Any big 34 inch or 43 inch 5K monitors coming anytime soon ? if no, then I will just go ahead and buy the LG 5K 27 inch one. Im getting the new Macbook pro 2017 next week, so need a monitor to work on.
A 43" monitor!? I'd need a neck brace after a day with that! Not sure why you'd need thunderbolt ports on a monitor but a TV is your best bet if you somehow need a window sized display in your face. Not really much movement in a 5K display as it's an odd standard that only really applies to Apple, so there could be something but it'd be latest tech. So if there's nothing now you'll be waiting until CES next year when anything would come about.
