Booted up laptop this morning and the bottom 1/3 of the screen was black and the task bar was just above it. In the black zone the cursor disappeared. On my external monitor I had full screen. I fiddled with the monitor display settings and now I only have a narrow band of black at the bottom of the laptop screen. Ext monitor is fine. Is my laptop monitor dying? Font settings also seem to be smaller. I don't remember doing anything yesterday that would create this new display...

Thanks
