Hi,
check if the display driver is installed or not in your computer, here is the step to check the display driver is installed or not,
step 1. go to start and select control panel.
step 2. double click on system.
step 3. after this a window pop up select hardware.
step 4. click the device manager and after this another window pop up.
step 5. in this window you can display adapter on 4th row.
if you cant see this display adapter row so you can see something with ? sign in other rows and you can see vga adapter or display adapter down there. if you see ? sign that mean this driver is not loaded you need to load the driver for your display driver. there is no problem in your LCD monitor.
