Since you cannot see the pixels, these stair-stepping artifacts are not likely to be caused by your screen's resolution.
Far more likely is that you are seeing compression artifacts, or color irregularities, or any number of issues which may be due either to the source, or to the processing of your monitor. But the resolution of your monitor is absolutely sufficient at whatever your viewing distance is, since, as you state, you do not see the pixels.
Honestly, some of these arguments are akin to someone being convinced that they can see differences between two equally polished surfaces, because a marketer told them that one is made of a material which has smaller molecules than the material of the other.
CNET's Geoffrey Morrison noted in the article I linked earlier that doubling the resolution is a cheap and easy way for manufacturers to up-sell Joe Public, because bigger numbers are easy to tout.
BarMan01 is a perfect example of why this works: his new 4k set will likely have better software, better motion blur control, better color rendition, etc. than his old 1080 set. When e gets it home, he will be happy attributing all of these improvements to the higher resolution of the glass, even though in reality the effective resolution from where he normally sits has not changed a bit.
Don't get me wrong, I am all for larger screens and there is a point where 4k makes sense in a regular home theater. But that point is not valid for 60" screens viewed from 12 feet or so.
