A Bigger TV Always Means A Better Picture, Right? Wrong.
The clarity of your picture depends more on how many pixels per inch your screen has to work with.By Leah Becerra | January 16, 2016
Here's a question: Will a bigger TV have a better picture?
Not necessarily. The most important measurement for TV shoppers to note is pixel density, usually labeled as pixels per inch or dots per inch.
So, let's say you've got a 1080p, 32-inch TV. It looks pretty good, right? That TV's pixel density is about 68 PPI — that's 68 pixels per inch.
