Both of my monitors are 1080p 24" screens. One is a Samsung LCD display and one is a LG LED display. Both use HDMI to connect to a source. At present there does not appear to be any dual HDMI usb 3 docks out there. They all have 1 HDMI and 1 DVI slot so I had to purchase a HDMI to DVI connector on Amazon for about £5 to make sure I could hook up both monitors to the hub.
I've been using it this dock now for over a month so I thought I'd write a quick review for anyone interested.

Apple has finally released the trackpad drivers for Windows 8! It's not as straightforward as I was hoping as the BootCamp 5 install fails but it's quite easy to get it working manually. If you download the bootcamp drivers (http://support.apple.com/kb/DL1638) you might run into an issue where it tells you that "Only Windows 7 can be installed" on your macbook or "x64 installation is not supported". Luckily, all you have to do is run the driver called AppleMultiTouchTrackPadInstaller64.exe and it will update the trackpad drivers for Bootcamp 4 if you have that installed.
