Ultra HDTV Buying Guide

The next generation of high-definition television is here, and it offers the richest, most-detailed TV viewing you’ve ever experienced. Tune in to your options with this Ultra HDTV buying guide.

Ultra HDTV 101

Ultra HDTV is a catch-all term for the newest generation of high-resolution flat panel TVs. You'll also hear it referred to as Ultra HD, UHD, UHDTV, 4K UHDTV, 8K UHDTV and, simply, 4K. The names can be confusing, but you won't have any difficulty seeing the benefits. Ultra HDTV sets provide dramatically better picture quality than the full HDTV sets available today. To be precise, the resolution of 4K Ultra HDTV is four times higher than full HDTV, and 8K Ultra HDTV is an astounding eight times higher. 8K HDTV has yet to arrive in the consumer market, but you can easily find a 4K Ultra HDTV set to suit your family's needs. 

Ultra HDTV Buying Tips:

  • The best Ultra HDTV screen size for most home viewing environments is 55 inches to 65 inches
  • Ultra HD sets are available with LCD or LED displays
  • Choose a high-quality HDMI cable for the best Ultra HD picture
  • The shorter the HDMI cable, the better the picture quality
  • Most Ultra HDTVs support 3D technology
  • Many Ultra HDTV models have voice and gesture technology which can replace a remote control


4K Ultra HDTV +

The resolution (number of pixels) of full HDTV is 1920 x 1080p. With 4K TV, you get a resolution four times higher, or 3840 x 2160p. The result is a crystal clear, vibrantly colourful viewing experience. The first generation of 4K sets is now available and prices are coming down steadily. The ideal size of a 4K TV for home viewing is 50 inches to 65 inches, though you can find sets ranging from 39 inches to a whopping 100 inches and larger. Ultra HD sets are available with LCD and LED displays. Highly regarded, but pricier, OLED (organic light-emitting diode) displays are coming soon.

8K Ultra HDTV +

Also known as Super Hi-Vision TV, 8K TV has a resolution of 7680 x 4320p, which is eight times that of full HDTV. 8K TVs are not available yet in the consumer market.

3D Ultra HDTV +

Most 4K sets support the 3D format, allowing you to watch your favourite 3D movies in the comfort of your home. 4K uses something called passive 3D technology. Considered an upgrade over active 3D, passive 3D sends a full 1080p signal to each eye. Potential advantages include reduced eye fatigue and lighter, less expensive passive polarized glasses (instead of the heavier active shutter variety).

Smart Ultra HDTV +

Smart TVs are designed to connect seamlessly to the Internet and to wireless electronic devices like Blu-ray players and tablets. With your smart Ultra HDTV, you'll be able to view the latest 4K movies released on disk and stream new original TV series from on-demand streaming services. A major benefit of smart TVs is their ability to automatically download updates to apps and even TV firmware.

Voice and Gesture Controls +

Here’s where Ultra HDTV really becomes futuristic. Imagine being able to change channels, control volume and picture settings and resize your display without touching a remote. Many 4K sets offer exactly that capability via voice and gesture control technology. Some models allow you to activate a web browser and surf for content without touching a button or screen. Another bonus: you needn’t worry about losing your remote control or having the batteries run out.

4K Upscaling +

Much of the current available content is still formatted in regular HD. However, some Ultra HDTVs have a built-in workaround known as 4K upscaling. It’s a rendering engine that raises or “upconverts” HD content in real time to something close to 4K quality. As a result, the image on your screen is more detailed and the colours are richer.

4K Blu-ray +

A new 4K standard (4K/UHD) for Blu-ray is approved but still under development. Industry experts say there are still technical obstacles to overcome before any movies are released in the Ultra HD disc format. If you decide to take the plunge and buy an Ultra HDTV, you can still watch your existing collection of Blu-ray discs.

Ultra HDTV Maintenance Tips:

  • Never leave your Ultra HDTV on while it is not in use
  • Don't use ordinary household cleaners to clean your Ultra HDTV
  • Use a dry, soft cloth and very gently wipe the display screen
  • Place your Ultra HDTV in a clean, cool, and dry space away from heat and humidity
  • Use a surge protector to keep your Ultra HDTV safe from power surges

Ultra HDTV Content

For cable subscribers and HD antenna users, access to 4K content is limited for the time being. The major network broadcasters are still catching up to this new technology and need more time to agree on standards and roll out 4K channels. However, some 4K TV manufacturers are providing libraries of 4K content for rent or purchase exclusively by their customers. When it comes to online streaming, some major on-demand streaming services and other developers of original programming are now filming new episodes of their shows in 4K. In addition, online content providers are in the process of re-mastering vintage movies to display in 4K.

Ultra HDTV Viewing Distance

One of the main benefits of Ultra HD is the depth and detail of the picture. This allows you to sit closer to your 4K screen and feel like you're in the middle of the action. When viewing an HD set, you would typically sit eight to 10 feet away, but the extraordinary detail of a 4K display is best appreciated at a viewing distance of about 5.5 feet for an 84-inch screen and 3.5 feet for a 55-inch screen. You’ll still see a great picture from a conventional viewing distance, but the whole point of Ultra HDTV is to get right up close for a true cinema experience.
