Blu-Ray:
Testing the U20 via a PS3 connected via HDMI and using the player's limited RGB settings. We played our favorite test disc "The Transformers (1st movie)", from chapters 18-24. The U20 delivered crisp visuals, with colors that are fine, vibrant and easy on the eyes. Motion Blur, pixel breaks and ghosting were not seen despite rapid mech transformations and high speed car chases. Flipping to the movie "The Underworld", we noticed that the U20's black levels are well laid out and generous. Shadow details remain intact despite the overly dark tones of the movie.
24p playback was "fair", given that mild screen flickers were still seen with this feature kept on. However, the issue is hard to see, and if you're not looking for them , chances are, you won't see the flickers at all.
"24p Smooth Film" and "Intelligent frame creation" are thankfully absent from this FULLHD panel. Those funky motion handling techniques actually do more harm than good. Having them "on" on my Panasonic V20 induced picture breaks that were totally unacceptable.
DVD:
DVD performance from a Pioneer 410v, was pleasant as expected from a plasma. I could not, however, see the advantage of a FULLHD U20 over the cheaper 720p panels like the C10 or the X20 in this area. If your primary purpose of upgrade is still geared towards this aging format. I suggest you stick to your 720p guns as the U20 won't yield any noticeable difference in picture quality.
Floating Blacks:
Neo-PDP panels I've had the pleasure of owning like the G11 and the V20 had an issue with sudden changes in contrast. Most seen during dark scenes, and so far the U20 did not exhibit any of these issues. Sure, when I put the U20 and the V20 together, you'd notice that the V20 has a more aggressive and a more vibrant over-all picture but one (esp like an anal person like me) can appreciate the more stable black level performance of the U20.
To be continued.
