UHD TVs Hit New Heights in 2019
Vizio’s P-Series Quantum LED UHD TVs
We’ve been talking a lot about video displays lately. I described a few luxury TV designs shown at the recent Consumer Electronics Show, and John Sciacca discussed the choice of front projection versus direct-view, highlighting the pros and cons of each.
If you’ve settled on a direct-view TV as your display method of choice for an upcoming home theater or media room, you’re now faced with the daunting task of choosing which one to buy. With prices that run the gamut from dirt cheap to “You want me to spend how much?!”, you might be asking yourself, is it worth it to pay more? What actually distinguishes a high-performance TV these days?
The truth is, even a budget LED/LCD TV can look really good for everyday TV watching and streaming. You can get great detail, solid image brightness, and relatively accurate color. Most budget TVs now have a 4K resolution and even claim to support High Dynamic Range—but there’s the rub. Budget TVs seldom have a high enough contrast ratio to really do HDR justice, and many of them can’t deliver the expanded color gamut that’s available in Ultra HD content. So when we’re talking about building a high-performance media system that brings out the best in your UHD source content—be it movies, games, or streaming—there’s a clear advantage in moving up the price chain.
LG’s Signature W8 “wallpaper” OLED UHD TV
Top-shelf TVs like Samsung’s QLED lineup, Sony’s Master Series of OLED and LED/LCD TVs, Vizio’s PQ Series, and LG’s OLED TVs don’t just support the input of an HDR signal. They actually have the contrast ratio to deliver a fantastic HDR viewing experience, and that begins with the ability to produce a deep black level.
OLED technology is the current standard when it comes to producing truly deep, dark blacks, but LED-based displays that use full-array backlighting with good local dimming can give OLED a run for its money. Most budget LED/LCD TVs don’t use local dimming at all, or the local dimming consists of so few dimmable zones that it’s ineffective.
High-performance TVs are also capable of much higher peak brightness, which is essential for reproducing bright highlights in HDR content. When we say an HDR TV can crank out 1,500 to 2,000 nits, we don’t mean that it’s doing so constantly with
every type of content—that would be painful to watch. But the beauty of HDR content is that the highlights in a scene—like the sun, the moon, or the burst of fire in an explosion—can be very bright, more akin to what our eyes can see in the real world. LED/LCD TVs still trump OLED in their brightness capabilities, but with OLED, the black level is so dark that the perceived brightness of HDR highlights is still fantastic. Budget TVs (and, frankly, front projectors) just don’t have the brightness capabilities to bring out the best in HDR.
One performance element that often gets overlooked is the quality of the TV screen’s anti-reflective filter. Especially in today’s multi-purpose media rooms, people don’t always watch movies in the dark, and a good anti-reflective filter is essential for rejecting the ambient light coming from lamps and windows to cut down on screen glare and preserve image contrast. High-performance models are usually better in this respect, too.
The final piece of the high-performance puzzle is the ability to produce the expanded color gamut in UHD content. A wide color gamut can be achieved in various ways. Quantum dot technology is used in many top-shelf LCD displays (it’s the Q in Samsung’s QLED and Vizio’s PQ) because of its ability to accurately and efficiently deliver the wide color gamut at the very bright levels required in HDR content.
Of course, performance isn’t the only thing people look for when designing a nice media room. Top-shelf TVs also tend to have nicer aesthetics, so you don’t mind looking at them
when the screen is off. They may be thinner and lighter, with more interesting bezel and stand designs. They may house the electronics/input panel in a separate box that’s more easily hidden away in a cabinet. They may integrate more easily with advanced wholehouse control systems. And they may have intelligent voice control and other user-friendly features built in.
Hey, a flagship TV is certainly not right for everyone. Most home entertainment enthusiasts will probably settle on something in between the low and high ends, and that’s OK. But for anyone looking to create the ultimate cinematic experience at home, there are plenty of reference-quality TV options to choose from this year.
