Secondary display connected to laptop not full screen or out of range

Super User Asked by Shobhit Tewari on February 22, 2021

I have a laptop name DELL Inspiron 5577 Display resolution: 1920*1080

I have an old monitor name LG Flatron E1942C Display resolution: 1366*768

Now I want to connect this monitor with my laptop to make an extended display. When I connect to this monitor through (HDMI -> VDI), I am having 2 kinds of issues.

Issue number 1: The display is not full screen or as expected. I am attaching a photo of how the display is. Please see it.Photo

Issue number 2: When I try to play around with different kinds of resolutions with Windows display manager or intel dedicated GPU software, it goes 67.4khz/60hz signal out of range.

I updated my drivers and did anything I found on googling. My laptop display is top-notch. I can see Rick Sanchez doing all the small movements but my extended monitor display is like, "Nope, I’m not gonna let you do it so easily".

Please help someone 🙂

Your monitor has only a VGA input, so I'm assuming that "VDI" is a typo for VGA, not DVI.

The image is not positioned correctly, but the scale appears to be about right. This happens only with analog connections such as VGA and is caused by timing offsets being off (very off in your case). Use monitor's on-screen menu to adjust it. According to the manual this setting is on the 3rd tab (horizontal and vertical controls).
