A Guide to Luxury Video Displays

What is a Luxury Entertainment System?

In our first Cineluxe Basics post—”What is a Luxury Entertainment System?“—we provided a 30,000-foot overview of the basic components that go into building a modern AV system. The goal there was not to overwhelm you with technical specs or particulars, but rather give you a general understanding of what bits you need when having a luxury system specced and installed for you.

 

As promised, though, we’ll now start digging into the specifics of each type of gear, for those who want a deeper understanding of the technology and a better sense of what makes a component suitable for a luxury environment and a world-class home entertainment experience.

 

First up: Video displays (aka TVs). As mentioned in the overview, you should first decide what type of screen you want or need for your room. Your main two choices are between a TV or a projection system with separate projector and screen. (But there is a third option emerging, which I’ll touch on in a bit).

 

If you’re building a dedicated home theater, or if for whatever reason you simply want or need a screen larger than 85 inches, a projection system may be your best bet, for all of the reasons John Sciacca details in “Basic Choices: Projector or TV? Pt.

1.” If you’re building a media room or multi-use space, though, don’t let anyone talk you out of a high-performance TV. Today’s best Ultra HD (4K), HDR-capable displays deliver a level of visual excellence that’s hard to match with any level of projector/screen combo. You’ll get deeper and truer blacks, more spectacular highlights, richer and more lifelike color, not to mention that TVs generate much less heat and noise.

 

“What about the sense of scale, though? The wow-factor? That wall-filling spectacle of it all?” I hear you asking. Truth be told, all of that is really determined not purely by screen size but by the relationship between the size of the screen 

and the distance to your seat. Park yourself six-and-a-half feet away from a 75-inch TV, and you’ll enjoy the same IMAX-like viewing experience as if you sat ten-and-a-half feet from a 120-inch screen. Depending on the size of your room, that may also leave enough space behind you for a more immersive surround sound experience.

 

If you’ve paid any attention to the TV market as of late, you’ve noticed that there are hordes of high-performance, 75-inch and larger UHD TVs ripe for the picking. But would they all be at home in a luxury entertainment space? I argue not. What sets luxury TVs apart isn’t merely their specifications, but rather their industrial design

That’s why I think something like Sony’s XBR-75X950G (shown above) is the starting point for luxury. At $3,300, this TV offers excellent performance, but perhaps more importantly, the X950G sports a simple-yet-stylish design you won’t be embarrassed to hang on your wall or place on the credenza in the living room. It also features niceties more economical TVs lack, like integrated cable management, so you can keep your installation neat and tidy.

 

Step up to something like Sony’s Master Series displays and you do get a bit of a performance boost (including 8K resolution at the very top of the line). But just as importantly, you also get sleeker, more innovative designs, ensuring your TV will look just as good when it’s off as it does when it’s on.

If these models are still a little too “TV-like” for your tastes, LG will soon be introducing a pair of OLED displays that break traditional design molds. The company’s OLED88Z9PUA (shown at the top of the page) eschews the standard pedestal for a built-in open shelf that creates the illusion of the TV floating in mid-air. Its upcoming R9  

OLED, meanwhile, turns the screen itself into a rollable element that retracts into an elegant speaker console when not in use. The screen can also peek out of its hidden home to give you a quick look at the weather, the time, or the particulars of the music you’re currently listening to.

 

Of course, we can’t talk about innovative TVs that break all design molds without mentioning Bang & Olufsen. You may remember B&O from its iconic BeoSound 9000, a radical wall-mounted CD player that practically defined Danish style in the mid 90s, or perhaps you have a B&O sound system in your BMW or Audi. But the company also makes some of the most

gorgeous displays we’ve ever seen. The Beovision Eclipse is a high-performance 4K HDR OLED TV with a built-in 450-watt sound system and an incredibly versatile motorized mounting system. This fall, though, the new 77-inch Beovision Harmony will take things even further with a stunning three-channel speaker system that unfolds from the front of the display like a piece of kinetic origami.

The bottom line is that any display you add to your luxury entertainment environment should enhance, not detract from, the décor. And there are plenty of options that do exactly that. But as mentioned above, there’s another display option that is neither TV nor projector.

Samsung’s MicroLED “The Wall”

Video walls are starting to make their presence known in luxury AV installations in a big (huge!) way. Granted, in the past, such walls were constructed by butting smaller displays up next to each other and splitting an image across them. Today, though, MicroLED technology from companies like Planar (and soon Samsung, LG, and Sony) allows installers to build larger and larger screens out of modular components that can fill a wall from top to bottom with seamless 4K or 8K imagery. No lines. No stripes. Just vibrant imagery with no boundaries.

 

For now, this technology is mostly aimed at commercial applications. But Planar has already had great success in the luxury home market, and as companies like Samsung, Sony, and LG bring their own MicroLED modules to the market, you can expect to see them become more common in the home.

Video Displays: How Good Is Good Enough? Pt. 2

video display innovations

The Avatar sequel is reportedly being shot at 120 frames per second—5 times the
frame rate of the traditional 24 fps.

In Pt. 1, I discussed how improvements in color space and dynamic range are bringing video displays closer to the abilities of the human eye. Here I’m going to discuss the impact of spatial resolution and refresh or frame rate.

 

Pixels get all the attention when most people pick out their TVs. 2K, 4K, 8Khow many K’s do I need? But just because a display can put more pixels on the screen doesn’t mean they’re better pixels. 

 

Everyone has had the experience of going to the eye doctor and straining to see if that E is pointing up or down, or left or right. As you go from the top line to the bottom, there’s a point where you can no longer determine which direction the E is pointing. This is how the eye doctor determines your sensitivity to spatial resolution.

 

My eyes aren’t quite as good as they used to be, but on a flat-screen TV, I can see pixels on a 1080 display when I’m standing about 3X the picture height back. On a 4K, I can’t see pixels until I get inside of 1.5X the screen height. With projectors, you need to be even closer to see pixels as a result of the natural smoothing affect of convergence and optical lenses.

 

If I’m staring at a spreadsheet, those pixels and distances are pretty accurate, much like staring at those E’s at the eye doctor. But if I’m watching a movie, I’m not straining my eyes to see pixels but instead want to take in the whole image, so I’m moving further back. 4K allows me to sit comfortably about 2X the screen height back, which is as close as I’d ever want to watch a movie. So for the future, don’t give me more pixels, give me better pixels!!!

 

So far, I’ve been talking about pixels, but unless I’m only talking about spreadsheets, I need to understand more about how the human eye sees motion. After all, I want to watch movies!

video display innovations

James Cameron, of Avatar fame, was one of the first Hollywood producers to push HFR (high frame rate). The original movie spec was 24P, and it was chosen because it was the lowest refresh to allow acceptable audio quality. This means that the entire image on the screen is refreshed 24 times per second.

 

If I’m watching two people sitting across a table from each other talking, slow frame rate doesn’t bother me. But if I’m watching a plane fly across the sky, or Matt Damon jumping from one building to another in a chase scene, I need faster refresh rates. When you look in the sky and see a plane fly by, you see it move in a nice, smooth continuous motion. But when you watch a movie in 24P, the plane will seem to jump across the screen as it moves from frame to frame. Your brain naturally tries to smooth this out, but when you watch two scenesone with HFR and one withoutyou appreciate the difference.

 

The critics say HFR makes images seem “soap opera”-like, but honestly, isn’t that the way we see things in real life? When we walk through everyday life, does the world look more like a soap opera or a movie? (I did say “look” and not “feel.”)

 

So currently we hover between 24P for movies, and 60P for video. Experts seem to feel that the threshold for the human eye is around 120Hz (which is what the Avatar sequel is rumored to be shot in). Let me please note that HFR means the movie or content was shot or captured in this high frame rate, not just displayed at faster refresh.

 

Many flat panels tout 240Hz or even 600Hz refresh, but that is just refreshing the same content on the panel and is intended to fix deficiencies in the panels, not in the quality of the movie. HFR requires a lot of bandwidth, so improvements here are costly, but they have a big impact on the way we see images. So expect this to take a little longer than the other items discussed here.

 

In the past 10 years, we’ve seen improvements in all aspects of display performance that affect visual acuity. In the next 10 years, we will see even more improvements. The most important thing is that it’s not just about resolution. Getting to 8K will not bring us to the ultimate display.  In fact, most people won’t see any improvement from going from 8 million pixels to 33 million pixels. If we all want to watch video and have it replicate real life, we don’t really need more pixelswe need better pixels. Give me pixels with more color, more contrast, and refresh them on the screen faster. In the meantime, give me content that will really take advantage of all that my current 4K UHD display can handle.

Video Displays: How Good is Good Enough?

TV innovations

The last few years, we’ve seen continual improvement in the performance of flat-panel TVs and projectors. Where will it stop? What is the Holy Grail in video display anyway?

 

The answer to that question is different for everyone, but the solution is the same. When the display is capable of creating an image that meets all the limitations of the human eye, there’s no reason to keep improving. Everyone’s eyes see the world slightly different, whether it be color, contrast, sharpness, or action. That’s why some people hate 3D and others love it. (But that’s a topic for another discussion.)

 

To compare what a typical person can see versus today’s top displays, we need to look at four areas that affect the imaging in the human brain: color, contrast, spatial resolution, and refresh or frame rate.

 

First, let’s look at color. We’ve recently heard talk about “color space” or “color gamut.” This is defined in fancy three-dimensional charts, but basically it’s the total volume of color the eye can see or a display can create. 

 

When REC 709—the color standard for HDTV—first came out, it could reproduce about 35% of the total colors the human eye can see. P3, or digital-cinema color space, took the amount to about 50%. Most of us—especially those of us who remember NTSC—think this looks incredible, and yet we’re still only at 50%.

TV innovations

the triangle on the right shows the significantly expanded color space for 4K Ultra High Definition

New discussions are about REC 2020, which will take the total color space to 75% of what the eye can see. Some flat panels can do this now, but projectors have a tough time reaching this with conventional lamps and will require pure RGB laser to achieve both the color space and light output needed to really appreciate all those colors.

 

In roughly 10 years, we’ve doubled the color space that can be seen on a consumer display, yet very little content is available to appreciate the full scope of this improvement. There’s still some room for improvement, but the big gains have already been accomplished.

 

Now let’s look at contrast. The human eye is an amazing organ. If you remember from science class, it’s made up of cones and rods, which are microscopic sensors that can detect content and send images to the brain.

 

Rods work at very low light levels (like when you wake up in the middle of the night) and cones need a lot more light and are used to see color. At night, the iris in our eye opens up to let more light in, but the rods don’t detect much color so we pretty much see in black and white. In this condition, we can see a lot of detail in black levels. On a nice sunny day, we get lots of light and color into our eye, and the cones take over. If we compare what the human eye can see in low light levels to what we can see in bright daylight, our range of contrast is huge.

TV innovations

HDR (high dynamic range) comes much closer to approximating human vision than
does SDR (standard dynamic range)

This is the magic of HDR. By applying different values to bright scenes than it does to dark ones, it more closely matches how the human eye responds, providing much more dynamic contrast. HDR has the most overall impact on picture performance than anything we’ve seen since HDTV, and yet few can explain how and why it works. (Not to mention that there are so many watered-down variations.) But let your eye decide, and it will see the impact of HDR every time from anywhere in the room. 

 

In Part 2, I’ll talk about spatial resolution, refresh or frame rate, and why pixel counts aren’t as important as you might think they are.
