Re: new monitor, which should I get?
Get the more expensive one which is the 22" monitor. It has support for the 1080p HD spec. It has DVI support too and at the same time, less energy consumption with better performance than the other monitor. Despite having DVI support, I don't know if it ships with the DVI cables or not. I don't see it in the pictures.
But if $50 is a big deal to you, then the other one will do just fine too.
