Second monitor screen resolution problem

Hi,

For us to properly isolate the issue with your second monitor screen resolution, we would like to know the following:

• 
  Were there any changes made on your computer prior to the issue (e.g., updates, software installation)?
  
• 
  When did the issue first begin?
  
• 
  To make sure that we have not missed on anything, what troubleshooting steps have you done so far?
  

In the meantime, we suggest that you try resetting your monitor settings, and check if the issue still persists. You may refer to your monitor on how to reset it.

We look forward to your response.

using a monitor to extend my screen

Hi Lou,

There are several possible reasons why your LCD monitor suddenly stopped working. It could be that the graphic driver is outdated or could be the cable used is already damaged.

For us to isolate this problem, we would like to ask the following information:

• Were there any changes made on your computer prior to the issue?
• Have you installed any updates?

In the meantime, please try the following suggestions and see if your laptop will detect the LCD monitor:

• Update the graphic card driver. Check out Update drivers in Windows 10 for the steps.
• Use another cable. Try using another VGA cable to connect the LCD monitor to the laptop.
• Connect the LCD monitor to another computer. To help us isolate the issue, try connecting the LCD monitor to a different computer.

Please let us know how it goes. We're looking forward to hearing from you.

Regards.
