When the computer is in use it works great. The power option is set to High Performance so the computer is never put to sleep but the monitors turn off after 15 minutes. When they get turned off they immediately show the Cable Not Connected message until the computer is used again.

 

The computer is running Windows 7 Professional with a Nvidia GeForce 8400GS video card. The card is using the factory adapter to connect two Acer V223w monitors via DVI cables. I have verified that the drivers are the current version. I think it is a monitor setting but I haven't found any way to adjust it.

Hello,
 
May I first ask - do the monitors turn off after exactly 15 minutes? If it exact value than, most likely, it is a timer setting somewhere. But if not you can try going to Bios and reset everything to default by selecting the optimal setting in the bios.
 
If that doesn't work try to get a spare monitor and see if the same happens... If not than just search around the monitors settings. 
 
Feel free to ask any questions and I hope this was helpful, Citizen_WD

The monitors stop displaying after 15 minutes but the cable not connected message never goes away. I have been in the handful of settings in the monitor but haven't seen anything useful. I think that when Windows stops sending the video signal the monitors don't know what to do.
