    Need a display to be used as a digital dash for an open-wheel car (showing gear / rpm etc).

    Currently using one of these, but the brightness sucks, so looking for something better.

    Required:
    - Bright enough to see in direct sunlight (hood / sunshade can be attached)
    - 5"
    - HDMI input
    - Compatible with a Raspberry PI
    - Low power (5V / 2A ideally)

    Desired:
    - Touchscreen (ideally resistive)
    - Weatherproof
    - <£500


    Been looking at field monitors designed for use with cameras, but not sure if they'd be suitable or which to go for.

    Cheers

    Ideally you'd want a transflective LCD, problem is the size. Usually anything under 6" is intended for embedded use and comes with parallel/spi/dsi interface. If you are willing, try searching for lcd and controller separately.
    If you can go a bit bigger, cartft.com has a number of models starting at 7".



    Field monitors will be about as suitable as anything else, they are ~500nits, so should be okayish with sun visor.

    Doesn't the [full-size] pi come with a DSI slot?

    It does indeed and I am using the full-size RPi 3. Have used the official RPi touchscreen which connects through the DSI port in the past.

    Problem with that for this application is that the Pi is mounted about half a foot away and (although I may be wrong) a DSI ribbon cable looks a bit flimsy and unsuitable for outdoor use and the vibrations (and mechanical students) it'll be subjected to.

    It does, but DSI can only be accessed through GPU, and anything GPU related is behind NDA. So as with camera, only RPi Foundation can implement new device support.

    A second-hand braodcast monitor plus a HDMI-SDI converter would probable the the cheapest option that doesn't involve tearing apart a display panel and creating your own backlight, or sourcing random bits off of Alibaba/Taobao (high-brightness panel + panel controller and hope the two use compatible LVDS timings).
    Or you could take a punt on a cheap AliExpress panel that dubiously claims "Over1000cd/m" and "Brightness: 800cd/㎡" within a paragraph of each other.
