OS X Mavericks Multiple Displays demoed on six 27-inch displays (with video)

“Now that developers have their paws on the developer preview of Apple’s OS X Mavericks, we’re starting to see demonstrations of the new operating system’s capabilities appear outside of the safety of Apple’s keynote address,” Meghan McDonough reports for Digital Trends.

“Via YouTube, one user with a sweet-looking six (!) 27-inch monitor setup goes through the pros and cons of Apple’s new full-screen app support within a multi-monitor configuration,” McDonough reports. “MrThaiBox123, the YouTube user who uploaded the video of Mavericks multi-monitor in action, demonstrates how a full-screen app in Mountain Lion would blank out all of the other displays except the one where the app was at full-screen.”

McDonough reports, ” In Mavericks, this doesn’t happen.”

    1. I have two usage cases:

      Log file examination (especially Apache)

      Quick and dirty trimming of AV files in QuickTime Player – much greater finite control over placement of the play head when the window is absurdly wide.

      Beyond those two? Not so sure!

    2. Large contiguous spreadsheets in Numbers. Working with a single sheet (within which are tables) all visible at the same time, makes audit and analysis very quick. I stretch the spreadsheet across two monitors.

  1. Useful video thanks, seems that this way of working is better for multitasking with different apps, ultimately you can have one background spread across multiple monitors you just can’t change all at once, something that surely is just for aesthetic purposes!

    1. Yeah really, worrying about whether one large multi-screen wallpaper correctly matches consistently? Sounds like something Fandroid would worry over. I use two monitors and all this is a non-issue for me. I never stretch apps over two monitors as I don’t like the break line created by the right and left edge of the monitor frames. This guy points out the need for a 47″ or larger Retina Display monitor. I still can’t figure out why 30″ has almost disappeared. Waaay better then 27″.

  2. I think the restrictions brought up may be “stretching it” a bit. Not sure why with six monitors you’d need to stretch across two.

    I guess one thing lacking here is an example of your work flow that would be negatively impacted by the new changes.

  3. Give me a break. I guess I can see that you might want to have a window spread across more than one monitor, but honestly I can’t see wanting to do that much. It is a bit of a pain really. And the bit about wanting to have your desktop image spread across multiple screens? Get a life. If you have some functional reason why the new way of handling multiple monitors doesn’t work then ok, but just not liking how it handles the desktop picture seems a bit lame to me.

  4. So biggest problem is that you cannot have one large wallpaper across 6 display’s and applications don’t stretch across screens, oh well, that’s going to cause serious delays to the final build.

    Oh, sorry, I totally forgot that this is a developer preview, i.e., unfinished work. Lets not write it off too early!!

    1. Demoed.

      You notice part of the video where he opens the command center. You can drag and move applications anywhere and switch apps around desktops.

      Demoed in the keynote, too.

  5. This new way seems to work well. Fixing the full screen app issue which disabled other monitors is great. However many people still say they liked how multiple displays in SL worked the best. How did it work exactly?? I never used it cause I never need to.

  6. Hmm… after watching video it would seem the implementation in Mavericks is far more scalable and better. Sure, you can’t have one stupid desktop image span your 6 monitors but I use my desktop images to quickly tell which space I’m in so no loss here.

  7. We seem to be all caught up with giant wallpapers and forgot about most of the new features, such as having menu bars on all displays, the ability to have a dock on any display, the ability to have multiple apps open full screen, integration with airplay, etc. I switch desktop views so seldom, the wallpaper issue won’t be a problem. I’m guessing the reason for removing the ability to have a window across multiple displays is because it doesn’t work very well if your displays aren’t all the same resolution, or if you remote connect to your Mac (as I do). Personally, I welcome the changes. I want menu bar and dock on all displays. It sucks having an app open on the far left, but having to move your mouse half way across the world to get to it’s menu. I also really want the multi full screen capability, as it will be great for tutorials and training videos. Video full screen one one, actual work on the other.

  8. The spanning is actually a REALLY annoying problem… I use 3 displays, and consistently have Excel spread over 2 windows at once, under the default Maverick settings, that is no longer possible… REALLY ANNOYING.

    I WANT to have the multiple menu bars and docks and multiple full screens, but if it means I cannot spread Photoshop over 2 screens (the main viewer) or Excel, then I am afraid I will need to revert to 10.8’s solution… Please Apply change this before launch!

  9. Please do not question other why they need multiple monitors with that tone!
    FYI, some of us really needs to stretch application. If you trade currency, you have to be able to stretch the trading platform!
    So this update is really bad for me, and I have to revert to previous version.

  10. I agree with the video. Mavericks has made mess of the multiple screen purpose. They didn’t get it right in Mountain Lion and made it worst in Mavericks. That’s probably why most people use PC’s for this kind of stuff. For example, video gaming (racing, adventure, war games like Call of Duty to have side visions, etc.) across multiple monitors that curves around the gamer (with 3 monitors). Large curved screens are still pretty expensive and therefore, not too popular yet. Another example, musicians working on mixer software that expands across multiple monitors enabling them to see more of the recorded tracks. Third example, graphic designers, animators, movie/video editors could make good use of the extra screen real estate to their benefit (similar to a musician to expand the tracks instead of having to scroll back and forth). In this case, audio and video tracks. So there you have it, to those that are numb to these kinds of applications and cannot acknowledge the purpose of expanding across two or more monitors. A big monitor can only show as much as it’s resolution allows…so instead of one 32″ hdtv/monitor, why not 3 if you’re true to your craft or work efficiently. It’s not at all impractical as some might think. So be open minded, the video did make a good comparison between Mavericks and Mt Lion in regards to multi monitor features “designed” by Apple. In my opinion, Apple needs to work more on that.
