Is the H5600 series good enough to use as a second monitor?
Hello and welcome, Canyonero! :smileyhappy:
You can definitely use the UE22H5600AKXXU as a monitor (as well as a Smart TV of course). You'll have to bear in mind that it doesn't have VGA connections. We also have a wide range of monitors that do though, which you can find here: http://www.samsung.com/uk/consumer/it/monitor/.
A top tip if you do use the TV as a monitor through a HDMI connection is to rename the HDMI input to PC, as this will allow for a greater range of refresh rates and stop any overscan.
Hopefully, though, someone in the Community who's using a H5600 as a monitor can let you know how they're finding it.
