There is also a possibility that the graphics card driver file of the cash register is damaged, which will also lead to a blurry screen.

Problems with the connection cable (VGA) between the display screen of the cash register and the host computer will also cause a blurry screen. It may be a loose connection, or it may be that the connector is oxidized and the power supply is insufficient.

You can remove the dust on the memory module by wiping, and then turn on the computer to check whether the problem of the blurry screen is solved. If the problem is not solved, the memory module needs to be replaced.
