Many of us grew up with relatively small, low-resolution televisions as the primary -- perhaps the only -- screen in the home. We didn't think about it at the time, but these displays had a resolution of roughly 480i. That's the number of horizontal lines that are drawn across the screen. The "i" means "interlaced": only half of those lines are changed at a time.
Back in the day, that was the best we had. As screens started getting bigger, the lines became more obvious -- and the picture got worse. The industry has standardized on two primary television resolutions: 720 and 1080.
While the TV resolution battles were being fought, something interesting happened: screens became smaller and ended up in our pockets. Let's take a look at HD screens and see how they'll influence smartphones, tablets, and TVs.
