I guess that I can try it with the Motion thingy off sometime and see if there's any noticeable difference. Up until a couple of months ago, I had a standard def TV and I've not felt any noticeable lag from this one.
Seeing as I've played games since the Pong era on various systems, computers, etc., I would guess I'd be pretty able to tell if my inputs were not being sent as quickly as on the older set. Just an assumption.
The SDTV are usually the lowest in lag input (display), best. The only problem with cathode ray is the times it take to mirror the images since theres no data to decompressed. Its considered lag free.
Technically, every HDTV lag. There's a few way to bypass the lag. You could set the TV at 480? or 720 for a faster display.
Here 's a few approximations in case someone wonder, theres no consensus on the way to calculate, so don't quote me please.
Smallest ms being optimum.
CRT SDTV : 5ms. approximation
CRT HDTV : 7ms. approximation
Computer monitor : 9ms to 30ms,
Plasma : 15ms to 70ms
LCD or LED : 16ms to 70ms
+17ms can vary from manufacturer spec. Based from two years ago.
At 80ms + your remote might rumble/vibrate before you actually hit a wall.
Expert reviewers tend to prefer Plasma over LED/LCD in terms of lag display,
