I purchased an LG 29UM55 ultra wide monitor but can't get max resolution with my macbook air - only 1920 x 1080. My built in monitor is higher. I am connecting with a HDMI cable. Should I connect with a display port?
MacBook Air, OS X Yosemite (10.10)
Yes, DisplayPort should do it. HDMI - as far as a computer is concerned - is a TV connection, not a monitor.
Though it will still depend on the Air's video capability to support a 21:9 aspect ratio monitor with a resolution of 2560 x 1080.
Try holding the "Option/Alt" key when clicking on the "Scaled" button. This should give you a larger list of screen resolutions. Not sure if it will give you what you want, but it is something to try:

There are more screen resolution options now. What I do not know is whether it will give you an option for your specific display. I did this on my HDTV so its feedback via HDMI would not be the same as your LG 29UM55 ultra wide monitor.
Thanks Kurt. I just purchased and received an Accell UltraAV mini DisplayPort to DisplayPort cable and the resolution is just PERFECT.
Thanks Bob. I tried your suggestion and did get additional resolution options, however the monitor resolution didn't change.
I did resolve the issue by purchasing an Accell UltraAV mini DisplayPort to DisplayPort cable.
