It may seem like size is all that matters when it comes to buying a monitor, but there's a lot going on under the hood. This video from Techquickie tells you everything you need to know about LCD monitors as fast as possible.
We've run through your five favourite monitors before, but it's important to know what you're looking for if you're shopping around. Gamers may want a "TN" monitor because they have higher refresh rates, while graphic designers will probably prefer an IPS monitor, which has more accurate colour and better viewing angles.
Check out the video above to see an insanely quick rundown of the different types of monitors so you're better informed the next time around. If you want a bit more info, Coding Horror has a pretty good article on the subject too.
