Hello, I've written a couple of months ago a little UDF which uses the AvLCD.dll (third-party-tool) to connect to the G15 Display with AutoIt. It works well, but there are some little bugs and i can't solve them, because the bugs are in the AvLCD.dll. So I createt now my own Script to connect to the LCD of the G15 with the offical Logitech LCD SDK V 1.03 What you need to make it work: Just copy the LgLCD.dll from etc dir in zip file (see in the bottom of this post) in the System32 dir.
