display problem after 10.5.7 update

[progginRay]

Hi people,

I use a 1920x1200 display on my mac mini, 1.66 GHz Core Duo, first revision.

After the update it seems like the mac tries to tread the monitor as if it were a tv.
In the display settings 1920x1080 is the highest resolution available, only framerates of 50 Hz (PAL) and 60 Hz (ntsc) is available (equal to what resolution you set the system).
On the display the desktop is shrinked down to about 90% of display size and has a slight error in aspect (circles are no circles anymore). Also the color profiles are terribly misinterprated, gamma is wrong and everything is overly colored as if it were windows.

Any advise is highly appreciated as I'm having a hard time even reading any text.


Thanks in davance

Looks like some good tips here - http://www.macfixit.com/article.php?story=20090512221023108

You should also try reinstalling 10.5.7 update, using the downloaded combined 10.5.7 updater from the Apple web site.

The combined updater is well-known to often fix minor issues that begin after doing a Software Update.

after creating a custom resolution in SwitchResX and making it the used one, 1920x1200 was back in the monitor pane. Lots of restarts required though.

If you wanna see a really weirdly tiled screen, set it 1920x1200 @ 50 Hz. ;-)
