It should be poisoning. Look at this.

Lock the resolution of the desktop:

You can run REGEDIT and find it by modifying the registry.

HKEY _ local _ machine \ system \ current control set \ control \ class], open the "class" key and you will see a large row of keys, similar to.

{ 4d 36 e 96 e-E325- 1 1CE .。 }

If you select one of the keys, you will see some key values, such as Default and Category, and indicate the types of devices, such as Modem and Keyboard. Open these {4d36e96e-e325-11ce one by one. . } key until the data value of "Class" is "Monitor". Ok, we have found the registration information of the control monitor, and the next step is to set the default value in it.

Open the key you just found (under the directory tree). There should be at least 1 keys in it, which is called "0000". There may be other keys here, such as "000 1" and "0002". If there is only one "0000" in it, it will be simple. You can modify it directly in "0000" according to the following methods. If there are multiple keys, you must find out which key controls your display one by one. The method is to modify the keys one by one according to the operation of modifying the default values, and immediately check with the method of "Check whether the default values have been modified". If it is consistent, it means that this key controls your display, otherwise it is not.

"Modify Default Value Action" method:

Open "0000" or any other key you find, and you can see that there is a "MODES" key in it. Open it, and you will see a key that shows the maximum resolution of your monitor, such as "1600, 1200". Now suppose you want to reach 85Hz at the resolution of 1024*768. Then the operation is as follows: right-click under MODES to create a new project named1024,768, right-click in1024,768 to create a new string value "Mode 1", right-click to select Modify, and set the data value to "85-"

Method of "Check whether the default value has been modified":

Go to Display Property Settings to see if the resolution is set for you. If not, it means that the key like "0000" you modified is not the key that controls your display now. You can then add values to other projects, such as 000 1. Only in the end, the graphics card property bar only has an option of 85HZ refresh rate.

3. After uninstalling, select "Update Driver". At this point, you need to download a driver wizard software. After opening the software, select Automatic Detection. After the test, reinstall and restart the computer.

Method 2:

1. Press "F8" to enter advanced mode;

The influence of screen resolution on the computer;

There is something wrong with the screen resolution, which will not have any special influence when we use the computer, but the screen will become a flower screen. This is the performance of the screen resolution problem, so it will be very inconvenient for us to browse information or process files.

Causes of screen resolution problems:

The main reason for the screen resolution problem is the computer graphics card problem. So how do you know that there is something wrong with its graphics card? Just look at the graphics card in Device Manager. At this time, we can clearly see that there will be a yellow warning sign on the graphics card.

3. What is the reason why the computer resolution always changes automatically?

1. may be a driver problem, a software problem, or a loose interface.

2. What kind of screen resolution and refresh rate a computer can set depends not only on the monitor and its driver, but also on the graphics card and its driver. In other words, the operating system can set the resolution and refresh rate of this screen only if the monitor and graphics card support a certain resolution and refresh rate mode.

3. If the hardware is not recognized correctly and an inapplicable driver is installed, there may be incompatibility between the driver and the hardware, resulting in a change in resolution.

4. You can use hardware testing tools such as Master Lu and 360 Driver Master to test and determine whether the models of monitors and graphics cards and the corresponding drivers are installed correctly.

5. Set a uniform resolution or uninstall the software that causes unstable resolution.

6. Preventing virus infection will affect the resolution.

7. If the above operation fails, you need to reinstall the system to eliminate the possibility of hardware failure (such as poor contact of the graphics card and poor heat dissipation). ).

4. The screen resolution of the computer has been changing by itself. What could be the reason?

Friend, I'll give you five ways:

On the browser. Find "View (V)" and click the mouse to open it, which contains "Text Size (X)". Just drag the mouse to the right and select it. It depends on which setting suits you! Generally choose "medium (M)"!

2. Press and hold "Ctrl" on the keyboard, and then scroll the mouse wheel back and forth to adjust the font size!

Reset resolution

Right-click the desktop, find Properties, click Settings, drag the scroll bar with screen resolution, set the appropriate mode, click Apply and OK, and then click Save! (Recommended resolution: 1280x768)

4. If you can't find the right one, in the settings, click Advanced next to Troubleshooting T, click Monitor, find the screen refresh frequency S, click V, find the setting of 60 Hz, click Save, and then drag the screen resolution scroll bar in the settings to make appropriate settings. (Recommended resolution: 1280x768) 5. If there is a virus or Trojan in the computer, the font will also become larger. I suggest you download "360 Stubborn Trojan Virus Killing" for a "comprehensive killing"! . .

5. How does the computer resolution change by itself?

The resolution of the computer has changed. The settings may be incorrect, or the resolution may have been accidentally reset.

1. Click the right mouse button in the blank space of the desktop. 2. Select the screen resolution in the right-click menu. 3. Find the solution in the pop-up dialog box. 4. Click the drop-down button. 5. Select the appropriate resolution in the drop-down menu, and then click OK. 6.

Repeat items 4 and 5. 7. If the desktop content is the right size, just click Save Changes.

If the above method doesn't work, or the resolution is set to gray, it is a graphics card driver problem. Download a driver wizard software, click Update Driver, and adjust it to the appropriate resolution by modifying the resolution after installation.
