The old computer is a CRT monitor. The default setting of the graphics card is 85HZ refresh rate, while the refresh rate of the LCD monitor is generally 60HZ.So it will exceed the refresh rate on your old computer and cannot be displayed normally.It can be displayed on the new computer, which means that the graphics card of the new computer can automatically identify the maximum refresh rate of the display and automatically adjust the refresh rate to 60HZ, so the new computer is normal.
