Buy a TV or a dedicated monitor I have 2012 model mac book air. At home i want to have a 22"-24" screen for work purpose. I was wondering if i should just buy a dedicated monitor or a 24" flatscreen tv with HDMI input? My work is generally  related to coding with some photo editing of family photos and watching movies. Also, are there any specific points which i need to consider while buying the monitor/tv so that it is compatible with my air.
Generally, monitors have a higher pixel density because they are intended to be viewed for closer up. I'd recommend an HDMI, DVI or Display Port monitor because of the generally higher sharpness and contrast and more accurate colours over TVs.
