Mini Displayport problem with MacBook Pro - Static/interference

In between my MacBook to MacBook Pro transition, I had this problem where I sometimes would wake the computer and only get "snow" on my display (also did it on a different display I tried as well) and sometimes it would take a while for the picture to finally come on. Now, I bought a Displayport to Mini displayport cable, and I haven't had the issue since. So I'm guessing it had something to do with the Mini DVI adapter or the DVI cable I as using.

Your MacBook looks closed in this video. Did you know that they automatically go to sleep when closing them? I suspect you're simply not getting any video signal from the MacBook because it's closed. Try the test again with it opened.

I get video just fine on my Samsung SmartTV through the Mini DisplayPort to HDMI, but there are frequent disruptions in the signal and audio "popping". When the signal cuts on the TV, it's still present on the MacBook screen. (An issue with Mini DisplayPort?)

@starbase101 Wrong. When you close the lid, it does go to sleep, but if you have a keyboard, mouse, and monitor connected it puts the system in "clamshell" mode which allows you to disable your internal display and use all graphics power to drive the external monitor.

I also tried to install the new driver for this graphic card which is need to have Mac OS X 10.6.8 which I have and it gave me an error which is saying this plugin can not install on this computer... I tried different ways and links and I didn´t get any possively results....

@dameloya Call apple. Graphics processor could be bad.

If you get the ProShutdown app for the aluminium keyboard, you must make the monitor go asleep and then wake it up. The snow activity will disappear on the second monitor. I’m using the Mini DisplayPort to DVI adapter for my Dell monitor to my iMac i7....I still get the snow activity. I just ordered the Displayport to Mini displayport cable. Hopefully it will correct the problem and avoid the snow activity.

@Madtoe That software doesn't do anything to help the problem. All it does is allow you to bring up the diologe box that CTRL + EJECT brings up. Just wait for your displayport cable, it will fix the problem.

@Glovesave74SH Nope, I have the exact same problem. When I tried this on my gf old regular macbook it works perfect. I think it's the gfx card. Did you get it to work?

[Glovesave74SH]

Were you ever able to fix this? Because my MacBook Pro with a MiniDisplayPort to DVI adapter does this exact same thing on my 19" Viewsonic monitor. I'm almost positive that it has something to do with the adapter.

@sdschramm The cable as you suggested seems to work... DisplayPort to Mini DisplayPort

I need some feedback here.

thanks

I have an MacBookPro i7 2,8GHZ with a NDIVIA GeForce 330M GT and it is giving me lot of problems.
