I know this qustion has no doubt been asked a million times before, have tried a search but the results are far too many to trawl through.

Have recently set my DVD player to use progressive via Componant, previously it was interlaced via RGB Scart.

I know progressive is meant to be better, what should I be looking out for, and how is progressive better?

My kit is in my sig. thanks in advance.

In my understanding only CRTs use interlaced signals all other displays and projectors need deinterlace the picture at least this is true for LCD.

The problem with interlaced signal is a certain flickering. This is why 100HZ CTRs were introduced (including a whole set of new problems like the visible track of a flying ball, etc.)

On a DVD is either movie material (24 full pictures per second) or video material (50 half pictures per second in PAL). Your display shows 25 pictures per second ( I know this is weired but this is how it works) and the de-interlacer has to make sure both source materials are displayed properly:
Either put the video pictures together to a full picture or convert the 24 to 25. Actually there should be flags to trigger this on the DVD but most of the time they are not set properly. This is the progressive output.

In general: A good display/projector will do a better job then a standard DVD player.

So with my kit I am better with progressive via componant?

You have two choices:-

Send an interlaced signal from the DVD player and let the screen de-interlace it (flat panels are inherently progessive)

or

de-interlace the signal in the DVD player and send the progressive image to the screen.

I would say there is a good chance that the de-interlacer in your £2000ish screen will be better than the one in your £200ish DVD player.

The absolutely, above all else, most important question is...



Which looks better to you?

Thats the thing, I cant really tell to be honest, but just wondering what is the advantage of me switching to progressive via componant over interlaced via rgb scart?

MY BenQ W100 has PS. As it has two component inputs, I attached a player with interlaced component and another with PS in the player on the other component. I couldn't tell the difference.

In my understanding only CRTs use interlaced signals all other displays and projectors need deinterlace the picture at least this is true for LCD.

While that is true nowadays. My Panny PTAE100 does not have it so, I had to do it in the player.

Hmm this is all so confusing!


progressive via componant will give me a more detailed picture however interlaced via rgb scart will give me a smoother one?

is that correct?
