Dear All,

Recently I bought Multi Stream Transport (MST) Hub DisplayPort™ 1.2 Dual Monitor. I was planning to set triple (3) monitors with the following specification:

PC:

• Dell Precision T5810
• Intel Xeon 2.8 Ghz
• RAM 16 GB
• Windows 7 Pro – 64 Bit
• GPU: NVIDIA Quadro K620 with input: 1 DP 1.2 and 1 DVI-I

Monitors:

• 1st Monitor: Eizo 27″ Flexscan EV2750 (Res: 2560 x 1440)
• 2nd Monitor: DELL 1703 FP (Res: 1280×1024)
• 3rd Monitor: DELL E228WFP (Res: 1680×1050)

I connected the 1st Monitor to directly to the GPU using DVI-I and 2nd and 3rd Monitors (via adapter DVI-to DP) to the 3d Club MST Hub. 2 monitors which are connected to the 3d Club MST Hub can’t be detected and only 1 monitor can only be detected which is Eizo 27″.

Then I changed the configuration, 2nd Monitor I connected to the GPU via DVI-I and 1st and 3rd Monitor I connected to the Hub using adapter DVI-I to Displayport. All of the 3 monitors was able recognized by the Windows and NVIDIA software. But 1 monitor connected to the Hub which is DELL showed only blank screen.

Then I changed again the configuration, I kept the EIizo monitor connected to the hub (working well), and I changed one of the DELL Monitors connected to the GPU and connected to the Hub. Again, all 3 monitors are recognized by the Windows and GPU. But only 1 DELL Monitor which is connected to the Hub showed blank screen (Black).

If you have any experience or idea about this problem please let me know. Thank you.
