    I believe they have kept the x240 the same width as the x230. Does this mean one could attach an x240 screen (and panel) to an x230 to achieve a higher resolution? Is there anything to stop doing this?

    Yes - the X240 uses eDP as the display-connector to the mainboard, instead of LVDS like the X220 / X230.

    A switching of the new panel into the old model would be extremely complicated.

    Would a connector/converter work?

    No, there are several other problems about the UEFI, the display EDID. It is not that easy to do.

    Could you please go in to details? Is it a case (no pun intended) of purchasing a new cable, adaptor, screen and bezel?

    I would really like to do this because I need more pixel width but I prefer the 16GB of my x230.

    - You need an eDP - LVDS adaptor (maybe self made)
    - You need to develop your own display EDID and BIOS / modify both

    On the X220, it would be more easy, since on the X230, the UEFI-BIOS has an digital signature (because of Secure Boot) and can´t be easy modified / flashed. But for both it is extremly difficult.

    Definitely. No question there.
    There *might* be a shortcut here, I can't say with a 100% certainty since I haven't tried it, but my course of action would be:

    a) Get the EDID reading out of the old HD LCD

    b) Reflash the EDID of the 240 panel with that info (this might have to be done within a 240 unit, though)

    c) Verify whether the machine will boot with the new screen. If it does there's no need for a BIOS mod. If it doesn't...oh well. There is.
    Agreed. Personally, I wouldn't even attempt it on a X230, for a plethora of reasons.

    Unknown generic panel.

    I wouldn't touch it with a 30-foot pole.

    Caveats stated above likely still apply...
