Hello! I have a fairly aggravating issue. So, I recently had to replace my monitors because one blew up (it was old and the CCFL just exploded). Right, so I look at my options and get a couple of monitors. I look at the outputs of my GPU and decide to use the Displayport 1.2 output. Since, the monitors I purchased don't support daisy chaining I figure I'll go out and purchase a MST Hub so I can run two monitors from the same port. All is mostly well when I initially connect them up. Typical stuff like Windows being dumb happen. At any rate about 15 min later I get it all working and life is wonderful! Two monitors off of one port. I go to restart my computer and then that is when I encounter my aggravating issue. I get nothing on either display. Windows login comes up. I get nothing on the display. I login to Windows with a black screen. I still get nothing. The only way I get something is by power cycling the MST hub. Then I have to give Windows a little bit to finally register that I have two displays. So, just to make sure it wasn't the displayport being messed up I hooked up a single monitor to the displayport and I have absolutely no issues. Works flawlessly. 

 

At this point I contact Nvidia support because the way I see it is an issue with the driver or BIOS of the GPU. They don't recommend the use of a hub. So, then what is the point of even selling hubs? Anyway, that is a topic for another day. So, here I am using the hub without an issue while Windows is up and running. However, restarting or basically anything happens where the displays get cut off from like sleep or turning off the displays, etc . . ., I have to power cycle the MST hub. I'm trying to figure out if I'm always going to have to do that because if I do then I'm just gonna return the MST hub and buy a couple of DVI to HDMI cables (monitors don't have DVI in). But I really cannot think of a reason why it shouldn't work unless I maybe have a defective MST hub, there is an issue with the GPU, or I'm doing something wrong. 

 

Specs for those curious:

i7 4770k

Asus GTX 780 DirectCUII (outputs are one DP 1.2 port, 2x DVI, and one HDMI)

2x HP Z23n (inputs are one DP 1.2, one VGA, and one HDMI)

Startech MSTDP123DP

 

Anybody got any ideas?
