这是AVS FORUM里一位影音发烧友的评测,很详细,要耐心看!:loveliness: 重点看我加红加粗的部分!![s:19]
Hello everyone,
I decided to post my own review of the
Panasonic 3D products
I got last week: the Viera
TC-P65VT25 3D plasma
display and the
DMP-BDT350 3D Blu-Ray player.
I wanted to write an honest review that’s comprehensive and accessible to everyone, since we are not all professionals in the A/V world. Plus, I like user reviews as they are not biased like many professional reviews out there.
My review is for the Canadian and American versions of the products, but should still apply to all other parts of the world in general, except a couple of different settings.
I have owned many televisions in the past to compare this set to, including:
- Sony Trinitron Grand Wega 32” CRT
- Toshiba Cinema Series 56” DLP
- Samsung PN58A650 58” plasma
- Samsung PN58B850 58” plasma
- Panasonic TC-P65VT25 65” plasma (my current TV)
Also, my brother owned a Sony XBR4 52” LCD that he just replaced for a Samsung UN55C7000 3D LED TV so those are two other comparison units that I used in this review.
Panasonic Viera 65 inch 3D plasma display
(model number TC-P65VT25):

The Panasonic TC-P65VT25 retails for 5000$ CDN (or 4300$ USD in USA).
Styling:
It’s a standard yet classy glossy-black bezel and the VT series adds a hint of bronze in it to distinguish it from lower-end series in the line-up. Overall, it’s a simplistic design that has clean lines but lacks elegance like other sets on the market, for example the sensational ultra-slim “Touch of Color” designs by Samsung. The Panasonic 65-inch set is 3.6” thick and weighs in at a hefty 120.2 lbs with stand (105.9 lbs without stand). Although it’s clearly not the best looking TV on the market, you can still tell it’s a quality piece that is well assembled. My set was assembled in Mexico, as all of the VT25s are.
Connectivity:
The set comes loaded with pretty much any type of connection you would need:
- 4 HDMI ports, one located on the side of the panel
- 2 USB 2.0 terminals
- PC input (VGA)
- RS232C input
- Ethernet port
- SD card input
- Component analogue interface
- Composite video RCA jacks
- Headphone jack
- Access to Viera Cast online
- Wi-Fi ready
Menus:
This set is both THX and ISFccc certified for anyone who would like their sets professionally calibrated. The menus are easy to use, although some features might seem complex for first time Panasonic buyers: features like “Mosquito” noise reduction and “C.A.T.S.” automatic brightness level adjustments. The options are well explained though and are easy to use. Once again, the styling of the menus isn’t revolutionary; it’s actually plain-looking. It’s the standard Panasonic blue and yellow menus. I would have liked something more futuristic looking perhaps.
Modes:
There are different viewing modes to choose from: vivid, standard, THX, game, and custom (which gives you access to the Professional settings). When viewing 3D content, THX mode becomes “cinema” mode. I guess it’s because there hasn’t been an established THX certification for 3D content yet, hence the change of names. I found the THX mode to be quite good out of the box for Blu-Ray or DVD watching, but a bit too warm in color tones when watching TV broadcasts. I prefer to use my custom mode for general viewing.
Processing:
This set has all the bells and whistles one could want in the picture processing department, including 24p cinematic playback. You can choose between 48Hz, 60Hz and 96Hz refresh rates. The latter is the one I selected since it’s the one that gives the least amount of flickering and is a direct multiple of 24. Yes there is a very subtle flickering present when watching Blu-Ray movies at 24fps, but it’s very acceptable. For those of you who aren’t sensitive to flickering, you probably won’t even notice it. But it is present, although in most movies, you really can’t tell. Overall, the smooth camera movements and judder-free video feed is great.
2D Picture performance:
The set’s specifications call for a 5,000,000:1 native contrast ratio thanks, in part, to the NeoPDP panel and to the Infinite Black Pro filter. I can’t say that the contrast blew me away when compared to my previous high-end Samsung PN58B850 set, which had great colors and a 3,000,000:1 dynamic contrast ratio (1,771:1 full-on/full off ratio). Both sets have great colors and great contrast. The set also has a 600Hz subfield drive and has a moving picture resolution of the full 1080 lines. There is no apparent motion lag. This has to be the quickest refreshing set I’ve seen out there. Everything is smooth and judder-free. High definition is razor sharp on the VT series. You would be hard pressed to find a TV with a sharper picture on the market.
For normal standard definition tv broadcasts, I wasn’t impressed with the overall performance of the VT series. I preferred my previous Samsung 8-series plasma for SD viewing. The picture processing for SD is superior in many other sets on the market. But feed the VT series a good clean HD signal, and that’s when it comes to life.
One thing that is clearly obvious is that the Panasonic has an amazing black level performance! I was blown away by how deep and inky the blacks are. Professional measurements have reported anywhere from 0.002 to 0.009 out of the box black levels. It’s far superior when compared to my previous Samsung 8-series plasma which measured a reported 0.020 black level.
I’ve seen a Pioneer Elite Kuro PRO-141FD 60-inch panel in person and I have to admit that the boasted 0.001 black level is true. The Elite plasma does produce slightly deeper blacks, but only in the darkest environment. In daytime viewing, or at night with background lights on, you can’t really tell the Elite from the Panasonic apart as far as black level performance. Keep in mind that the Elite sold for almost 7,000$ CDN (although discontinued, there was one store chain in Montreal that had some left in stock back in April). One thing is for sure, the Panasonic VT series has the deepest black levels from any 2010 sets hands down.
There has been a lot of talk about the “floating blacks” and rising black levels issues on 2009 Panasonic sets. Although speculations continue, I haven’t read any reported issues with 2010 series plasmas to date. Panasonic has admitted to the previous year’s issues and state that they have “corrected” the black levels rising issue through software modifications. There will still be rising black levels, but they will be much more gradual throughout the life of the panel and shouldn’t be visible to the end user.
Viewing angles are perfect on this set, as they are on all plasmas. That's just one of the advantages of plasma display technology. I also found the anti-reflective filter to be quite good, on par with the one on my previous Samsung 8-series plasma in my opinion. My TV is right next to two big patio doors that lead to my exterior balcony and even during day time viewing, much of the light is filtered out. Yes you still see reflections, but not as badly as cheaper sets with cheaper AR filters.
3D Picture performance:
I’ve seen plenty of 3D TVs with 3D demos: Samsung 7000 LED series and Sony HX900 series which were on demo at the Montreal Audio/Video show back in March, and the Panasonic VT series which I had first seen on demo in a Magnolia/Best Buy store in New York at the end of April.
First of all, each VT set comes with one free pair of 3D glasses. Users of those glasses share different opinions. In my case, I found them of higher quality than the Samsung ones. I don’t really find them heavy, but many users have complained about this. The only thing I don’t like about the glasses is that the sides are open, letting light in a bit and perhaps distracting the user from really enjoying what’s in front of him. But for night viewing, which is when I watch my movies anyways, those glasses are great. They have a small power button on the side that you use to sync the glasses with the panel. When you’re done, either switch the power off or simply put them in their case and they’ll switch off automatically.

And contrary to alot of rumors on the net, the glasses work fine beyond 10 feet. I am seated at exactly 14 feet away from my TV and the 3D signal is fine. No worries there.
It’s 100% a Panasonic victory in the 3D department. Panasonic really has the best 3D performance of all sets available. Hands down. Colors are popping, there is great depth to the picture, and most important of all, there are no ghosting (also known as cross-talk) or motion blur issues thanks in part, to the new short persistence phosphors developed by Panasonic specifically for the VT series and of course, to the fast response of plasma technology overall.
I found myself enjoying the 3D experience quite a bit. I preferred the home version of 3D in comparison to what theatres like IMAX have to offer, which usually consists of a dimmer image lacking color and punch. Even if we are in the earlier stages of home theatre 3D, I can still say I love the technology. And Panasonic has the edge over its competitors in that department.
Energy consumption:
I have to go with the measured stats for this one. The set is Energy Star 4.0 compliant. It’s quite obvious when using the standard viewing mode, because I found the picture to be unusually dim in that mode; I guess it’s in order to meet Energy Star requirements. A 50-inch VT series set will use 140 watts in 2D and roughly 170 watts in 3D (both using standard mode). I haven’t seen numbers for the 65-inch version yet. But it will surely be less than my previous Samsung 8-series 58-inch plasma.
Other comments:
The set does generate a bit of heat, but nothing unheard of in the plasma world. It generates a bit more heat than my previous 8-series Samsung, but alot less than my older Samsung 6-series plasma. Also, I read alot of people complaining about plasmas "buzzing". I do hear the buzz if I'm standing under 2-feet close to the set, but other than that, I hear nothing major. My 8-series Samsung buzzed alot more than the Panasonic for sure.
Conclusion:
I will let each of you pull your own conclusions on this set, but personnaly, I have to agree with other reviews that say that the Panasonic VT series do 2D brilliantly in both dark and bright viewing environments and they can also produce an enveloping 3D experience as an added bonus. That says it all.
*********************************
Panasonic DMP-BDT350 3D Blu-Ray player:

The Panasonic DMP-BDT350 Blu-Ray player retails for 600$ CDN (or 430$ USD in USA). It replaces my previous player, the Panasonic DMP-BD60. I’ve also owned a Sony Playstation 3 in the past (40GB version).
Styling:
There isn’t much to say in the styling department other than it’s typical Panasonic: simple and clean lines. It’s a bit bulkier than the previous BD60 series, but overall build quality is great. It’s a very sturdy unit and connectors in the back are high-end.
Features:
There are a couple of new features on this unit, including HDMI jitter purifier to help clean out digital signals and a feature called “digital tube sound” to give music a warmer feel just like tube amplifiers do. I’m not so sure I can tell the difference over the BD60 unit, which was a great BD player as well.
Of course, picture and sound quality are almost perfect on the DMP-BDT350, almost on par with the much acclaimed Oppo BDP-80 player. Of course, this player supports 24p cinematic playback.
Performance:
The main thing I noticed with the new Panasonic unit is how fast it is. Boot up times and load times have greatly improved over the previous generations. It’s not as quick as the PS3 or Oppo yet, but it’s closing in nicely on the gap. Boot up time is super quick especially when “quick start” mode is activated. Loading Avatar took roughly 30 seconds less than with the BD60, although I would have to measure the actual times using a chronometer. Also, browsing through menus is quicker and feels smoother than previous generations.
2D performance is as good as it gets from any Blu-Ray player out there. The UniPhier chip does an outstanding job of processing signals and even has great upconverting qualities. Standard DVDs will shine with this unit. Plus, Panasonic has always been known for great sounding disc players, and this one is no exception. We can almost qualify it as an audiophile grade unit. It plays high-end music very well and gives out natural sound. Although I mostly listen to hip-hop, I like taking time to enjoy high quality recordings like Acyntha, Happy Coat, and the classic audiophile music in the likes of Norah Jones and Diana Krall. And the Panasonic unit does not disapoint.
Wireless internet capabilities:
The Panasonic DMP-BDT350 player comes with a free wireless LAN adaptor (or dongle as they call it) for wireless internet hookup. I bought a Linksys WRT160N wireless-N router to set up a network. In less than 20 minutes, the whole thing was set up and I was surfing on Youtube from my Blu-Ray player’s Viera Cast.
I have experience with computers, but I still believe an average person should be easily able to set up their wireless TV and Blu-Ray player because honestly, I had practically no work to do. Here are the basic steps I followed:
1) I hooked up the wireless router to my cable modem, and ran an ethernet cable from my router to my PC. I ran the automated setup disc that came with the router, and in a matter of minutes, my wireless network was up and running. I used WPA2 for security, as this is the highest level of security and encryption you can get.
2) I took the Wi-Fi dongle, plugged into the Blu-Ray players USB port. Powered everything up, and ran the wireless setup menu. In under 30 seconds, the network was recognized and was up and running. I did a firmware update, and there was version 1.40 available.
3) I powered everything off, unplugged the Wi-Fi dongle and plugged it into the TVs USB port. I powered everything on and ran the TVs wireless setup. Same thing again: in under 30 seconds, the network was recognized and was up and running. I did a firmware check and I had the most recent firmware 2.00.
That’s how easy it was. And wireless performance is great both on Blu-Ray player and the TV. I get a perfect signal and my router is in another room (and I have a big 1260 sq.ft. condo). That little dongle is a keeper! Great addition Panasonic! And it was free.

3D picture performance:
3D is great with this unit and the VT plasma! I have an HDMI 1.3 receiver for my home theatre, because I’m still waiting for Integra to release their DTR-70.2 HDMI 1.4 receiver later this summer. Although my current Marantz SR-5003 receiver can’t process the 3D signal (you need an HDMI 1.4 receiver for that), there is still a work-around thanks to the DMP-BDT350’s dual HDMI outputs!
I have Monster Cable 1000HD series cables (their most high-end) which are 1.3 rated, but basically are rated for greater than 15.8 Gbps of bandwith, which is the same as HDMI 1.4 cables will offer. The only thing HDMI 1.4 cables add, to my understanding, is an ethernet cable and an audio return path, both features not needed in my case. So your high-speed HDMI 1.3 cables should be good enough.
Here is how to use your DMP-BDT350 player with an HDMI 1.3 receiver:
1) I ran one HDMI cable from the “HDMI Main AV out” terminal straight to my TV.
2) I ran a second cable from the “HDMI Sub AV out” terminal to my receiver.
3) The instructions on page 10 of the owners’ manual said that I had to set HDMI Sub output mode to “V.OFF.” in my Blu-Ray menu, which I did. At that point, the “V.OFF” light turns on in the front of the Blu-Ray player.
Bingo! I loaded the Panasonic 3D demo disc (that comes with the Blu-Ray player) and I had FULL 3D HD. Everything worked great. And you still get the DTS-HD MA or Dolby TrueHD soundtracks when playing 3D movies this way. Great workaround Panasonic! So I get to enjoy all the bells and whistles 3D has to offer until I get my new HDMI 1.4 receiver.
Update: I just received my copies of 3D Blu-Ray movies on June 10th. I'll be watching those this weekend (Coraline 3D and Ice Age: Dawn of the Dinosaurs 3D). They are in the Panasonic Canada promotion for purchasing the 3D TV + 3D Blu-Ray player combo. (In the US, you only have to purchase the 3D TV to get those movies... check out the promo here:
http://panasonic.com/promos/3d-blu-r...0May%2017%20AM).
So there you have it folks, an in-depth review of both the TV and Blu-Ray player.
I hope you’ve enjoyed reading it.
P.S. For those wondering, here is my complete HT setup:
- Marantz SR-5003 receiver (to be replaced by Integra DTR-70.2 when available)
- Panasonic TC-P65VT25 65 inch plasma TV
- Panasonic DMP-BDT350 Blu-Ray player
- Totem Mite-T front speakers
- Totem Mite-T center speaker
- Totem Mite rear speakers
- Focal Chorus SW 800 V subwoofer (to be replaced by SVS PB12-Plus subwoofer as soon as they resume shipping on July 7th due to backorders).
- Monster Cable 1000HD series HDMI cables
