Windows 10: Can I Decouple Two Monitors' Display Settings?

I have a Lenovo 580T, Windows 10.1903; with an attached second monitor, Dell 2311H, which I had also used for my T530 running Win7.

Of course I am having display issues, probably because of Win10's DPI Scaling policy. The recommended scaling is 125% for the original screen, and the scaling is set at 100% for the second screen. The second monitor renders fine enough, if not a tiny bit blurrier than on the Win7 machine, but certain legacy apps I run appear blurry on my main (laptop) screen:









I found a web page online that recommends how to fix this: apply custom scaling of 125, same as the "recommended" default scaling, sign out and sign back in, and voila, your blurriness will be fixed without changing anything else.

Except not so voila. The legacy app does appear very sharp and at mostly the same size as before, but now the scaling on the second screen is freakishly big:









When I open display setting to see the result of my fix, the scaling is grayed out and set to 175% for both monitors, not the 125% I chose. I tried as much as I could to decouple the scaling for the laptop monitor and the second monitor, but I can't figure out how to make it stick or render properly.

I did go to device manager to check drivers and did successfully update the Generic PnP monitor driver to the specific Dell 2311H driver, but that did not help. The issue appears in native Display settings, and my inability to decouple the monitors through them.

Unless I am missing something? Can anyone suggest a fix for this?

External monitor display settings

Hi,



Thank you for posting in Microsoft Community.



I understand that you are facing issues with the display scaling on your external displays. We will certainly look into this for you.

As you are using Vizio TV, you may have to try using custom resolution settings if the in-built settings do not provide the required settings.

For better clarity, please let us know:

• What is the version of Windows 10 that is currently installed on your computer? You can click on Search and type
  winver.
• Are you aware of any recent changes to the system, such as updates, after which you are facing this issue?
• What is the make and model of your computer?

Meanwhile, I would suggest you to check the steps mentioned in the Workaround section in

Windows scaling issues for high-DPI devices

I would also suggest you to check the Display drivers. Please refer

Troubleshoot external monitor connections in Windows 10

Set up dual monitors on Windows 10



Let us know how it goes.

Can not use two monitors. Error message: "The display settings could not be saved. Please try a different combination of display settings"

Hello,



Thank you for writing to Microsoft Community Forums.

• Since when are you facing this issue with the monitors?
  
• Which build version of Windows 10 is installed on your computer?
  
• What happens when you try to duplicate the monitors?
  

I suggest you to try changing the display ports of the monitors and check if the second monitor is getting detected.



I suggest you to follow the methods mentioned below and check if that helps.

Method 1: Try rolling back the driver.

To roll back the driver to previous build follow the steps mentioned below:

1. Press and hold the Windows + X key on the keyboard.
   
2. Select Device manager.
   
3. In Device manager, expand Display adaptor.
   
4. Right click on NVIDIA
   Drivers and select Properties.
   
5. Navigate to the Driver tab and click on Roll Back Driver.
   
6. Restart the computer.
   

Method 2: Change the screen resolution.

1. Go to Settings>System>Display.
   
2. Under Resolution, set the resolution as 1024 x 768.
   
3. Set the same resolution on the other monitor.
   

Please reply with the status of the issue, we will be glad to help you further.
