Read the instructions on the link "Adjusting the Screen Resolution" on the CD, and then select the correct
resolution, refresh rate and make adjustments based on these instructions.
How do you use a VGA extension cable?

through the instructions in the "Adjusting the refresh rate" section on the link "Adjusting the Screen
Resolution". It is normal for blurring to occur due to conduction losses in extension cables. You can minimize
these losses by using an extension cable with better conduction quality or with a built-in booster.
