Can't get triple head / 3 monitor setup working. Tearing hair out here

[jonah1980]

Hi can anyone please help with my 3 displays on Ubuntu.

I have three 2560x1440 Asus monitors (I know - very nice! At least they would be..!)

I have an integrated intel gpu which I plugged all three monitors in to with dvi, hdmi and vga.

I couldn't get the vga one past 1920x1200 though!!

So I've now added an nvidia graphics card and set my bios to use both. But even though the 3rd screen is on hdmi on nvidia I still can't get full resolution the result is two screens look great and one looks terrible!

What is weird is the 3rd screen now on nvidia (with the other two still on intel integrated) has the same resolution of 1920x1200 using hdmi as it did on integrated using vga!!!??

Can anyone please help me to fix this?

I've now removed that nividia card for the 3rd monitor and plugged all 3 back into the intel integrated gpu...

So I'm still stuck with one lower res monitor but having a 2nd graphics card didn't help anything so I thought I may as well remove it.
