Hello to all. I own a powerbook 667DVI and I connect it ona second sony monitor (G220) on extended desktop mode. The problem is that only the default resolution of 1024X768 get the 85Hz treatment.All the other resolutions are on 75Hz. I'm guessing that somethings going on with OSX. On 10.1.4 I could get the monitor to display a higher resolution at 85Hz (at 1280X1024). But even then the menu was very weird. On 1152X768 for example I could only get 75Hz!!! And it was a smaller resolution than the 1280 one.Now on 10.2.2 I can't get beyond 75Hz on any resolution except 1024X768. What's the problem?? I disabled the recommended resolution by the monitor just in case but ofcourse I had no luck with this. So does anybody now the solution to this thing or why is this happening?
Thanks in advance for your answers.
