8K TV refers to TVs with a resolution of 7680 x 4320 pixels, which is equivalent to 33 million pixels in total. The "K" stands for "kilo" or 1000, so 8K means approximately 8000 pixels horizontally.
8K TVs have 4 times the number of pixels as 4K TVs (3840 x 2160 pixels) and 16 times more pixels than 1080p Full HD TVs (1920 x 1080 pixels). This allows 8K TVs to display images with unprecedented levels of detail and sharpness.
- 1080p Full HD: 1920 x 1080 pixels (2 million pixels)
- 4K UHD: 3840 x 2160 pixels (8 million pixels)
- 8K UHD: 7680 x 4320 pixels (33 million pixels)
The ultra-high resolution of 8K allows even very large screen sizes to retain a lifelike level of detail that is sharper and clearer than lower resolutions. This helps eliminate pixelation and that "screen door" effect you can see on some 4K and 1080p displays.
Is 8K TV Worth It?
Whether 8K TV is worth it depends on your priorities and budget. Since native 8K content is still scarce, the benefits of 8K will mostly come from upscaled 4K or lower resolution video. Many experts argue improved color, brightness, and contrast tech like OLED makes more impact than just resolution alone.
However, as 8K content becomes more available over the next 5-10 years, 8K TVs will provide a significantly improved viewing experience compared to 4K. The enhanced sense of realism and immersion is worth considering for home theater enthusiasts planning to own a TV long-term.
8K TV vs 4K TV
Compared to 4K, 8K TV offers:
- 4x the resolution and pixel density
- More detailed and lifelike images
- Reduced pixelation, even up close on large screens
- Better sharpness when upscaling lower resolution content
- More "future proof" for 8K movies, shows, gaming
However, 4K TVs have the advantages of:
- Wider native content availability now
- Lower costs for both content and TVs
- Maturing and improving display tech like OLED and QLED
So while 4K TVs offer excellent quality for most people, 8K provides an incremental upgrade especially beneficial on very large screens. As 8K prices come down and 8K content expands over the next decade, the advantages will become more compelling for home theater enthusiasts.
8K TV Viewing Distance
To fully appreciate 8K resolution, you need to sit close enough to see the difference from 4K. The ideal viewing distance for 8K is:
- 75" TV: 1.5 – 2.5 ft
- 85" TV: 2 – 3.5 ft
- 98" TV: 3 – 4 ft
Compare that to 4K viewing distance:
- 75" TV: 2.5 – 4 ft
- 85" TV: 3 – 5 ft
- 98" TV: 4 – 6 ft
So you can sit about 50% closer to fully enjoy the enhanced clarity of 8K resolution. This does require some furniture rearrangement for optimal movie watching.
Is the Human Eye Capable of Seeing 8K?
Yes, the human eye is capable of seeing the difference in resolution offered by 8K TVs.
When viewing a 75-85 inch TV from 1.5 to 4 feet away, most people can discern the increased detail in 8K over 4K. Small text is sharper, tiny details in images are clearer, and pixels are not visible.
However, the full benefit is only achieved when watching native 8K content. Upscaled 4K won‘t be quite as dramatically improved. And those with less than 20/20 vision may not fully appreciate 8K.
When Will 8K Become Mainstream?
Most experts predict 8K TVs and content will go mainstream in 5-10 years. Prices are dropping quickly, just like they did when 4K emerged. And movie studios are starting to release films and shows in 8K resolution.
The tipping point where 8K content becomes widely available is likely 3-5 years away. Once major streaming platforms offer extensive 8K libraries, demand will accelerate. This should help make 8K the new standard resolution for TVs.As a home theater enthusiast, you‘re likely always looking for the next big leap in display technology to give your movies, shows and games the most lifelike visual experience possible. The latest display resolution that delivers a giant leap in realism and immersion is 8K. But what exactly does 8K mean and is it worth upgrading your beloved 4K TV?
I‘ll provide an in-depth look at what 8K TV offers, how it compares to 4K, when 8K will go mainstream, and if those extra 33 million pixels actually make a difference to the human eye. Let‘s dive in.
The Ultimate Resolution: What Does 8K Mean?
8K refers to display resolution that is 7680 pixels across by 4320 pixels vertically, for a total of 33,177,600 pixels. The "K" stands for 1000s, so 8K is approximately 8000 pixels wide.
Compare that to 1080p Full HD screens which have 1920 x 1080 pixels. And 4K Ultra HD which quadruples that to 3840 x 2160 pixels and around 8 million pixels total.
So 8K has 4 times more pixels horizontally and vertically than 4K, and 16 times more than 1080p! This allows displays to reveal a level of detail and realism that 1080p and even 4K screens cannot match.
Just imagine looking at a nature 8K video and being able to clearly see each blade of grass or the tiniest pores on someone‘s face. It‘s a big upgrade.
How Many Pixels are in 8K vs 4K vs 1080p?
|1080p Full HD||2 million pixels|
|4K UHD||8 million pixels|
|8K UHD||33 million pixels|
As you can see, the jump from 4K to 8K is much more dramatic than the 4X increase in resolution implies. Those extra pixels add up to a lot more visual information.
8K TV Benefits: Why All Those Extra Pixels Matter
More pixels mean sharper, more detailed, more lifelike images. Here are some of the benefits 8K resolution provides:
- Reveals finer details no other resolution can show
- Eliminates pixelation and screen door effect
- Minimal motion blur during fast action scenes
- Allows larger screen sizes without compromising image quality
- Upscaled 4K and 1080p content looks better
- More immersive experience, especially on big screens
You need very large screen sizes to fully appreciate 8K, which is why early 8K TVs are 85 inches and larger. Sitting just 4-6 feet from an 85"+ 8K display shows details and realism no other resolution matches.
Up close, you won‘t see any pixels or distortion, just stunning clarity even on intricate textures, small text, or faces in a crowd. It‘s a sight to behold.
When Will 8K Go Mainstream?
Just like with 4K, it will take several years for prices to drop and content availability to increase enough for 8K to go mainstream. Most experts predict 8K will surpass 4K as the new standard TV resolution within the next 5-10 years.
We are on a very similar trajectory as the rise of 4K TVs over the past decade. According to the Consumer Technology Association, about 600,000 8K TVs were sold in the US in 2021, a 200% year-over-year increase. That‘s higher than 4K adoption rates were at the same point after introduction.
Samsung, who shipped the first 8K models in late 2018, predicts 20% of their premium TVs sold will be 8K by 2023. We still have work to do on native 8K content but most major studios and streaming platforms are gearing up for the shift to 8K.
So within 3 to 5 years, there should be enough 8K movies and shows available for demand to really take off. No TV purchase lasts forever so upgrading to 8K within the next 2-3 years will help future-proof your home theater.
Ideal 8K TV Viewing Distance
To fully appreciate every added pixel 8K provides compared to 4K, you need to sit close enough to the large screen to notice the increased detail and sharpness.
Here are the ideal viewing distances for 8K TVs:
- 75" 8K TV: 1.5 – 2.5 ft away
- 85" 8K TV: 2 – 3.5 ft away
- 98" 8K TV: 3 – 4 ft away
For a 75" or 85" screen, that‘s about 50% closer than the ideal 4K viewing distance. It may require some furniture rearranging but that proximity showcases 8K‘s strengths.
You‘ll immediately notice small text is razor sharp, you can see every leaf on a tree, tiny blemishes on skin, and nearly invisible pixels in a 4K image. While not practical for every seating scenario, optimal movie night viewing will reveal what your 8K investment provides over 4K.
Can the Human Eye Actually See 8K Resolution?
This is a common question – can we even tell the difference between 4K and 8K with normal human vision? The answer is yes, in most cases the human eye can resolve the increased level of detail 8K displays provide.
When sitting 1.5 to 4 feet from a 75 inch or larger 8K screen, most people with decent 20/20 vision will see the improved clarity and reduced pixelation compared to 4K. The difference is less obvious on smaller screens or from further away.
The "k" terminology doesn‘t directly correlate to visual acuity but 8K resolution exceeds what is discernible to the naked eye. Of course those differences are most apparent on native 8K content. Upscaled 4K won‘t showcase 8K‘s capabilities quite as dramatically but it still improves sharpness and image quality.
8K TV vs 4K TV: Key Differences
Let‘s summarize the key differences between 8K and 4K TVs:
|8K TV Benefits||4K TV Benefits|
|– 4x more resolution vs 4K
– More lifelike, detailed picture
– Eliminates screen door effect
– Upscaled 4K looks better
– More future-proof
– Wider content availability
– Lower cost for TVs & content
– Mature high-end display tech
– Excellent picture quality
As you can see, 8K provides the ultimate in resolution and picture quality but 4K TVs have compelling advantages that make them a better choice for most people currently. No one will complain about owning a high-end 4K OLED or QLED TV.
But for home theater buffs who want the best and plan to own their new TV for 5-10 years, 8K is worth the upgrade.
What Display Tech Works Best for 8K TVs?
To take full advantage of 8K resolution, you need premium display technology with exceptional contrast, brightness, HDR and color. Early 8K LCD/LED TVs struggled but OLED and QLED are up to the challenge.
Both LG and Samsung now offer 8K models in their OLED and QLED lineups. The self-lit pixels in OLED provide essentially infinite contrast while QLED has higher peak brightness. Either option brings out the best in native and upscaled 8K video.
Some other display technologies like MicroLED promise even better image quality than OLED down the road. But OLED and QLED will be the elite display options for unlocking 8K‘s full potential in the near future.
Native 8K Content: Movies, TV Shows, Sports and Gaming
A new display resolution requires filmed and processed native content to realize its full benefits. While nowhere near as abundant as 4K, the amount of native 8K movies, shows and gaming content is increasing steadily.
On the movie side, studios like Warner Bros have released major films like Wonder Woman and Aquaman in 8K. Netflix and YouTube offer some 8K demo footage but need more native content. Olympics and World Cup coverage is being filmed in 8K.
Gaming is making the shift with support from consoles like the PS5 and graphics cards. Expect native 8K games to become commonplace within 5 years.
It will take a bigger library across streaming services and discs for native 8K viewing to go mainstream. But the expanded resolution is coming, following the same path 4K did.
Should You Buy an 8K TV in 2023 and Beyond?
If you‘re an avid home theater fan planning to own your next TV 5+ years, want the best big-screen picture possible, and don‘t mind paying a premium – yes, buying an 8K TV makes sense.
Prices on 8K models from Samsung, Sony, LG and others have dropped below $3000 for 85" screens and will continue falling. Even without abundant native 8K content yet, these TVs will provide a great viewing experience and incrementally better upscaling.
If your budget is more modest, a high-end 4K TV likely makes more sense for now. Improved display tech like OLED often makes more of a difference than resolution alone. But 8K is the new benchmark for resolution and will be the standard for premium TVs in the near future.
The Bottom Line
8K TVs with four times more pixels than 4K provide unparalleled levels of detail and realism. While native 8K content is still growing, these TVs showcase noticeably improved sharpness and clarity compared to 4K.
Within the next 5 years, 8K will become the new high-end TV standard as prices drop and 8K movies, shows, sports and gaming really take off.
If you want the absolute best TV picture quality and plan on keeping your new set at least 5 years, upgrading to 8K is recommended. It future-proofs your investment while providing the most lifelike experience available.
I hope this detailed overview helps explain what 8K TV is all about. Let me know if you have any other questions!
