I was at Best Buy last night where they had on display a Samsung 55" F8000 immediately above a Samsung 60" F7100. The F7100 had a noticeable amount of blurring compared to the F8000. I suppose the blurring could be related to Sharpness adjustments or Motion Interpolation settings. My feeling though was that the blurring was more severe than a simple adjustment. Perhaps it could have been the way the source was fed to the TV. The TVs were displaying the same video though. I also wondered if it was related to the TV size. The pixels must be slightly larger on the 60" and I don't know what design ramifications that brings. I guess there are too many unknowns to really say. I bring this up only to wonder if anybody has observed something similar. A 60" F7100 is about $900 less than a 60" F8000. I was thinking the F7100 might provide most of the image quality of the F8000 at a considerable discount. But now, I am not so sure. The video being displayed had one scene that was very striking. It is hard to believe two such TVs could display such a different picture. The scene was a view of a jungle, like something out of Jurasic Park. Here the F7100 might have actually looked better. The jungle vegetation looked lush. The F8000 had this really high sharpness about it making the vegetation look digitized. Other than this scene, the sharpness of the F8000 was always a big improvement.
