We just purchased a Decklink HD Extreme 3d Plus card for use with Final Cut Pro and soon Davinci Resolve. We have a 42" OLED TV mounted above our Edit bay monitors for client reference that is hooked up through a 50 foot HDMI cable (our computer is located in a machine room across the hall from our suite). We where using a Matrox LE system before to feed the TV and there where no issues. But now with the Decklink Card, there is a strange color fringe that is causing a rainbow of colors to display across the image.
I've played around with settings on the drivers and nothing has changed. The only thing I can think of is maybe the cable run is too long? Anyone else experience this before?
