[wo-yo]

PB 1.67 last PPC generation connected to Dell LCD 2407 over DVI produce blurred picture.
Resolution is set to 1920x1200 in mirror and extended mode.

Picture also isn't stable it has some flickering effect.

Does anyone have experience with this combination?

I am the same exact problem! I have been looking for a fix for this issue for a while. I am using the new e207wfp I think, or the new 20" with a Powerbook 1.67 15" 2nd last revision(non hd screen). When I connect to dvi i also have that flickering effect. When i connect with vga, it works fine and dandy.

I have a feeling it is the GPU and the cpu not working well together that is causing the problem. I used openGl(its in the developers package) and whenever the CPU wait time spikes over a certain point, the screen flickers to black for no more than one or two seconds.

I think it may be a driver issue for the radeon 9700 128 mb card.

Hopefully someone else can give a more definitive answer to this issue.
