Can’t get 24″ Display higher than 30Hz with HDLink + Decklink HD Extreme
I’m using a Decklink HD Extreme card and have it plugged into the HDLink box. I’ve plugged my 23″ Apple Cinema Display into the HDLink DVI port, and as soon as I turned it all on, the monitor won’t sync to anything higher than 30Hz with the 1920×1080, resulting in a horrible flashing display. It looks like it is trying to display an interlaced image and not quite making it.
I installed the Decklink card correctly, installed the software, followed the wiring guidelines and plugged in the proper wire, updated the HDLink utility to 2.3.1, set it all up and am able to have FCP talk to the monitor, but I can’t get it to display properly at all.
Any ideas?

There isn’t any setting higher than 30hz when you’re in 1080. It’s basically no good as a desktop monitor because the refresh rate is so bad (it looks jerky and interlaced if you drag windows around). All it’s good for is displaying HD video.
Also you might be seeing the HDlink lose the PsF order… if you’re feeding it HD video and it’s looks all interlaced… just unplug the HDlink power and plug it back in – should lock to the sequencing.

Disregard the previous error. I had to reseat the card in the PCI slot. Is it just me or does the new Mac Pro card seating bar leave the top slot relatively loose after being screwed in?

The new MacPro seating bar is crap if you ask me. And yes, despite torquing it down, the cards still “float” around. I’m tempted to get rid of it and use plain old screws like most other computers!
