This question already has an answer here:

I I have a dual-screen setup with my laptop (1366x768) and an external monitor connected through HDMI (primary 1920x1080).

I don't know if this is cause by different aspect ratios (16:10 on laptop, 16:9 on external monitor) but Unity appears cropped approximately as shown in this picture:

enter image description here

If I use a lower resolution (1680x1050, 16:10) the desktop is correctly displayed, but those extra pixels could be handy.

So is this any limitation/bug on Unity? How can I make it display the desktop correctly at 1920x1080 pixels?

In case it could help, output of xrandr command.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

for completeness' sake: do you have Unity's Launcher set to only be shown on your primary (laptop) monitor -- and not on the external monitor? – nutty about natty Apr 2 '13 at 18:03
The launcher is shown on both screens. – Salem Apr 2 '13 at 18:14
...which is what you want ( ...and what you wouldn't want to trade-in for an uncropped primary monitor) ? – nutty about natty Apr 2 '13 at 18:48
Even if I make the launcher appear in only one screen the external one is still cropped (I can't see no window controls or scroolbar, when maximized). – Salem Apr 2 '13 at 19:14
Are you using NVIDIA ? if so, see… and… – nutty about natty Apr 3 '13 at 6:34

See HDMI/VGA connection cuts borders of screen or creates blurry text (Unfocused for just seconds) (and also Edges of screen cut off in Ubuntu 12.04):

NOTE (Comment made by User James - For some Samsung LCD TVs. Using the TV Remote Control go to Options -> Picture Options and set the Picture Option to "Fit to Screen".

Hope this helps.
