I don't care what anyone says, Vizios are very good TVs.
They have a good number of documented failures after only a few years. Could be model or make, not sure. Price to picture ratio isn't good enough for me to take the risk to see if I get lucky. Vizio is not doing anything magical to offer the picture, performance and reliability that Sony and others can do for less. It doesn't take much for a TV to stop working. Just cutting costs on the amount of solder used is enough and quite common.
Just walk into your local Best Buy, Walmart, or whatever and see whichever one LOOKS the best. About the only thing that I look for is whether the blacks look black, and if colors are vivid (not glowing, but not washed out either).
That's about the worst advice you can give. They are usually never ever calibrated and give you little idea of what they can or should look like. Plus you don't know how the routing and splitting is being handled and they run different sources often.
The Sharp Quattron is an interesting Idea but every time I see one, it looks unnaturally yellow, like all the people on screen have jaundice or something.
Same answer, poor or no calibration. You can adjust the yellow levels down to nothing if you like.
