BenQ G2420HDBL 24" monitor. Up to 1920x1080 resolution DVI input only (but I will include a DVI-HDMI cable).
It works perfectly for a few minutes but then suddenly turns off and won't turn back on again until you unplug it for another few minutes. It was stored in a damp loft for a while so perhaps it's to do with that - it worked fine before that.
