The G2400W is a 16:10 (1920x1200 resolution) while the new ones are following HDTV standard at 16:9 (1920x1080 resolution). Not much difference because your monitor will compensate and display some black bars when watching a HD video. However, the panel performance is different. For example, these panels are capable for a native contrast ratio at 1000:1 and they are equipped with compensators where they can achieve a dynamic contrast ratio of 10,000:1. The G2400W don't have any. Response time is at 2ms GTG (accelerated) and the color gamut is wider.
