Hi, does anyone know if its possible to have a window go fullscreen across a proper subset >1 of one's monitors? Allow me to clarify what I mean. I have my monitors arranged as so (DP# just being the DisplayPort-#):

| DP1  |     |     |     |
+------+ DP4 | DP5 | DP1 |
| DP9  |     |     |     |

What I was hoping to do is have a window go fullscreen on DP1, DP4, and DP5. I realize there is the fulscreen global option, but because DP1 and DP9 have a lower PPI than DP1, 4, and 5, there is part of whatever cut off on the top of DP1 and the bottom of DP9.

I realize this is a niche case that very little people (if any) car about, but on the off chance anyone knows, it'd be awesome if you could post the solution. otherwise I might look into a feature request

Make a script that floats the current window via i3-msg then uses xdotool to move it to the corner of dp4 and resize it to be the appropriate size to fit across all 3 monitors.      
#!/usr/bin/env sh
i3-msg floating enable
xdotool getactivewindow windowmove xcord ycord
xdotool getactivewindow windowsize xsize ysize

bindsym something

This is as close as you can get there is no way to be actually be fullscreen across more than one display but not all of them.

thanks for the help! this kinda does what I was hoping. doesn't work for fullscreen video though. but I don't think thats unexpected. it'll work well enough for everything else, though.
