    Hey everyone,

    I just got a new LG 55UF77 Ultra HDTV.

    I connected my early 2015 13" Macbook pro with an HDMI cable, but when I connect it and go to
    "About This Mac" - "Displays" it shows "LG TV Display 30.5-inch (1920x1080)"

    How can I get it to find the correct tv? I've never even connected my macbook to a 30.5" tv before.

    The picture looks blurry regardless of if I choose 1080p or 4K mode.

    Any ideas?

    I recommend you update the software on the TV, the Hardware Identifier that functions through HDMI is clearly not identifying itself or its capabilities correctly(reso)..

    Also I recommend looking over this article as well.. https://support.apple.com/en-us/HT202856

    Our monitor is a 27UD88, but same issue. Found the following things helped:
    • In the monitor menu, go to Picture > Picture Adjust, and turn HDMI Ultra HD Deep Color on.
    • In the Display section of System Preferences, hold down the Option key while clicking on the Scaled button; then you will see more options for resolution.
    For some reason, my Macbook (mid-2014 15") still sees the monitor as a 30.5" 1920x1080 display, but I'm still working on that.
