I have a second monitor connected to my laptop.

It has been detected and i am able to click to extend the desktop to it or clone it, but when i apply the settings the second monitor flickers for a couple of seconds with the desktop on it before it goes blank.

I cannot figure out how to fix this problem. I have ati radeon hd 3200 and have tried to set up the monitor through the catalyst control centre aswell as through the display properties in windows but neither will work.

 Can anyone help me??

Try the fn hotkeys on your keyboard to switch the display. Usually fn + a key with a picture of a screen on it. Wait a couple of seconds between presses, some can take a while to click.

Is that a crt? longshot, but check the refresh rate specified in the display settings for that monitor, might be too high. Also check the resolution is within the monitor spec or just reduce to a minimum and see what happens.

Hi its a lcd monitor. i tried lowering the refresh rate to as low as it could go along with lowering the resolution to all available options but the same thing happens every time. I dont understand why the picture can come up before it blanks out..

Dows the monitor work on another PC? It could be a faulty screen - I have seen that behaviour a few times and it turned out to be the screen.

Hi i tried the monitor on another laptop and it wouldnt work, however it didnt even flicker with the image before going blank, just wouldnt show anything. The monitor was working fine on a desktop computer before though.

If trig42's suggestion doesn't pan out, try restarting with the monitor plugged in and enabled. Also remove from device manager and restart, you've probably done all that anyway.

Another long shot, when you have everything configured, disable the TMM. An even longer shot (possible weird graphics problem) disable aero.

Last try, get the official vga drivers for your laptop directly from HP. Most likely much earlier than the ones you are using.

yip tried doing all the solutions, i done some research and it turns out that alot of lcd monitors do this after awhile. looks to be like some sort of powerboard problem when they cut out after a couple of seconds, best to just get a new monitor as it would be cheaper.
Thanks for the quick responses ppl
