I'm sure this question have been answered before on the board. However, using the search engine, I can't find an answer anywhere: What is screen tearing? What does it look like? Like I said, I'm sure it's been answered before, but I can't find it anywhere. I'm thinking of buying the Samsung LE-26R51B, and I'd REALLY like to know what flaws I need to look for, before buying it. Thanks.
