first thing's first. CRT telly's usually have a cracking picture so you are going to notice a change there.

depending on your price bracket for a new telly there are flaws.

cheep LCD. don't even think about it if your into sports as the 'lag' will drive you nutz.

good LCD (LED back lit) better as they usually have better driving software and panels but still 'lag'.

Good LCD (LED edge lit) ok'ish but sometimes suffer from the same problems computer screens do and highlight the edges more due to the light being more focused in that area.

pros/cons of LCD/LED great colours and brightness but tend to look a bit false and depending on price range have lag. when i say lag i mean fast moving objects like golf balls, foot balls, runners will have a 'trail' or 'shadow' to them. LCD/LED are cheep to run and consume very little leccy.

now on to plasma.
plasma TV's don't suffer from lag but aren't as bright or vivid as LCD but they do give a lot more tones of black. so if your watching a horror you can see the monsters in the shadows where LCD will just be a black hole. if your watching footy you wont get the 'trails' or 'shadows'. plasma cost an absolute fortune to run. mines consumes around 300 watts an hour where an LCD will be about 70.

now onto digital TV. this again depends on the signal and hardware. cheep nasty freeview boxes are just that 'nasty'. virgin HD is cracking with no dish on the side of your house to get blown about by the wind. i'm not saying anything bad about Sky but i'm not saying anything good.

HD is the doggyzz and more like a good CRT/analogue picture.

you are looking to get a TV with 1080p. 3D is good and yes your 3D telly will still show 2D. to watch 3D you have to have 3D compatible hardware e.g. bluray player or 3D set top box (Sky/Virgin) and the glasses, depending on the brand the glasses are either passive or active.
