What is 8K TV? Everything You Need to Know About 8K TV

 

8k TV

8k TV is a new type of television that has been developed by the  Samsung company. 8K TV has four times more pixels than 4K images, measuring 7680×4320 pixels which are 33,177,600 pixels in total. 8K delivers 16 times the resolution of HD, transforming flat images into a deeper, more lifelike experience. Samsung was the first to bring 8K to the market and continue to give you the best TV experience.

8K Direct Full Array technology illustrates the image in the most precise way, with LEDs directly behind the image that are points of light that individually turns on and off. Such detailed control increases contrast eliminates blooming and truly makes light scenes pop. All providing you the most accurate picture.

The 8K Quantum Processor is the first processor to hit the market and the only one that enables remixing today’s content into incredible 8K quality. It also optimizes sound for each sequence, controls brightness to the scenery of the room. That all makes it the most powerful processor ever.

What is 8K?

8 K resolution refers to image resolution or monitors size with a maximum of about 8000 pixels.  8K TV is said to produce images that cause stronger sensory experiences with such accurate colors. Once presented at a standard distance from the device, high-resolution displays such as 8K enable each pixel to be invisible to the human eye. 8K resolution can also be used to create improved images of lower resolution using a combination of cropping techniques used in picture and film editing.

Resolutions such as 8K enable viewers to film with a wide lens in high resolution, in the case of potentially dangerous subjects, by being able to digitally zoom in and crop in post-production. The technique involves taking a part of the initial 8K image and cropping it to suit a lower size, such as the current high-definition television industry-standard (4K, 1080p, and 720p).

It is labeled 8K because the videos are about 8,000 pixels long, give or take a few hundred pixels, but the standard still falls under the Ultra HD umbrella term, so some people use the term Ultra HD 8K.

4k vs 8k which is better:

Simply-set, the resolution is the number of pixels used to make up the TV display. Higher-resolution screens make it easier for your favorite games, videos, and TV shows to reveal the fine detail. It might seem like a no-brainer to switch to a higher resolution TV, but it’s not always appropriate.

TV Sizes Available 55″ to 100″+ 40″ to 100″+
Height in pixels 4320 2160
Width in pixels 7680 3840
Availability Okay Excellent
Content Availability Extremely limited Excellent

 

8k TVs are an impressive step up in television capabilities. Such new screens provide impressive levels of detail, providing 4x the number of pixels on a 4k TV and 16x the number of pixels on a 1080p TV. Unfortunately, as great as these TVs are, they have almost no content available. This will likely change in the coming years as more 8k content is available, but it will likely be at least 3-5 years for 8k movies, so for now, it probably isn’t worth getting an 8k TV.

Content:

There is almost no 8k content currently available. There are some demo clips currently available on YouTube, as well as several tech presentation videos free for download. On the only 8k TV we’ve reviewed so far is the Samsung Q900R. The 8k videos available on YouTube are limited to 4k streaming because the TV actually doesn’t accept the 8k file format of YouTube.

Some current PCs can output at 8k, but they are limited to a maximum refresh rate of 30Hz and there are a few other limitations. This is due to the limits of HDMI 2.0 in bandwidth, and this situation will change dramatically once the first HDMI 2.1 graphics cards are released.

PC Games Yes Yes

 

One of the main reasons that hardly any content is available is because the vast majority of video production is still shot in 4k or less. A few recent films, including Disney / Marvel’s Captain Marvel and Guardians of the Galaxy Vol, were at least partially shot in 8k. but even these were only partly shot in 8k, so they perfected the final movies in 4k. 8k movies are likely at least 3-5 years away.

Why do you need an 8K TV?

The real justification for 8K is on the rise in size demand. People buy bigger TVs and are pleased to have bigger televisions in their houses. Where you might have had a 28-inch TV 15 years ago, now 55-inch is common. 65-inch and above is where the majority of TV sales growth is expected in the next 5 years.

Now you can get big 4K HDR TVs-up to around 85 inches. Additional pixels allows further noticeable information as the image gets bigger-and you keep seated in the same position. The 2019 models reaching out to 98 inches tells you where 8 K’s going. You’ll typically get Full HD up to 40 inches, 4K up to 60 inches and then 8K over that in the future, and 8K only really refers to that bigger sizes-if the TV is too small, the pixels will be too tightly packed for you to see the difference in the picture.

As detail increases, you can sit and marvel in front of a huge image that feels like it’s engulfing you. It’s here that big 8K TVs have a natural advantage because it increases the angles that light comes into your eyes. This can, in effect, enhance the contrast between the focus and the backdrop, build more of visual pop and give you more immersive viewing experience. You can’t sit too close, of course, because you will need to continuously move your head to see the full image, so limited viewing distances also apply.

Is an 8K TV upgrade worth it?

This is very much down to who you are and what your tv requires. Let’s differentiate the point from the total resolution: for a company like Samsung, the Q900/Q950 is their flagship TV. It’s designed for the best performance, no matter what stuff you’re feeding into it. It is also the 8K TV of the business and is great for upscaling results. And purchasing a top-level 8K TV has some advantages, not just buying resolution.

At the same time, for many users, a lack of 8K content from a suitable source might present something of an obstacle to adoption. This, we’re positive, would crash in over the next 3-5 years, when we expect 8K to be much more popular. With that in mind and, a television set’s average life being about 5 years at least there’s probably a lot of development to come before you’ll be watching 8K content natively with having the most out of an 8K tv.

With that in mind, it’s difficult to recommend  8 K television that we might see emerging over the next 12-18 months. If you don’t buy quality, then you probably won’t have a great 8K experience.

Samsung Q900/Q900R 8k QLED TV Review

Check the Price on Amazon

The Samsung Q900R is an outstanding 8k LED television with incredible quality pictures. It can be very luminous in both SDR and HDR. Although it has a VA screen, due to the’ Ultra Viewing Angle ‘ layer it has large viewing angles that hold an accurate image when viewed from the side at the advantage of lower contrast. Despite the low native contrast ratio, the very good local dimming helps greatly enhances dark-room efficiency. It has great performance in HDR and very good handling of the reflection. The Q900 has outstanding control of the motion and very low latency in performance. Finally, like all premium Samsungs since 2018, the Q900R has support for the FreeSync variable refresh rate.

It has excellent picture quality with good performance in the darkroom, which also stays accurate when seen from the edge. It has remarkable handling of the motion with very little blur and fast-moving content, like sports, is crisp. The input lag is very low and the TV automatically reacts to your movements which are perfect for players and those who use it as a PC monitor.

The Samsung Q900 is a high-end television set. It is the first 8k TV on the market and currently stands just above Samsung’s 4k model, the Samsung Q90R. Samsung Q900’s main 8k rivals are expected to be the Sony Z9 G and the LG SM9975. The Q900 signals the start of a modern 8k TV era.

PROS

  • 8k resolution.
  • Wide viewing angles, great for a VA panel.
  • Great local dimming and dark room performance.

CONS

  • A lot of dirty screen effect is evident on the screen.

Design:

The Samsung Q900 is excellent in design. It’s made mostly of metal and it has a very durable stand that supports it well. It is very lightweight and can be installed on a wall using a regular VESA wall mount, or a separately marketed wall mount to flush it with the ground. The TV and the included One Connect device get pretty warm but this shouldn’t be a concern. The Q900R stand is very strong, holds the tv very well, and makes almost no vibrate.

The back of the screen is plain. When you want to wall mount it, the large space that appears like an “M” is used to hold the wings. Samsung offers a different no-gap wall mount separately, which keeps the TV flat with the ground. The Q900RB uses a One Connect system that transfers all necessary signals (including power) through a single cable to the TV. The back of the TV has grooves that serve as cable management and guide the One Connect cable either through the legs or at the center of the TV, as you can see here.

Samsung Q900 build quality is outstanding. It’s very similar to the Q9FN or Q9F, but there is some flex to the spot where the back panel crosses the side bezels and they aren’t connected one by one. You shouldn’t have any issues with TV though.

Picture quality:

The Samsung Q900R’s native contrast ratio is only average but this is offset by the great local dimming of the TV. The native contrast level is far superior to most VA screen TVs. This is due to the ‘ Ultra Viewing Angle ‘ layer in television that increases viewing angles at the cost of contrast ratio. This is very similar to what we have seen with the Sony Z9F device and the X-Wide Angle.

Unfortunately, local dimming of the TV can not be fully deactivated using the usual configuration menu. We had to disable PC Mode Dimming in the service menu of the TV to measure the native contrast ratio, and then activate both PC Mode and Game Mode at the same time.

Motion:

The Samsung Q900 has an incredibly fast response time. Fast-moving objects will have only a slight blur stream, and the only change with substantial overshoot is the phase between 0-20 percent, which correlates to very dark shades.

The Q900R dims with PWM to dim the backlight. Flicker is always present and at lower brightness and becomes more extreme. The flicker frequency, however, is 960Hz so you probably won’t see it anyway.

Conclusion:

It has excellent picture quality with good performance in the darkroom, which also stays accurate when seen from the edge. It has remarkable handling of the motion with very little blur and fast-moving content, like sports, is crisp. The input lag is very low and the TV automatically reacts to your movements which are perfect for players and those who use it as a PC monitor.
