Detecting LCD monitors in WinXP systems

  
Many friends are asking me how to detect the LCD monitor in the WinXP system. In fact, it is very simple to test the display directly with the Windows operating system.
Click “Start”→“Run”, enter “command” (Windows 9X/Me operating system) or “cmd” (Windows NT/2000/XP operating system), this will open “Command prompts ” window, enter “debug” and press Enter, then there will be “?” or “-”, indicating that the debug program is running, press “Alt+Enter” >Maximize the window so that we can perform full-screen testing, and then directly enter
“F B800:00 F9F 20 70”full screen white,
“F B800:00 F9F 20 40”full screen red,
 F B800:00 F9F 20 20” full screen green,
“F B800:00 F9F 20 10” full screen blue.
In order to facilitate our viewing, you can also add a grid to the full screen color,
<quo;F B800:00 F9F C5 07 C4 07” full screen white grid,
“F B800:00 F9F C5 04 C4 04” full screen red grid,
“F B800:00 F9F C5 02 C4 02” full screen green grid,
“F B800:00 F9F C5 01 C4 01” full screen blue grid.
The above are the easiest way to detect the LCD display in WinXP system, and it is also the most direct!
