Comment 1 for bug 50389

We pick the second-highest resolution for CRTs; this is usually a sensible mode. Detecting LCDs vs CRTs is non-trivial and while we do try to detect it, it's not an easy task (so often goes wrong). Rejecting as I believe the current policy is the best we can currently do; you are always free to change the resolution using the "screen resolution" control panel option.
