I'm sure someone has mentioned this, but don't forget your rights as per the Distance Selling Regulations... you are entitled to return electrical items purchased online such as monitors within the 7 day 'cooling off period' after purchase. You don't need to give a reason, it's your right. So if you get one with problems, and they won't replace it, just return it. If you can't live with it. In such cases though, you invariably will have to cover return postage costs yourself.
