Since when does the Indivision ECS have a digital output?
Sorry, I might have confused it with the MK2. In the instructions, it says if you have vertical lines present on your display, you need to go into the indivision utility where you set its modes, and disable DVI output and only enable VGA. I had that, so, that's what I did (since I was using it on a monitor that did not have a DVI input and used a DVI --> VGA adapter on it).
