Repeating this from the ST60 input lag thread:
These are my results. Again, you can see it go from as "low" as 80 to as high as 100+. No picture settings were changed during testing. Game mode is on, every processing element I can think of is turned off.
First test using flatpanels.dk input lag tester: Images show 80 ms, 80 ms, 85 ms, 100 ms
Second test using xNote Stopwatch: Images show 78 ms, 80 ms, 108 ms, 109 ms
If there is a way to get more accurate tests, please let me know, maybe my methods are poor. I captured the stopwatch using video mode on my camera, trying to keep the displays as horizontal with each other as possible. I then paused, and browsed through the video to find clear detailed timings. Other than that, I don't know what else I could do. Again, no settings were changed, and as you can see, I get variable amounts of display lag from my trust old CRT.
Edit: The only thing I can't control is the displays running at different Hz. My CRT is running at 75 Hz and the Panny is 60 Hz. However, vsync is disabled.
At least this is a mostly controlled environment. The sad thing is, HDTVTest got between 40 and 60 during camera testing and only hit 70+ with a Leo Bodnar device. Is it a bad testing method, is it the camera I'm using? Or are the NA models slower than the EU ones? There has to be something wrong with my testing, because there is no way the display should be that high with Game mode on and as much processing turned off as possible. Unless the EU model has less background processes.
