Instruction: Answer the given question using the supporting document.

Input:
Question: Two questions:  1. Will this dock support two monitors?  2.  To what connection (plug-in) on my Toshiba Satellite L650 Model Number PSK2GU-ORCO2L
Document: I recently pre-ordered a Surface Pro 3. At the time I ordered it, the Microsoft dock for this model was not available but I probably wouldn't have ordered it anyway. The dock for the prior model was around $200 and didn't support two monitors, which is important to me. The MS solution to multiple monitors is display port daisy chaining which is not supported by my monitors.
I deal with port replicators all the time. This model worked right out of the box. Other models (specially Targus) have issues with the power supply, internal USB hub firmware, etc.The Toshiba port replicators are also very good.Make sure that the following software is up to date to ensure that your port replicators works at it's best:1. DisplayLink Core software / Drivers2. Video/Display drivers3. USB 2.0 and 3.0 Drivers4. Chipset drivers
It's the perfect docking station. You can pre-setup your desk with keyboard, mouse, two monitors, speakers, and LAN connection to be ready for your laptop to operate like a desktop. All you need is to plug in its USB cable and your AC adaptor, and you're good to go. It's also great for LAN parties for friends who just want to bring their towers.If Plugable would add a universal AC adaptor, it would really make the item an all-in-one dock.
After reading reviews for a number of docking stations, I bought the UD-3900 for my Toshiba Satellite laptop running Windows 7 Home Home Premium (64-bit). Unfortunately, the DisplayLink software for the AOC USB display I purchased to extend my laptop's display was incompatible with the J5 Ultra Station I had (recently purchased) been using. :(Reviews played a sizable role in my choice to purchase this device, especially those describing Plugable's helpful customer service.
I needed a dock that supports Windows8 and found this, so I will give my two cents about the two laptops I use this with.1. Thinkpad running Win 7Everything works as expects, very easy to install and everything works once I plug in the USB cable from the dock to the USB3.0 port on the laptop.2.
I recently bought a Surface Pro 2 (running Windows 8.1) with the hopes of using it as my daily driver. The Surface's lack of ports is a real problem when used as a desktop machine especially to a guy like me that measures his manliness by the number of monitors he's using. There is the official Surface Deck, which is a sexy piece of machinery, don't get me wrong, but it's $200, not available right now, and itself has frustrating ports.
I have two of these. One for my Dell Ultrabook and one for my Toshiba c55 laptop. They are connected to different monitors, a 6 year old HP and a new Samsung. They are also connected to two different wireless keyboards, a Microsoft one and a Logitech one. I run one with a wired Ethernet connection (into the Plugable) and one just via WiFi. Both laptops run Windows 7. I bought the first one in mid-Feb 2014 and just got the second one.
I needed a docking station for surface pro. I researched and compared this product with the Toshiba docking station and decided on the plugable product. Plugable's  website gives quick responses to questions and are very willing to help. They stand behind their product. Before purchasing I asked about how the transition to windows 8.1 would be, and they responded within the hour giving me a very good description on how to make the transition. Many reviews I saw about docking stations complained about various items.
The product plugged in and worked well with my Win 8.1 machine - only one problem, it doesn't work with touchscreen monitors which defeats the purpose of having a dock if you have a touch screen unless you have a lot of peripherals you need USB support replication for.
This really works great. All I need to plug in is a single USB3 cable and this handles two monitors, network, and the peripherals like keyboard and mouse. It's so easy to come and go with the laptop now.I installed the drivers before I even received the unit, so when I plugged it in, it just worked. I've very happy with this.I'm using this docking station with Windows 8.1.
Answer: It will support two. One via HDMI, the other via DVI or VGA (can't recall which).
