This post is not about TV devices but I dont know where else look for help. I bought Philips monitor 196V3LSB7/00 LED, it`s came with standard VGA cable and I dont noticed any problem. I decided to buy DVI cable then problem came, some functions from SETUP menu on Monitor became unusable, "AUTO, H.Position, V.Position, Phase and Clock" options are darkened and can`t be used. That`s not the problem with VGA cable. How can I fix this problem, I have installed all drivers from CD which came in original package, problem is not resolved.

Sorry for my bad English, I will appreciate your help.
