one thing I noticed recently, 4k monitors which do not contain any "smart" features often cost much more than a much larger 4k tv. I suspect all the built in crap that the TVs ship with at least partially account for this price difference.
I run a company that develops Smart TV and OTT apps. When we started around 2010 it was cheaper to buy a Samsung Blu-Ray with the Smart TV platform and an HD/HDMI monitor then to buy a Samsung Smart TV.
