As usual with technology, you get what you pay for.
I've been using a Samsung 2494SW for the last year and a half, and I think it's a great monitor. Reviews were pretty good on this 23" model, the price was right, and it has rather small bezels. I thought going with another Samsung was a good choice.
Upon first setting them up, right away I noticed a stuck pixel on the left screen. Great. I got it exchanged rather painlessly, which is nice, however just today I now found a new stuck pixel on the right screen. 2/3 bad monitors is not a good sign.
I have another grievance as well - these monitors have absolutely no way to be repositioned. No tilt, no swivel, no height. Generally that isn't so bad, except that they come stock with a very slight tilt back, which means they don't line up exactly flush. Well, again, no big deal - ideally I'd get a triple monitor stand anyway. Except here's the big kicker - these monitors have no rear mounting brackets at all.
All in all, the only thing these monitors really have going for them is the price. I have until Jan 2 to return them, so we'll see about that. They perform well in game, though. Is the very low cost worth the small hassles?
