    Just what is TV resolution?

    I'm just asking this for giggles - what is TV resolution?

    How many pixels are on a tv? Is it 400x300, or 320x240, or 640x480, or is it different depending on the TV???

    Maybe too late for this. Heck. Anyway, here's a good read.

        Here is a little extract from the article link I gave:

        The biggest misundertanding when it comes to PC video enthusiasts is the idea of horizontal resolution. When we talk about PC monitor resolutions we are talking about pixel resolution. So a PC screen may have a resolution of 800 x 600 which means 800 pixels (dots) going across horizontaly and 600 pixels going down vertically.

        TV's engineers, however, only speak about TV resolutions in terms of the number of lines going across not down! Why? Because all TV's have exactly the same amount of lines going down, but not all TV's have the same amount of decernable dots going across. For example, an American TV picture will always scan exactly 480 lines down, but the number of dots going across will always depend on the quality of the TV and the signal broadcast to it. A VHS video will only offer about 210 dots across while a TV station may offer about 330 dots across!
        I mean no offence here. Just wanted to straighten out things.
