I'm looking to buy a new PC widescreen flatscreen monitor to replace my old 4:3 CRT and would like to know what specs I should be looking for, eg what measurements are considered as good contrast ratio, image brightness, response time, resolution, number of supported colours, refresh rate, etc, to make sure I get one good enough for my needs? (I never needed to consider those terminologies before.) I'll be using it for playing games, watching videos (DVD, Blu-Ray, DivX, etc) and photo viewing/editing, so these uses will need a monitor of higher specifications than one I'd use for normal home office use. Is there much noticeable difference between image brightness of 250 cd/m2 and 300 cd/m2 ? Are LED screens the way forward rather than LCD? HD monitors are 1920 x 1080 resolution whereas my old 4:3 CRT allowed me to play games at 1900 x 1600 resolution, so will I be losing anything by switching over to a 1920 x 1080 screen which seems to be lower resolution? Sorry, my current monitor is a CRT which I purchased more than ten years ago, it came as part of a ready-built PC, so back in those days I never needed to know the meaning of things like contrast ratio, response time, etc. Any advice please would be greatly appreciated. Thanks.
