That's not the same lag. I'm not talking about the time it takes for the TV to completely change pixels -- that lag happens after the TV has decided to put the image on screen, and is largely not a big deal -- as long as the image has started changing, the player can understand the new scene.

I'm talking about the time it takes for the TV to tell the pixels to change.

I don't think a monitor needs to buffer the full image before you display it just because it's analog data. It really just depends on how the internal bandwidth is setup on the tv vs how the data is sent to it. (AKA if each pixel is updated in order or if each line of TV is updated in parallel etc.) Worst case you might update the immage left to right but receive the signal top to bottom.
