Q: How to display 2560x1080 on external monitor from MBP or MBA?

Is there any way to make MBP 17 (Intel HD and nVidia GT graphics, SnowLeo) or MBA 13 (Mountain Lion) display 2560x1080 on external monitor (LG 29" ultrawide)? My MacPro with RadeonX1900 card (10.5.8) does it perfectly but I cannot find a way to get the laptops to do it. Tried res. switching apps, still no good. Thanks.

MacBook Pro, Mac OS X (10.6.8)

    Dear Keap

    Thanks Keap. Excellent i had tried miniport display to DVI cable, minoport dispaly to HDMI cable and on reading apple community support tried miniport display to display and the resolution at 2560x1080 worked and resolution is fine. I carried this out on my 11" MacBook Air to external monitor LG25UM65 and compatibility was good.

    The cable was from startech.com

    Thanks

    On the LG Ultrawide 29EA93 model the MacMini displays beautifully yin 2560x1080 with the mini-displayport to displayport cable.

     

    But when I switch the monitor into PBP mode (2 inputs each with half of the screen - done in hardware on the monitor) I can't get the Mac to throw the screen in 1280x1080 ... which leaves everything rather squished.  Any ideas how I can get a working resolution for that?

    The star tech cable can be purchased from Amazon.

    Great suggestion. I've just connect my AOC Q2963pm 2560x1080 29" monitor (http://us.aoc.com/monitor_displays/q2963pm) to my MacBook Pro (Retina, 13-inch, Late 2013) through a regular HDMI cable.

     

    I do get an image, but the font is not 100% clear, which I think in the long run will ruin my eyes. I've also installed the SwitchResX software and configured Screen Shot 2014-07-20 at 12.15.10.png

     

    What else can I do to make this work sharper? Would changing cable work? To which cable?

     

    Thnx for the advice!

    Try using display port to display port cable. Cinch is good to see more than one application on the screen.

     

    Kind regards

    I bought a Display port to Mini Display cable, but when connecting, I don't get any image on AOC screen... Reverted back to HDMI and that works, but with the blur.
    Do I need to have SwitchResX running when using the DP cable? What setting on the AOC should I use: It's the "DP" one right, not the D-SUB. Just checking.

     

    Any other ideas?

     

    Thnx

    For those using the MBP (Retina, Late 2013), I solved the problem connecting via HDMI to HDMI cable. The SwitchResX (4.4.1) will automatically recognise the default resolution of the monitor. If not you can add it using the Custom Resolutions tab. It worked for me using the 60Hz Scan rate

     

    Hope it helps!

    Bought my new monitor today and ran in to this problem.  Boooo!


    Read this discussion and solved it with SwitchResX. Yaay! 


    My set up:

    MBA 2012

    LG 25UM65-P monitor

    Belkin MDP to HDMI cable


    BTW, SwitchResX not the friendliest program I ever used, but I got there.


    Thanks to everyone who took the trouble to post.

    A further note to my post above, one month later.

     

    MBA got stolen on a train.  Bought a MBP 13" to replace it.  This time SwitchResX did not solve the connection to the LG 25UM65, despite 3 hours of trying during which I learned more about monitors than I ever wanted to know.

     

    I then plugged in the HDMI to HDMI cable which came with the monitor (MBP has an HDMI socket which the MBA did not) and voila, the correct resolution was on the standard list in SwitchResX.  Selected it, everything worked.

    I just hooked my LG 25UM65 (21:9 2560x1080) to MacBook Air 11" (2013 model, Intel HD Graphics 5000) via mini display port -> HDMI cable.

    Loaded SwitchResX (latest version, at the moment of writing this post: SwitchResX 4.4.1).

     

    I can confirm that 2560x1080 is working via HDMI.

    hi BolléSG, good to see you get it working with the same macbook air as mine, did not get the "not installed" status with the custom resolution? can you please share the detailed configuration (screenshot?) so that I can try to mirror the same? thanks very much!

    This keeps happening to me when I try and do 2560x1080 over mini display port - display port.  I have the 34 inch LG w/ mba11 yosemite.  HDMI w/switchresx doesn't do anything but output a 1080p signal.

    Brilliant, I used a star tech mini displayport to displayport cable and it worked instantly. I'd tried a couple of active dvi, including Apple's) and although it showed the correct resolution, the fonts were unreadable.

    Exactly the same problem with my LG 25UM65 connected to my MBP mid-2012 (Intel HD 4000) via mini displayport to Displayport. I tried SwitchRes without success...

    The best resolution which works is 2048x864...

     

    Have you found a solution ? Someone to help me ?

     

    Thx
