S3220DGF, image doesn't fill screen

I've had a Dell s3220dgf monitor for a few years and it's worked great, but recently I noticed that the image doesn't fill the entire screen. There are thin black bars on the left, right, and top of the image (but not the bottom!). I'm not sure what's changed, but I'm unable to fix it.

For the record, I've got the monitor plugged in via the DisplayPort and it's running at 2560x1440. I am running Windows 10 and using an NVIDIA 3080.

Things I've tried:

- Changing the resolution in Windows Display Setting and via the Nvidia Control Panel

- In the Nvidia Control Panel, I've checked to see if there's any display scaling happening, but there isn't

- I've reset the monitor to factory settings

- The monitor's Aspect Ratio is Wide 16:9. I tried setting it to Auto, but that didn't change anything.
- I've run the monitor's self diagnostic, which looks fine except it has the same borders.

- I can't find any setting in the monitor's menus for adjusting the scale of the image.

I'm at a loss at this point. Does anyone have any ideas? Thanks!

Verify to see which is the recommended resolution in Windows display settings.  Then verify the frequency to match with the native of your display.

Thanks! According to Display settings in Windows, 2560 X 1440 is the recommended resolution.

None of the Refresh Rate options say recommended, but it's set to 119.998. The other options are 59.951 and 165.080. Not sure why they aren't whole numbers, but when I check the display adapter properties and check the refresh rate there, it's says the monitor is set to 120hz.

Try the lower frequency of 60 Hz, or 59.951 Hz.  If there is no change to fill screen, turn off the adaptive sync option by selecting no sync.

I lowered the frequency to 59.951 Hz through Window's Display settings, but there was no change. I then went to Nvidia's Control Panel and disabled G-Sync, which is what I think you meant by disabling adaptive sync. No change there either.

There is not much else to check besides all the reset you have done so far.  You may consider to test with HDMI connection to see if any improvement.

Otherwise, if access is available, test your computer with a different monitor and test the monitor connecting to another PC or laptop.  That would narrow down the issue with the PC or the monitor.

Open the online S3220DGF User's Guide to page 52.

Post pictures of the screen while running the disconnected from system BID (Built-in Diagnostics). Do the full colors fill the entire screen?

I tried the Built In Diagnostics disconnected from my PC and the colors don't fill the entire screen.

Click the "Get Help Now" icon on the right to start a live chat session. Provide to them the private S3220DGF Service Tag. If still under the purchased warranty period, ask for a monitor exchange.
