Monitor works on laptop, not on desktop?
I'm hoping someone might have had this problem before and can tell what to do. I have a SHARP 19 in LCD monitor....I had been using it for the last 3 years. If I connect it to either my HP desktop or my Dell desktop, the screen comes on, but after about 8 seconds, it goes black...no picture. If I connect it to either of my Dell laptops, it works great. As a test, I hooked it up to an IBM laptop, and it works. The monitor used to work on my Dell and HP desktop.
