I have not tried going into the bios with it hooked up to the desktop pc. I did not change any settings on it, it just showed the desktop on both the laptop screen and asus monitor. And just to clarify something, when hooked up to the laptop, it works fine. Yes the desktop recognizes both monitors. If the monitor is going bad, why would it work on a laptop? My main 24' monitor has no issues at all on the desktop which makes me think it's not the video card I hooked this monitor up to a laptop via vga cable and it never shut off but it still flickers. I have also tried using a dvi cable since this monitor does have a dvi connection and the same thing happens.
I am using a vga cable for this and am using a dvi to vga adapter hooked up to the video card.
When I go into the display settings, if I change the resolution, it will come back on but just for a few seconds and shuts off again.
I am using an AMD HD5870 video card and tried reinstalling drivers with no luck. Before it shuts off, it will start to flicker. It will come on but shuts off after about 15 seconds or so and the power light stays blue, doesn't turn yellow like it's going into sleep mode. I use this as a secondary monitor on a desktop and it will not stay on. I have an Asus 19' VW193 monitor and having issues with it.
