Changing the Terminal Display settings

[lonesoac0]

Hello all,

As you can see in the attached image, the resolution is just not quite right. How can I adjust a resolution of a 100% local terminal interface?

Thank you.

This is a TV?

For historical reasons TVs often enable something called "overscan" by default. Look in the manual of the display to disable it.

If local console doesn't work right, you can try setting a VGA mode in the grub boot options

Or there's also ssh

There will be knobs/selectors on the physical TV

Actually I have an (4K-) Aquos TV in reach and I gave it a try. The (old) connected computer has "Xeon E3-1200 v3 Processor Integrated Graphics Controller".

Overscan is active, some characters on all four edges are missing. This confirms @lonesoac0's experience.

Although this TV has configuration settings like "HDMI EDID" playing around here did not help.

The solution was found in the PICTURE settings: I can select an Aspect Ratio, which was set to 16:9 - which sounds right, doesn't it? No. Besides some zoom level I was offered "Full Screen" - and this did the trick! Now I can see all 240x67 characters and the border of "mc" looks correct.


Rant: this is 2024! Back in the 80's, when VGA and Hercules invented new resolutions, we had to configure Modelines to make X11 deliver some displayable timing to that heavy CRT. It was crazy, difficult and actually dangerous - you could blow up the TV because the ~25 kV output increased linear with the (forced by you, and officially out of range) frequency. 30 years later that problem is not completely solved. EDID is just another workaround, that usually works.
