Radeon 7770 and Dual monitors (HELP)

WhisperingOrphan

Hello all :)

This is the first time I've ever tried to install two monitors, Ive I've researched after work for the last week and a half to no avail. So if someone could point me in the right direction I would be extremely grateful.

Radeon 7770
Driver is installed and working fine from what I've seen.

Output from xrandr:

I'm not sure what all output would be needed to diagnose the problem so please excuse my ignorance, and again thanks for any and all advice. --Mr.Free
 
It has not detected anything connected to the HDMI port. Support for the 7770 may not be complete yet, or there might be a problem with the HDMI cable or monitor. Check the connections.
 
Ah, that would do it. Please post the output of xrandr now. For my two DVI monitors, I use this command:
xrandr --output DVI-0 --primary --mode 1920x1200 --pos 1280x0 --output DVI-1 --mode 1280x1024 --pos 0x0

That puts the larger 1920x1200 primary monitor on DVI-0 on the right.
 
Thank you. I have gotten everything to work now. The problem I have now is on my HDMI LCD screen, the desktop is too big for the monitor.

I googled for a while and think it's overscanning?

Here is my ~/.xinitrc:

Code: 
xrandr --output DVI-0 --right-of HDMI-0
 
Yes Sir, it has the HDMI and DVI cable slots aswell. I have went through the menu option on the tv and It doesnt seem to have an "aspect ratio"option

with roxterm opened up in fullscreen the terminal shows
e@orphan:~ %
instead of
mrfree@orphan:~ %
 
It's not the aspect ratio, it's just how much overscan is used. The monitor might not have a menu entry, or might call it something utterly unrelated.
 
Sorry been working 24-7. I found the overscan on the TV. it helped a[]lot but It's still a bit off

Instead of
mrfree@orphan:~%
I get
ee@orphan~%

The bottom of the screen is cut off as well, I can't see my i3-bar.

Thanks for your patience and sorry for the trouble.
