I have had this specific dock for about 4 months and I chose it because of the two digital outputs. It has 4 USB 2.0, DVI, and HDMI ports on the back, and 2 USB 3.0 and a 3.5mm jack input for microphone and headphones on the front.

Initially, I used it with a VGA monitor and a second one from the laptop's output again with VGA. Everything was fine, but one output of the dock remained unused. Eventually, I bought a Dell 22" full HD monitor and connected it with HDMI to the second output of the dock, and that's when the problems started. There was an incredibly long delay in response, I could see the window closing frame by frame. The laptop I was using was a Lenovo t430 with i5-3320 2.6GHz, SSD, and 16GB RAM with Windows 10, it was unbearable! I tried it on a desktop with i5 3570 3.4GHz, 12GB RAM, and SSD with Windows 7, and it worked better but there was still a delay. I tried it on an HP laptop with i7 at 2.6GHz, SSD, and 16GB RAM with Windows 10, and so far it had the least delay in response. I downloaded the latest drivers and used cables with ferrite cores. What else can I say, it's a complete disappointment. If you have to have a €1200 laptop with 8 cores for it to work, I'd rather use a desktop. I assume it will work well on low-resolution screens, but the manual states that it supports two 1920x1080 monitors. The conclusions are up to you.
