Forcing PAL 50hz display with ATI mobility Radeon X1600

Tony Landais · 03 June 2008, 09:20

I own an Intel Mac Book Pro with an ATI mobility Radeon x1600 with dual boot Mac OS X and Windows XP.
I connected my TV via a DVI-Svideo link and I can easily choose between 60 Hz or 50Hz on the mac side.
On windows side I only get 60 Hz. My TV is correctly detected but I can't force 50Hz.

So here is my question how can I recreate the "mac" PAL 50Hz resolution in Windows.

It seems Powerstrip is able to create custom resolution and timing but I have no idea how to set it up.

Did anybody tried it before?

PS:I am using the latest catalyst drivers and windows update....

I found this web page

and used this setup for powerstrip

720x576 50hz (PAL)
PowerStrip timing parameters:
720x576=720,42,72,134,576,3,28,18,15125,41

it was a bloody nightmare but it works fine.

Now I am having an issue with the Sync in WinUAE.
I keep having a line parsing the screen from top to bottom.
I am not sure where it comes my driver, or WinUAE.
But I have a doubt about WinUAE since the LED Display keep changing between 50Hz and 51Hz.

Any suggestion?
