Panasonic TC-P50GT30 3D Plasma HDTV
Price: $1,900 At A Glance: Good blacks and shadow detail • Odd gammas in Custom mode • THX certified • Uniformity and calibration issues
The GT30 line is the baby bear in Panasonic's range of 3D plasma HDTVs—not to expensive, not too bargain-basement, but, for many buyers, just right. And at 50 inches, one of today's most popular sizes, the P50GT30 lands right in the sweet spot. But does it offer more than Panasonic's entry-level ST30, perhaps even challenging the pricier VT30 lineup? We're here to find out.
The GT30 sports THX certification with six Picture modes: Vivid, Standard, Cinema, Game, Custom, and THX. Apart from the Custom mode, the settings for each mode are global and cannot be adjusted separately for each input. Separate settings for 2D and 3D are restricted to the Custom mode as well.
It also has a 2D-to-3D conversion mode and a Motion Smoother. The latter provides a three-position control (Off/Weak/Strong) that can produce more fluid motion, but it makes filmed content look wrong, as we often see with these features in LCDs. Fortunately, you really don't need this, as plasmas have inherently fast response times. That is, of course, unless you like the unnaturally oily smoothness this feature can produce. I don't.
For 24-frame-per-second material, the GT30's 24p Direct In setting gives you a choice of 48Hz (frames per second, with each 24fps frame displayed twice) or 60Hz, which is selected automatically for 60Hz progressive material or interlaced sources such as 1080i. It refreshes the image at 120Hz. (The manual mistakenly says this parameter can also be set to 96Hz, but it can't.)
Choosing 60Hz for 24fps sources adds 3:2 pulldown. Why might you do that? Flicker. Flicker was obvious and annoying on the GT30 in its 48Hz setting. To eliminate it, I used the 60Hz setting for all of my viewing, both 2D and 3D. Converting a 24fps source to 60Hz via 3:2 pulldown is normally considered bad form, but in this case, it produced no obvious artifacts. This didn't surprise me; I've done the same on reviews of Panasonic sets for the past few years (the 24p Direct In feature isn't new) and for the same reason.
The C.A.T.S. control alters the picture's brightness according to your room's lighting. But it's excessively aggressive; it limits the brightness to cataract level in a dimly lit or darkened environment. If one or more of the modes seems incredibly dim out of the box, check this control. It's probably turned on. Turn it off.
The GT30 can connect to the Internet directly or through your home network. You can connect wirelessly via Panasonic's included wireless LAN adapter, which plugs into one of the set's USB jacks. With this connection, Viera Connect (called Viera Cast on earlier Panasonic sets and on this set's remote) provides access to a growing number of Internet sites that Panasonic has partnered with, including YouTube, Picasa, Fox Sports, Amazon Instant Video, Netflix, CinemaNow, Twitter, Facebook, Hulu Plus, and Skype. By the time you read this, there could be more. For full Skype A/V operation, you'll need Panasonic's optional TY-CC10W camera ($170) or one of the alternate third-party cameras available. You can also see the images from a Panasonic security camera (not included) located anywhere in the house and linked to the set through your home network.
In addition, you can view still photos from your computer, full-motion images, and music through a connection to your home network or directly from a USB device or SD card. This includes compatible 3D content you may have captured on a 3D still or video camera.
As with most plasma sets, the GT30 has Anti Image retention features. These include a pixel orbiter that automatically and imperceptibly moves the image, an adjustment for the sidebar brightness on 4:3 sources, and a scrolling bar that can help clear temporary image retention (ghosts of images past) from the screen. As with all plasmas, a reasonable degree of caution with prolonged still images (or images that don't fill the entire screen) is advisable. There's no need to be paranoid about this, but it's smart to be extra careful during the set's first 100 to 200 hours of use. That's when the fresh-out-of-the-box phosphors are most sensitive to retention of fully stationary images, moving images with segments that don't move (such as scoreboards on sports broadcasts or video games), images that occupy less than the full screen, or particularly bright, opaque station bugs—here's lookin' at you, CNN.
After much head-scratching, hair-pulling, and mind-numbing back and forth on setup, I finally settled on using the Cinema Picture mode for 2D and the Custom mode for 3D. Custom is the only mode that provides user-menu high/low calibration settings for white balance (color tracking) plus multiple gamma selections and additional features.
