Just wanted to mention that the brand new Samsung S9 (5K, 27", matte, fully adjustable, TB4) has already been discounted to $1350 $1300. That’s not quite as cheap as the LG, but it’s the better monitor overall. And it’s still easily $900+ cheaper than a reasonably spec’ed Apple SD leaving that thing as the over-priced and over-engineered obscenity it has always been.

This is right now certainly what I’d buy if I were in the 5K/27" market.
(I will admit though the “Smart TV Apps” and “Gaming Hub” malarkey has me worried, but I trust that should be capable of being thoroughly disabled.)
Edit: Samsung just put the display on sale. Amazon now has the S9 at $1300, its lowest price ever (previously only once during Prime day).
