Re: 27" Monitor
Apart from that I think monitors designed specifically for gaming have more advantages as very good response time than traditional led TVs. Also from my previous exp I think horizontal tearing in games would be much more noticeable on TV when playing with sync off.
IMO TV's are not meant for gaming. The response times are bad. The resolution remains same and gets streched on the TV making it look worse.
Basically, if you sit at a desk with the monitor directly in front of you, a TV isn't the best choice. If you sit a few feet back from the monitor, a TV could possibly work, assuming you can find one without much input lag and a decent response time. Most TVs have significant input lag, because they try to fiddle with the signal to make it look better.
