    I've got a 15" MBP and trying to get a brand new Acer S231hl monitor working properly. It's attached to the MBP via a Star Tech Mini DisplayPort to HDMI adapter. The problem is I can not get it to display the full resolution (1920x1080). In W7's Display menu, it correctly shows my MBP monitor as well as the Acer, and the Acer is set to 1920x1080. But there are still black borders around the picture and there's nothing I can do in Windows or on the Acer's hardware menu to fill out the entire screen. I've tried putting the MBP in clamshell mode but it won't wake when I use my mouse or keyboard after it's gone to sleep, so I can't say for sure if that will fix the resolution issue.

    Not having any problems at all with this set up in Mac OS 10.6.7. The Acer displays at full 1080p without any adjustment on my part (gotta love Macs!) So the issue is not the adapter or the monitor I don't believe but some esoteric system in Windows. If anyone has experienced this or has any ideas I would be forever in your debt, thanks.

    Just discovered that the AMD driver that comes in the Boot Camp installer package has incorrect overscan settings for external monitor resolutions - read on the Apple forum to download the latest Catalyst Control Center and adjust the overscan setting within that program. That worked great.

    I'm having the same kind of problem with my MacBook that has an Intel Graphics Media accelerator chipset. Accept when I open the intel driver, it doesn't even detect that I have an external monitor connected.

    I know for a fact it works because in OSX the monitor is connected at 1080p. I'm wondering if you have any suggestions.

    Thanks.
