    TL;DR: Looking for an affordable dual screen output solution for my Late 2016 Razer Blade that runs off the dedicated graphics card.

    I'm wondering how I can do dual screen output on the new late 2016 Razer Blade with the GTX 1060.

    I read that there's only one display output physically routed on the previous early 2016 Razer Blade (You can either use HDMI or USB-C as a display output but not both). Has that changed for the new late 2016 Razer Blade?

    You can see Linus here in this video at 2:26 outputting to two screens and it looks like he's driving one via USB-C and the other via HDMI on his late 2016 Razer Blade.

    Another option buying a USB-C to Display Port adapter and then daisy chaining with Display Port 1.2 compatible monitors, however I read that when you do this it's all driven via the integrated graphics card and not the dedicated graphics card. Has anyone ever tried this with a specific adapter and had it work via the dedicated graphics card?

    A side note to this option, apparently you can buy an HDMI to Display port active converter and do this exact daisy chaining method, this will let your drive those two screens off your dedicated graphics card. However HDMI has a more limited bandwidth compared to Display Port. So it seems like there's a trade off between bandwidth and GPU, it would be nice to have a purely USB-C connection that runs off the dedicated graphics card. ​

    Hi black shadow!
    I believe this is because the USB-C port is connected to the integrated graphics, while the HDMI port is connected to the dGPU. No adapter you buy can change the fact that the hardware is wired separately. I suspect Razer did this to make the Core work properly. They probably assumed if people wanted more monitors they would just buy a Core.

    Anyways, you did not mention any details about the additional monitor. What do you plan to do on it? What is the resolution and refresh rate?

    The reason why I ask these questions is because there's definitely ways to connect additional monitors, but they aren't going to be gaming-grade connections.

    For example, you can use a USB to [Video Output] adapter like this or use a hub like this. You can connect 3+ monitors this way if you want.

    Another solution is to convert from HDMI to DisplayPort, and then use a Display Port splitter adapter to plug into multiple screens.

    The reason I know this is because I had the exact same problem a few years back when I was trying to connect 7 monitors to my laptop..


    Hope that helps!

    Hi Raijin!

    I plan on doing all sorts of productivity work on these monitors such as video editing, CAD work, and programming.

    The monitors I have are two Dell 1080p monitors that both have Display Port (I believe DP 1.2? Not too sure on the specs, I don't have them on me ATM.)

    I don't think I'm going to game on dual monitors, however it would be nice if I can.

    I did some more research and it seems like MST doesn't work on an HDMI to DP 1.2 active converter.

    So in conclusion aside from getting the Razer Core with a new graphics card it's either you can only have 1 external screen utilizing dGPU or 2+ external screens all utilizing the Intel internal GPU on the processor. Kinda disappointing for a $3000 CAD laptop. :frown_:

    Hey there. Ah, thanks for catching that. I never actually tried that option myself because I went with something else. So HDMI => DisplayPort => MST Hub is out of the question.

    However, you may have missed my other solution. You can use USB to DisplayPort adapters. They are essentially like mini external graphics cards and will give you solid performance - 4K @ 30hz, QHD (2560 x 1440) and lower at 60hz. It can handle 1080p just fine.

    Since it seems like your monitors can't do over 60hz, a gaming-grade connection is not necessary. The above product should work for you and is perfect for your productivity work. As I said in my previous post, you can connect 3 or more monitors to your laptop this way.

    For my problem, I ended up using a miniDP MST hub, the HDMI port, and a few USB to DP adapters to get everything running.

    Oh wow thanks! I thought there would be no point for this option since there's already USB-C, I definitely under estimated the power of USB 3.0.

    What would be better, video out through the USB-C port or one of those USB 3 things you're talking about?

    You're very welcome!

    Regarding which is better - I don't think it matters in this case. It sounds like you just have standard 1080p 60hz monitors (correct me if I'm wrong) so either would work. It only starts to matter in situations where you have higher end monitors and you plan to play games 2560 x 1440 @ 120 frames per second.

    In fact, I think it might be possible to do both at the same time but I'm not 100% sure. These adapters act like mini external GPUs so they will drive the displays on their own without using the Blade's integrated or discrete GPUs. You can keep adding/using more displays until your CPU isn't up to the task anymore.
