I currently have a 19 inch old school monitor and am gonna buy a bigger one soon as this small one is too hard on my eyes, I need something bigger! I was thinking either 25 or 27 inch. I always assumed that bigger was better but someone told me that the bigger ones are hard on the eyes too for some reason. Do they know what they are talking about? Is too big hard on the eyes as well? What do you guys think?!
