I have a laptop with a 14.1" WXGA+ screen which, which has stopped working - the panel itself is damaged, rather than just backlight/inverter problems. Being WXGA+, the screen has a resolution of 1440x900 pixels.

I have noticed that there are people on Trademe selling 14.1" WXGA replacement screens (which are of a slightly lower resolution, but the same physical size). Sourcing a WXGA+ screen is quite expensive, and probably more effort than it's worth.

My questions are:
1) If I managed to fit one of these panels to this laptop, will the laptop be smart enough to realise that the screen is a different resolution, and adjust itself accordingly?
2) Do laptops have a standard set of connectors, or do different manufacturers use their own proprietory plugs/sockets etc?
3) Should I even bother? (cost of replacement panel is around $280)
