from the CPU to the GPU, thus relieving the load on the CPU. By doing so, the performance of the PC will be greatly improved as the CPU can process faster. That can be a way to make you watch videos smoother and more constant.
In detail, now people tend to just think of hardware acceleration as graphics acceleration as it often works for a graphics card or sometimes a sound card.
Of course, it’s best to leave hardware acceleration on for better graphics performance, but if there’s something wrong with your video card, for example, if the application cannot access graphics hardware you should try to disable Windows 10 hardware graphics acceleration immediately.
How to disable hardware acceleration in Windows 7, 8 and 10?
Depending on your Windows system, you are supposed to refer to different steps to disable hardware acceleration.
Normally, it is feasible to increase or decrease hardware acceleration in Windows 7, 8. While you can only choose to enable or disable it in older versions of Windows 10.
So, if you are determined to change the graphics performance, let’s start configuring the hardware acceleration. This post aims to close the hardware acceleration feature to fix various display issues.
Part 1: Disable hardware acceleration in Windows 7, 8
As suggested, in Windows 7 and 8, you can disable graphics acceleration by turning it to Neither or decrease its value.
If you have any graphics card bugs, aside from updating drivers, disabling hardware acceleration might also help.
1. Right click on the blank space on the desktop and then select Personalize in the context menu.
2 in Control panel display press Change display settings .
3. Click Advanced settings and then in To accept to continue .
4. in Solve problems choose change settings .
5. Then in the Display Adapter Troubleshooter , disable hardware acceleration windows 7 turning the slider to the left side where it is displayed Neither .
Here, as long as Hardware Acceleration is not grayed out and not available, if you want to reduce the hardware acceleration of Windows 7, 8, you should try moving left until a value suits you instead of None.
By the time you restarted your PC, you will have successfully disabled hardware acceleration in Windows 7, 8.
After that, in a broad sense, you won’t encounter any graphical errors, but if you still experience blurry or blurry videos or games in browsers, you’d better try disable hardware acceleration in Chrome, Firefox and Microsoft Edge .
Part 2: Disable Hardware Acceleration in Windows 10
Normally, you cannot increase or decrease hardware acceleration in Windows 10, what you can do is disable hardware acceleration.
And in normal cases, Windows 10 hardware acceleration is automatically turned on by default, but you can check it with the directx diagnostic tool .
1. Search dxdiag in the box to open the DirectX Diagnostic Tool.
2. In the directx diagnostic tool in the tab Screen you can see that hardware acceleration has been enabled.
As you can see above, DirectDraw, Direct3D and AGP Texture Acceleration are enabled. It implies that the hardware acceleration of Windows 10 has also been activated.
If you prefer hardware acceleration in Windows 10 disabled, just continue.
Here things get special with Windows 10 as it has been updated at intervals. In older versions of Windows 10, you can disable hardware acceleration as you like. But with Windows 10 updates, graphics card manufacturers have integrated hardware graphics acceleration feature.
In such cases, it makes sense to first check whether or not your graphics card supports hardware acceleration, as there is no such functionality in recent updates such as Windows 10 1803.
For earlier versions of Windows 10:
Go to Start > Setting > System > Screen > Advanced graphics settings > Display adapter properties .
Then you will see the display adapter properties like in windows 7. And you can try to do like Part 1 to disable Windows 10 hardware acceleration in the tab Solve problems .
For final versions of Windows 10:
Since you can’t find Windows 10 hardware acceleration as it is removed from system but built in your graphics card like NVIDIA, AMD, Intel graphics card. Therefore, you can navigate to the graphics card control panel to disable hardware acceleration.
For your reference, it will show you how to turn on Windows 10 graphics acceleration in NVIDIA Control Panel.
1. Right-click Desktop White Space, and then choose NVIDIA Control Panel of the list.
2 in NVIDIA Control Panel go to 3d settings > Set Surround , PhysX and then set the CPUs As the processor in instead of automatically selecting or NVIDIA GeForce GTX 750 Ti.
That will allow the CPU to run tasks and disable NVIDIA acceleration in Windows 10.
Similarly, you can make use of the same way to configure hardware acceleration settings for AMD, Intel HD graphics cards.
Here, if you want to disable graphics acceleration to fix video card issues, you can also update nvidia driver Intel or AMD for Windows 10.
However, according to many users, in the process of turning off Windows 10, 8, 7 hardware graphics acceleration, you have come across hardware acceleration grayed out, which makes you not turn off this option.
So if you are unable to remove hardware acceleration in Windows 10, then go ahead to end it in Registry Editor.
How to fix hardware acceleration grayed out in Windows 10?
Either there is no hardware acceleration in Windows 10 1803 and later or hardware acceleration is not available in Windows 7, 8, you can simply turn to Registry Editor to disable it.
Even if the DisableHWAcceleration value does not exist in the registry, you can also add one and disable Windows 10 hardware accelerator.
But before doing so, you should back up your records in case of data loss, so you are suggested to try this way at the final place.
1. Press Windows + R and then enter regedit in the frame.
2 in Registry Editor navigate to HKEY_CURRENT_USER SOFTWARE Microsoft Graphics .
3. in Avalon.Graphics in the right pane, check if there is a key called DisableHWAcceleration .
If there isn’t, on the right side, right-click on the blank space to create a new value DW0RD (32 bits) and assign him the Name DisableHWAcceleration .
4. Right click on the recently added value DisableHWAcceleration for modify it .
5. Change DisableHWAcceleraion from to 1 to disable Windows 10 hardware acceleration.
Restart Windows 10 and then you will see the flickering or black screen disappeared due to disabled hardware acceleration.
In this way, you can not only solve hardware acceleration problem in Windows 10, but also disable graphics acceleration from the registry editor.
In short, with the help of this tutorial, you can master the methods to disable hardware acceleration in Windows 7, 8 and 10. And even if it is not available, you can also ask the registry editor for help.
