Why is 4K upscaling so bad?

Sony Bravia Smart TV X950G

Episode 1643

Greg from Apple Valley, CA

Greg was looking to upgrade to a new 4K TV, and got a Sony Bravia, and found the upscaling was terrible when watching live TV. A year later, the TV has gone out and he has to replace it. Will he have an issue with another 4K TV? Or should he just try and get and older 1080p TV. Rich is not a fan of upscaling, and the native resolution will always be better because upscaling can't invent resolution that's got clarity. Just watch it the way it is, unless it's a 4K native signal. Netflix and Amazon Prime, for instance, stream in 4K. But TV channels vary from 720-1080i-1080p. 

Scott Wilkinson ... 1 1/2 Times the Screen Height

Scott Wilkinson

Episode 1628

Scott saw some content on a Samsung 8K TV last week, and he sat about one screen height away from the image (it's best at 1 1/2 times). It was so good he could barely see the pixels. Very sharp. The problem is, there is no real native 8K content, and probably won't be for a while. And Scott says that while the resolution was impressive, he couldn't see much of a difference between it and uncompressed 4K UHD blu-ray. But Scott says that the upscaling is where 8K really is at right now.

Is Samsung as good as Panasonic with 4K TVs?

Jason from Fontana, CA

Jason bought a Panasonic Viera 4K TV two years ago. What he wants to know if he buys a newer Samsung 4K TV, will it be as good? Leo says in fact, it'll be better. Todays' 4K TVs have HDR, which is great for color and dynamic range. Leo says they're all pretty good now and you can't even notice upscaling on lower resolution content. So buy all means, pick up a Samsung.

Why are people buying 4K TVs if there's not much content available for it?

Vizio P-Series Ultra HD TV

Episode 1328

Alan from Laguna Nigel, CA

Alan's wondering why people are buying 4K TVs when there isn't a lot of content available in 4K yet. Scott says it's because manufacturers are all making 4K TVs, and aren't even really making 1080p TVs anymore. While he's right about there not being a lot of native 4K content yet, it is growing and there is some. When you don't have 4K content, the TV will upscale it, and then the question becomes what TV has the best upscalers. So when reading reviews, look for how the reviewers evaluate the upscalers.

How much upscaling does a 4K TV do to a DVD?

Glen from Louisiana

Glen wants to know how much resolution a DVD really has compared to a Blu-ray. Scott says DVDs are standard definition which is 720x480. Blu-ray can be 1920x1080 and above. How will it upscale? Scott says the newer his tv, the more it will upscale. If he buys a 4K TV, it will be about 10 times the resolution. The more upscaling it does, the more problems can happen. Scott says he may consider streaming from PBS. It may be in HD, rather than SD.

How important is upscaling in HDTVs?

Episode 1267

Jerry from Cameron Park, CA

Jerry's elderly mother has UVerse cable, and she can't afford the HD service. Currently she has an old Sharp 720p TV, and Jerry wanted to replace that for her. Should he buy a 720p TV or a newer 1080p? He was told that the newer, smaller 1080p TV sets don't upscale. Leo says it's a big deal if an HDTV doesn't upscale, because standard definition will look a lot worse. The set top box may upscale, though. Better cables may also help. It also would help to use HDMI instead of composite if it's a possibility.
