    Hi.
    PAL resolution is 768 x 576 pixels.
    1/ Does this mean a large screen tv has the same amount of pixels as a
    portable?.

    2/ SVGA has a resolution of 800 x 600 only slightly better tha PAL
    resolution. Why does it look so much better?.

    Thanks for your help

    ** No way is that PAL broadcast resolution - there are no pixels as
    such.


    ** The larger screens like 68 cm normally have better resolution of
    detail than 34 cm.


    ** Because there really are 480,000 individual colour pixels.

    The bandwidth available for a colour PAL broadcast signal is only
    4.5 MHz or so while a PC monitor has many times that bandwidth for *each*
    colour signal.

    ** Actually the frame rate it is only 25 Hz - the field rate is 50 Hz
    and interlaced to reduce flicker.
