[Trisquel-users] Re : Trisquel 8 install didn't detect my monitor, gave wrong resolution.

I doubt the problem is with the monitor but rather with the video card.  The  
kernel is responsible for the abstraction of the hardware.  Trying a newer  
kernel is easy and may solve your problem.  After all, it could be related to  
change in Trisquel's configuration of the kernel, a change that the  
Linux-libre project may have not made.
