HDMI2/DVI input named PC:
Please note that naming HDMI2/DVI grays out many settings including amp only when connected to a PC. If you attempt to name this input as PC when connected to a NTSC source such as STB, Tivo, or game console it doesn't lessen the amount of input lag nor disable certain settings such as AMP.

What was it that you all were saying that this tv has NO input lag? For those educated gamers out there this is your answer to whether or not this tv is any good for gaming and or in my opinion good for anything really. As you can see even with game mode on this set has atleast 60ms of lag which is EXTREMELY poor especially for a mode that should be the fastest of all modes. I went out and spent almost a hundred bucks just for the cables to perform these tests so that people will have the facts about the lag on this set and not a bunch of useless opinions from people that don't know what they are talking about.
As a side note I didn't even take any pictures with AMP on that would REALLY make the numbers even higher I'm sure, maybe I will try that tomorrow.
Test done with Imac in maximum resolution mode of 1680 by 1050 Mirror mode via DVI to HDMI on HDMI2/DVI input.
A comparison test done on a Sharp 26 inch HD LCD with no lag to show reliability of testing setup:

I just started reading this thread, so sorry to to comment on this late and I'm reading as much as I can, but this isn't really a valid test. You do clearly show the settings of the TV do have some impact on the input lag and people who say "there's no lag" simply don't notice it. But another factor to consider is the Apple's built-in LCD itself should itself have lag, so it may be that the Samsung may have even greater lag that reported in the screenshots.
But a bigger factor skewing this is this test assumes output from the video card to both displays is perfectly synchronized. This probably isn't the case because the way video cards work, even if you set them to clone the display, the output to each display almost always comes from separate frame buffers and they may not necessarily be perfectly synched up. It takes time for the image from the primary display buffer to be copied to the secondary display buffer. So depending on the video card and settings, it may mean the Samsung may be faster or slower than what's reported.
The true way to test input lag would be to take a single source, split the signal, and send one to a CRT and the other to the Samsung LCD.
