Distorted Main Display but works on extended display

by beta_krys / March 1, 2011 3:40 PM PST

If I hook up my sony bravia tv to the vgi port on the laptop (for extended display), both my MAIN DISPLAY and the EXT DESKTOP work phenomenally. However, if I reboot the laptop (no matter in what order I disconnect the sony tv, before or after shutdown) as soon as the desktop comes up the picture is COMPLETELY DISTORTED! If I then connect the TV and reboot, it works fine.


This also happens if I try to "mirror displays." At that point I have to restart all the time.


OS: Mac OS/X 10.6.3
GPU: Intel GM965 / Intel

Distorted how?
by Jimmy Greystone / March 1, 2011 10:12 PM PST

Distorted how? There are several different possibilities that could all fall under the general category of "distorted". We're going to need more of a description of what exactly it looks like. Pictures would be even better. It would also be useful knowing exactly what model you have, because there hasn't been a VGA port on an Apple laptop in many many years. So we need to know if it's DVI, Mini-DVI, or Mini-DisplayPort. The model would allow us to look up the specs of that system and find out.

That's the problem

Well, There' is a VGA because it's a Gateway M-6750 formatted to GPT with mac os x 10.6.6 running on it. It's not actually a macbook. I'm running all intel core mac compatible components (aside from the GMA X3100 chipset). Theoretically, it should function identically.

The distortion appears as columns of oval color blocks. It only happens when I go from a cold boot.

And at this point, the thread stops

Installing OS X on a non-Apple machine is a violation of the Apple EULA and is not discussed on CNET's forums.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
