I am interested in buying a 4K Apple TV, but I have limited space in my living room. I need a TV for it that isn't too much larger than a 27-inch iMac that I have sitting on my coffee table. Maybe a 36-inch model? Anyway, I looked on Amazon but had trouble finding small 4K TVs. Can anybody recommend a good model that would work on a coffee table? Thanks if you have any info.
