In Topic: How to: ATI 4850 working on SL

15 March 2010 - 12:17 PM

first off, try booting with the -x (safe mode) to see if you can get that far... then you can try some of the ideas/options in this thread.

I am troubleshooting my Powercolor HD4850 at the moment and have had some success.. refer above.

EDIT - All tests done hot swap and reboot.

So to summarise

Upper port - DVI>VGA adapter gives max res of 1600x1200 and QE/CI (It seems the DVI>VGA adaptor kills the WS resolution support for some reason)
Upper port - DVI>DVI gives max res of 1920x1080 and QE/CI
Lower port - DVI>VGA adapter gives max res of 1920x1080 and QE/CI (if you boot on top port and hot swap to lower adapter gives "noise" and also stops my monitor from switching back to the DVI input for some reason )
Lower port - DVI>DVI gives max res of 1920x1080 and QE/CI

I'd call that SUCCESS! :smoke: :thumbsup_anim:

Hi, Richdave, did you ever try to launch iMovie? I have a PowerColor HD4850 too. I followed your procedure and got working screen res. as yours. Except one thing, when I launched iMovie, I got an error that indicated my card lacked QE support. What a pity....

Did you ever try to connect the Monitor via D-sub, instead of DVI? As I remember, I had the same problem a couple of weeks ago. Because I had experience on D-Sub, DVI, HDMI problem in my other Hacintosh, I tried to connect the Monitor through D-sub to let OSX "recognize and remember" my Monitor. Then I re-connected the Monitor using DVI and everything became OK. Hope this will help!
