Value Electronics HDTV Shootout
Plasma and LED TVs face off for the perfect picture.

May 21, 2012 | by Grant Clauser

The first things we looked at were black level and contrast (closely related), which tend to be among the most important picture attributes in a TV. When you get good black levels, the picture looks deeper and more defined. Here the plasmas clearly had the advantage, though the Elite TV was also a contender. In fact, from the very first few images we saw, it was clear this contest was going to be primarily between the Panasonic VT50 and the Elite.

In color saturation, the Panasonic plasma also looked great, but I really liked the Samsung LED TV too. Coming in last in color was the Panasonic LED.

Next up was motion resolution. This was interesting, because LCDs can do curious things when their video processing features are engaged. In an effort to smooth motion, LCDs can create what’s come to be known as the “soap opera effect” which turns film-based material (like movies) into something that looks more like video (such as a soap opera). All efforts were made to defeat these processes.

All of the TVs looked good in the video resolution test, but the film resolution test showed a few issues. The Panasonic plasma and Samsung plasma appeared to shine here, though one test revealed bizarre artifacts on the Panasonic (not visible in any real-world content).

Once all the test patterns were finished, we checked out some movie clips to get a sense of the TVs’ real world performance. Here’s where things get interesting. On test patterns, all the issues, strengths and weaknesses were easily apparent, but when watching Blu-ray discs, you really had to be looking for trouble to see it, and even then, in most cases, any deficiencies weren’t drastic. A few of the TVs overall looked better than others, but none of them looked bad (remember, each TV had been professionally calibrated to its peak performance). A few of the enthusiasts in the audience remarked that they’d be happy with any of the TVs.

But, of course, a contest needs a winner. According to my score card, the Panasonic plasma VT50 came out on top, with both the Elite LCD and Samsung plasma landing in second.  Value Electronics posted the official winner (tallied from all the audience score cards) Monday, and awarded the winner’s title to the VT50.

So aside from knowing which of these six TVs came out on top, what else could be gleaned from this exercise? Throughout the evaluation, the calibrators would point out settings in each TV that would do bizarre and detrimental things to the picture—and in most cases these settings were promoted as features by the makers of the TVs. Artificial black level enhancements, edge enhancements, motion interpolation, dynamic picture modes and so on are all features promoted by TV manufacturers, but which go against producing an optimal picture. Most of those features can and should be turned off, and in fact some of them can be corrected quite easily by turning on things like THX or Cinema modes.

Because these sets were professionally calibrated, the image quality achieved won’t match what most buyers of these sets will finally end up with in their homes. I’d like to see a similar contest with TVs set up in the best consumer accessible modes—whether that be a THX mode or something else close. In fact, if I can get enough TVs into EH’s review lab, I’ll try that one myself and maybe invite some guest.

Also remember that this Shootout only measured image quality, and only in 2D. The factors important to your purchase decision may include other things such as connectivity, design, 3D, streaming content and price.

If you stop by Value Electronics, Zohn will show you the final score cards and let you know how each set fared and help you pick the best one for your home. Below are the final scores for the TVs

Exactly Ed, if if were that easy to duplicate the perfect picture, TV makers would put one button on the remote to change all the settings at once, and we’d all be done. So far the closest thing to that I’ve seen is THX mode, but it’s still not perfect for all models in all environments.

Unfortunatly as good as the sets today do calibrate. The accuracy of using settings between sets of the same model does not wotk out. Just from the standpoint of component cost alone. If you want the inter set accuracy where settings would work from one set to another the component cost that has that level of dependable accuracy would prohibit a set at todays pricepoint.

I cannot speak for the VT50 as it is too new. But back when we had a large # of VT30’s to calibrate we had the ability to save the ISF day/night settings and just dump them into the next set. I did not find one set where I could walk away happy with the measured values. It reached a point where I stopped wasting my time to upload the saved settings and just started from scratch.

But it’s the nature of a TV that the settings you put on it at 2,000 hours will be different from 10,000 hours, which is why a proper calibration is recommended every 6~12 months IF you want to keep it at calibrated standards.

There’s an IMAX screen close to me that is closed to the public, it is ONLY used to screen privately for IMAX family and friends events. There is an event usually every week-end. The screen and the audio system are calibrated each and every time.

@Calvin, if Robert Zohn posts the calibration settings, I’ll pass it on. Unfortunately, the calibrated settings do vary from set to set due to manufacturing inconsistencies and due to the viewing environment. In the case of these tests, we were in completely blacked out rooms, including black ceilings and boarded/taped up (with TV boxes) windows.

That’s great but the article would be better if the final settings on the TV of the winners should also be posted.  The true quality in my book would be if there aren’t such a wide variation of the settings in the same model of these TV.
