I just found using the full regular Dex mode it will only display 1920x1080. If I change it to DeX Mirroring mode the resolution changes to 3840x2160. Yes, this not what I expected when buying the DeX Pad and a 4k monitor, but switching is easy if you are just looking to watch a movie on Netflix in 4k and then use office/computer type apps in DeX mode at 1080 or less. Not making any excuses for Samsung but it's a workaround that's suffice for me until the monitor can just stay 4k in DeX mode. Hope this helps some. The HDR 10 Dolby Atmos Aquaman trailer on Youtube was unbelievable on my 4k monitor and wearing headphones. Happy holidays all, Samsung is still the leader in my book.
