I'm still struggling to get a second monitor on the Poweredge 840 because there's no way I can find to disable the onboard vga. So, I'm looking at a usb to vga adapter. Trouble is, the second monitor is to display video from the Premier Pro timeline, so I suspect a usb-vga converter is not going to handle the motion. I suppose I could switch the displays, so the onboard vga handles the display but I have heard that the converters can have an adverse affect on the existing output.
Does anyone have any experience with this. Might usb 3.0 be the answer?
