    Hello
    This is probably a dumb question but I'm a newbie. If I buy a FRONT projector, what mode will I be watching cable TV? 4:3 vs 16:9 stretched...TIA

    Almost all projectors project in 4:3 mode, but what you see is in whatever aspect the source is sending out. So if the source is 16x9, you'll have black bars on the top and bottom (where nothing is being projected). So for normal cable, it'll be in 4:3.

    .. and if you go for a digital projector with native 16x9 capabilities you will have the option of viewing 4:3 material boxed inside the 16x9 or stretched.

    Or you can buy a lens that will unsquish anamorphic material

    It also depends on your screen shape (4:3 or 16:9).
    I use a 16:9 screen, actually 1.80 Aspect Ratio (because I only watch DVDs, not TV).
    In my CRT projector, I have two different memories (same height, but different width), one for 4:3 material (full height of the screen, with vertical bars on each side of the picture) and one for widescreen material.
    If the DVD Aspect Ratio is 1.85, the picture just fills the screen. (I use a little stretch to fill the 1.80 screen)
    If the Aspect Ratio is 2.35, there are horizontal bars at the top and bottom of the picture.
    If the Aspect Ratio is 1.66, there are small vertical bars on each side of the picture.
    My DVD player has a built-in scaler that digitaly converts letterbox DVDs into an anamorphic output, so, as far as the projector is concerned, every widescreen DVD is anamorphic. That's why I have only one memory for all widescreen DVDs.
    Otherwise, I could create additional memories with different vertical geometry to strectch letterbox DVDs.
    If you go with a 4:3 screen, it's the opposite.
    You set all your memories (4:3 or widescreen) for the same width, but with different height (full height for 4:3 and letterbox material, "vertical squeeze" for anamorphic material).
    Hence, 4:3 material is "full screen" and any widescreen material has horizontal bars at the top and bottom of the picture.
