multiple monitors dead zone

[ether_joe]

What's up everybody ...

So I have just installed LM14 with MATE and I'm generally very impressed. I'm running three monitors in portrait mode, and I'm seeing a dead zone of maybe 200-400 pixels. When I go into Monitor configuration, the little widget to drag and arrange the monitors, won't bring the monitors flush against each other.

Any suggestions about how I can get rid of this dead zone so the desktops are flush?

I've got a single Sapphire Toxic 5950 card.

Thanks!!

yoyoyo ...

for future reference, I installed the Catalyst Control Center

$ sudo aptitude install fglrx

The catalyst control center now appeared in my LM control center, but I wasn't able to start it as su, so I went to terminal again:

$ sudo amdcccle

And I was able to tweak the monitors until they're perfect. For future reference!!

You are probably using a HDMI adapter on that monitor, and it was under-scanning.

Actually, I've got a triple-monitor setup, 2 hdmi, and one displayport. I'm guessing it was the displayport.

Thanks
