I’m a bit of a stickler when it comes to video quality, so I often notice a difference when I switch between watching cable TV and a streaming service like Netflix or even YouTube on my TV.

Overall, streaming video from a service like Netflix looks sharper than cable TV, despite the fact I’m watching both in the same 1920 x 1080 resolution. 

Indeed, whether you notice it or not, there is a difference between the two in the way the video is being displayed on your TV.

See how the two differ and why internet streaming video looks better than cable TV:

Cable TV from a cable box comes in 1080i resolution, where the “i” stands for interlaced scanning.

Whereas internet streaming videos from a device like Google’s Chromecast or Roku, or even some Blu-Ray DVDs come in 1080p, where the “p” stands for progressive scanning.

Both display the same 1920 x 1080 resolution, but cable TV’s 1080i video can look slightly fuzzier than a video stream’s 1080p video, especially during scenes where there’s a lot of movement.

Above, the video on the left is using interlaced scanning, and the video on the right is using progressive scanning.

The video in this GIF has been slowed down to show you the effects of interlacing. It’s less noticeable when the video is playing at normal speed, but it’s still there and makes the overall picture look less sharp than progressive scanning.
