DisplayPort on RadeonHD5770 on 10.7.2, possible ?

[sollarman]

Hi guys! I have been reading various topics and forums and still can't make the DP port on Sapphire 5770 to work on 10.7.2.
I use Hoolock FB, and did try Langur and all others and monitor (HP ZR24W) is detected properly, but screen stays black no matter what.
I guess, that Apple just blocked DP functionality in Lion on non Apple's cards ?

I don't know how to fix your problem, but I did have a MSI 5770 running in Lion with a working DP port...

Are you using a DP active or passive adapter? With passive I guess it won't work.

no longer using a 5770

Actually I use straight DP port, without any converters. No luck for me so far

I had the same problem. With GraphicsEnabler=No my DP worked well, with GraphicsEnabler=Yes it only worked with my DVI populated.
