Windows 10: Correct monitor display resolution unlisted when second monitor is connected

I am attempting to connect my laptop Dell Inspiron to a dual monitor arrangement one 1920x1080, and an ultrawide 3440x1440. When either single monitor is connected, the display resolution is correct and everything works well. However when connecting the second monitor, the resolution of the ultrawide reduces to 1920x1080, with no option to increase this. 3440x1440 is also not displayed in the 'list of valid modes' accessed under advanced display--> display adapter properties --> List all modes.I have checked graphics, and display adapter drivers and confirmed that the most up-to-date

Monitor is detected but display resolution is not correct


One of two possibilities:

1. Driver is still not correct, as you don't have the listed resolution to go to recommended for that monitor. If it is using a driver win 10 installed and not the manufacturer, then you need to try the manufacturer driver, list the display driver from device manager and we can go from there.

2. Card in PC (Is it a card, or integrated mainboard graphics?) doesn't support that resolution, hence driver not listing it, etc.

Other possibility - what does the system show for the monitor listed in device manager?

 

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.

 

Monitor is detected but display resolution is not correct


i bought a new monitor yesterday (AOC E2270SWHN) and i found that the screen was really stretched out when I connected it to my pc. Here is a picture:


When I went into the settings I found that there was no option for 1080x1920 and was very confused. Like I said, my pc recognises the monitor but does not show the correct screen resolution. I have tried everything, from reinstalling the drivers to downloading about 10 apps that claim to change the screen resolution but end up doing completely nothing. Please help me before i shoot myself from fustration. Thanks!!
