How can I restore the desktop when I move it to the right?

Problem:

How to restore the desktop from moving to the right

I also forgot how I got it. Anyway, I couldn't get it back. 1/4 on the left of the desktop was black. I tried to use the buttons in the lower left corner of the monitor to adjust the effect. The horizontal position was always not in place. there is a result that can be restored to the factory location. The result is more biased to the right. Can someone help me?
Question added: it should not be a problem with the monitor. At that time, I went into the game and found a black one on the left of the screen. Later I realized that the resolution was incorrect. I tried to adjust the horizontal position of the screen and then it went down -,-

Answer:

First, let's see what Chip your video card is. It's ATI, nVidia, or something else. Go to "driver home www.mydrivers.com" to download the driver and control panel of the video card,
The graphics card drivers of ATI are divided into "Pure driver version", "Common Control Panel Driver", and "Media Center driver". We recommend that you find the driver of the "general control panel" version, download and run the tool to install it. (If you cannot find the "Common Control Panel Driver", install the "media control center driver". However, you must install Microsoft. NET 2.0 Framework), take the Common Control Panel Driver as an example: After the installation is completed and restarted, enter the Display Properties, click the "Settings" tab, and click the "advanced" button to enter the graphics card attribute settings menu, click the "display" tab and click "Monitor" to go to the "Monitor" attribute. On the "adjust" tab, you can set the screen to scale up or down.
NVidia graphics card and ATI are similar, but the driver has a control panel in no matter what version. It is relatively simple. After the driver is installed, you can enter the display attribute advanced to enter the graphics card attribute settings, if it is a newer driver, we recommend that you select the original control interface mode, so that you can find the screen adjustment project on the left side, click to enter to adjust.
Note: Incorrect option adjustment may cause damage to the video card or display. Please confirm the function and then set it. If you are not clear, you can view the help information.
