...except the height adjustable option is a whopping US$400 extra, and the VESA option is BTO only, can't be added later and comes
without any stand, yet is no cheaper than the model including the basic stand. Even the LG Ultrafine does better than that. We don't know if this new Samsung will have those features but most "prosumer" level displays do. Sorry, the issue isn't dead. The limited stand has always been (and still is) a flaw of Apple displays and the iMac.
(To be fair, the 4k+ Mateviews I'm using can't be VESA mounted - but they get some slack for being dirt cheap for what they are, and they
do have height adjustment).
Example: At $1299 the LG isn't sufficiently cheaper to make me settle for its obvious lesser aspects (materials, brightness, sound, etc.).
The LG is also, AFAIK, using old tech that treats it as two DisplayPort 1.2 displays welded together - which could be an issue in the future. OTOH, the Studio Display
with a height-adjustable stand costs $2000 whereas that's included with the LG.
I've decided to go for a much cheaper 3rd-party solution but if I'd decided to spring for 5k I'd be a bit stuck on the swings and roundabouts over LG vs Studio Display. The Samsung sounds like a welcome addition - although all of the 'smart TV' stuff seems like "something else to go wrong".
Personally, I think that any speakers built into a display are going to be inferior to a half-decent set of external speakers - much the same for microphones or webcams - and are
totally irrelevant if you're looking for a second display. All of these displays seem to be more suited as laptop docking stations than as part of a desktop system.
