Panasonic TH-42PZ80U Plasma HDTV

Impressions Round-Up:

It’s impossible to quantify an absolute opinion on Panasonic’s TH-42PZ80U without first considering the outstanding price.  Thinking back two or three years, it’s incredible to consider what $1,300 can net you now in the television market– 40+ inches of screen, 1080p resolution, and solid specks to boot.  The TH-42PZ80Umakes the most out of this investment, as it provides a gorgeous image for gaming, film, and television sources.  Color levels and high-definition “pop” really accentuate how sumptuous this set can look under the proper conditions.  The 20,000:1 contrast level also serves itself well here, crafting stark black levels and fluctuating palettes that adjust with its sources well.  When compared with other strong-performing HDTVs in the size and price range – such as the Toshiba REGZA LCD series and several Sharp models – it renders black levels with deeper, inkier substance, while fighting tooth-and-nail to parallel them in detail and color range.   Matched with two rear HDMI ports and one to the front, it’s got enough inputs to use without seeming like overkill for receiver-using individuals.  Along with that, the set seems built for a mid-sized room (tested in a room roughly 13x13), as the viewing range is extremely wide at around 150-155 degrees without any ugly internal screen reflections.  Plus, it’s an attractive addition to any room, sporting a beautifully designed chassis that looks a lot pricier than it really is.  

The TH-42PZ80U ’s attractive looks can also be a slight deterrent, as the glitzy gloss picks up any form of light that pours into the room.   Along with that, there are only a few negatives to attach with the set’s overall performance.  As with Panasonic’s past plasmas, two picture issues arise that you had to adjust to while warming to the PZ80U: green trail, and a mild red push.  The green trail grows less noticeable with your time with the set, though it still becomes strongly apparent in high-motion instances in films, television shows, and especially games.   But it remains to a mild degree, something that drove me mildly crazy as I followed the Wii’s hand pointer around on-screen.   With the red push, it’s an element that renders slightly embellished pinkish-reddish skin hues from time to time, depending on the source.   Picture adjustment can handle a large portion of it (lightly adjusting the tint with some color guidance), but it’s a necessary evil to preserve natural shades with the rest of your colors.  Now, regarding image retention, it’s an omnipresent concern when considering a plasma television purchase – one that the PZ80U suffers from to a certain degree.  No damage could be discerned from the numerous hours of testing that the set underwent, but bits of mild retention could be spotted – and rectified, once the source either reset internally or shifted to another feed.  Also worth considering is the fact that the PZ80U doesn’t contain either a PC-input or the heightened 30,000:1 native contrast ratio like its slightly more expensive brother, the TH-42PZ85U, or THX certification like its near-identical twin, the TH-42PZ800U.  

Given the value underneath the hood of the sub-$1,300 Panasonic TH-42PZ80U’S , it’s a wholly worthwhile purchase for those in the market for a 42” 1080p plasma television set.   Some might argue that the screen size doesn’t quantify a necessity for the higher-resolution progressive technology, but that will actually depend on visual sensitivity for the viewer and sitting distance from the set.   Still, the ability to handshake more aptly with sources at the 1080p setting gives this set an extra boost over 720p alternatives, all the while providing a substantially solid image that concentrates on contrast differential and color saturation as its key assets.   Panasonic continues its legacy of being one of the best budget-minded plasma producers around, crafting an admirable piece of equipment with their TH-42PZ80U that fits the bill for anyone shopping for a mid-range 1080p set.   Some might want to consider the TH-42PZ85U for its additional boost in contrast ratio and PC-inputs for an extra $100 or so; but if computer integration isn’t an issue, then flip for a few classy Blu-ray discs – or even a player -- to watch on this gorgeous plasma instead.

Allan Sonac  - Panasonic 42" 720P a better deal   |2009-01-27 16:30:55
First off I agree for the most part with your assessment. However if someone
were to want to save even more money and IMHO get a better viewing experience
overall I would go with the same TV except the 720P version.First Up here in
Canada, no one is broadcasting 1080P, it's either 1080i or 720P second there are
only a limited amount of HD broadcasts, third DVD's and SD and NTSC look better
on the 720P TV rather than the 1080P TV. Fourth most Blue Ray movies although
the packaging says 1080P are really 720P. Therefore for the 1% viewing that
you're going to do a 1080P (BD) you're lible to sacrifice the other 99% by going
for a 1080P TV. Also what you fail to mention in your article is that Panasonic
Plamsas are not true 1080P...you don't get 2 times as many pixels...what they do
is actually a trick, they use software to take the same number of pixels and
divide them in half to give you the impression of having 2 times as many pixels
as a 720P TV instead you end up with less light per pixel by doing that...so the
1080P TV's are not as bright. Remember garbage in garbage out! If you're source
is cable TV even on the digitalHD box the rez is only 250K pixels...that means
that a true 1080P TV has to multiply the pixels by almost 10 times to give you a
picture!

Allan, I agree with you that there is very little content now available in
1080P. However, if you are correct (and I believe you are) about the pixel
count on this Panasonic 1080P plasma, one should apply the same analysis to the
Panasonic 720P plasmas, which in terms of pixels are actually less than true
720P!! They are only at XGA resolution, which is why I have not purchased the
720P versions.
Allan Sonac  - Resolution vs Speed   |2009-01-28 06:33:32
Hi Rich,
Actually the 720P Panasonic is a true 720P...You can't just base your
evaluation on Pixel count...you need to look at the number of pixels that are
being sent to the the TV and the way that TV interprets the pixels and displays
them. Refresh rate, pixel display speed and pixel fade speed have a lot to do
with this too. Most Plasmas are much like our old CRT displays. The refresh
rates are very high...typically 240 HZ. These sets are capable right out of
displaying 24 FPS DVD content unlike a lot of LCD and early RPTV's. Most LCD
TV's still have slow refresh rates of around 60 HZ...24 does not divide very
well in to 60...that's why the newer ones are available at 120 and 240.
Panasonics now go up to 480! The pixel speed of a Plasma is much faster than
that of an LCD.
Allan Sonac  - Part 2   |2009-01-28 06:46:22
Most of the current LCD's bigger than 37" have difficulty displaying true
HDTV resolutions while displaying fast action such as sports of Action movies.
Images are generated accross the screen (example:left to right) instead of top
to bottom (old crts). While trying to display the image the LCD technology can
not keep up with the demands on image refesh speed and the resolution drops down
to well below HDTV standards...most people do not know this. Sony and now Sharp
have come up with newer technologies such as those on the Sony XBR that display
true HDTV in these situations...however at a cost significantly higher than
plasma. Most good plasma tvs do not drop down in resolution while displaying
high speed images. On the other hand the 1080P Plasma that you reviewed rely on
software that is not as efficient at displaying rapid video content at 1080P as
the 720P TV as dividing the pixels creats other problems. When you divide the
pixels your refresh rate now drops in half.
Allan Sonac  - Part 3   |2009-01-28 06:47:40
When you divide your pixels in half your refresh rate divides in half too.
Allan Sonac  - Part 3 cont   |2009-01-28 06:53:13
Therfore if you were to actually compare for example an HDTV broadcast,
especially fast moving sports such as hockey or a DVD (and most action movies on
Blue Ray)the image will be clearer and sharper on the 720P TV. Just try a double
blind test using the same content with the same group of people on the two
technologies....

I have had this set for about two months and have been extremely happy. Another
thing that is not noted is that this set can be had for under $1000. I use it
as a second TV in a loft area. I watch BluRay and play PS3 games as well as
watch HD content regularly. I set within 6 feet and this set in real world
situations is a great set.

Alan,
This actually isn't correct, although I admit it is confusing. A 1080i
and a 1080p signal are capable of displaying EXACTLY the same number of pixels,
2,073,600... (which is more than 2X the 1280X720-60)the difference is in how the
screen is refreshed. But its crazy to get a 1080p set smaller than 50"
unless you sit withing arms reach of it.

just purchased this tv for my master bedroom at hhgregg for $629.00 +TX and have
a ps3 and xbox 360 hooked up along with a dtv hr700s hdddvr+micro pc quad
corecore @2.9ghz.2tb hdd ,Zotac ZT-95tes2p geforce 9500GT @512mb 128bit
ddr3 media center via hdmi and i have to say for price and features this is by
far one of the best tv's i have ever owned gaming at1080i 1080p pictures res is
awsome with some trailing in heavy areas watching media off pc is a pleasure
also bluray disc's are incredible clear sharp and fluid even with fast motion
sequences only real con was the speakers built in are not the greatest (but ive
yet to find a plasma tv ive owned that had exceptional sound out of box)very
hard with bass sounds whaffing out but with my new panasonic SC-PT960 HT 5.1
@1250watts was a instant fix .all in all i give this tv an9/10 video
6/10sound and 10/10 for price if your looking for your next new tv look no
further

Bought the TV and I love it. 1080p i 720 and so on. I guess they matter but
compared to my 32" cathod model I'm loving it. Just goes to show I guess, I
picked the plasma over the LCD for that I took a ribbing. I love the Picture nad
the features. Enjoy the TV for 1408 I got a deal
