All of the LCD screens are made by either Samsung or LG, I can't swear to it, but I believe Vizio's are Samsung screens. The difference once the various grades of panels each manf. makes are evened out (i.e. the Sony XBR uses a better grade of Samsung display than the EX series), the difference is the engines (chips), sync technology, etc. The Visio line saves money by using less expensive engines and offering less features. Which can make them a excellent buy for those wanting basic television and movies. If you are a heavy duty gamer you may want to spend more on a better engine, thus your question about delays etc. may indicate you want a more up market set.
