Windows 10: my monitor doesn't display the right resolution

My monitor is a 3840 x 2160 monitor and is running like it is 1920 x 1080 and won't go back to being smooth and is just all blocky. I don't know if this has anything todo with my signal strength being 1920 x 1080 but I don't know how to fix that

Display Resolution for two monitor have different settings

Hi,

Thank you for writing to Microsoft Community Forums.

The display resolution depends on the monitors that you have plugged into your computer. The display resolution modes will vary with each display based on the video card device, monitor size, video driver, and monitor driver.
By default, Windows chooses the best display settings for your PC based on your monitor, so it is recommended to set the screen resolution of the display to the (Recommended) native resolution to get the best display on your monitor.

To have better clarity on the issue, let us know the model numbers of your monitors, so that we can provide you the exact display resolution which is recommended to your monitors.

Meanwhile, try the below methods and see if this helps.

Changing the Display Resolution from Settings.

Step 1: Right Click on an empty space on the desktop and click on
Display Settings.

Step 2: In the
Display Settings window, scroll down and click on 'Advanced display settings' option under
Multiple displays.

Step 3: Then, click on
Display adapter properties for Display 1, Display 2, or
Display 3; whichever monitor you want to change the resolution for.

Step 4: Once the Display properties pops-up, click on 'List All Modes' option.

Step 5: Select a display mode that you want for the selected display and click on
OK.

Step 6: Then, click on
Apply and OK for the changes to take effect.

If these steps don't work, try reinstalling the driver by opening
Device Manager, right-click on the monitor drivers, and select
Uninstall. Restart your PC and Windows will attempt to reinstall the drivers.

Hope it helps.
