My system: Ubuntu 12.04 LTS. My graphic card: nVidia GeForce gt430. My monitor is Samsung LE26R51B. And my connection is digital (HDMI).  

The current screen resolution is not good at all, I can't see the top bar and the left one.

Here are the available resolutions in settings:

```
1920*1080
1280*720
960*600  
and lower resolutions

```

But with no one of these I can see the top bar in it. They are bigger than the monitor.

In Windows 7 I use **1202\*670** resolution. 

**How can I change the resolution to what I want exactly?**
