Kona LHe, MASSIVE video drift!

[Bob Pierce]

The solution for me was to change the output (in audio visual settings) to Kona 8 bit, rather than the 10 bit as used by the default Kona easy setup. This solves the problem for me, and as far as I can tell has no negative effect on image quality. I created custom easy setups so I don’t have to change it every time I change the setup. Hope this helps.

Hey all,

I know this is a few months on, but if anyone else is having this problem on newer Mac Pros (post expansion slot utility), the Kona LHe MUST be in either PCIe slot 1 or 2.

I was having seriously annoying sync and drift issues after getting a new Mac Pro* and realized I had installed the card in slot 3. Once I swapped it into slot 2, everything is running perfectly.

I was worried that Mountain Lion killed the Kona LHe or FCP 7.03, but everything is running smooth as butter (except for banding on my 23 in cinema display, but I don’t really care cause my Flanders Scientific LM-1760W looks so beautiful it hurts..)
