Hello and thanks in advance for your help.
-I have a Surface Pro4 64 bit.
-I have three Samsung Monitor that are connect to the UD3900
-Monitor 1 connects with a DVI to the DVI port
-Monitor 2 and 3 use the Arkview USB 1612 to connect DVI to USB to the port
Everything works fine but as I just bought the 4k Samsung and plugged it into the UD 3900 and can get no picture. Using an older samsun TV everything works fine.
I have done the clean uninstall and reinstall that you have recommended in other posts. I am at a lost. The TV simply says no source detect. Yes I have also tried with another HDMI cable that does not help.
