Hi! I have the following problem: I use Catalyst 5 (4): <configuration with two video cards NVIDIA GeForce GTX 650 Ti (basic) and NVIDIA GeForce GT 630 (optional)>. Instead, images from the video input, I use the card Blackmagic Intensity PRO defense, on the second monitor connected to an additional graphic card shows a white square. The main monitor - all right. Video files are played on both monitors normally. How can I fix this?
