20ms?
Aqui un parte de review que esta en AVforum sobre input lag:
parece que es mucho mas que 20ms.Gaming Performance
As readers of Steve's LW550T review will know, it didn't score particularly well when it came to input lag, with a latency between 90-100 milliseconds. However, acting on our feedback, LG have issued a software update to address the issues and we duly updated the 650 in eager anticipation of the promised improvement. Having taken 15 measurements, in GAME mode - connected via HDMI, we're pleased to announce the 650 measures better, but only slightly. Our measurements were all, unfortunately, in the 80-90 millisecond range and LG could probably do with taking another look. We are confident that LG will crack it eventually and we certainly know they're keen to do so!
