Sounds like driver related problem to me... use this software to update all of them: Driver Update Software for XP Vista 7 8 (especially monitor driver)

check for domed bulging capacitors on power board.use caution if you attempt to repair yourself.high voltage.

The Acer P191W is plug and play. Vista does not require a driver to use this monitor.

That can be the soldering joint at the lamp assembly is bad. It will cause the inverter circuits to go into shutdown mode. You should also inspect the power supply caps also.

Try reducing the screen resolution to 1/2 of what it is now!

I don't believe this monitor has speakers.

Try pressing the "Auto" button located by the power button. If that doesn't work, I have a few questions for you.

brianfh01, Hi, I'm louie12fix. Can't say we will be able to fix, but we can try some different things. Will P191W do same stuff if connected to different PC? Did it work (perform perfectly) one day, and then act like junk the next day? Did you check with ACER about warranty service?? Are you using this unit for business or home? Can you, or did you connect different monitor to the pc that the P191W was connected? I certainly would be trully ********** if a 4month old monitor didn't perform to specification. Did you buy it locally or online? If local, maybe the store will swap it out for you. Bye for now. Get back to me at louie12fix on fixya or lmistyrel @aim.com

Not sure what the problem is, but I would suggest pressing the Fn+F5? There is a function key that toggles from dual screen, just the laptop screen or just the monitor. Hope that helps..

G'luck
