Currently Being ModeratedMar 20, 2009 9:47 PM (in response to chinhster)I am also seeing the colored static screen when my display wakes from sleep on my 2009 Mac Pro with 2x2.26 Quad-Core Xeon with the ATI Radeon HD 4870. I'm using a Gateway FHD2400 hooked up with a DVI cable to the Mac Pro's DVI out. Unlike your case, however, I see the static EVERY time the monitor wakes up. I'd been using this monitor with the same DVI cable on a 2007 Mac mini for over a year with no problems, so I don't think it's the monitor or the cable. I have to unplug and replug the DVI cable from the Mac Pro, then the static goes away and the monitor looks fine. Needless to say, that is getting annoying fast.Mac OS X (10.5.6)
Currently Being ModeratedMar 23, 2009 6:20 AM (in response to erise19)I'm also getting this same issue, if the display sleeps, and but the system is not in sleep. When I move the mouse to come out of sleep I get static. If I switch on the monitor on and off the image comes back. 2009 Mac Pro with 2x2.26 Quad-Core Xeon with the ATI Radeon HD 4870.
Sounds like there is a bug with this configuration.8-core Mac Pro with Radeon, Mac OS X (10.5.6)
Currently Being ModeratedMar 23, 2009 8:28 PM (in response to erise19)Enable the system preference for requiring a password to wake the computer from sleep or screen saver (System Preferences > Security). Next time you get the static from waking your display, enter your password and perhaps your display will return to normal. At least it does for me.Mac Pro, Mac OS X (10.5.6)
Currently Being ModeratedMar 23, 2009 11:15 PM (in response to chinhster)Is this the type of statics?
I had the issue once. I think it could be defective video cards because I had an old mac with an X1900 Xt with the same issue.Mac Pro 2.66Ghz 2009, Mac OS X (10.5.6), Radeon 4870
Currently Being ModeratedMar 24, 2009 6:00 PM (in response to chinhster)Yep - Me too - only happened once - GT120 with an LG L246WH 24" - I've since shifted to driving it via the VGA input rather than DVI/HDMI as that also fixed the resolution issue.MacBook Pro, Mac OS X (10.4.8)
Currently Being ModeratedMar 26, 2009 1:40 AM (in response to KenTaylor)This just happened to me today. I came back from a long day and woke up my new Mac Pro 2.26 GHz configured with 12GB Ram and an ATI Radeon HD 4870 graphics card. My Apple LED display turned on with a black screen and two thick bars of static going across the screen. I had to force shut down to restart and then it was normal. I've noticed this before, but with in some open windows, and in small portions. Is it safe to say that this happens only when the display is connected to the mini display port? Or when it wakes up from sleep mode? I can't imagine this is only happening to a few of us. I hope it can get fixed with a software update and it isn't hardware related.Mac Pro 2.26 GHz Quad-Core, 12GB RAM, 1TB HD, ATI Radeon HD 4870
Currently Being ModeratedMar 26, 2009 9:06 PM (in response to Thomas Hayes1)No. Imagine your TV turned on with no cable connected but instead of black and white noise, you get multicolored noise. The first time it happened, I rebooted the computer because I had no idea what had happened. The second (and last time) it happened, I figured the password dialog was up so once I entered my password, everything returned to normal.
It's been about a week and it hasn't occured since I posted about it.Mac Pro, Mac OS X (10.5.6)
Currently Being ModeratedMar 26, 2009 9:23 PM (in response to chinhster)Hi there.
I have gotten it a few times myself. Seems like most of you have the ATI card, but I have the nvidia stock, and I've seen it. Usually I can just turn the monitor (connected over dvi) off and on. My solution was to kill the power save and just turn it off manually.MacPro, Mac OS X (10.5.6), 2.26 Octo Core 12G Ram GT120
Currently Being ModeratedMar 27, 2009 7:09 AM (in response to chinhster)I have the same problem on my new MacPro. I have other machines that use this monitor fine. It only happens waking from black screen before the system has gone to sleep and it clears itself up on its own after about 30 seconds. Still, it is very annoying.PowerMac G5 and MacPro Dual 2.26 GHz and more, Mac OS X (10.5.6), HP LaserJet 4000TN
Currently Being ModeratedMar 31, 2009 12:54 PM (in response to Noah Robbin)I have this problem as well. I set one of the expose corners to "sleep display" and just move the mouse there to reset the monitor.

Currently Being ModeratedApr 2, 2009 6:33 PM (in response to Thomas Hayes1)No, that's not the kind of static that I'm getting. It looks like this for me:
I got a new ATI Radeon 4870 card from Apple, but it does the exact same thing. Everytime I wake the computer from sleep, it displays the static until I replug the DVI cable.Mac Pro, Mac OS X (10.5.6)
Currently Being ModeratedApr 4, 2009 4:48 PM (in response to chinhster)Me too! Got my Mac Pro Quad 2.93/Nvidia GT 120 about a week ago. The only thing I did that was not "vanilla" was that I used Migration Assistant to move my account from the Mac mini. Prior to that, used my Dell 2407 monitor with a Mac mini and never had this problem. I have the MP set to sleep but not require a password when waking. I don't remember this happening the first couple of days, but for the last few days it happens almost every time I wake the Mac. Pressing a key or moving the mouse doesn't help but a single mouse click has given me the desktop every time. This doesn't seem to be a monitor or video card issue since as reported here it is happening with both the ATI and Nvidia cards and with several brand/model of monitor. Mine is connected by DVI, but it looks like people have had problems with either DVI of displayport, is that right? Apple, is there a bug in this model?

Currently Being ModeratedApr 7, 2009 3:40 PM (in response to chinhster)I'm seeing this as well.. I'm running 2 monitors (30" Dell, 24" Dell) - 30" connected to DVI, 24" connected to mini-dvi.
Is anyone at Apple looking into this?mac pro, Mac OS X (10.5.6)
Currently Being ModeratedApr 7, 2009 6:20 PM (in response to chinhster)Add me to the list with this same issue on my new MacPro dual 2.26. I have 3 of the GT-120 video cards running 6 monitors, and I have seen this happen a couple of times when waking from sleep, but only affecting 1 or 2 of the monitors (both 24" Samsung). I get rid of the static either by turning the affected monitors off and back on, or by opening Dashboard and closing it.
I am guessing this is a problem somewhere in the system software that will hopefully go away with the 10.5.7 upgrade. Is anybody here involved in testing that beta release, who can determine whether that problem goes away with the upgrade?Nehalem 2x2.26 GHz, 8x2GB RAM, & 6 MONITORS!, Mac OS X (10.5.6)
