Ever wondered recently what this new 4K logo (by Sony) in the movie theaters is all about? Well, it is the new digital cinema standard with a screen resolution of 3840×2160.
This new resolution is already creating a lot of heat and debate in the industry.
Who will actually benefit from these ultra-high resolutions, you decide for yourself.
Let’s first recap various resolution standards – sorry for dry numbers:
I. Standard Definition:
480p : 640×480 = .3 Megapixels (aspect ratio of 4:3)
: 854×480 = .4 Megapixels (aspect ratio of 16:9)
II. High Definition:
720 : 1280×720 = .9 Megapixels (aspect ratio of 16:9)
1080p : 1920×1080p = 2.1 Megapixels [p stands for progressive scan]
1080i : [i stands for interlaced scan]
1920×1080i = 2.1 Megapixels (aspect ratio of 16:9)
1440×1080i = 1.6 Megapixels (aspect ratio of 4:3)
III. Ultra High Definition:
4K (2160p) : 3840 × 2160 = 8.3 Megapixels (aspect ratio of 16:9)
8K (4320p) : 7680 × 4320 = 33.2 Megapixels (aspect ratio of 16:9)
Now let’s discuss some applications:
Home Use (TVs & projectors)
On the home front, new Ultra High Definition TVs have started to appear in the market…initial price range is between 20,000-25000. Sony, LG and Samsung are the first ones to come out with UHDTVs. So, whether you need these or not, UHDTVs will get pushed into the market. An average buyer might have to wait for 4-5 years (or sooner if prices come down faster) before these will become affordable.
Not sure if there is any advantage to having an Ultra HD TV. A CNet article explains why 4K TVs are stupid for home use. At an 8-foot viewing distance, you’d need something like a 102-inch screen to see the pixels on a 1080p picture, so looks like there’s really no point in having 2160p at home.
If you have a home theater and want a 4K projector, look no further… you can buy one at Amazon.
NVidia and NASA are using 4K projectors to improve the image quality in flight simulators.

For office use, keep an eye on this technology, engineers might find ultra-high definition monitors very interesting for design work.
