Hello I recently purchased an ultrawide monitor. I've wanted to use it at 3840x1080 resolution, but when I choose it, only the middle section of the screen is used. The mouse scrolls very slowly horizontally through the screen though which is interesting.
2560x1440 uses the entire screen, but everything looks stretched very wide.
It is nothing to do with a gender as you know
A part of my job requires much searched on the net. I developed a skill to select the best combination of keywords over the years.
I have also tried using xrandr Which gives an error stating that size 3840x1080 is not found in available modes, but it does seem that it should be available given the xrandr options with no parameters.
This has me wondering if the UltraWide monitor actually sends a signal as if it was Two Monitors at 1920, that is then utilized as a single display across two monitors (That is actually one monitor screen).
If my speculative musing above is the case; then I have nothing. That would be problematic (and unsurprising... as from the Monitor Manufactures point of view, that would be the easiest way to program the monitor).
It is only a speculative thought at this time.
I am an idiot and didn't think about the aspect ratio on the monitor. Once i changed the monitor aspect ratio via the menu buttons on the monitor itself I was able to get everything working.
