Yes Ira, better than imac 27" if only for fact that it turns left right. Love that as in room I watch tV with too in different part room than sit . With Apple I would do that, but less elegant, as had to physically turn whole thing, no swivel.
For color & sharpness, fine.. maybe bit less as 4k, but negligible.
Better than LG for aforementioned swivels, and also has buttons in front, LG more cumbersome buttons.
Brightness F!/ F2 keys not working so sent email in about that.
