Calibrating an AJA KonaHi connected HDTV
on Nov 18, 2012 at 3:14:56 am

I just started a new position in tele-production and am working on a mac pro that is connected to an HDTV through a KonaHi card. I cannot figure out how to calibrate the television as I'm new to this whole broadcast deal and Kona cards in general, so forgive me :P

I read somewhere that I need to use the color bars in FCP7 to calibrate it by eye, but there must be a better way since it doesn't show up in the Display settings in System Preference. Am I able to use a Spyder or some other sort of calibration software to recognize the television?

Thanks again as I'm new to this whole thing.

Jake

The calibration is listed in the FCP7 manual.

Why would you assume that a TV connected to a video card would show up in the display settings?
Video is not a bi-directional communication and other than the HDCP security in the HDMI port,that keeps copyrighted content from being recorded there is no communication between the computer and a monitor over a video connection.

I was only presuming this due to the fact that when any display is plugged into any native video card port of a computer, it will show up in the display settings.

Example: I can plug in any TV/computer display into a DVI/mini Display on a Mac or use an adapter and it will show up in my display settings just fine. That's common sense in my book.

Am I correct then in understanding that since the AJA is a third party card it does not directly communicate with the computer's native video signal?

Ideally I am wanting to calibrate the HDTV using a datacolor Spyder, but the software doesn't recognize the television due to the above situation. Of course it recognizes my display thats plugging into the mini Display Port, but I don't understand at all how to have it recognize the AJA card, which is outputting to Component on the television. Perhaps it's not meant to at all.

I know that calibration by eye is subjective, but I'm trying to learn how to achieve it by using software and a proper calibrator.
