Panasonic VIERA TC-P42ST30 42-Inch 1080p 3D Plasma HDTV

3D Technology Checklist

This product is 3D-related. To help you get a great 3D experience, use the checklist below to ensure you have everything you need. 3D viewing requires:

A Display
First, you'll need a 3D-ready display--whether it's a 3D HDTV, 3D projector, or 3D computer monitor. These displays have more processing power than standard 2D models for displaying 3D images in rapid succession.
A Source
Your display may be ready for 3D playback, but you'll still need a device to read 3D content. This can be a cable box with a subscription to a 3D channel, a 3D Blu-ray Disc player, or a PlayStation 3 system.
3D Content
3D content--the actual entertainment, in other words--will be played back using the source mentioned above, whether it's a 3D broadcast from your cable provider, a 3D Blu-ray Disc, or a 3D video game.
3D Glasses
For now, the vast majority of 3D HDTVs require glasses for 3D viewing. Many use powered "active shutter" glasses, others polarized "passive" glasses. You'll need one pair per viewer, and they'll have to be compatible with your display, whether they're the same brand, or a pair of "universal" glasses designed to work across brands.
HDMI Cable
To connect your source (such as a 3D Blu-ray Disc player) to your display, you'll need a high-speed HDMI cable. Cables with this designation feature bandwidth speeds up to 10.2 Gbps (gigabits per second), for carrying the 3D signal without any loss of quality.

If you want to get more information about 3D, shop our 3D products, watch videos, or interact with other customers, we invite you to visit 3D 101, our customer center about everything 3D.

Internet-Ready Television

Internet-Ready Television

Internet-ready TVs use your broadband connection to deliver dynamic content, whether it's streaming video from Netflix, new music from Pandora, or a quick glance at today's weather forecast.

Although there is overlap, each manufacturer offers a unique bundle of free or paid services, including streaming video and music, social networking apps, online photo galleries, news and financial updates, weather info, sports scores, and a variety of other smartphone-like applications.

Manufacturers continue to add new content to their offerings, keeping customers current through firmware updates, and making a bit of research a prudent step in your buying decision.

Learn more about Internet TVs, how they work, what services are offered by different manufacturers, and exactly what you'll need to get started at our Internet TV 101 customer center.

(March 2011)

Step into the 3D World. The VIERA ST30 Series Full HD 3D Plasmas create an all new viewing experience by putting you inside the action and creating a new world of TV viewing realism.

Infinite Black 2

In new VIERA models, contrast in brightly lit locations has been significantly improved. Enhancements to the panel and cells help reproduce images with smooth, natural gradation and deep, rich blacks even when viewed in bright surroundings. In movies, the true, deep blacks faithfully convey the intent of the filmmakers, adding power and realism to the viewing experience.

Full-time 1080 Moving Picture Resolution

VIERA plasma TVs have 1,080 lines of moving-picture resolution. Newly developed phosphors with minimal afterimages and a new motion compensating technology have made it possible to render faster-moving images with greater sharpness. This far surpasses the APDC moving-picture resolution measurement standard of 5 seconds by providing a moving-picture resolution of 1,080 lines at the 1.5-second level. And it shows the inherently clear motion of VIERA TVs in both 2D and 3D images.

3D 24p Cinema Smoother
VIERA incorporates technology that analyzes picture information in both the preceding and succeeding frames, and creates a precise supplementary frame between them. This suppresses the jerky effect seen in movies so playback is smooth and natural-looking. The distinctive tonal qualities and atmosphere of the movie are preserved, and you enjoy extremely lifelike 3D images.

Full 3D
Frame Sequential Technology

Panasonic uses Full-HD Frame Sequential technology to create its 3D images. Images recorded in 1920 x 1080 pixels for both the right-eye and the left-eye alternately flash on the screen at the ultra-high rate of 120 frames per second. When you view the screen through active-shutter glasses that open and close each lens in sync with the alternating images, you see breathtaking FULL HD 3D pictures with stunning power and realism.

Brilliant Luminance and Superb Blacks

By combining the highly light-transmissive IPS Alpha Panel and high-brightness backlight, Panasonic has attained both high contrast and low power consumption. Also, by detecting the contrasting parts of the scene, the backlight is adjusted to maintain a brightness that is optimal for each area. Deep blacks are reproduced with no fading. The contrast between the brilliance of diamond-like stars and the deep black of the night sky produces a sharp, crisp image.

600Hz Sub-field Drive

600Hz technology lets you view superb full-HD motion and still images. For even greater clarity with motion images, Panasonic uses its own unique image-analysis technology. This technology converts the motion in each scene into dots. And each frame is practically displayed for a shorter length of time than in previous systems, to reduce aftereffects.

3D Image Viewer

It's easy to view 3D photos and movies you shot yourself on the big VIERA screen. After shooting with your 3D-compatible camera or camcorder, simply insert the SD card into the slot on a 3D-compatible VIERA TV. The viewing is incredible, with images so realistic it feels as though you're right back in the moment. You'll find that life's special moments are even more memorable when you preserve them in 3D.


VIERA Connect

The exciting world of IPTV, centering on TV, is about to begin for the enjoyment of the entire family. Now you can enjoy intuitive remote control while relaxing on the living room sofa, with a wide variety of content at your fingertips. In the near future, TV will also be able to link with a tablet device to achieve completely new forms of entertainment that you've never before experienced.


VIERA Link interlinks the operation of a variety of AV devices, so you can operate them all using only the VIERA remote control. Setup is easy simply connect the compatible devices to each other via HDMI cables.

VIERA Remote

VIERA remote is a TV remote controller app for select Panasonic VIERA HDTVs that uses your iPhone/iPod touch/iPad (of iOS 4.2 or later) to control TV channel selection, input selection, and volume control. Included features are gesture control, a keyboard user Interface, and a power off button. Learn more about Panasonic’s VIERA remote app.

Long Panel Life, Up to 100,000 Hours

One important way consumers can protect the environment is by choosing high-quality products and taking care of them so they last for a long time. A high-quality VIERA HDTV can help. Thanks to a newly designed phosphor process and rear panel process, our plasma panels last for up to 100,000 hours before the brightness decreases by half. That's more than 30 years of viewing 8 hours a day.

Mercury and Lead Free Plasma Display Panel Panasonic is committed to making our products more friendly to the environment. In line with this commitment, all VIERA plasma display panels are free of both lead and mercury. This reduces impact on the environment years down the road when the TV is recycled or retired from use.

Verified Purchase
The picture quality of this television is really outstanding. It is however compromised by an issue common to all 2011 Panasonic plasmas known as "Fluctuating Brightness". About a half of a second after a scene change there is sometimes an instantaneous change in the overall brightness of the screen. Full discussion of this issue can be found by Googling: "panasonic 2011 fluctuating brightness".

Panasonic, to their credit, has recognized this as an issue and has come up with a solution that eliminates it. All sets produced after August and have a serial number of "xx1215xxxxxx" or higher will have new software installed that eliminates these brightness fluctuations from happening. If you have an earlier model and notice these fluctuations, contact Panasonic and let them know. They should either schedule a Panasonic employee to flash the software to your EEPROM, or they will schedule a 3rd party tech to replace your A-Board with one that already has the new software installed. In my case, they replaced the A-Board. Since then I have not seen any fluctuation and I am now completely satisfied with my set's remarkable picture quality.

Otherwise this television is exactly what I was looking for. Great price, superb picture quality, good Internet connectivity and interface. 3D is nice for future-proofing but it wasn't something I was actively looking for, but Panasonic sets with the best 2D picture quality are all 3D capable. Panasonic's menu interface seems a little more dated than their competitions, but it is simple and straightforward which makes it very functional without any extra eyecandy.

OK, I figured since I've hit the 200 hour mark I will give more impressions of my P42ST30.

I highly recommend D Nice's panel prep method which can be found online by using Google. Even if you "accidentally" watched a couple of hours of regular content, just start it now and don't watch anymore. I know that the purpose is to get even pixel aging for accuracy of settings, but I think doing this also results in sharper colors, with less bleeding.

I read the entire thread over on High Def Junkies forum about the brightness flux. Now I've been keeping a critical eye on this TV since I bought it (it's my 4th counting returns of 3 GT25's) and I had not noticed a problem with brightness adjustments during viewing. However, after reading the thread I decided to pay more attention. To test whether or not my TV suffered from brightness flux, I watched a movie that I thought would be an excellent test, Dark City on BD, Director's cut.

All I can say is that I was very impressed with how my ST30 handled this movie. If anyone is familiar with it, you know that Dark City is filmed almost entirely in this eery night/twilight background. There are tons of scenes with inky black backgrounds, brightly lit lights, and plenty of shadows and contours. This TV really passed with flying colors. I actually got up several times to go stare at the screen during a particularly dark scene with good contrast of bright localized lighting and I could not see any brightness flux, or any light bleeding into dark areas, etc...

Tried that "binary butterscotch" hi def jpeg that someone posted a video of on You Tube with his GT30 doing obvious flickering, and the only thing I saw was a very brief moment of darkening of the blacks in the picture and then it was stable.

I just received my TC-P42ST30 a couple of days ago. I haven't purchased 3D glasses yet so haven't viewed 3D on this unit, but regular 2D looks great, including 1080i HD. I did some tweaking to the picture and other settings and am still tweaking, but so far I'm very happy with the image quality. I'm watching the NCAA finals now - this unit is great for sports!

I'm not sure what another (negative) reviewer was watching to get a dark blurry picture with image lag - I'm getting a crystal clear picture on HD channels, and it's plenty bright and colorful after I tweaked the picture menu settings to my liking. I haven't noticed any motion lag, including during fast-moving basketball games. I found that the picture looked best with the brightness and contrast set between about +65 and +70 each. I also found that turning off "C.A.T.S." (a picture menu feature that automatically adapts image brightness based on ambient room light) in the picture menu keeps the display from darkening when I want it bright, so that might be worth trying while setting up the picture settings. I got the most realistic color by adjusting the color temperature to "Warm1" and using the "Custom" picture mode's "Pro settings" to tweak the white balance by increasing the blues (+10) and reds (+5) and decreasing the greens (-5) to get more realistic skin tones (I found it nearly impossible to judge skin tones by broadcast content - I used an image file from my computer as my color target) along with -5 on the general "tint" setting. I set the panel brightness to "low" and the gamma to 2.2. I also decreased the "Color" setting quite a bit (+40) to get the colors, which looked over-saturated on the default setting, more natural looking.
