We just setup 6 M910q's at a client's site, and we're having so many problems getting anything on the monitors. They are older Samsung monitors, but not all the same. We've also tried a Dell and an Acer monitor. All the monitors have DV-I and VGA inputs, no DP or HDMI. We've tried different DP to VGA and DP to DV-I adapters, and all with the same result. 3 of the 6 machines were working with the DP to VGA adapters connected to the DP port closest to the power connector. When we tried to conenct a second DP to DV-I or even DP to VGA adapter to the next DP port, we either got no signal at the monitor, or the monitor would come on, flash lines of black, then lose the signal. It just cycled through that sequence. When we tried the third DP port, no signal at all on the monitors. Like I said, this was happening on 6 different M910q's, about 10 different adapters (different brands, active and passive), and 5 different monitors. We then plugged the non-working setup from the second DP to the first DP, the monitor came on with a signal. At my desk when I setup the computers, I have an older Dell monitor with only VGA and DV-I, and I had no problems with a signal. My monitor never lost the signal.
Has anyone else encountered this, and if so, is there any working fix short of telling the client they need to purchase new monitors? We have USB to VGA adapters on them at the moment, which work fine, but that is by no means a fix. Just a temporary band-aid.
Any suggestions would be great.

Unfortuntely, I have not. I've not found any solutions, so I've been using a USB to DVI or USB to VGA adapter when I encounter this. It's not a fix because it doesn't work outside of Windows, but it's a band-aid.
