Hi there !

First of all, please excuse my english, I know it's poor :)

I tried to setup HD4850 drivers under 10.5.7 (iAtkos) using lastet Natit from netkas. After reboot, my screen looses signal, on each graphic outputs (VGA, DVI, and HDMI). I have a PowerColor ATI HD4850 512ddr3.
I can boot under a clean install of 10.5.7 and get basic 1024*768 resolution, but none of the solutions explained of the forum worked for me.

I know this problem is common one, so I would appreciate if someone could help me to get it working :)

I got these cables:
- DVI male => DVI male
- HDMI male => DVI male
- VGA male => VGA male

I don't have any DVI => VGA or something like that.

Have a nice evening,

Same thing here mate, but with an HD4850 Sapphire 1gb DDR3.

Got DVI, HDMI and VGA ports.

Nothing works, neither with EFI strings.

And NO ONE cares, i wish you have more luck than me. I Made a lenghty post about my problem and no one even bothered reading it.

Heres the 3d: http://www.insanelymac.com/forum/index.php...p;#entry1240220

That's very sad. I think lots of people have the same problem but don't bother making a post.
Please if someone knows the solution, tell us !
