David K how exactly was it that they were able to identify your card as not an S model?
I just got an E1 off ebay and it's only capturing in black and white. It takes screenshots in color so not sure what's going on.
I'm using a single link DVI cable. Could that be the source of my issue?
No, it only needs a single-link cable. Are you converting from another signal format? What about the Datapath software, does it show in color or black and white there?
This seller is still listing about one RGB-E1 per day on Ebay, like this: http://www.ebay.com/itm/391405969104 . The last three have gone for right around $70. As long as you've got a spare PCIe 4x or better, this can't be touched. There's no way to get another 1080p60 capable capture card anywhere close to this price.
