Companies must be full of excitement with CES underway because the announcements are taking place well before the actual show begins.  One of the newest innovations to be announced are 480Hz LED HDTVs.  They should start showing up from companies such as Vizio and Samsung.

480Hz technology was featured in plasma HDTVs up until 2009, when 600Hz sub-field drive technology replaced it.  With LED HDTVs, it’s an upgrade from the 240Hz technology being used in older 2009 models.  The idea behind the higher number is simple:  higher hertz means a smoother picture.

It’s all a bit of a shell game since the eye can only notice up to a certain refresh rate.  After that it’s all a marketing arms race.
