Whats the difference in these Panasonic plasmas?

Question

Model TH-50PX77U and
TH-50PX75U

77 is more expensive...

Answer 1

According to CNET ...

We've got the TH-PX77U series covered, with full reviews of both the 42-inch TH-42PX77U and the 50-inch TH-50PX77U. In terms of design and features, the only step-up features are the side-mounted speakers, which add about two inches of width, and the antiglare screen coating. The antiglare coating might not sound like much, but we found it did a great job of reducing reflections in rooms with ambient light, without reducing image quality. Otherwise the feature set is nearly identical to the TH-PX75U series.
