I went over to Magnolia in San Jose, yesterday, to look at the 50" 1080p Sammy. It actually was a very interesting test, as it turned out that the TV did not have a label on it to identify the model number. But as I went into the back where all the DLP's are located it only took one look around the room to know which one was the 1080p set. The contrast is so much better, the colors are so much deeper that you just know that this one has to be the 1080p set. The sales guy came by 5min. later and confirmed that indeed it was the new 5078.
The blacks are true blacks, and any other DLP next to it can only show shades of grey, where it should really show black.
Again, the color depth is amazing. The contrast just blows you away. I was hesitant about getting a 1080p set and was thinking about just getting the 720p. But now, I am in serious debates with my wife to see if we can spend the extra 1K that it will cost us to get the 1080p set.
I will wait for some of you brand new owners to answer the un-answered questions on page 1 first, before I pull the trigger. Looking forward to all of your posts. Make sure you find time for the forum and don't just watch TV all day long.
