1080p remains a staple in TV technology.
The first step: Learning about 1080p.
You’ll see that term in a lot of places, so let’s dig in.

What Does1080p Mean?
Digital displays consist of pixels, which are arranged in rows or lines.
1080p refers to a display that has 1,920pixelsarrayed horizontally and 1,080 pixels arrayed vertically.

Referred to as pixel density, this is the total number of pixels displayed on the screen.
In digital camera and photography terms, it’s about 2 megapixels.
Still, neither comes close to the megapixel resolution of many inexpensive digital still cameras.
That’s because it takes more bandwidth and processing power to produce moving images than still images.
However, it will be a few years before 8K technology becomes mainstream.
In short, the p stands for progressive.
This refers to how pixel rows (or lines) display on a TV or video projection screen.
How 1080p Relates to TVs
1080p is part of the high-definition (HD) video standards landscape.
However, a growing number are now 4K Ultra HD TVs.
This process is referred to as upscaling.
The more precise guess the TV makes, the better the image will look.
TV broadcast signals are another matter.
While 4K TV broadcasting is on the way, it’s not quite mainstream yet.
