Q: Does it come with the parts to connect it to a wall mount?

A: Yes there is a plate included for that, I did not use it though, so don't know if it matches anything particular

Q: Has anyone mounted this monitor via VESA mount? I see in the description and specs that it is mountable, but when viewing the rear images provided it does not look like there are any bolt holes for a VESA mount. Any insight would be appreciated.

A: It comes with a wall plate to attach it to any wall mount that is VESA 100 x 100 compatible. You unscrew the stand, and mount the plate using the same 2 screws. Then you can attach the plate to whatever wall mount you are going to use.

Q: Will I be able to split the screen? And if yes, how would it be done? Looking to use this in a home office.

A: Yes. You can split screen. Now your question doesn't clarify if you want to: A) split screen with one computer or B) connect 2 computers to the monitor. Both are possible with this monitor. A) You can use multiple apps at the same time using the Windows 10 or Mac OS split screen feature. B) You can use the Picture By Picture feature of the monitor, where you plug 2 different sources to it. It would split the screen and show both sources. Keep in mind each sources would use its own keyboard and mouse.

Q: How long is the supplied Thunderbolt cable?

A: I did not measure it but it is long enough to be attached to the monitor and snaked through the built-in cord management neck and out with about two feet+ leftover.

Q: Can it be connected to MacBook Pro by thunderbolt to thunderbolt without usb c to display port adapter?

A: Yes! It is ready to go right out of the box and includes a USB C cable! I can’t stress enough how amazing this monitor is! I use it with my 2016 MacBook Pro and it’s perfection.

Q: What size is this mountable??

A: This is a beautiful monitor. It comes with a metal bracket for wall mounting. I did not use this feature, but according to Samsung website, Wall-Mount (Size mm) 100 x 100. Hope this helps.

Q: Can I use this with 2 desktop computers? 1 split screen for 2 computers

A: Yes. You'd just need to turn on PIP/PBP mode then select the two different sources for each of the split screens

Q: Does the height adjust up and down and if so to what extent?

A: . Height adjustability: 3.94-inches (100mm) . Display Tilt: -14-22 degrees
