yes youre correct...my mistake. youwould have to play with color settings on the graphics card inself. This obviously wouldnt work for apple tvs. either way im still unsure of the filtering and converting to current as the ULN 200 darlington pair should take the analog voltage just fine. Maybe use the op amp as a buffer...or opto isolate the signal from the transistor. still seems like a cheap and quick way to produce this same effect...albeit if you have a dual video card setup
