I have read a lot on here about mattes. I have also seen many brag about the difference it makes matting off the black or greay area on a 4:3 set. I decided to try this. My conclusion: It does make a difference. Big enough of a difference to have everyone look at you like you have lost your marbles? IMHO no. I do have black already on the background of my Toshiba 36" TV. The mattes were darker, but not worth all of the fuss. Just my opinion.
