Xorg setting low resolution with double HDMI output despite forcing to full HD

[Francesco Nwokeka]

Hello all,
    I have an Intel NUC with dual HDMI output. Recently I've been experiencing 
a problem with the output resolution of the screens. When booting the system i 
get screen resolution inferior to what I actually try to set via .xinitrc file:

xrandr --output $(xrandr -q | grep "\sconnected\s" | cut -f1 -d" ") --mode 
1920x1080

This command sets the resolution to fullHD on all connected screens that can 
be detected. What's happening lately is that the resolution is defaulting to 
1280x800 (the projectors' "default" resolution even if the projector is HD 
capable).

As xrander shows, both projectors support HD resolutions but are currently set 
on a lower resolution despite the previous command to set it to 1920x1080:

Screen 0: minimum 8 x 8, current 1280 x 800, maximum 32767 x 32767

Does anyone have any idea to what might be the problem/solution?


Thanks,
