Can two or more VGA2USB or DVI2USB devices can be used to capture VGA signals simultaneously?
• Yes. Epiphan Systems suggests that separate VGA2USB (or DVI2USB) application needs to be ran for each VGA2USB device attached. You will, however, notice a significant difference in frame rate for each additional active VGA2USB. The higher the performance of your computer, the better the possible frame rate. Our internal testing on a Dell Dimension 2400 (Celeron 2.4GHz processor, 512mb RAM) at 1024×768 with two VGA2USB (or DVI2USB) devices yielded average frame rates of 7.1 fps and 4 fps. In contrast, a Pentium 4, 3.0Ghz desktop with 512MB of RAM at 1024 x 768 yielded average frame rates of 9.52 fps and 5.85 fps. Please note that you must start the VGA2USB application after connecting each VGA2USB.
