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.
