  • NTSC vs PAL Borders on Vice for Vic-20

    From Lawrence Woodman@21:1/5 to All on Wed Aug 21 07:55:33 2019
    Hello,

    I've been switching back and forth between NTSC and PAL video modes when emulating a Vic-20 under Vice and was wondering why the borders are so
    much bigger when using PAL. I would expect there to be a small
    difference in the vertical display, but was wondering why there is such
    a big difference in both.

    How representative is this of what would be seen on a real television
    set for NTSC vs PAL displays?

    Best wishes


    Lorry

    It's 525 versus 576 lines. That's roughly 10% difference. But I can
    confirm it looks like way more than 10% between the two modes. It might
    have to do with the aspect ratio but I'm just guessing.
