有时，据报道，显示器显示失真，图像出现水平线条呈波浪状，视频显示帧位置不正确。发生这种情况的原因是显示器刷新率错误，显示驱动程序无法将帧正确地放在屏幕上。然后是称为工件的硬件限制问题。我们已经了解了如何 解决屏幕撕裂问题(fix Screen Tearing issues)，现在让我们看看在Windows 11/10失真(Distortion)问题的各种方法。
什么是撕裂/扭曲/水平线/伪影？
撕裂是一种视频伪影，其中一系列水平线(horizontal lines)似乎在屏幕上移动，从而产生撕裂（撕裂）效果。
它们在动画期间更加明显(more noticeable during animations)，例如当您在屏幕上移动窗口时。或者当您进行屏幕录制时。或者当你在玩游戏时。
当您有两台显示器时，这会增加，并且刷新率之间存在很大差异。(difference between the refresh rate.)该问题可能仅出现在其中一台显示器上。
屏幕上的撕裂或伪影也是由不良的视频驱动程序(poor video driver)或显示器上的绘图与发送到图形驱动程序的数据之间的同步问题引起的。(sync issue)
显示伪影或失真的PC屏幕(Screen)
您可以按照这些建议在显示器上解决此问题。
- 在Windows中启用硬件加速(Hardware Acceleration)
- 在 Windows 中更新图形驱动程序
- 远程桌面问题
- 附近磁场
- 将 GPU 设置重置为默认值
对于某些方法，您需要 Windows 11/10 PC 上的管理员帐户。
1]在Windows中(Windows)启用硬件加速(Enable Hardware Acceleration)
启用硬件加速(hardware acceleration)有助于修复屏幕上的失真和伪影。要解决此问题，请执行以下步骤：
- 打开 Windows 10 设置
- 导航到系统 > 显示
- 单击图形设置链接
- 打开“硬件加速GPU调度”选项
重新启动计算机，并检查问题。

2]在Windows中(Windows)更新(Update) 图形(Graphics) 驱动程序(Driver)
检查您的显卡驱动程序是否有更新(update for your Graphics Driver)。你可以通过两种方式做到这一点。第一个是在 OEM 网站上查看(checking on the OEM website)，第二个是通过可选的 Windows 更新(Optional Windows Update)。
转到Windows 10 Settings > Update and Security > View Optional Update（在更新按钮下）。查找是否有可用的驱动程序更新。即使您通过设备(Device)管理器进行检查，屏幕也会将您带到这里。如果有更新，请选中该框并更新。
请注意，它可能并不总是显卡问题(may not always be a graphics card issue)，并且在玩游戏时一切正常并且没有任何失真。只有在使用文件资源管理器(File Explorer)、图像、桌面壁纸时才会注意到它；光标可能会消失，图像和文本可能会显得模糊。您还可以观察到粉紫色的色调(observe a pink-purple tint)。

3]远程桌面问题
一些用户报告说，当他们使用远程桌面连接到另一台 PC(connect to another PC using a remote desktop)时，会出现这些线路和补丁。在这种情况下，您可以启用硬件加速。
- 通过在运行(Run)提示符 ( Win + R ) 中键入gpedit.msc打开组策略编辑器，然后按Enter键。
- 导航到以下路径
Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Connection Client。
- 找到并打开策略 -不允许硬件加速解码(Do not allow hardware-accelerated decoding)。请设置为启用。
此策略设置指定如果支持的硬件可用，远程桌面连接是否可以使用硬件加速。(Remote Desktop Connection)
如果启用此功能，远程桌面连接(Remote Desktop Connection)软件将仅使用软件解码。启用或未配置后，如果支持的硬件可用，(use hardware-accelerated decoding if supported hardware is available.)远程桌面(Remote Desktop)客户端将使用硬件加速解码。
如果它已启用或未配置，您可以禁用它并检查问题是否已解决。硬件(Hardware)加速可能有帮助，也可能没有帮助，但切换设置有助于了解这是否有影响。重新连接到远程桌面，并检查您是否遇到同样的问题。

4]附近的磁场
众所周知，磁铁会导致显示屏失真，并且据观察，扬声器产生的磁场也会使图像失真。扬声器可能正在产生磁场。
找出显示器周围的设备，并检查其中是否有磁铁或电磁铁。扬声器通常位于显示器的两侧。关闭它们，并检查问题是否仍然存在。

5]将GPU设置重置为默认值(Reset GPU settings to default)
大多数OEM(OEMs)提供的GPU软件允许您将设置重新配置为默认设置，并为您的 GPU 和显示器提供最佳设置。(reconfigure the settings to default, with the optimal setting for your GPU and display.)您可以从 OEM 的支持网站下载最新的GPU软件。(GPU)安装后，打开并应用默认或平衡设置。
我希望这篇文章很容易理解，并且您能够解决 PC 屏幕显示伪影或失真的问题。如果对您没有任何帮助，是时候联系硬件(Hardware)支持团队并寻求帮助了。如果没有任何帮助，您可能必须退回硬件或笔记本电脑进行维修。

Screen or images showing Artifacts or Distortion in Windows 11/10
At times it has been reported that the monitоr displays distortion, images appear wavy with horizontal lineѕ, аnd videos showing frаmes аt incorrect positions. It happens because of the wrong monitor refresh ratе where the display driver іs not able to put the frames on the screen prоperly. Τhen there are hardware limitation issues knоwn as artifacts. We have already seen how to fix Screen Tearing issues, now let us look at the various methods to fix thisArtifacts or Distortion problem on Windows 11/10.
What are Tearing/Distortion/Horizontal Lines/Artifacts?
Tearing is a video artifact in which a series of horizontal lines appear to be move across the screen, thus creating a tearing (tearing apart) effect.
They are more noticeable during animations, such as when you are moving a window around on your screen. Or when you are doing a screen recording. Or when you are playing a game.
This adds on when you have two monitors, and there is a substantial difference between the refresh rate. It is possible the issue may occur only on one of the monitors.
Tearing or artifacts in the screen are also caused by a poor video driver or a sync issue between drawing on the monitor and data sent to the graphics driver.
PC Screen showing Artifacts or Distortion
You can follow these suggestions to fix this issue on your monitor.
- Enable Hardware Acceleration in Windows
- Update Graphics Driver in Windows
- Remote Desktop Issue
- Nearby magnetic field
- Reset GPU settings to default
For some of the methods, you will need an administrator account on your Windows 11/10 PC.
1] Enable Hardware Acceleration in Windows
Enabling hardware acceleration can help to fix the distortions and artifacts on your screen. To fix the problem, follow the below steps:
- Open Windows 10 Settings
- Navigate to System > Display
- Click on the Graphics Settings link
- Turn on the “Hardware-accelerated GPU scheduling” option
Restart your computer, and check for the issue.

2] Update Graphics Driver in Windows
Check if there is an update for your Graphics Driver. You can do it in two ways. The first is checking on the OEM website, and the second is through Optional Windows Update.
Go to Windows 10 Settings > Update and Security > View Optional Update (under update button). Locate if there is a driver update available. Even if you check through the Device manager, the screen will bring you here. If there is an update, check the box and update.
Be aware that it may not always be a graphics card issue, and everything works fine when playing games and without any distortion. You will notice it only when using File Explorer, images, desktop wallpaper; the cursor might disappear, and images and text might appear fuzzy. You may also observe a pink-purple tint.

3] Remote Desktop Issue
Some users have reported that these lines and patches occur when they connect to another PC using a remote desktop. In this case, you can enable hardware acceleration.
- Open Group Policy Editor by typing gpedit.msc in the Run prompt (Win + R), and press the Enter key.
- Navigate to the following path
Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Connection Client.
- Locate and open the policy— Do not allow hardware-accelerated decoding. Please set it to Enable.
This policy setting specifies whether the Remote Desktop Connection can use hardware acceleration if supported hardware is available.
If this is enabled, the Remote Desktop Connection software will only use software decoding. Once enabled or left unconfigured Remote Desktop client will use hardware-accelerated decoding if supported hardware is available.
If it is already enabled or not configured, you can disable it and check if the issue is resolved. Hardware acceleration may or may not help, but toggling the setting helps to understand if this has an impact. Reconnect to the remote desktop, and check if you experience the same problem.

4] Nearby Magnetic Field
Magnets are known to cause distortion in display screens, and it has been observed that magnetic fields generated by speakers can also distort images. It could be possible that the speakers are generating magnetic fields.
Figure out the devices around the monitor, and check if any of them has magnets or electromagnets. Speakers are usually kept on both sides of the monitor. Turn them off, and check if the issue persists.

5] Reset GPU settings to default
Most OEMs offer GPU software that allows you to reconfigure the settings to default, with the optimal setting for your GPU and display. You can download the latest GPU software from the OEM’s support website. Once installed, open and apply the default or balance settings.
I hope the post was easy to follow, and you were able to resolve the issue where the PC screen was showing artifacts or distortion. If nothing has worked for you, it’s time to get in touch with the Hardware support team and ask for help. It is possible that you have to return the hardware or the laptop for repair if nothing helps.
