I had my 600m now for about a month (first, Laptop) and at first I didn't notices any rippling or anything when I was moving the screen around/closing it, however now that I have had it for a month and you could say that's it's gotten borken in ( I take it to class and to work) that I am starting to see some rippling on the right side of the screen and the top(it just about goes away as soon as the screen stops moving). My question is this normal to have rippling in parts of the screen when it's moved or in spots when I touch on the back of the panel to ajust or clost the screen?
