In my PSP Slim's Connected Display Settings, there's one option which let you choose the output method. The options are Progressive and Interlace. What is the difference?
Progressive and interlaced describe two different ways of refreshing a television screen. Progressive means the entire screen surface is refreshed at once. Interlaced means only half the screen is refreshed. But when I say half I don't mean the top half or bottom half, I mean every second row of pixels.
The reason why this matters, is because when viewing video that contains a lot of movement you will be able to see where half the screen is refreshed in interlaced mode. So progressive would be the solution, however this requires more resources due to the fact that you are handling more information at a time.
What I meant was, that since the whole image is being refreshed, that means all the data that determines what that image will look like, has to be transfered at once, and all the different components of the tv have to deal with this information as well. If it has to do this 24 times per second or more, then there can be an issue. But with todays technology this is slowly becoming a non issue, unless we are talking about 1080p, then many manufacturers still think it is ok to not implement capable hardware.
