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)
I'd like to thank you a lot.
I've been looking around the internet to solve my problem, and your solution has fit perfectly!
My monitor is LG 25UM58. (25" ultrawide)
Really helpful!
@genriquediaz: This worked for me. Thank you for the screenshots! I tried SwitchResX before but it didn't work, but I tried it with your exact settings and it worked. You rock!
I have a 32" LG Ultrawide and MacBook Pro (early 2013).
I my case it was the cable!
I have MacBook Pro (Retina, Mid 2012) and just bought the LG 34UM57. I connected my previous monitor with Mini DisplayPort to HDMI and has no problem. I use the same cable with the new LG monitor, but it kept saying the current resolution is 1920 x 1080 60Hz. The recommend resolution is 2560 x 1080 60Hz.
After hours of research and reading all the reply to this post, I bought a new cable (link below) that supports 4K resolution up to UHD 3840 x 2160 @ 30Hz. I finally found out that my old cable was for 1920 x 1080 resolution, which is why it kept flashing me that window...the current resolution. This new cable support more than the recommend resolution and is only $15!

I've got the solution for everyone!!!
The LG should come with Displayport not Mini-Displayport on the back. You'll need to get the Displayport to displayport cable and get the Displayport to Mini-displayport adapter and Voila! 2565x1080 shows up! No need for software or anything else! Hope this helps EVERYONE!
I used this with my LG Ultrawide 29UM68 on my MacBook Air!
I bought an LG29UM58 for my MacBookPro. Fuzzier than desired fonts on screen with an HDMI to HDMI cable.
Tried the SWITCH RES X App to insert a custom 2560x1080 resolution, but had too many concerns about getting thru Apple's security measures to install RES X correctly.
Then bought an HDMI to display port adapter (4K) with a male-to-male HDMI cable (also 4K). I still see no way to increase to the desired 2560x1080 resolution using the Display System Preferences option which have a maximum 1920x1200 setting. Arrgghh!
How to display 2560x1080 on external monitor from MBP or MBA?
