What is interlaced PNG in Photoshop?

Interlaced means that the image is first sent as a coarse image using each 8x8th pixel, then in each pass the resolution is doubled until the complete image is sent. This may give the impression of a blurry image showing up first that then improves in resolution when loading the image on a web page.

Is interlaced PNG better?

> Interlaced images are much more easily view-able. The interlace lets you see the picture before all the data has been transmitted (makes them appear faster and better-looking) and gives you the “feeling” that it is being downloaded faster.

What is better 60Hz or 60Hz interlaced?

60i (interlaced) is less demanding since instead of drawing full resolution “frames” at 60Hz like in 60p (progressive), the graphics card is only drawing half resolution “fields” which means a full frame is drawn when both odd and even fields are displayed.

What is 30hz interlaced?

30i just means that the screen runs at a lower refresh rate but uses refreshing methods that tend to reduce screen tear. However, most media does not support interlaced image processing and 30 Hz is just terrible to look at.
