Buyers of an Ultra-High Definition (UHD) TV should be certain they are purchasing a genuine 4K set in order to guarantee the best entertainment experience.
This is the advice of Samsung South Africa, which is cautioning consumers against some of the so-called branded televisions on the market that are not true UHD. According to the International Committee for Display Metrology (ICDM), Measurement Specifications are likely to be revised so as to prevent low resolution TVs from being sold as 4K UHD TVs to unsuspecting consumers.
“Customers should always check the exact resolution of any television that claims to be UHD quality,” says Matthew Thackrah, Deputy Managing Director and Head of Consumer Electronics at Samsung Electronics SA. “A true 4K TV will have 3 840 x 2160 pixels with exceptional screen quality, whereas a fake one will only offer 3K resolution at 25% less (2 880 x 2 160). The latter also use the RGBW method – which stands for Red, Green, Black and White – that replaces some of the RGB (Red, Green and Black) sub-pixels with white sub-pixels to cut back on production costs. It also, unfortunately, cuts back on the quality.”
Thackrah says the original Measurement Specifications as outlined by the ICDM are being purposefully misinterpreted by manufacturers selling RGBW panels as UHD TVs. The colour is compromised and users therefore do not fully experience true UHD resolution. Many consumers have been caught out by the fake UHD TV moniker, not realising how the combination of RGBW technology and low 3K resolution will impact their viewing.
“It is essential to examine the credentials of any manufacturer claiming to sell a UHD TV and to make sure that resolution is true 4K,” says Thackrah. “Check that the TV has an aspect ratio of at least 16:9, a colour bit depth of 8 bits and a high frame rate of around 24p to 60p. Many units don’t have clear information about the display or the core technology, so ask the right questions and make sure you get the right answers before you make a purchase.”
Samsung has invested considerable research and development into its UHD TV range, including the premium SUHD TVs that have incredible depth, colour and captivating visual quality. Generally, fake UHD TVs do not come with as much feature variety as the genuine article and rarely give consumers the connected lifestyle and dynamic experience that come standard with the real thing.
Thackrah advises consumers that, before spending money on a new UHD TV, they need to check the specifications and be sure that it is a worthwhile investment and not a cheap fake. He says the fact that the ICDM is considering amending the Measurement Specifications going forward should provide customers with an additional layer of protection in the future.
“The picture quality of a fake UHD TV is nowhere near the deep blacks and vivid colours of true 4K,” concludes Thackrah. “It probably won’t turn on with your mobile device, tell you the weather and the time, provide a variety of connectivity options and allow for complete user control from anywhere in the home. A Samsung SUHD TV is something you can truly be proud to have in your home and we urge people not to compromise on quality.”
Spotting the difference between real and pseudo 4K / UHD TVs
- Take a close-up photo of a white portion of your TV screen
- Zoom in the photo as far as it will go:
- If you see perfect vertical and horizontal lines of red, green and blue, repeated in this order throughout, your TV is a genuine 4K UHD TV.
- However, if you see any lines of white mixed in with the red, green and blue lines, your TV delivers pseudo UHD TV.
Prepare for Digital TV migration
The deadline for the digital migration is fast approaching. JACQUES BENTLEY, Skyworth Southern Africa Sales Manager, lets us know what we can expect.
By now you’ve probably heard about the impending digital migration for South African broadcasting. Initially, this shift from old-school, analogue technology to newer, more efficient digital technology was set to take place in 2015 but the deadline for a national migration has been pushed out several times. With our neighbours Namibia and Botswana blazing ahead with their own digital transformations, the pressure is on for our own government to push forward to a fully digital South Africa.
But what does this overdue switch really mean for you and me?
What is digital migration?
Basically, the process involves moving over from an analogue transmission to a Digital Terrestrial Television/Transmission (DTT). We currently use analogue technology, transmitting video and audio through analogue signals. The drawback of this traditional broadcasting format is that the colours, sound and brightness are heavily impacted by the quality of the signal, resulting in a less-than-ideal snowy effect, and your TV deciding to randomly fade or ghost.
Digital TV, on the other hand, boasts crystal-clear image quality and excellent sound without interference because of its land-based network of TV transmitters that broadcast digital signals. This kind of technology also allows viewers to access a wider range of channels with different programmes.
Why is it happening?
Apart from the fact that everyone wants clearer sound, more channels and an enhanced viewing experience, the conversion to digital TV also has a far-reaching goal that ultimately
aids developing nations like our own. According to the International Telecommunications Union (ITU), the objective of Broadcast Digital Transition (BDT) work is to help developing countries with their smooth journey from analogue to digital broadcasting, including terrestrial TV, mobile TV and sound broadcasting. In turn, this means that we can enjoy new broadcasting services as well as an allocation of the digital dividend.
When is it taking place?
June 2019 is D-Day for all countries to have completed their digital migration. Our Communications department is determined to meet this international deadline and has implemented a specific DTT war room to ensure that all the boxes are ticked, and they can deliver on time.
The first province to undergo the digital migration was the Free State back in August, where digital Set-Top Boxes (STBs) were launched in Senekal. Essentially, STBs decode digital signals for old, box-style TV sets and the government aims to distribute these devices to about 5-million poor households, so that all citizens can enjoy prime TV, despite their financial situation. In fact, Skyworth is one of the chosen suppliers of these set-top boxes and is proud to be a core part of an all-inclusive transition to digital.
What can you do about it?
While the government has agreed to subsidise cash-strapped consumers with STBs, the only guarantee is that the digital migration is upon us and it is our responsibility to digitally transform our homes in order to meet the requirements. This means that you’ll either need to invest in a digital-ready TV or purchase your own STB to work with your current TV’s analogue signal. Whichever route you decide to go, you can look forward to exceptional viewing entertainment in the comfort of your own home.
5 things you should ask about buying a new TV
With so many technological advancements that cater to various needs, and endless options on the market, buying a new TV for your home can be pretty daunting. JACQUES BENTLEY, Southern African Sales Manager at Skyworth, offers a few tips when buying a new TV.
Given the role a TV occupies in the home – providing entertainment, relaxation and a window to the world for the whole family – it’s not a purchasing decision to be made lightly. Not to mention the fact that you’re likely to spend a rather large sum of hard-earned dough in the process. Fear not – we’re here to help you decide. Here are five important things to think about before you swipe that plastic to ensure your new TV will bring nothing but joy into your home (ok, and maybe a couple of disagreements on what to watch).
- Size matters
If you’re a fan of action-packed movies or nail-biting sporting events, you already know how important the size of the screen is. Consider the space into which your new TV will fit, and take measurements of the wall area or cabinet it’s going to sit on to make sure that you’re being practical about its size. How many people will be watching the TV at the same time? Now opt for the largest screen size that will fit comfortably in your lounge (and your budget). Generally, anything between 55 and 65 inches is a great all-round pick according to price, performance and how close most families sit to the TV.
- Is it digital-ready?
South Africa’s digital migration is upon us and by June 2019, you’ll either need a digital-ready TV that can transmit digital signals or a Set-Top Box to decode digital signals for your old, box-style analogue TV set. The benefits of investing in a digital TV include crystal-clear image quality, excellent sound and a wider range of channels. Ask the sales assistant to show you their range of digital ready TVs when making your selection.
- Does it have a 4K screen resolution?
Resolution refers to the sharpness of the TV picture, usually in terms of horizontal lines of pixels. Ultra HD/ 4K sets have four times more pixels than current Full HD screens. That’s as many as 2 160 horizontal lines, or 3 840 x 2 160 pixels. The result? Super-sharp, detailed and lifelike images, even on large screen sizes. For this reason, a 4K resolution is becoming increasingly popular because it’s a much better choice if you want to future-proof your investment – Skyworth’s G6 model was created with this in mind; it’s basically an Android TV made for the future.
- What will you be using your TV for?
Apart from the obvious activity of chilling out to watch your favourite shows, what else do you want to be able to do with your TV? Will your kids be using it to play games? Will you be streaming shows on it? All of these preferences will impact the specific features that will attract you to buy a certain model over another one, so it’s wise to do your research, either online or in store, before you say ‘yes’ to the device. Also, look out for at least four HDMI ports at the back of the set as these tend to get used up very quickly, especially if you are using accessories like a sound bar.
- Does it include cutting-edge technology?
From Google Voice Assist, allowing you to speak to your TV, to rich connectivity via Bluetooth, selecting a TV that has advanced capabilities makes for a smarter TV and one you aren’t likely to need to replace in a few years’ time. With Android System 6.0, an easily updatable operating system, the G6 TV is your best bet when it comes to constantly upgrading your TV without forking out money every time.
