I have been using dual-monitors for some time now, like 5 years. When I first started it was a Samsung Syncmaster with a resolution of 1440x900, my second monitor has always been 1280x1024. Two years ago that monitor stopped working, then I got my first HD monitor, it is a 21.5" AOC e2250Swda. It might not be the best monitor, but I really love it so far. And when my local computer store had one in store last Friday, I picked it up to replace my old 1280x1024 monitor which was starting to gave some trouble. So far I have been enjoying it, everybody in my class says they are to small, but I love it so far. I have my laptop also hooked up to my main monitor via VGA, and use it as a extension. I will post a picture of it since I have been moving my set-up around the last couple of days. My desktop is being replaced this summer, it is a HP Pavilion P6340.nl, which I will be replacing this summer due to age. It has helped me always really well, but on some occasions it has started showing some problems. My laptop that I use for school is a Sony VAIO VPCEJ3Q1E which I love to bits, the only downside to it is that it doesn't have a 1080p screen, but that wasn't really around on laptop in 2012 when I bought it.
