Im very cautious around acer, I have a 23.5 inch 120hz that does faint ripples like heat rising at 120hz, so I sent it to them, it came back with them telling me it was the dvi cable, and they had replaced the cable. So it arrived and they had replaced my dual link cable with a standard dvi cable, which was obv no good. What was even worse that after buying another cable the problem was still there, so I sent it back and then they sent it back to me saying that it was fixed and it came back with cracked casing so I didnt accept it and it went back again, then I got it back but they had took my dvi cable. I phoned the manager up about that and he said he'd send one out, he never did. And when I tested it 6 months after firstly sending it off it still had the exact same issue. I was getting no where and just gave up. But if this acer works well enough in 10 days of having it and I dont detect anything wrong itll be fine. Ive took 9 days off work so I can give it a good test, because I never ever want to go through that again.
