I have this same monitor (LG 38WK95C-W) along with my new Mac Mini (I finally retired my 2012 27” iMac along with a 2nd Dell 24” monitor next to it). So much cleaner on my desk now just having this 1 huge monitor - and I don’t miss having a 2nd monitor at all (I don’t need it). The monitor stand is perfect as well…does not take up much room at all and I can place all of my other things easily on my relatively small desk.
One thing that is bad though about this monitor - do not plug in any hard drives into the back of the monitor’s USB ports (I use the USB-C connection)! I had my Time Machine external drive plugged in and it would always disconnect itself every time I woke my Mac Mini from sleep (for whatever reason it would forcibly lose the connection to the drive and then re-connect, giving me that horrible disk ejected improperly message). I think this is why my Time Machine drive kept getting corrupted and I couldn’t figure out why - now I know. Took me weeks to figure out. So now all I keep plugged in is my Logitech unifying receiver for my mouse and keyboard, along with my Logitech Brio webcam (both work very well being plugged into the monitor itself, with full resolution to the webcam). I wish LG would fix the external hard drives issue with this monitor - it’s so weird that it forces a disconnection for a short period of time when waking from sleep.
