It’s the most near-perfect technology ever for watching TV, but there is almost no reason for the average consumer to invest in it. It’s called 8K, and it offers double the resolution of the current high-end, known as 4K, which itself offers twice the resolution of regular high-definition TV.
It sounds incredible, and it is. One has to step right up to an 8K screen, with ones nose almost to the glass, before one can see the tiny grid that makes up the display pattern. Where HD has 1920 horizontal lines down the TV screen, 4K has 3840, and 8K 7680 lines. When multiplied by vertical lines – HD at 1080, 4k at 2160 and 8K at 4320 – one sees an exponential increase in the number of pixels. These light elements that make up the picture leap from 2-million in HD to 33-million in 8K.
There is one fundamental problem with this dramatic leap in display technology: the world of content has yet to catch up with it. So, unless one has money to burn and an appetite for showing off, there is little point in buying an 8K set – for now.
What it really represents is the TV manufacturing industry demonstrating both its readiness for the content revolution, and its ability to lead in technology. This means that, because a Samsung or LG unveils an 8K unit, consumers will have their perception of that company’s technology leadership reinforced, and feel more compelled to buy one of their lower-end TVs.
The further reality is that the new cutting edge technology that gets announced today is the mainstream technology three years from now and the entry-level in five to ten years. When the first OLED display was unveiled by Sony at the Consumer Electronics Show in Las Vegas a decade ago, a tablet-sized screen would have cost $20 000, or nearly R300 000 in today’s money. Yet, the same technology is now available in large-screen TVs for less than R10,000. A few years on, Samsung and LG unveiled the next big thing, Quantum Dot TV screens, at well over R50,000. Now Samsung’s version, called QLED, and HiSense, with ULED, are available for under R10 000.
In other words, the price of the cutting edge keeps coming down, and each new cutting edge drops in price faster than the one before.
So, when Samsung announced recently that it’s new QLED 4K and 8K TV models will be available at select retailers in South Africa from this month, it wasn’t mere hype.
Samsung argued that the 2019 editions of the Q80 and Q90 feature “Ultra Viewing Angle technology, which restructures the TV’s panels so the backlight passes through the panel with lights evenly onto the screen”.
The Q70, Q80, and Q90 models offer “Direct Full Array technology that uses a panel featuring concentrated zones of precision-controlled LEDs”. These adjust automatically to display deeper blacks and purer whites, delivering dramatically improved contrast.
Users of the Q900 model series won’t have to wait for content to be made in 8K format either. It uses the company’s Quantum Processor 8K to “up-scale” lower resolution content to 8K and optimises audio and video to the specific content on the screen.
In the same way, the QLED 4K models feature Quantum Processor 4K, which up-scales HD to improve brightness, picture quality and sound, based on each individual scene.
Meanwhile, at a Global Press Conference in Andalusia, Spain, last month, the organisers of the annual IFA tech fest in Berlin gave the media a sneak preview of what to expect at the event in September. Top of the list was 8K TV.
Hisense and Skyworth both signalled their intentions to join the 8K TV technology race, but at a far more affordable level than the industry leaders.
Hisense showcased the 74U9E 8K TV, a 75-inch monster that is due to be launched in China this year, and is likely to come to South Africa early next year.
It offers improved contrast and more vivid colours over the previous Hisense U range TV, while sound is integrated, with a subwoofer embedded into the stand of the TV. Like the Samsung 8K machines, the display dynamically upscales 4K content in real time.
At the IFA press conference, Skyworth showcased its 8K TVs via German TV brand Metz, which it acquired last year. The company offers a “premium-affordable” sub-brand called Metz Blue and, startlingly, this low-cost brand was chosen to showcase 8K TV, meaning it will reach the mass market even more quickly than previous high-end technologies.
With Skyworth having brought the first Android-based TV to South Africa last year, it came as no surprise that its new S9A 8K OLED is an Android TV, combining vivid picture colour with Android TV functionality. As Gadget’s Bryan Turner, who attended the event, put it: “Witnessing the 8K and OLED combination was incredible and felt like getting a new set of glasses.”
It supports the latest streaming apps, and can be controlled via the voice-controlled Google Assistant, which is available on most Android phones.
In short, 8K is on a fast-track to our living rooms, at a speed never seen before in cutting edge TV.

Did an earthquake take out SA Internet?
Seabed avalanches caused by an earthquake could have cut several undersea cables, leading to one of South Africa’s biggest Internet outages yet, writes ARTHUR GOLDSTUCK.
There is still no official explanation for freak breaks 11 days ago in two separate undersea cables that provide international access to South Africa’s Internet users. However, as reported in the Sunday Times yesterday, the most common causes of such breaks are damage by ship anchors and earthquakes at sea.
However, the freak occurrence of two separate cables being cut simultaneously far out at sea, as happened on the morning of 16 January, can only be explained by sea-bed activity. One of the cables was cut in two places, and it is widely believed that a third major cable was also cut.
The cable damage mostly occurred in or near an area called the Congo Canyon, which starts inland and extends 220km into the sea. It is known for having the world’s strongest “turbidity currents”, underwater sediment avalanches over hundreds of kilometers, which are known to destroy undersea cables.
The most likely culprit is a 5.6 magnitude earthquake that struck the Atlantic Ocean near Ascension Island shortly before the cables were cut on the morning of 16 January. The earthquake occurred just before 8am South African time, and local ISPs reported losing international access from just before 10am. The epicentre of the earthquake was more than a thousand kilometres off the coast of Africa, but disturbances caused by seismic activity at sea become more powerful as they approach the coast. Combined with turbidity currents, this could well have taken out all cables in the area.
The West Africa Cable System (WACS) was cut in two places, and the South Atlantic 3 (SAT3) cable in one location. Industry insiders believe that the Africa Coast to Europe (ACE) cable was also cut, but it has not been publicly confirmed.
South Africa is connected to the global Internet via seven such cables, with a total capacity of 42.3 terabits per second (tbps). These cables, in turn, connect to additional cables connecting the West and East coasts of Africa, with a single cable running from Angola to Brazil providing another 40 tbps.
However, it emerged in the past week that smaller ISPs in South Africa had bought capacity on only one or two cables. In a freak occurrence, two of the most commonly used cables, the WACS and SAT 3 cables, were cut simultaneously, plunging millions of Internet users into data darkness.
Customers of the major mobile network operators – Vodacom and MTN – were largely unaffected, as these tend to have both part-ownership and access to most of the cables running up both the East and West coasts of Africa.

Lenovo express-delivers new range from CES to SA
Lenovo has unveiled its new range of ThinkBook laptops, barely two weeks after they were showcased at the Consumer Electronics Show in Las Vegas.
The company’s newest sub-brand, ThinkBook, is intended to meet the demand for more aesthetically pleasing, yet agile and powerful devices.
The new range is aimed at small and medium enterprises. According to the Small Enterprise Development Agency (SEDA), there are more than 2-million SMEs in South Africa – although there are only 667,433 in the formal sector. This tallies with estimates in recent editions of SME Survey, produced by World Wide Worx, which suggest 650,000 active, formal businesses in South Africa. These SMEs employ about 14% of the South African workforce.
Lenovo argues that access to affordable, yet efficient, technology is a crucial factor in aiding business success and contributing towards the success of the nation. The company has found, in its own research, that younger people prefer working, creating and communicating online “with stylish devices that make a statement”. This means they require streamlined laptops which can be used to collaborate from any remote location, to enhance productivity.
Lenovo said in a statement on Thursday night: “Backed by customer research, ThinkBook is specially designed for SMEs, who typically purchase consumer laptops for perceived design and price advantages but can no longer rationalise their lack of extended services and warranties – core needs of any business. ThinkBook allows growing firms to keep a competitive edge in attracting today’s young tech-savvy execs with trendy yet cost-effective devices.
Thibault Dousson, general manager of Lenovo for Europe, Middle East and Africa, said at the launch event: “With the capacity, SMEs have to grow and upskill the country’s workforce, they are perfectly positioned to bridge the gap between the public sector and large enterprise. Bearing in mind the demands of the digital economy, this sector needs skills and resources in order to compete, and that is where devices such as the ThinkBook come in.”
In South Africa, ThinkBook laptops are now available in 13-, 14- and 15-inch variants. The flagship ThinkBook 14 and ThinkBook 15 devices are powered by Windows 10 Pro and up to 10th Gen Intel Core processing, which Lenovo says combines high performance with intuitive, time-saving features. Options include Intel Optane memory, WiFi 6, and discrete graphics.
The ThinkBook 15 comes at just 18.9mm thin, while the ThinkBook 14 is a mere 17.9mm, both with FHD displays and two Dolby Audio speakers, dual-array, Skype certified microphones and a USB 3.1 (Gen2, Type-C) port.
Lenovo has also introduced the ThinkBook S series, including an elegant 13.3-inch ThinkBook 13s. The sleek and light device is constructed of a metallic finish on an all-aluminium chassis, alongside a narrow bezel display. As with the ThinkBook 14 and 15, the ThinkBook 13s also features advanced Intel processing and an FHD display, Dolby Vision and Harman speakers with Dolby Audio.
