OSX does not detect my LCD

[TPS]

Hi everyone!

 

I have just installed JaS 10.4.7 on my PC with the following config:

ASRock P4Dual-915GL

3.0GHz Intel P4

ATA HD

ATA CD/DVD

 

I have installed these patches:

- 10.4.7 upgrade for intel

- SSE3 Patch

- GMA900 patch

 

But Mac OS X does not detect my LCD display. That is, after the grey boot logo i get a blue screen for a short time and then the display says "input not supported". Actually the installer DVD did the same.

So right now I am using an old CRT display. It is possible for me to boot up with the CRT display, and then switch to the LCD display. But if I then click on the "detect displays" I get "input not supported".

 

The LCD display is a BlackView 17" 1280x1024.

 

Are there anybody how have an hint to what I can do?

 

Thanks in advance.
