i also have a new h240. When I change the reslution for example to 1600x1200 my screen is not wide but the picture is not deformated. Under not wide i mean there are black two black columns on both sides of the screen.
Is your screen always wide also when your resolution is normal?
1. is your laptop always so hot on the left side? my fan is always running and i assume that the temp is min 50-60°C.
2. Did you already try to play a dvd or normal video? When I run a dvd for the first time, the laptop froze suddenly with whistling sound and nothing helped except hard reset. It happen only randomly but I don't know what is the reason.
