  • Greyish blacks
  • Slightly reduced detail compared to LCD on 1080 material
  • Not as bright compared to LCD at high signal levels
  • Dirty screen effect (uneven screen uniformity)
  • Buzzing

If this plasma screen is any indication, the whole LCD vs Plasma war will probably continue for some years. Plasma technology has been developed longer than most of the newer, competing panels and it is clear that several clever innovations have kept it ahead in some areas concerning picture quality. We found that our model excels in accurate colour reproduction and video processing, making it well balanced to deliver the best SD and HD picture for your money. This is true despite its weakness in black level and panel resolution.

The upgraded Pioneer PDP-427XD uses a similar panel but differ in the following aspects:

  • 2 HDMI and 1 VGA connections
  • Picture-in-Picture
  • Subwoofer output
  • Universal Remote Control
  • Stand NOT included
  • ISF Calibration Service Menu
  • Slightly more expensive (about £100 more)

We recommend the PDP-427XD if you intend to employ professional ISF calibration service. You can still consider the PDP-4270XD if you want a set-and-forget plasma. Both should give very good pictures.
