[New Found!]
1. When I set to others instead of 1440x900 (16:10) or 1280x800 (16:10) revolutions,
the black bar must disappear.
2. When I set to 1440x900 revolution, the black bar must exist.
The display area is not fit to my monitor(1440x900) and there is a black bar at the top of my screen. The bottom of the display area can't be displayed. How can I deal with this problem?
I wonder if the problem come from the lack of display card (MSI R4770 Cyclone) driver but I don't know how to install it. Do I need to install it?

Anyone can help me solve this problem?
Thank you for your attention =]
Sometimes the monitor itself requires some vertical/horizontal alignment via the buttons on the monitor (if it is a separate monitor); often there is an auto adjust button also that should do that for you.
Otherwise if this is not the problem, could you go into the terminal (
CTRL + ALT + T
) and typexrandr
then press enter, and post the output here, and also the contents of the file/etc/X11/xorg.conf
to give an idea of the configuration of your displays.Looks like you'll have to adjust the vertical image offset of your monitor.
Your monitor should have some control buttons with menu options like brightness, contrast and image control among others. Search for the buttons around the edges of your monitor case; in mine it's alongside the power button.
With the menu button, select the image control/image adjust under which you'd find menus like auto adjust, horizontal position, vertical position, ...
Select vertical position and use the menu buttons (+,-) to adjust the vertical offset.
Checking your monitor's manual for details on your monitor settings might help.
Editing the monitor's configuration file may help - In your home directory, run:
gedit .config/monitors.xml
and see if changing the resolution helps.
To find if your graphics card has a driver, run this:
lshw -c display
and look for something like:
configuration: driver=radeon latency=0
This is also possible by running:
lspci -v
and looking for:
Kernel driver in use: radeon
under
VGA compatible controller: ...
If you find anything, you could add the info to your question.
Use the following setting can solve the problem. (turn off the second monitor)
