I have been considering buying a big-screen LCD TV but all the ones I see in showrooms have artifacts during action scenes. Are there any models that eliminate artifacts or is that just something you have to learn to live with. I understand that smaller screens are going to look clearer than bigger ones, but I don't like the idea of having something so noticeable added to the picture. I end up staring angrily at the artifacts instead of whats going on on-screen. Any suggestions from the electronics geeks among you? Thanks in advance for any help you might be able to provide.
