The desktop computer screen size is fixed and cannot be adjusted, but the screen resolution size can be adjusted. What screen resolution and refresh rate the 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 when the display and graphics card support a certain resolution and refresh rate mode. The specific operation steps are as follows:
1、 Correctly identify the display and graphics card and install the driver: It can be detected by special tools such as Master Lu and 360 Driver Master to determine whether the display and graphics card models and corresponding drivers are correctly installed.As shown in the figure below, the video card and display have been correctly identified, which also means that the driver has been correctly installed (of course, you can also try to update the driver). If the specific model is not displayed or there is a prompt that no driver is installed, you can identify and install it through 360 Driver Master.
2、 Set the screen resolution correctly: take WIN7 as an example, and the operation is as follows:
1. Right click an empty part of the desktop, and click Screen Resolution;
2. Click Advanced Settings and select List All Modes;
3. Set the resolution and refresh rate according to the recommended or optimal values of the system, or select the desired resolution mode, and then confirm.
matters needing attention: The resolution and refresh rate modes supported by both monitors and graphics cards can be set on the premise that both monitors and graphics cards have been correctly identified and the drivers for both have been correctly installed.If the system cannot set a certain resolution and refresh rate, this display mode is not supported by the hardware. It is better to set it to another resolution and refresh rate mode supported by the hardware.Alternatively, upgrade the hardware that can set this mode.
Dear Lenovo users!You can right-click the blank space on the desktop, select the screen resolution in the pop-up menu, and then select the highest resolution.Thank you for your support for Lenovo, and wish you a happy life!
