Two monitors behave weird when started from Sleep
Hello all,
I have a MacMini 3.1, 2.26GHz Core2Duo, 6Gb RAM, OS X 10.8.2, NVIDIA GeForce9400 256 Mb.
Initially the MAC has use one LG LCD 17" wide monitor. Recently I bought a 19" Philips LCD monitor.
At this time I have two monitors connected on it. One LG LCD 17" wide and a Philips 19". The Philips is connected using MiniDVI2VGA adapter, the LG is connected using MiniDisplay2VGA adapter. Both are working perfect. However, everytime I start computer from Sleep, the LG is loosing its settings. The system no longer recognize it. When I go to Display, instead of seing it as W190 it is showing that is a VGA display. None of the resolutions listed are the one my LG is using (1440x900). The closest is 1440x1050. The background also dissapears showing me the one of the system's background. The only way I can make it to look correctly is shuting down the computer and then restarting it. I tried:
1. Log out then log in. No results.
2. Restart in SafeMode.
3. SMC and PRAM reset.
4. I installed Onyx and did a full automated cleaning operation.
None of the above worked.
The only way to make it working is to reboot. No restart. Just Shut down then Start.
