Do any of the usb to displayport adapters support a 21:9 ultrawide output?
Hi Shane,
Thanks for posting. I’d be happy to answer your question. Our USB 4K adapter (http://plugable.com/products/uga-4kdp) should work fine on a 21:9 monitor assuming a 3440x1440 resolution and a 30Hz refresh. There are actually two reviews on our Amazon listing for this product (http://www.amazon.com/Plugable-Displa…where) customers have reported success with this LG monitor:

Let us know if you have any additional questions.
Thank you,
