Secondary display does not show complete screen
I have Ubuntu 14.04, and am seeing an issue with my secondary display.
For some reason, it seems that on all 4 sides of the display, there are regions I cannot see. The picture stretches the entire screen but it's like it's zoomed into the center a bit, and I lose about the height of a title bar.
If I maximize something on the screen, it will maximize into these regions, so that, for instance, the top title bar of the window will be hidden from me.
I tried taking a screenshot for this issue, but it shows nothing out of the ordinary. So to demonstrate, I decided to manually resize my browser window (right side) to the corners of my visibility. Any further and I cannot see it.
The monitor in question is connected via HDMI if that makes any difference.
Oh, and I primarily use GNOME, but I see the same issue in Unity and GNOME2.

Go to System Settyngs : Hardware : Display, and select the screen which is you need to turn it off.
Hope this helps,
2Maybe the resolution isn't correct for that monitor, if you try changing resolution in the Display settings mentioned earlier does that do anything?
(Or xrandr has more options for changing the displays, maybe something in there would help)
If you have a TV connected via HDMI, it may be that the “zoom/aspect-ratio” setting is wrong or that the TV just doesn't support “dot for dot” input, which is often the case with TVs more than a few years old.
My current TV has a button on the remote that you push to switch from 16:9 (“Full”) to 4:5 (“Normal”); it also has two zoom levels and “PC Mode” that makes the TV behave like a 1920x1080 monitor.
However, my previous TV had no such “PC Mode” and the top 20 pixels or so of the computer display would be off-screen on the TV no matter what setting I used, just enough that I could only see one or two pixels of the bottom of the menu bar. If you had a DVD player connected via HDMI, you'd never notice the little bit missing from video playback, but for a computer desktop display it is essential that you see every pixel.
