Display Controller and Video mode
Display controller
The display controller interprets software commands into hardware 
commands that turn particular parts on the screen on or off.
The display controller also controls the video mode and uses industry 
standard rules to govern the screen resolution and the maximum number of 
colors that can be displayed at any one time. Therefore, software written for 
a given video mode will run on any computer that supports that mode.
Video mode
Video mode settings are configured via the Screen Resolution dialog.
To open the Screen Resolution dialog, click Start -> Control Panel -> 
Appearance and Personalization -> Display -> Change display 
settings
.
Due to the display panel’s increased resolution, lines may appear broken 
in when displaying images in full-screen text mode.
If you are running some applications (for example a 3D application or video 
playback and so on), you may see some disturbance, flickering or frame 
dropping on your screen.
If that occurs, adjust the resolution of display, lowering it until the screen is 
displayed properly. 
Disabling Windows Aero

 help correct this issue.
