    I have two Apple brand displays and two Apple installed NVIDIA GeForce GT 120 cards. Hot-swap your video cables: this always fixes things until you reboot. If you're lucky, both displays will work once or twice after (complete shutdown and reboot cycles), then you you have to hot-swap again. I did officially report this to Apple Bug Reporting, they gathered more info from me but that is about it. I even tried running both displays off of one video card with a mini-display to dvi adapter as well, no luck, same results.

     

    The suggestion of buying new hardware to address this brand new SOFTWARE BUG is obviously from a whiney fan-boy, not a thinker.

    Yeah, those pesky fan-boys are always annoying, better to tinker and hack to try and get things to work with sub-par performance.

    Well, I'm glad I found this thread, but it's not helped much on this end.

     

    I've got a 2009 Mac Pro with three GT120 cards in it, each driving a different monitor (I know... more cards than I need, but it made the cabling easier... long story). After playing around with the tips in this thread, I can get one monitor to consistently work rotated, even across reboots, but seems only if it's the monitor connected to the card in slot 0. Any rotated monitor connected to any other card gets the black screen where only the cursor shows up. I've tried the hot-swapping, tried the updated nvidia drivers, same problem.

     

    I'm on 10.8.2 now... What version of MacOS would I need to roll back to in order to fix this? And is there a procedure for doing this someplace? I've got a Snow Leopard disk around here somehwere...

     

    This whole fiasco has been pretty irritating and I really hope somebody at Apple is paying attention. I've probably got three or four hours into monitor cable gymnastics at this point trying to figure a solution.

    I'm at 10.7.4 with no issues. 10.7.5 introduces the problem on Lion...

    Thanks Milo... That makes sense... I updated to 10.7.5 and that's when this problem bit me. I did the 10.8 upgrade specifically so I could install the new NVidia drivers, but that was a dead end.

     

    Any suggestions for getting from 10.8.2 back to 10.7.4?

     

    At this point, I'm half considering just ordering one of the ATI cards and hoping that fixes the problem...

  • tmikaeld Level 1 Level 1 (0 points)

    Can't "backgrade" OS X unfortunately.

     

    I run 3 screens on an GTX 670 with latest Nvidia drivers, works like a charm.

     

    I'd recommend that over ATI if you want optimal performance, and since the iMAC's run the 6XX series it will be supported in the future.

  • milo jah Level 1 Level 1 (10 points)

    The problem occurred immediately for me when I upgraded to 10.7(.5) from Snow Leopard, so I had made a full clone of my boot disk before the upgrade.

     

    So, I ended up rolling back to 10.6, and reupgrading to 10.7, disabling auto updates, and manually installing the 10.7.4 combo.

     

    You might be able to reinstall 10.7 and use a Time Machine from 10.8, but I don't know for sure.

     

    Good luck.

  • jscheller Level 1 Level 1 (0 points)

    Thanks Milo... Sounds like I may be a little screwed there. I should have made a full backup before I did the OS upgrade. Getting too casual.

     

    Tmikaeld, thanks for the advice. I'll research the 670. I've got a weird situation because I've got three 5 meter long mini-DP cables pulled through a floor conduit from the machine to the monitors... The three GT 120's made connecting them easy, but if I go with a single card I'm doing DVI-to-DP gymnastics somewhere (no way to pull a DVI cable through that pipe.) The ATI 5570 was attractive from the standpoint of having two mini DP connections and I'd only have to screw around with one to get the third monitor working, or maybe leaving one of the GT120s active if I could get that frankenstein mix working.

     

    As it stands, still pretty ticked this whole issue came up...

  • jscheller Level 1 Level 1 (0 points)

    Does anybody know if you can put multiple GTX670s or ATI 5570's into a 2009 Mac Pro?

  • tmikaeld Level 1 Level 1 (0 points)

    jscheller: You are in luck, DP is compatible with DVI adapters are they are cheap. Even mini-DP to DP adapter is cheap (have one myself). Check online and local stores and i'm sure you will find them.

  • jscheller Level 1 Level 1 (0 points)

    That may be the easiest route to go then... Thanks.

  • tmikaeld Level 1 Level 1 (0 points)

    Hm, for some reason i cannot find DP to DVI adapter online at all. Maybe i mixed it up with HDMI to DVI . And unfortunately 670 only have 1 DP output.

    Apparently, Apple is tracking the issue with BUG ID: 11344582.

     

    They don't seem to track participation here, so everyone who has this issue should open a bug report at https://bugreport.apple.com . It probably won't hurt to reference bug id 11344582 in the text. The more associated bug reports, the higher the priority to get a fix.

    Hi All,

      Mirror: Off

      Online: Yes

      Rotation: 90

      Television: Yes

     

     

    --------------------------------------------

     

    Whenever I restart, the displays do not restore to their previons settings and rotated displays are either blanked out or they appear with no rotation applied. The blanked out displays show a mouse cursor but no video.

     

     

    I can't see how this can be a Graphics driver problem, this configuration had worked fine prior to Mac OS X 10.7 (I'm now on the latest version of 10.8.

     

    Anyway, just wanted to clarify the video cards that I have and see if anyone has the same hardware and if they have found a way of getting around the problem?

     

    Cheers

    Dave
