I have an ATI Radeon HD 5700 series video card. I have three 23 inch wide acer monitors hooked up to it. For months, things have been great and then all of the sudden for no reason, my third monitor turns off, windows picks it up as a generic Non-PnP monitor and I get this message from windows saying that there is a display link failure.

I have tried

1. unpluging the computer from all power for 10 min

2. reinstalling the drivers

3. rolling back the drivers

4. changing the color management properties

There were times that all I had to to was unplug the monitor from the display port and plug it back in and that would fix it. but then after a while it would just go down again.

I saw on another site somewhere that there is a 3 in 1 hdmi to display port adapter where you can plug all three monitors into the one display port. I can't find where to buy that piece or if my video card is compatible with it. Do you have any information on that?
