Yes, both combinations; dual DP monitors are fine, dual DVI monitors are not working.

(Nor does 1 DVI screen alone on the HUB)

Label says A2-2 1 FW:0.45

RoyalKing: Yes, the Dell display via the DVI adapter->DVI works just fine.

We also tried only having only one of the Samsung screens connected which gave the same error.

Finally we tried an antique Dell 2007WFP from god knows when, much older than the Samsung screens and that didn’t work either, when using the native 1650×1080 resolution. Setting the resolution to a lower one, just for the sake of testing, gives image but like we first saw on the Samsung as well, the image is not aligned to the actual screen boundaries.

Paul,

Graphics card: NVIDIA Quadro K620

The original graphics driver was from December 2014 so we tried updating to the version above, without any change.

Hub: Multi Stream Transport (MST) Hub DisplayPort 1-2, CSV-5200 MST 1-2 DP Hub

Display/screens/setup:
Graphics card->DP->Hub
1 x Dell UltraSharp U2412M (Hub->DP)
1 x Samsung SyncMaster 2443BW 24″ (Graphics card->DVI)
1 x Samsung SyncMaster 2443BW 24″ (Hub->DVI-adapter->DVI)

All set at 1920×1200 resolution.

DVI-Adapter: Dell-adapter provided with the computer – model number DANARBC084. The DP connector of this one has a “DP++” logo on it, if that’s interesting:

We also tried an older DP connector with same result:
