watchable

I am planning to buy a Full HD 40" TV for youtube net and gaming. However i am concerned if the resolution of the youtube video is not 1080 but less, will it be watchable on the tv ? Or should i go for a HD ready TV instead ?

Hello TDFer's I wanted to ask, how bad is the letterboxing problem on the 4:3 Mi pad when you play 16:9 movies or clips.Is the experience spoiled or is it watchable ? Would appreciate comments from owner's Cheers! Abhijit
