Message: <blockquote data-quote="RetroDude" data-source="post: 10032" data-attributes="member: 187">Considering that most video data sources are NOT at 120hz, the television is basically making up "difference" frames between existing frames of data.Do either the X-Box or PS3 have the ability to output anything other than 60hz video signals?Not the resolution.. the frame refresh rate. Two totally unrelated things.If the data source is 60hz, this will certainly cause a lag... The set has to read two frames at 60 Hz, calculate a "difference" frame, then display them all in sequence.Frame 1 from input ... loaded into 1st frame buffer...Frame 2 from input... loaded into 2nd frame buffer...Set calculates the difference betwen these two frames...Displays frame 1...Displays frame 1.5...Displays frame 2...Repeat!It HAS to cause lag, just due to the nature of the higher refresh rate!You can't calculate an intermediate frame till you have the following frame!When watching movies or cable/satellite sports, it results in smoother action, as moving objects are less "jerky" on screen.Lag would be totally unnoticable unless you had two different sets side-by-side displaying the same source video.For Games without 120hz refresh rate?Critical fail.Spend more for fancy television, have more lag problems. Bummer!</blockquote>
