I need to record a computer monitor display digitally. Normally I would install software or a DVR card on the home computer but in this case the computer is used clinically and I will not be able to modify it. What I can do is split the output coming from the home computer. Are there any DVRs that take VGA as an input? Alternatively, is there a way to use the VGA signal as an input into a com port in another computer where I could use a DVR card? Thanks for any information you can provide.
