有屏幕问题？最近更改了您在Windows中的(Windows)显示分辨率(display resolution)，现在出现无法更改的空白或黑屏？发生这种情况时很烦人！这在我身上发生过很多次，我不得不说， Windows(Windows)没有内置机制来检测显示器是否支持特定的分辨率或刷新率，这真是太糟糕了。
无论如何，如果您已经处于这种情况并且您所看到的只是BIOS 加载(BIOS loading)、Windows 徽标(Windows logo)，然后一旦 Windows 开始加载，屏幕就会变成空白，那么有两种基本方法可以恢复您的原始设置。
- 将计算机连接到更高级的显示器(Connect computer to a more advanced monitor)- 再次查看所有内容的一种方法是将计算机连接到可以支持更高分辨率的显示器。因此，如果您有一台旧的 15英寸显示器(inch monitor)并且无法显示 1600×1200(display 1600×1200)，请将显示器连接到较新的屏幕，登录Windows并将显示设置更改回原来的样子。
- 以安全模式启动计算机 -(Start the computer in Safe Mode –)恢复原始显示设置的第二种方法是以安全模式(Safe Mode)启动，这基本上以精简状态加载Windows 。安全模式(Safe Mode)以较低的分辨率加载，因此允许您登录并更改设置。要以安全模式(Safe Mode)启动，您只需在计算机启动时按住F8键。(F8 )这通常是当您看到制造商徽标和正在加载的BIOS时。(BIOS)按下 F8 后，您将看到一组选项，如下所示：
继续并选择安全模式( Safe Mode)。如果由于某种原因安全模式(Mode)不起作用，您也可以尝试选择启用 VGA 模式(Enable VGA Mode)。启用VGA 模式(VGA Mode)对于您尝试将桌面扩展到另一台显示器或选择(monitor or select)另一台显示器用作主显示器的情况也很有用。
有时可能会出现的问题是， Windows将信号发送到与您连接外接显示器的端口不同的端口，因此它会在加载时为您提供空白屏幕。同样(Again)，Windows不会自动检测到没有连接显示器，也不会恢复到原来的设置！
现在您在Windows中，您可以通过右键单击(Windows)桌面(Desktop)、选择属性(Properties)并单击设置(Settings)选项卡来更改分辨率或刷新率。在Windows 7/8中，您必须选择屏幕分辨率( Screen Resolution)。
For screen resolution, move the slide bar over to the LEFT. This will lower the resolution and allow your monitor to display Windows correctly. In Windows 7, you just pick a resolution from the drop down box. If the refresh rate is too high, click on the Advanced button or Advanced settings link and then click on the Monitor tab.
Here is also where you can change back your primary monitor to 1 if 2 gave you a blank screen. Also, you can uncheck the extend my desktop option.
From the drop down, choose a lower value for the screen refresh rate. Go ahead and reboot your computer normally and everything should load up fine.
请记住(Remember)，在Windows中，当您更改显示设置时，请始终先单击 应用(APPLY)。如果您只是单击“确定(OK)”，则不会出现如下所示的对话框，如果您在 15 秒内没有回答， (t answer)Windows将恢复为原始设置。
当您单击Apply时，Windows会将显示更改为您选择的显示，在这种情况下，如果它不支持，屏幕将变为黑色或空白。但是，此对话框将打开，如果您不单击(t click)任何内容，它将恢复为原始设置！因此，您不必浪费时间通过安全模式(Safe Mode)等。任何问题，发表评论。享受！
Fix Blank Screen After Changing Computer Display Settings
Having screen problems? Recently chаnged your display resolution іn Wіndows and now left with a blank or black screen which you can’t change back? It’s аnnoying when this happens! It’s happened to me numerous times and I have to say that it’s quite terrible that Windows doеs not have a buіlt-in mechanism to detect whethеr or not a monitor can sυpport a particυlar resolution or refresh rate.
Anyway, if you’re already in the situation and all you see is the BIOS loading, the Windows logo, and then the screen just goes blank once Windows starts to load, then there are two basic ways to get back to your original settings.
- Connect computer to a more advanced monitor – One way to see everything again is to simply connect the computer to a monitor that can support a higher resolution. So if you have an old 15 inch monitor and it can’t display 1600×1200, connect the monitor to a newer screen, log into Windows and change the display settings back to what is was originally.
- Start the computer in Safe Mode – The second way to get back your original display settings is to start up in Safe Mode, which basically loads Windows in a stripped down state. Safe Mode loads up at a lower resolution and therefore allows you to log in and change the settings back.To start up in Safe Mode, you simply press and hold the F8 key when the computer starts to boot up. This is usually when you see the manufactures logo and the BIOS being loaded. Once you press F8, you’ll be presented with a set of options as shown below:
Go ahead and select Safe Mode. If for some reason Safe Mode does not work, you can also try selecting Enable VGA Mode. Enable VGA Mode can also be useful for situations where you try to extend your desktop onto another monitor or select another monitor to use as your primary monitor.
The problem that can sometimes occur there is that Windows sends the signal to a different port than where you have your external monitor connected and it will therefore give you the blank screen whenever it loads up. Again, Windows does not automatically detect that there isn’t monitor connected and it won’t revert back to its original settings!
Now that you’re in Windows, you can change the resolution or refresh rate by right-clicking on the Desktop, choosing Properties and clicking on the Settings tab. In Windows 7/8, you have to choose Screen Resolution.
For screen resolution, move the slide bar over to the LEFT. This will lower the resolution and allow your monitor to display Windows correctly. In Windows 7, you just pick a resolution from the drop down box. If the refresh rate is too high, click on the Advanced button or Advanced settings link and then click on the Monitor tab.
Here is also where you can change back your primary monitor to 1 if 2 gave you a blank screen. Also, you can uncheck the extend my desktop option.
From the drop down, choose a lower value for the screen refresh rate. Go ahead and reboot your computer normally and everything should load up fine.
Remember, in Windows, when you change your display settings, always click APPLY first. If you simply click OK, you won’t get the dialog shown below whereby Windows will revert back to the original settings if you don’t answer within 15 seconds.
When you click Apply, Windows will change the display to what you chose, in which case the screen will go black or blank if it can’t support it. However, this dialog will be up and if you don’t click on anything, it will revert back to the original settings! So you won’t have to waste time going through Safe Mode, etc, etc. Any questions, post a comment. Enjoy!
