Well, all this fussin by midnight77 about artifacts got me wonderin as to just exactly what it was he was seeing. So last night I decided to do some serious experimentation of my own to see if I could in any way duplicate what has had him in fits the past week or so.
First, let me explain my viewing conditions and position as it relates to the TV (60EX500). My "Cave" is in a 24 x 24 detached garage that has been converted to a theater room. I normally sit in a recliner about 12 feet from the TV. Recently, I added more seating by way of floor seating that sits about 6 feet from the TV. Yeah, it's a little close but when you're watching concert blurays, it immerses you just like you're at the show leaning on the stage. I have directv hd and am running an OPPO 83SE blu-ray.
OK, on to the "meat and taters". Last night while watching the NLCS and thoroughly enjoying the picture from 12 feet, I decided to sit in the "front row" and take a peek. Boy, what a difference. Graphics such as the little pitch count box displayed all kinds of what appeared to be picture distortion all around the edges. It did seem to help when I turned the sharpness from 5 down to min but it never completely went away. Moving back and forth between 6 and 12 feet helped but even at 12 feet I could still barely see these "artifacts" with a heavy emphasis on the word "barely". So there ARE some artifacts to be seen but I couldn't find ANYTHING at this point that would warrant me wanting to return the TV, IMHO.
Moving on to blu-ray. I popped in a few movies and concerts and even with the sharpness set at 8, I couldn't duplicate the same problem I had experienced with the directv feed, even from my 6 foot vantage point. Graphics came out clean as a whistle and the picture looked absolutely stunning (again, thanks Mike

).
In conclusion, I found that this TV will correctly display what it is fed. Maybe there are some sets out there that do some kind of better job at cleaning up a bad signal but I would imagine there has to be some sort of trade-off and I don't have the luxury of trying out different TVs in a quest for perfection. Not that I'd want to anyway because I personally am quite satisfied with the picture presented. I think the old saying "garbage in, garbage out" applies here as again, the feed from the blu-ray looks absolutely fabuloso and the directv feed is still beautiful from my 12 foot position.
Hope this helps.
