I had a monitor that had a few stuck pixels, I sent it back under the distance selling act because it was faulty and 'not to my expectations' as well as not performing 'as it should'.
Got a full refund
Yeah, you can do this and completely ignore whatever standards about stuck pixels I guess.
Does that mean that I have to assume everybody else is doing it and that I'm almost certain to get one with broken pixels because people just send them back every time?

Ironically that makes a retailer who states that I have to pay costs to return the item more desirable, because then at least people have to pay to take another throw of the dice.
