Having real trouble with a new Mini-displayport to VGA adapter (active) [http://www.newegg.com/Product/Product.aspx?Item=N82E16882203129] that I'm trying to use to connect a third monitor with.
Setup is as follows. I have a Radeon 6970 video card with two mdp's and one DVI port. I have three 24" samsung LED monitors that run at a native 1920x1200. I need this adapter to connect screen three to mdp 2 so I can use the remaining DVI port on screen three for other devices (Xbox, PS3, etc).
I have had this set up and working perfectly where I've run the three screens on the DVI ports with DVI and mdp-DVI-D cables/adapters. It seems the mdp-to-VGA adapter should work here, given the relatively low resolution of 1920x1200, that the adapter claims to support it and I read of others using it for this purpose.
My problem is screen two, when connected in this fashion, reports as a 'Generic non-pnp monitor'. This limits the monitor to 1600x1200.
I have tried to manually install its driver - this didn't help. I've tried unplugging the power cable for 5 minutes (as some recommend), to no avail. I've tried unplugging and replugging the mdp-VGA cable with the monitor off and on, again to no avail.
I'm out of options and about to give up. Any advice would be much appreciated.
