It's about a frame of lag--just like I told you in the first place.

The octopus was very scary.
How are you getting this info? Have you done the bodnar test with it, 240p test suite, etc?

Even fudoh himself says they're lag free units

The Time Sleuth makes the Bodnar obsolete. :) How did I get the information? That should be obvious. I chained the Time Sleuth tester through a DAC, to the VSC 300, and to the TV.

It's closer to one frame than a half a frame. 13 milliseconds if you must have the precise number.

Fudoh also gave a good estimate. If you feel the need to call it about half a frame, go right ahead. It's more than half and less than a full frame, so that's a fair estimate. Also, Fudoh didn't have an easily accessible lag tester available when that was written. (That makes his estimate even more impressive, because he identifed it was less than a full frame the hard way.)

It's a bit surprising that I am writing another reply. I thought the photo would put the matter to rest.
