The Panasonic TX32LXD700 uses an IPS Alpha LCD panel, produced by the Hitachi- Panasonic-Toshiba joint venture. Going from the model I received to review (not all individual panels are created equal), there is a lot to like about this type of panel. For a start, the model I received featured a panel that is completely, 100% uniform. Showing a black screen revealed absolutely no clouding/mura defects or lighter/darker patches that so many panels from the Sony/Samsung S-LCD facility are plagued with. To someone who has returned three Sony W-Series TVs before getting one with a somewhat uniform panel, this was fairly astonishing.
Secondly, the viewing angle on the IPS Alpha panel is exactly as advertised – excellent. It’s all too common for the colours and contrast on LCD TVs to wash out significantly when viewed from any angle other than straight-on, but this is not the case here.
Unfortunately, the black level of the panel leaves a little to be desired, because Panasonic do not let the user manually adjust the light output (as previously mentioned). It’s at its darkest in “Cinema” mode, but even still the blacks here lean a little towards purpley-grey. I look forward to seeing a better-implemented IPS Alpha panel, inside a TV which allows its backlight intensity to be toned down further to alleviate this issue.
The Panasonic TX32LXD700 is fairly standard in terms of Video Processing functionality. In my tests, I found that, like almost every video device out there, it correctly activates 3-2 Pulldown Detection for interlaced NTSC movies. Like so many other displays, it can’t match this capability for 2-2 Pulldown Detection, so PAL movies –in other words, what most of our UK readers will be feeding to the display – suffered from the usual jagginess when input to the TV in Interlaced mode. This is nothing new, so as usual, I recommend pairing the 32LXD700 with a good Progressive Scan DVD player (like the Oppo Digital DV-981HD) and hooking it up over Component video or one of the TV’s many HDMI inputs, so as to avoid this common annoyance.
Video Deinterlacing was acceptable, but not exceptional. The jaggies test on the Silicon Optix HQV test disc showed that all three moving bars presented some degree of stair-stepping, which indicated that optimal smoothing was not being applied.
The quality of the TX32LXD700’s scaling was good, and the end result was really what I’ve come to expect from LCD TVs with a 1366x768 resolution. Standard Definition (576i) video fed to the TV over the Component and RGB SCART inputs had the usual mild ringing visible, which the TV did not appear to be artificially adding to. The ringing went away almost entirely when the all-digital HDMI connection was used to input 576p video, so I used this method.
With all of this in mind, it was time to gather some opinions on the TV’s picture quality in “real world” applications.
