    So, my wife was helping me place a cover atop a shelf so we could paint. Like a dummy, I overlooked the fact my 15" MBP (2017) was atop said shelf with the LG supplied cable fed into my 5K display atop my desk.

    Before you know it, my lovely (relatively new) 15" MBP was lying top down upon the concrete floor after falling about 5' and now with the LG supplied TB3 cord ripped out of it. The cord was toast. I was pissed.

    Next day I called LG and asked if they'd take sympathy upon me and send me a new cable. LG graciously agreed and sent one out free of charge. Thanks LG!

    While waiting, I became impatient and ordered a TB3 cable from Amazon b/c I love my monitor & had no clue when the LG cable would arrive. (fortunately, aside a small bruise or two, MBP was fine - lucky)

    Cable arrives>Plug it in>Review System Preferences>Monitor

    Suddenly, with this new cable, I can rotate my monitor!!!!!!! This = happy me!! A near tragic event helped me to serendipitously stumble upon this sadly missing feature using the LG supplied TB3 cable.

    P.S. Once the LG replacement arrived, tried it, of course. No ability to rotate the screen.

    You're welcome.

    *I've edited the initial post b/c I accidentally attached a photo of the wrong cable - it's now been corrected.

    That is wild. I tried a mono price Thunderbolt 3 cable I purchased over a year ago and the same result. Rotation is now available. Weird that it works with standard TB3 certified cables but not the one provided by the vendor.

    Thank you for sharing, bcaslis. I agree, it strikes nonsensical the LG cable does'nt support the function while 3rd party offerings do. Ah, well..it's what it is. Despite this fact, I am a total fan of the monitor despite many haters and, I've had it for a good while.

    I think you're saying you acquired a low budget cord (as compared to the $60 cord I bought) and it worked; yes?

    Clearly, I wouldn't know the answer b/c I spent the bucks as detailed in the screen shot..perhaps unnecessarily!!

    Great find!

    My Ultrafine 5K intermittently blacks out for a few seconds. (happens a few times a week)
    Does this cable solve that too?

    Makes me wonder what else a third-party cable helps/enables with the LG monitor.

    Nice, thanks for sharing! I, too, would like to know if it enables any other features, performance, or is generally better for the monitor.

    Ironic as I have the 4K and was curious if I could find a cable that was a little more pliable than the one it came with.

    Wouldn't have surprised me if on some level it was proprietary but it looks like it isn't.

    Now to search for one that is a little less Han in Carbonite.
