The 4k Craze

What is all this talk about 4k? Ive ran a 5k before. Not the same thing? Nope this is not about exercise. Actually the complete opposite.

Theres been a lot of chatter around the social networks about Netflix testing 4k streaming. What exactly is “4k streaming?” First of all current TV models support up to 1080p. This is Full HD. If you were to count all of the pixels vertically there would be 1,080. A normal Full HD TV would be 1920 x 1080 and have just over 2 million pixels on the entire screen. That’s a lot! Well it used to be anyways. New technology looks to place 4 times as many pixels on the same screen. Hence the name 4k also known as Ultra HD. The new screens with Ultra HD will be 3840 x 2160 with a whopping 8.3 million pixels.

Why would we want or need so many pixels? The obvious answer is because it makes things clearer and sharper. While that is a basic answer there’s more to it then that. When you have a 32 inch FHD TV the picture is sharp, but place it next to a 60 inch FHD TV and the picture loses some clarity. This happens because the pixels on the 60 inch TV are larger. The 32 inch and 60 inch screens maybe almost double in size but the amount of pixels on the screen hasnt changed. This is where 4k makes its money. This is the value that Ultra HD brings to customers. Albeit rich customers, as the TVs with 4k are running as high as $3,000 and for PC monitors as high as $4,000. That’s a pretty hefty price tag, but back in 2006 32 inch HD TVs were in that price range. Now you can get a decent model for as low as $400. In just a few years I should be able to afford one of these. Maybe by then we will have hover boards like Back To The Future.
