Actually all the times appear identical here as well. Not sure what to make of it.
Here's my speculation
[I have not read the lag thread [yet?]:
I think laptops max out at about 100Hz for refresh rate. Even at that rate, it's 10ms per frame. I don't really know how fast the data can be pumped to the TV, but the bottom line is that while the software clock is busily updating every millisecond (perhaps), the displays are only taking the updates every once in a while. So despite quicker camera shutter response, the numbers on the display are more persistent than they are in the software.
Do you know what the refresh rate is on the laptop (check monitor prefs) and on the plasma?
