All tv`s , that is ALL tv`s sold anywhere , can have a good picture or bad picture.
What you need to look for is a tv that fits your needs and your spec`s.
For me it was the F8000 , but the main board failed after 6 moths.
Good or bad ?
Good , as it turns out the main board was throwing my color settings all over the place and once the board failed and was replaced , the tv has a better more stable picture.
That being said , the last Sony I tried was the XBR929 and that was a few years ago.
Doing further study , I have concluded that Sony is no longer the best.
Is Samsung ? , they get close then fall behind , but they recover.
Stay away from cheap tv`s , if I owned a Vizio tv and the main board failed under warranty Vizio would have replaced the set not fixed it.
So are disposable tv good or bad ?
I am a long time Mac user , and was saddened to find out that the 2014 Mac Mini has soldered ram , and no dedicated GPU.
Anyway , I guess I trying to say if any tv you like has the right apps and connectivity then try it.
