Mark Nota writes: I’m at present watching the 1980 film Superman II on my Hisense U7G with a Vizio M collection soundbar by means of my Roku Ultra. It says it’s in Dolby Vision and Atmos. Can a Nineteen Eighties film be in Dolby Vision and Atmos?

Yes, Mark, it could actually. Older movies can have their video and audio remastered and be introduced in Dolby Vision and Dolby Atmos. However, simply because a remastering course of is finished doesn’t imply it’s essentially good — or that it’s as efficient as newer content material that’s been remastered.

From what I perceive, movie negatives enable for a median of about 13 stops of dynamic vary. (That is, from the darkest components to the brightest.) SDR TV permits for about six stops of dynamic vary on common, and the movie prints that had been performed in theaters had comparable limitations.

Today, HDR permits for about triple the dynamic vary of SDR. So, there’s loads of alternative to take the unique movie and create a brand new, excessive dynamic vary grasp from it. And in case you selected to make use of Dolby Vision to ship that HDR, then you can be fairly meticulous about how the ultimate HDR grasp of that movie appeared.

Of course, one may additionally telephone it in and make one thing that’s solely marginally higher than the unique presentation. It actually relies on the standard of the work, which normally relies on funds. But, yeah, the unique movie negatives had been extra able to holding the next dynamic vary than both the theater print or the video copy had been in a position to present us. Now that now we have HDR TVs and HDR supply mechanisms, we are able to remaster outdated content material captured on movie and current it in HDR.

It’s an identical, but barely extra sophisticated story for Dolby Atmos. You technically can create a Dolby Atmos monitor out of nearly any unique audio supply. But how good that Dolby Atmos expertise will likely be relies upon some on the supply materials, and a few on the funds for the manufacturing. The extra audio tracks one has to work with, the extra inventive freedom is enabled. But on this day of computer-based audio processing, some fairly unbelievable stuff may be created utilizing restricted unique audio sources. So, once more, not all Dolby Atmos is equally spectacular and even good. But if somebody takes the time to do it, a Dolby Atmos audio monitor may be created and delivered for an older movie.


Will TV producers give attention to bettering onboard audio?

Zach Harris writes: Do you suppose that there’ll come some extent sooner or later the place TV manufactures begin focusing extra on their audio for his or her TV lineups? It stands to cause that sooner or later TV image high quality will hit diminishing returns and there received’t be way more to entice clients to improve. Focusing on premium, enhanced audio methods is likely to be one treatment to assist entice folks to buy new units, particularly when many individuals simply find yourself utilizing their TV audio system anyway.

You know, I don’t know if there’s anybody on the market who loves getting out the outdated crystal ball and peering into the long run greater than I. Here are my ideas on this.

First, I believe we’re additional away from reaching such show nirvana that there’s little room left for enchancment. I believe the following 10 years at the very least are going to see extra thrilling enhancements in image high quality. We’ve obtained ongoing work on show know-how like electro-luminescent quantum dots (or so-called QDEL shows, which we spotted at CES 2024) and Phosphorescent OLED (or PHOLED), each of which may signify some substantial enhancements in image high quality. I believe processing is simply going to get higher as AI and computing energy advances. And as bandwidth limitations begin lifting, there’s a possibility for sooner or later getting uncompressed video supply, and that will likely be a sport changer.

All of that’s to say: I don’t see the premise that image high quality hits such a wall that every one that’s left to entice people to purchase a brand new TV is enhancements in audio high quality.

Also, the TV enterprise will proceed to thrive by nature of the truth that tech simply ultimately dies. Far extra people purchase new TVs as a result of their outdated TV breaks. The variety of TVs bought to true “upgraders” pales compared from what I’m informed.

But I believe the true impediments to improved sound high quality in TVs are a mix of the legal guidelines of physics and shopper preferences.

Here’s what I imply by that. Despite all of the advances which were made in digital sign processing, digital amplification, and transducer supplies (that’s the stuff that audio system are made out of), it hasn’t been sufficient to beat the truth that sound is simply shifting air, and shifting air sounds finest when it’s geared toward our ears. Also, to sound their finest, audio system want bodily area.

Consumers have voted in opposition to elaborate onboard TV audio methods time and again. Remember when Sony bookended a few of its TVs with flat-panel audio system? This design was … not warmly acquired, which is why Sony stop doing it. Likewise, super-bulky TVs don’t appear to promote in addition to skinny and lightweight TVs. The backside line is that the overwhelming majority of customers are simply positive with “good enough” in the case of sound. And if they need wonderful sound, they’re keen to leap by means of some hoops and make some sacrifices to get it.


What ought to I do with my outdated TV?

Well, whether it is an older CRT TV, I’d look into promoting it. You’d be shocked how a lot cash outdated CRT TVs are going for as of late, principally due to a rabid retro gaming fan base.

If it’s an older LCD TV? Well, once more, you can strive promoting it for a couple of bucks. You by no means know who is likely to be keen to take it off your fingers and put it of their storage or toss it of their RV. You may additionally strive giving it away whether it is first rate sufficient to make use of, however you’ll be able to’t get any cash out of it. Sometimes underfunded colleges and different establishments could make good use of an older TV that also has some life in it.

Or if no person appears to need it, you’ll be able to rent somebody to select it up and recycle it, or you’ll be able to haul it all the way down to your native waste administration or recycling firm and get rid of it there. Anything that forestalls it from going right into a landfill.


LG OLED vs. Hisense U8N?

Kim Strom writes in, saying that they’re able to improve from their Hisense U9G and are contemplating an improve to a Hisense U8N, however they’re additionally enticed by OLED and are contemplating the LG G4 or G3. They watch a variety of sports activities — hockey particularly — and are additionally all in favour of upgrading in measurement, from 65 inches to both 77 or 85.

The very first thing that jumps out to me right here is that you’re upgrading to a 77- or 85-inch TV. And with OLED, the larger you go, the extra it’s a must to pay. The improve charge for bigger OLEDs is significantly greater than the improve to bigger LCD-based TVs.

If price had been no object, I’d say get the largest LG G3 or G4 you’ll be able to. But price is — and must be — a consideration for most people.

I’d say when you have your coronary heart set on OLED, contemplate getting a 77- or 83-inch LG C3 or C4 OLED. That will get you the OLED image high quality in a bigger display and assist preserve the associated fee down. Also, the processing within the C3 and C4 is fairly excellent and that higher processing will assist preserve your broadcast TV sign wanting nearly as good as it could actually at these bigger display sizes.

For bang in your buck, although, there’s simply no denying the Hisense U8N provides you with some wonderful image high quality — it’s an enormous improve out of your U9G, for certain. And you’ll be capable to get to that 85-inch display measurement with out taking out a second mortgage on the home. It can even be brighter than the OLEDs in case you want that and also you don’t must be involved about sporting the OLEDs down in case you watch hours and hours of hockey each day.


How do I arrange my LG TV with Apple TV and a Blu-ray participant?

Joseph Green writes: Help! I’m in image mode jail. I’ve an LG QNED 85, an Apple TV, and, a Panasonic Disc participant. I wish to alter the image mode settings in order that I can get the very best, most correct image. The drawback is all of them have their very own separate image settings. The Apple TV has Dolby Vision. The LG has all types of image modes, and so does the Panasonic. Do they mix if you use them, or does one override the opposite relying on what you employ? How do I set it and overlook it?

The neatest thing you are able to do with the Apple TV, for my part, is to not let the Apple TV power Dolby Vision in your TV. Some folks just like the look, however not everyone seems to be a fan of the way it makes non-Dolby Vision native content material look. I flip that off, after which I set the Apple TV to match the body price and dynamic vary of the content material supply.

I wouldn’t use any of the “picture modes” in your Panasonic, until you discover they appear higher than utilizing your LG’s image modes alone.

And this brings up message for everybody to listen to: Your TV goes to use processing to the sign your supply sends, be it an Apple TV, disc participant, Nvidia Shield, or no matter — whether or not that sign has had processing utilized already or not. It doesn’t know the distinction. Sometimes, when you have a TV that isn’t all that superior, letting your supply system do some processing would possibly assist. But as a rule, the image processor in your TV goes to be considerably higher than no matter is in that supply system. And since most TVs can’t undo processing that’s already been carried out, meaning it is going to apply processing to processing, and that doesn’t all the time make for the very best outcome.

And in your LG: If you really need essentially the most correct image, then FilmMaker Mode is the way in which to go.
