    is 5:4 the same as 4:3?

    I am looking into ordering a 4:3 monitor for a classroom. The whiteboard is 4:3 and the existing monitor is 16:9, which is causing the picture to be stretched. I am struggling to find a 4:3 monitor, and can only seem to find 5:4 ones.
    Would a 5:4 monitor work ok with a 4:3 board? Are they the same?

    This is the one I was looking at: HANNS.G HX193DPB 19" LED LCD DVI Monitor | Ebuyer.com
    The board is a SmartBoard is a SB580.

    5:4 and 4:3 are different, but very close in all reality.

    For example, 1280x1024 is a 5:4 ratio. Using the same width at 4:3 would be 1280x960. This means that if you were to play a genuine 4:3 source on a 1280x1024 5:4 display, there would be a small amount of letterboxing (32px above, 32px below).

    It's a very small difference in pixel aspect ratio, but not one that anyone is going to notice. IMO, a 5:4 monitor will work just fine paired with a 4:3 IWB.

    If you really want a matching ratio, get a display with a native resolution of 1024x768, as that is a genuine 4:3 resolution.

    Native 1024 x 768 is something I've not seen in some time. As said, 5:4 is close, but not quite, that said, you should have little to no problem with the SB and such a monitor.

    If you're interested. I can do you 19" HP screens with the same Res as that Hanns.g one (1280x1024) for just £45 Ex

    There's not much in it...



    5:4 is slightly wider than 4:3.

    Have you not got a 1024x768 monitor somewhere else, not connected up to a smartboard, that you could just swap for the widescreen monitor?

    1280x1024 monitors are fine - monitor or projector will each handle a slightly funky resolution, so either run a 17" monitor at 1024 x 768 (looks smudgy but the projector looks ace) or at 1280 x 1024 (monitor fine, but text isn't as clear on the projector).

    We run them at 1024 x 768 where the monitor is a second screen alongside a 1080p monitor, and at 1280 x 1024 where it's the only monitor.

    @ICTDirect_Dave Could you send me a quote for that please? I think we'll go for a 5:4 from what everyone's saying it won't be too noticeable anyway @spadam unfortunately not, all widescreens!
