<p class="MsoNormal">Use Case: I have a stretched LCD panel where the manufacturer literally "cuts" the display such that the vertical resolution it reports is greater than what's visible. Rather than adapt my software to fit a particular resolution I thought
it would be interesting to scale the entire desktop along the vertical direction to within the physical constraints of the monitor.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m trying to configure my screen to occupy the upper half of a single monitor such that the entire desktop is still displayed. The following command successfully shows only the upper half of the screen (1080p resolution):<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">xrandr --fb 1920x540 --output VGA1<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I would expect the following command to then scale the screen while still occupying only the upper portion of the monitor:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">xrandr --fb 1920x540 --output VGA1 --scale 1x.5<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">However, this ends up scaling the display and occupying the entire monitor.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I've tried several monitors (using VGA) with no change. I've also tried adding new modes with half the vertical resolution, with and without halving the refresh rate.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">How can I do this with xrandr? If not, Is there some other method to go about achieving this?<o:p></o:p></p>
