Hi, I picked up a MBP 15" core i7 high res laptop on Friday. I actually ordered one of those mini displayport -> HDMI awhile back (was going to get a mini, decided no), however when I hook it up to my plasma it won't adjust the resolution to 1920 x 1080, I checked "display" in system settings but it won't let me push it past the native resolution of the laptop screen. Any suggestions how to get around this? Also it mentions on the website it can push sound over HDMI now, I wasn't able to figure that out either. Any help is appreciated, thanks.
