I used to use a monitor with 5 separate buttons round the back,and the single JOG button controlling everything is a pure joy to use. Admittedly it took me a short time to get my head around how to best use it, but it is a good idea for a monitor that does not have buttons on the front. BUT I sem to have great trouble getting my computers (2 desktop PCs and various Raspberry Pi SBCs all connected via a switch box) to always work with it. Sometimes the only way to get one of the PCs to display anything is to turn off the monitor by disconnecting the power, then turning it back on again. Also there are some combinations of graphics card and GRUB2 resolutions that simply do not display anything but used to work on the Viewsonic VX3211-2k-MHD that was replaced. All these problems occur using the same 2560x1440 resolution that I used to use with no problems. There are two HDMI inputs and one DP input, BUT one the HDMI1 input will not handle 4k @60Hz as it will only go to 30Hz at this resolution. The picture in picture option is fun and sometimes very useful when I need to monitor my RPi based Minecraft server while using a desktop PC. When in use the 4k@60Hz picture is awesome for gaming. :-) So overall it had the potential to be a great monitor, but it falls short by being too quirky for me to recommend it to anyone. (Sorry Samsung as I normally really like your products.)

JOG button is used for power on/off and input selection. Had they used 2 dumb switches for this it would have been an excellent monitor. The JOB button has been made "intelligent" and seems to have a mind of its own. When I power up the monitor I expect it to receive the input from my PC. Instead it comes up blank and I have literally spent 20 minutes on each of 2 days getting it to accept a signal. Selecting the correct source is not enough. It seems I have to power cycle my PC after the monitor is on for it to detect the signal.
