I just received my new iMac and and after waiting two weeks and there's a ton of stuck pixels on my screen :'( I boot up this monitor and while the screen was still black I noticed it has almost no light leak at all. It's perfect until I pulled my chair closer and got comfortable on my desk and noticed all the stuck pixels all over the screen. I went through 3 rMBP's in 2012 and ended up keeping the last replacement with a stuck pixel on the top left corner. Fast forward this year a pixel got stuck right in the middle of my screen; I gave up exchanging it because it was such a hassle going back and forth. This 27" iMac is massive and I really hate to go through multiple systems again... just my luck. Here are some pics I took on my iPhone. I could have easily pulled out my Macro lens on my DSLR but my iPhone could reveal the pixels. This picture was taken on one side of the screen.
