Most 4K projectors offer at least 4,096 x 2,160 pixels of resolution and because they typically offer projection area sizes that totally dwarf all but the largest 4K TVs, this is where you really notice the difference between UHD and regular HD content.
With a projector showing native 4K content or even upscaled 1080p HD content, you finally get to experience picture clarity in your own home that imitates on a smaller scale what you’d find with a large UHD public theater screen.
One that has gained some headway is Google’s VP9 4K video compression codec, which the company still uses in compressing the 4K content streams found on its You Tube video service.
Most premium 4K TVs today are compatible with both VP9 and H.265, though not all models offer both.
Now, in terms of TV 4K systems, this resolution isn’t even entirely noticeable unless you enjoy a very large and thus very expensive screen or are sitting abnormally close to your TV.
However, when it comes to projectors, the power offered by 4K really does become visible.
Furthermore, buying a 4K TV gives you access to future connectivity specs and future visual specs that will come in handy as broadcasters catch up to the new technology.
Also, the illumination capacities of most UHD TV brands use particularly powerful versions of technologies such as LCD panels illuminated by LED backlights in the form of local dimming or full array dimming systems that dramatically improve picture brightness and contrasts.
4K film camera prices are dropping too and a lot of new content is being filmed and distributed based on this platform.This puts it on the top of the current scale of digital resolutions in which the bottom is occupied by standard definition TV (450X540 pixels), HD with 720 pixels and full HD at 1080p.In simplest terms, if you measure HD resolution by vertical pixel height (720p, 1080p) then 4K UHD can also be called 2160p.Furthermore, new sources of 4K content via Blu-ray discs in ultra HD resolution is finally here in 2016 and movie titles are coming out at a steady pace in this new format.And as we’ve already covered above with streaming content, compression and transmission codecs such as HVEC are going to make sure that both 4K broadcasts and 4K home theater systems are mutually compatible for delivering UHD content even if bandwidth conditions for most homes don’t improve significantly.
The Benefits of UHD 4K TV 4K TVs don’t just come with the benefit of enormously enhanced resolution.
