Today i've got an ATI 9550 Card.

Now I can change my resolution with "Graphics Mode" up to 1280x1024x32!

But i can't change the refreshrate! My refreshrate is still 60 Hz.

 

The reason is the VESA 2 mode ...

 

Now i want to get a ATI Card that runs with 1280x1024x32 an 85 Hz!

 

Can you tell me wich card a have to buy?

hmm weird...

 

i ve got a 9800 pro vesa 3 but it still only offers 1024 screen resolution, i guess i'll have to change that manually then...

 

i guess any monitor younger than 3y should manage a 85hz refresh rate at that resolution? u have a crt or a lcd monitor?

I confirm 9600 and above are only vesa2.

 

Another way that i made with my radeon 7500 was to flash the bios of the card

to initialize it at 85 Hz instead 60 hz for a specified résolution, so osx boot up with 85 hz refresh rate

natively.

 

does someone knows if the bios of the radeon 9550

can be edited/flashed to increase the refresh rate : for example :

 

1024x768x32 @60hz -> 85 hz

1280x1024x32 @60 hz -> 75 hz

 

I just find a sapphire radeon 9550 and can test it for 8 days before to buy or return to shop !!!

 

Thanks a lot.

Please check if 9550 lets monitor enter standby mode.

 

Thanks
