When I received the unit back, it was working fine again. They left it on for 2 days and couldn't fault the same problem I reported. I had to send it back to the nearest Samsung Repair Centre. I did have an issue the first week after using the display - The built-in speaker stopped working one morning when I was about to start a meeting with my work colleagues.

When you have a monitor that has this many ports, you really should make the best use of them. You may or may not like the PIP/PBP feature as it reduces the viewable screen if have must see the desktop of both devices them simultaneously. No hassle from pluging and unplugging HDMI or TB3 cables. Samsung 3 year(s) limited warranty against manufacturer defects.

The only UBS-C port on my Surface device is already the video input port and draws power from the Samsung monitor! This should be a relief to Surface device owners considering a bigger display for viewing comfort. Initially I thought Microsoft didn't support Thunderbolt but they actually do (and no you don't need to spend another $200 to get this Surface Dock).

It works with my Windows Surface Pro 7 and allows me to not use the original 65W charger. All made possible by this 85W Thunderbolt 3 port in the back (the other TB3 port is only 15W which is not really powerful enough to charge your laptop). Love the minimalism of using only one cable for power and video input. I couldn't order it from other online retailers but Samsung so I had to pay the RRP.
