im using an Motherboard ga880gm-ud2h (internal grafic card disabled) with one Radeon HD 6870 with 3 units Startech Displayport USB 3.0 card
im trying Resolume arena 5.0.0 and 5.0.1, with windows 7 and windows 10 int he same PC and i get the sam problem.
The outputs of Startech Displayport USB 3.0 cards, at beguinning are all freezing in black frame, they dont shows nothing until i move the "Advanced" window screen to the startech Displayport USB 3.0 screens, then they start working when each monitor screen output "feel" the "Advanced" windows screen . If i move the window to the principal monitor again, thy freeze again until i move the "Advanced" window again in the startech Displayport USB 3.0 outputs screens.
If i remove it , the motherboard internal grafic card works well with startech Displayport USB 3.0!!!
i tested selecting Aero Windows theme mode, and i nothing, i dont know what to do more =(
Please check the picture with the videos output freeze
many many thanks!
