How does the monitor not adjust the refresh frequency?

The display refresh rate in Display properties cannot be adjusted, but most of the display refresh rate cannot be adjusted because people do not choose the correct display type or the driver of the video card is incorrectly installed. The choice of display type is often overlooked, many users set the display type to "SUPERVGA" and so on, resulting in the inability to adjust the video card refresh frequency.

To know that the wrong refresh frequency parameters may be harmful to the display, so for the system can not recognize the display, should be in accordance with the most conservative default state to set (60HZ). The solution is to select the correct display type in the display properties, and if you are using windows that is not recognizable, choose a product that is close to performance. If the driver is the cause of the user reinstall the driver can be, because sometimes the sudden crash, the driver of the video card is lost.

Again, the display's refresh rate does not set too high, exceeding its standard refresh rate too much, it will burn the monitor or shorten its life. For this monitor it is best to install your own driver, do not blindly use high-end display of the driver. Second, do not remove the "Hide monitor not supported refresh rate" item in Windows, or it will cause users to use a refresh rate that the monitor does not support.
