what does it mean if a lcd tv has a resolution of 1366x768,1024x768xga,1280x720hdtv...which is better out of these and why? contrast ratio 3000:1, 4000:1, 1,200:1 how is this rated and what makes one better then the other one?
also how about brightness- is the higher number always better?700,500,400, etc.
thanks in advance thanks
