I'm trying to fit the size of the videoprojector screen to the actual wall size. there is some option to resize in the projetor's menu itself but it is not sufficient to resize it properly.

I have seen the option of using

xrandr --set underscan on

but unfortunately that does not work for me, as I have an intel graphics card on my laptop (Intel® UHD Graphics 620 (KBL GT2) and I have read that this option is only valid for NVDIA cards.

I have been lead to belive that I may achieve that through a series of command

xrandr --transform

For example, i've tried doing

xrandr --output eDP-1 --fb 1800x1000 --transform 1,0,-60,0,1,-30,0,0,1

(found from this page about cropping part of the monitor off)

but I am left with the right and bottom part which are unusable on the display. What I would like to achieve is to rescale the whole screen into a smaller zone, which is still to be determined, possibly playing with some parameters, but for the sake of the example let us imagine that this means reducing indeed the overall size from 1920x1080 to 1800x1000.

How could I then rescale the whole screen instead of cropping part of it off? Thank you very much for your help.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
