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.
