KansukeKojima 0 Report post Posted January 10, 2008 I've been playing a few games recently... and they ask me if I would like to turn on progressive scan for my television... well, since I'm poor, and have a t.v. that likes to flicker unless I wham it, I have never expierienced it... so yeah... could someone please tell me what progressive scan is?

rvalkass 5 Report post Posted January 11, 2008 Progressive and interlaced are two ways to make the picture appear on your TV. This is easiest to explain with an example. Imagine an HDTV with a resolution of 720 lines. That number is the number of horizontal lines which make up the picture (i.e. the vertical resolution).In an interlaced system, for each frame, all the odd lines are drawn first, then the even ones, then the odds, then the evens... That can create a flickering effect if your eyes are sensitive enough, or if your TV is a bit slow and drawing each frame.A progressive system draws all the lines in order (1,2,3...) for each frame. This means that visible flicker is reduced, the picture appears smoother, and it has a perceptively higher resolution. The problem, however, is that you need to transmit more information faster to get the image to appear. This was therefore not possible until HDMI and component cables came about.
