Well, my old monitor had 2 deadpixels but this didn't bother me, what did was the double vison since it was a 25ms monitor and silly me not knowing anything about monitors just jumped in because the price was good. After time It started to bug me because it was going slow in games/movies wasn't so much as browsing but you could notice it a little so I wanted to return it - I was thinking what could my excuse be? I couldn't blame it on the deadpixels because it was something like 4+.
So I un-screwed the back and whent into the circut board and removed a power thing on the actual board that looked like a little black tower which was very small and when putting it back together I removed a wire which was easy visable.
In the "Why are you returning it section" - I added - There is no visual on this monitor, it wont turn on - I have had a look at the connecters which I got with the monitor but nothing although when I was just checking around the back for lose cables or faults I found that there was one lose, since I don't know anything about it - I sent it back, this may or may not be the problem.
Oh yeah they refunded the cost. I was hoping for some compensation costs for the monitor and for my troubles
Anyways hope this helps
