Having problems with your HP L1940T 19" LCD Monitor ?

Not The Bulb

\015 I don't think it is the lamp that is bad. The same thing happens to my monitor but the box that pops up says that there is no input connected although there is and the picture does show for a second or so before going off.\015

Answers :

The picture of no input goes off because monitors that do not recieve input go to sleep mode in an instant.

There are four possible causes. First, the cable is not firmly connected to either port, or the cable is damaged. Second, your graphics card could be damaged. Third, the resolution currently set for the machine could be set to a resolution that is too big for your monitor to support, or four, you could have switched your video input. You can change the video input from VGA to DVI and vice versa using the monitor's buttons. The input you want to recieve is from the VGA, though you are probably recieving DVI right now. Apart from that, I cannot help you further as you are not too specific with your information.
