Set up in the system

1. The resolution of the display refers to the number of pixels in the screen area, which is calibrated with rows and columns. In the same large area, the higher the resolution, the more realistic the image. However, this is subject to video and monitor limitations.

The first step: on the Windows desktop, move the mouse to the taskbar, click Start One Settings Control Panel, double-click the Monitor icon, click Settings, or right-click any space in the desktop and click to select Properties from the shortcut menu that pops up. (see above for illustration)

Step two: In the Screen Area option group, drag the slider to the desired resolution, and then click OK. Then, for different video cards, the system will give different ScreenTips. If the screen jitter is severe during setup, the resolution is not appropriate and the original settings are automatically restored. (see above for illustration)

The third step: the color setting is generally combined with the resolution settings, because the display capacity of the graphics card is fixed, display resolution and display color of the product by the memory capacity of the constraints, not too big. So the higher the display resolution, the fewer colors are allowed to set. Click the Drop-down button at the right end of the color box to select the appropriate color setting from the Drop-down list, and then click OK. (see above for illustration)

Fourth step: Windows can change the display refresh rate. The higher the display's refresh rate, the smaller the flicker, and the more comfortable we feel. The refresh frequency should be set according to the refresh frequency index in the display manual.

Click Advanced, and if the monitor and video card allow adjustment, the option is displayed in the Refresh Frequency drop-down list box. Do not exceed the allowable values on the display specification when selecting. When selected, click OK to exit.
