    Hey i need to often connect laptop to dual external displays. Rather than using the 2 mini display ports or 1 hdmi 1 mini display port, thinking using thunderbolt3 output with a thunderbolt 3 to dual hdmi adapter or perhaps a thunderbolt3 dock. Does the thunderbolt 3 output on this or other similar clevos support dual monitor output?

    Since it does support one monitor output like the P775DM3-G, i'd say it does a dual monitor... test it and let us know

    Cant test without buying a dock or adapter which dont want to do without knowing first. Read not all thunderport 3 outputs support dual display output, depends on laptop maufacture. Pretty sure should be like p870dm3, p775dm3...Anyone knows if thunderport 3 output on these clevos do dual output?

    Daisy chaining displays is supported. What displays are you wanting to use?

    Daisy chaining would be nice but i believe need certain kind display port compatible monitors for that?
    My 2 monitors have hdmi and vga inputs

    Goal is to hook up 2 monitors via 1 output on laptop if possible

    Also curious to know if the regular non-thunderbolt type c port can output a single display out?

    Thanks

    Not natively accelerated but USB3 docks can software render the output on USB type-c outputs.

    Yes i know of those, but want to avoid since they offer poor graphic performance and put load on additional system resources like cpu.
    So i know what kind of cables/dongle to buy, to be clear, thunderport 3 port capable of single display out only?

    Is yes and since from what u say seems regular usb c port cant send gpu's display out i guess my only option would be two cables in either of these ports (hdmi, mini display port1 and 2, thunderbolt3 port) correct?

    Thanks

    It depends on the dock you get, a single displayport link can be paneled up to go across several displays so long as the total resolution is not bigger than the output can manage. Also your VGA and HDMI displays require a clock signal which needs to be actively generated compared to displayport native displays.

    Hello there,

    You absolutely can! However, to get Display-port signals through the Thunderbolt port, there is one change you must apply: Under the UEFI setup utility (launched by F2 on system startup, navigate to: BIOS > Advanced > Advanced Chipset Control > DDI Control and toggle this option to DP to TBT, from the default value DP to eDP.

    Suggestions: Ensure that Thunderbolt support is indeed enabled, and that security mode is set to Unique key (Default) OR Legacy (if you plan to dual boot with Linux and use daisy-chained devices over Thunderbolt 3 + DP MST functionality). If you set the Thunderbolt option in BIOS to DP++ only, ONE of your mDP ports on the chassis will be disabled, and as such, its' not recommended.

    Extra notes: As from Linux 4.15, it will be possible to authorize Thunderbolt 3 devices and even utilize networking capabilities. See this document for more details.

    If you need Thunderbolt 3 dock recommendations, let me know and I'll give you a few pointers.
    At the moment, I own a Cable-matters Thunderbolt 3 dock daisy-chained to an older Cal-digit Thunderbolt 2 dock linked by a bi-directional Thunderbolt 3 to 2 bridge (by Startech). The advantage of this dock is the cost and expansiveness it offers. For one, there's no point buying an expensive dock with charging capabilities as you can't use that feature on Clevo notebooks. Remember that only an SKU configured with the appropriate Power Delivery (PD) Thunderbolt firmware can take advantage of this (up to 100W max), such as the current generation Macbooks.

    I can confirm that this is possible.

    Inferring from the current generation builds with dual Thunderbolt 3 ports, you have the top of the line controller, a "DP" (Double Port) version that uses a PCIe 3.0 ×4 link to provide two Thunderbolt 3 ports (DSL6540). You can confirm this by using a tool such as AIDA64.

    Thata great to hear! :)
    Yes recommendations would be great. I need two video outs and doesnt matter what kind as can just use adapter. Also 4 usb 3.0 slots. Preferrable one that can also work without power supply
    Thanks!

    Are the displays you have displayport themselves?

    Well, for starters,

    All current generation Thunderbolt 3 docks need a power supply.

    Only passive USB type C adapters run without one.

    Now, for my recommended picks:

    1. CableMatters Thunderbolt 3 dock: This dock presents a pair of USB 3.x type A ports and a spare USB Type C port in the rear. One DisplayPort output is available, and so is a headphone out and mono mic in. Why its' recommended: Dual Thunderbolt 3 ports (ideal for daisy chaining and for extra display adapter connectivity) as well as the availability of a spare Ethernet port. Nothing beats its' value for its' price. A note on this model is that there are similar identical SKUs based on it, such as the version from Startech, and these variants are often more expensive without any additional value.

    2. The Plugable Thunderbolt 3 docking station: A bit on the pricier end, yet meets your requirements for the four USB ports above. Has charging capabilities too. It lacks a forward-facing USB Type-C port like some of its competitors. While there's no HDMI port on the back of the dock, Plugable includes a free DisplayPort-to-HDMI adapter. However, unless you have a Thunderbolt 3 monitor, you'll need a Thunderbolt-to-DisplayPort or Thunderbolt-to-HDMI cable to attach a second monitor.

    3. The OWC 13-port Thunderbolt 3 dock: For these with money, and then some to splurge. This is the go-to build for these that want an elegant, Mac like design without sacrificing on the ports and the optional power delivery option (which you can't use on Clevo anyway).
    Port configuration:
    Front Ports:
    SD card slot, headphone jack, USB 3.0
    Rear Ports: 4x USB 3.1 Gen 1, S/PDIF Out, FireWire 800, Ethernet, 2x Thunderbolt 3, Mini DisplayPort

    What I'd recommend based on your requirements: Take either 2 or 3. 3, if you can pay for its' markup and need legacy connectors such as Firewire and SPDIF.

    Products I cannot recommend:

    Any dock that needs a software utility to manage explicitly, and clones of other docks (see 1 above for the explanation). These include docks from the likes of the IOGear Thunderbolt 3 docking station, Belkin Thunderbolt 3 Express dock and the Elgato Thunderbolt 3 dock.

    You might be better off getting some decent DP monitors rather than paying for some of the active cables is always something to consider.

    One of my monitors is pretty old and considering replacing. Would one dp monitor give me ability to do the dp trick? Perhaps 1 monitor with dp in and out to daisy chain into second monitor with a dp to hdmi adapter?
    Or need two dp monitors?

    Thanks

    Hello there,

    What you're looking for is DisplayPort MST , which permits daisy-chained multi-display setups.

    A recommendation on this front would be to use a DisplayPort MST hub, rather than rely on any specific monitor's inbuilt functionality.

    Good examples of MST hubs are illustrated below:

    1. The full DP to multiple Display Port outputs MST hub that takes one DP source and enables independent display port output per monitor. You can then extend, clone or set up display walls (via Nvidia's Surround display setup, Intel's Collage Mode (where supported, particularly on Optimus systems where the outputs are driven by the Intel GPU) and AMD's Crimson software's Eyefinity Facility). This adapter is useful if you're dealing with thunderbolt docks or GPUs that offer one or more Display Port outputs.

    2. The miniDP to multiple DisplayPort outputs hub. This is useful on configurations that offer mini-Display Port outputs, such as the plethora of Clevo laptops and devices that support Thunderbolt 1 and 2. This is perhaps the fastest way to get MST up and running without a Thunderbolt 3 dock on current generation Clevo systems.

    3. Either of the above configurations, terminating in HDMI ports. This module is useful where the user has a single mini or full DisplayPort outputs targeted at multiple HDMI monitors, as is often the case with many commodity display panels that often lack Display Port capabilities.

    Disclaimer: I have owned and used Startech's MST hubs in both production and lab environments, and as daily drivers, experienced no major issues with them so far.
    However, with monitors that often support MST natively for daisy chaining, workarounds are often needed to make them work as advertised, and I speak from experience with Dell's hardware.

    The second issue concerning workarounds is even trickier if you're running alternate operating systems such as Linux, and as such, is strongly recommended to stick with standards-compliant MST hubs.

    Note that I did not recommend any USB type C passive adapter above.

    Related, some of the cheaper USB type C hubs are quite capable. For some use cases, one might not need a Thunderbolt 3 dock where a cheaper alternative in a well made type C hub would do just fine.

    Take a look at this sample, for instance: https://www.amazon.com/gp/product/B075R28DVM/

    There, you get virtually all the ports you'd want compensated for, including a dedicated passthrough charging port.

    So long as it's not trying to use display port over usb from the computer.

    You wont get 3d accelerated output then but it's perfectly fine for extended desktop/spreadsheets etc.
