I take it that you have a dual link DVI port on your monitor. That means that your monitor runs at more than 2000x1200 @ 60 Hz.
No, they're plain full HD 1920×1080.
The 1920×1200 uses the DVI output on the same card.
So, 1 GPU, 3 monitors: 1920×1200 via DVI, 1920×1080 via HDMI, and ... passive DP->DVI will not run any of them.
Hence, a 3rd GPU with DVI.
The built-in GPU with DP and HDMI isn't used, since I couldn't get it to work with a discrete one.
All this may be partially due to failures on my part, but I did buy a $40 *active* DP->DVI and that did work, but I returned it because $40 for a 3rd monitor wasn't prudent.
Which GPU is this? After all passive adapters only work with DP++ ports not DP ports. Not all GPUs have DP++ ports. -- Len Sorensen
