Ok so I thought that 10.5.7 might have addressed this, as I was lucky enough not to see it all last night and today. However the issues seems to have popped up again. I'm getting an issue where I get gray pixelated noise from one of my displays after the mac pro sleeps. After looking around earlier this week I found a few things that seemed to point to people with Macbook Pro's having this issue under the following conditions: It happens after OSX sleeps the displays most of the time It seems to involve the mini-displayport to dvi adapter (others of tested the monoprice one with limited success.) It happens with non-apple displays, I have a 24" Dell 2407WFP, in fact I have 2, and the DVI connected one doesnt have this issue. Unlike other people that seemingly have to restart to get the display to get the correct signal. I however havent needed to do that, when it started to happen it seemed to correct itself after a few seconds. Now though it hangs until I sleep the displays again and unsleep them, through an Expose corner. Has anyone had this problem on their new Mac Pros with the Nvidia GT 120? Is it card related regarding the adapter? As I was thinking to get either the 285 or the HD 4870 at somepoint. If anyone has any thoughts it would be appreciated. It doesnt happen all the time right now, and isnt really consistent so I'm trying to figure out if something is faulty, but that doesnt seem to be the case.
