Hi,

I think your Display monitor cable damage, or may be your motherboard display cheap damage, or your display driver problem create.

First of all you check your display driver or reinstall driver. Sec think used external VGA card or check it. If not solved then your monitor display section damage. So contact good monitor technician.



Thanks..

Do this to check if your monitor is in working state or not...!

Step 1:- Turn on your computer.
Step 2:- Unplug the Video Cable of your monitor which is connected with the computer.

( Video cable:- Cable going from the back of your monitor to the back of your tower. It has a plug with two screws on the plug ends, which you can unscrew to unplug it. Thats how it looks like. Some times it is in grey in color some times in blue.)

Step 3:- Now check on your monitor. If the display says " No Input Signal " :- your monitor is fine. Some thing wrong with the computer graphics.
If there is not display and the monitor light is blinking or solid the monitor has gone bad.

( Note :- Remember when you unplug the video cable do not unplug the power cable of the monitor. )

Let me know if it helps.

Replace the entire DAC board (board with power suplly going into it) for easiest solution.

i have solve the problem for my hp nx7300. mine used to show everything that should be shown on the screen but had the screen placed in a Conner so small. i solved this by uninstalling the monitor and unknown device drivers. i have then installed the unknown device as a blue-tooth adapter to avoid this problem recurring. hope this sorts out some people's problem. the other half screen with half completely not shown has to do with the cable connecting the monitor and the CPU. remember solving this for my friend by cleaning the connection port.
