I recently Got a Hauppage Colossus capture card inside a pc from an estate sale. I put it in my main computer thinking i could use it to capture video from another pc. I installed the drivers and the capture software from hauppage Website and I launch the Capture software the card is detected but it says no HDMI signal and other pc is plugged in and on. I have also tried arcsoft Showbiz and it says the device is not available or being used by another application. Ive tried closing and even uninstalling any software that could possibly be using the card and still the same thing. I have anything plugged in however im using A VGA to HDMI adapter which is plugged in the back of the pc i want to capture video from. Can I even use This card to capture video from a different pc. And if so could someone tell me what im doing wrong?
