TV resolutions are a jumble of letters and numbers like 4K, 8K, 1080p and UHD, among others. Most new TVs are 4K, but is that the same as UHD? Is a 8K TV twice as good as a 4K TV? Spoiler for that ...

If you’ve shopped for a new TV, monitor, laptop, or game console over the last decade or so, you’ve probably seen the phrase “4K UHD” on most web pages, ads, and product boxes you’ve come across.

Panasonic has unveiled the world's first 4K TV which can show pictures at 60 frames per second. Like all 4K TVs, Panasonic's futuristic set has four times the number of pixels as a standard HD screen.
