Sales of 4K or Ultra High Definition TV sets will exceed 330 million units by the end of 2019; a sharp increase from the 2 million sold in 2013, according to latest projections for this super high definition televisions.
However, while the price of those sets has fallen sharply and likely will continue to fall, a report released this month by the US-based Natural Resources Defense Council (NRDC)contended that new UHD models use on average 30 percent more energy than their HD predecessors.
Consumers most likely will buy UHD models over regular HDTVs when it comes to screen sizes 36 inches or larger, according to the NRDC's report. UHD, often referred to as 4K, offers four times the resolution of HDTV, with about 4,000 pixels on the horizontal plane. With this higher resolution will come, more power consumption.
Most consumers do not factor in a TV's energy use when deciding which model to purchase. To help inform their decisions, consumers should look for models that feature the Energy Star logo, which implies a more energy efficient model. Potential UHD customers should also look at the energy guide label and see how the TV rates against others in terms of their annual operating costs. As TVs are not replaced on an annual basis and may last 10 years or more, the savings in electrical costs could be significant.
In addition to consuming more energy, the Ultra-High Definition TVs that you will decidedly pay a premium to own will display its uber resolution only if you are watching 4K content through it and provided you are sitting close enough. The ability to get up close to the screen without the image breaking down is one of the most intoxicating things about 4K. Sitting closer allows the same sized screen to fill more of your visual field, which yields greater immersion. For instance, the 4K computer monitors remain pin-sharp even when you're just a foot or two from the screen.
There is definitely a chicken and egg problem here. No one wants to spend money putting out 4K content until there's enough significant demand for it, and that means 4K sets showing up in homes. But 4K sets are a tough sell if there's nothing to watch on them except regular HD content.
