[SOLVED] Resize Output Image to Fit HDMI External Monitor

[OmneBonum]

The image is too big when output to HDMI monitor. A full-sized window, for instance, is chopped on all sides so that important buttons and text are located off screen.

In Windows I used Intel Graphics and Media Control Panel, and adjusted the scaling from 100 to 60 for both vertical and horizontal. That worked fine. I have done due diligence searching for a solution in forums and investigating the wonders of xrandr but nothing quite works.

Tried, pos, scale, -fb, -fbmm, transform, etc. Tried all the available resolutions. Tried many other things too numerous to mention.

Any thoughts? Appreciated!

What is the brand and model number of the monitor?

With the monitor connected, use this command in the Terminal and post the output: xrandr --prop

I could not find any info on the internet for the model number you gave.

There usually is a setting in the TV's on-screen display menu to turn off overscan mode by changing the input mode, which can be named: Just Scan, Full Pixel, True Pixel, Screen Fit, 1:1 Mode, Native Mode, Dot by Dot, 16:9 image scan, or possibly something else.

Here it is: https://www.sharp.co.uk/cps/rde/xbcr/do ... _OM_GB.pdf.

Page 33 of that PDF; the Sharp term is "Dot by Dot" it seems. You'll after adjusting this on the TV of course want to in Windows disable the computer-side adjustment again...

Well, there's a lesson in problem solving. Because I was able to do it through the computer for Windows, I assumed I had to do the same, only through some equivalent process, in my Linux GUI. As a result, it never occurred to me the problem could be easily solved through the monitor itself.

THANK YOU VERY MUCH!

P.S. For future seekers of wisdom who may stumble upon this: The menu item, once WSS was switched on, appears when you hit the WIDE button on the remote, then you need to select UNDERSCAN for 720p (not dot-by-dot, which is for 1080x and, in any case, does not appear on the menu.)
