Hi 
as per the user manual i m supposed to see OSD options such as brightness(nits) and ability to change the bottom LED color like  a separate color when in g sync mode and another one when not in g sync mode. as for brightness i only a brightness with a  max value of 100 while this monitor supped give max 400 nits. i tried the acer chat option but the agents are not responding properly. dose anyone knows how to fix this please? i was following the below review
