I'm not really an expert, but I found a lot of TVs are set up in a way it's best to view them far away. 4 years ago, I tried to use a 46 inch Sony W3500 as a computer monitor. The picture was nice and clear, yes, but my eyes were quickly becoming tired after being exposed to such large screen nearby. Even with brightness down, the luminance was too much for me to really treat it as a monitor, the screen door effect kept me from getting closer. It definitely was doable, just a lot inconvenient.
