What Makes 4K Different?
A 4K television has 4K resolution, which is Ultra-High Definition or UHDTV. That means it has four times the resolution of a 1080p Full HDTV.
Why Does Resolution Matter?
A television picture is made up of pixels. Resolution refers to the number of pixels on the screen. The more pixels there are on a screen, the smaller the pixels appear. The smaller the pixels appear, the clearer the picture will look.
The key to HDTV’s popularity is its smooth, crisp lines and well-defined picture. This allows you to distinguish small things like pores on an actor’s face.
If you have a 1080p full HDTV, it has 1,080 horizontal lines of pixels from the top to the bottom of your screen. On a 50-inch TV, this pixel count or resolution is enough to give you a beautiful picture if you are sitting at least five feet away.
Isn’t 1080 Full HDTV Good Enough?
On a 42, 50 or 60-inch television, 1080 Full HDTV has a high enough resolution to create a clear and detailed picture. If the TV is 84-inches, such as some of the new 4K models, the picture quality wouldn’t be as sharp as it is on the smaller televisions.
For these seven-foot TVs, some experts believe UHDTV or 4K is your best bet for the highest definition. Since most people don’t have the room for an 84-inch television, these may not be practical for the average homeowner.
