Windows 10: Second monitor has wrong resolution

for a while, I've been using a Dell E248WFPb (native 1920x1200) connected via VGA on my Dell Optiplex 7040 Micro successfully at it's native resolution. But I just moved the computer to another room, and now that same monitor is a second monitor to a Samsung 2343 (native 2048x1152) connected via DVI to HDMI adapter. The Samsung monitor runs great, native resolution and everything. But the Dell E248WFPb which is now a second monitor, I can't get to go to native resolution. Help!

:)

 

second monitor resolution

Everything worked great until I moved my computer. Now, I can not change the resolution on my second monitor. I am using

Windows 10. The resolution bar, only on monitor #2, is greyed out. I tried switching the monitors but either one is stilled greyed out when used as #2. Monitor #1's resolution can be changed , no problem.

Hi,



Thank you for posting your question in Microsoft Community.



I understand that you are facing issues with screen resolution. I will try to help you in fixing the issue.

To help you suggest more steps to resolve the issue, I would appreciate if you could answer the following questions:



What exactly happens when you try to change the screen resolution? Do you get any error message?



The recommended resolution on windows 10 is 1920 x 1080. Change the resolution to 1920 x 1080 and check.

The reason why your display was stretched sideways is because the resolution was in-corrected.



Here are the steps to change the screen resolution:

• Right Click the Desktop and select
  Screen Resolution.
• Click the Make text and other items larger or smaller link.
• In the Change only the text size section click the
  drop down menu to select the items you want to change.

Hope the information was helpful
