Hey got a quick basic question. If a TVs native resolution is 4:3 what happens when you throw 16:9 like a widescreen dvd or a game thats 480p at it? Will it distort to fullscreen or will the the input(console, dvd player) put it right so its good on the output(TV)?
It really depends on the TV you're using. Some will let you stretch the screen and distort the picture, others will simply black out the top and bottom of the screen and show the 16:9 movie within the margins.
I'm just getting in to all of this though, so I'm sure other members will have better info
4:3 or 16:9 is the screen type (Wide or Normal) not the screen resolution.
Normal (SD) 4:3 sets are 480 resolution and so are SD Wide Screen Sets.
The difference comes in when you are talking about High Definition TVs (HDTV). HD is 720 or 1080 for either 4:3 or 16:9 sets.
So back to your question if you play a Wide Screen DVD in your 4:3 set you will see shadow boxes on the top and bottom of the picture. Now you have options of magnifying the picture on most DVD players to it doesn't look so bad. Some TVs have options to adjust this also.
The best thing to have is a Wide Screen TV so you can play both Standard or Wide Screen movies with little or no problems.
Most newer DVD players will have a 4:3 or 16:9 screen option to set depending on the screen type of the TV you have.
