Both of these videos are ads for LG products. I don’t think they can accurately reproduce the depth perception to fool a person into thinking they are actually looking through a window, but it does make for funny videos. Every time I watch that first one, I get a good laugh even though I know they are actors.
So, to answer my own question, I’d go buy me a TV if the picture quality were truly that realistic. Until that happens, I’ll save a few dollars and keep watching what I currently have at home.
