Windows 10: Will a USB-C /Thunderbolt Connected Monitor Work During POST?

Graphics displayed via the built-in graphics from an Intel CPU or a graphics card installed in a PCIe slot get initialized at boot so that you can see the display prior to booting Windows. Graphics adapters that are connected via USB require a Windows Driver from DisplayLink and therefore are not initialized until Windows is loaded. However, I have no experience with native USB-C / Thunderbolt graphics. Does anyone know if these initialize at boot or will they only work once Windows is booted?

I'm looking at a monitor that has a native USB-C connection but I want it to work before Windows is loaded so I can do things like go into the BIOS without needing to connect a different monitor.

You need to use one of the following when connecting a monitor: HDMI, VGA, DVI or newer standards such as USB-C with thunderbolt.

 

Usb - c / thunderbolt issue


Hi,

Recently purchased a Razer, currently transferring files over from my ATOM RAID 2 TB EXTERNAL SSD, USB-C / Thunder-Bolt 3 Drive to another External connected via USB 3 via Windows 10.

Any time I attempt to transfer files, the ATOM RAID begins to transfer and then the speed shoots to 0 and the drive is disconnected, then re-connected on its own accord it seems.

When I attempt to run Crystal Mark Test on it, it makes the disconnected Audio as the Test begins, with the test never being able to start.

Through the only process of elimination I have, I disconnected the drive and connected it via USB 3.0, with the cable provided and tests were fine and Crystal Mark was able to begin and finish. Unfortunately I don't have any other USB-C or Thunderbolt External Devices to test the port out.

The SSD worked flawlessly on my iMac 5K Thunderbolt 3 Drive.

I have formatted the Drive to NTFS, several times but that has not changed anything.

I have perused Device Manager, but I cannot find anything in specific detailing Thunderbolt or USB-C, only USB 3.0 and the device hence also appears under a USB 3.0 nomenclature. I haven't used Windows in sometime, so I'm unsure if USB-C is labeled USB 3.0 regardless.

Attached are some screenshots.

The Drive is labeled VIOLENCE, even after failure of copying files, it remains connected it seems, or it disconnected and reconnects instantly. I hear two audibles, so I'm assuming the latter.

Hopefully I can resolve this today and hopefully it is not a Hardware Issue, my Razer Blade has been flawless otherwise

As you can see on the FINAL Image, Windows Devices labels is as USB 3.0, even though it is connected to the USB-C port

 

Sapphire Thunderbolt 3 and USB-C Accessories Now Available

SAPPHIRE Technology is launching today a new series of Thunderbolt 3 and USB-C accessories for both Windows and Mac users. The New lineup features products that extend display connectivity with popular HDMI and DisplayPort connectors, Power Delivery adapters for simultaneous display output and battery charging, and a traveler's 4-in-1 travel dock.

Thunderbolt 3 is a modern connector with staggering bandwidth of up to 40 Gbps. This speed of a single compact port enables users to extend the capabilities of their ultrabook and use additional peripherals, extra displays, Ethernet cards, or storage devices; and deliver power to their device at the same time. Thunderbolt 3 is an interface of USB-C that does it all.





Dual DisplayPort or Dual HDMI dongles - extra displays for Ultrabooks
With extremely thin ultrabooks and Apple MacBooks lacking any display outputs, users need to rely on Thunderbolt 3 port connectivity. However, monitors with direct Thunderbolt input are still limited in number and remain expensive. The New SAPPHIRE Thunderbolt 3 to DisplayPort 1.2 and Thunderbolt 3 to HDMI 2.0 dongles aim to address that issue. Certified by Intel and compatible with macOS, these adapters feature 2x outputs of the given type and allow users to connect two displays with up to 4K resolution @ 60 Hz. In addition, the DisplayPort dongle can drive a single 5K display @ 60 Hz with dual link (Windows only).

USB-C 4-in-1 Travel Dock - hassle-free travel connectivity
Users don't want to sacrifice the mobility and comfort of their ultrabooks while traveling, but often need additional connectors for business scenarios - at meetings, presentations, or when only a wired network is available. Fortunately, the USB-C connector can drive multiple peripherals and SAPPHIRE today launches a convenient 4-in-1 Travel Dock to make use of that technology. Users can utilize it to extend the connectivity options of an ultrabook and get a set of extra ports. Enclosed in a stylish white casing are: USB 3.0, HDMI 1.4 (up to 3840 x 2160 @ 30 Hz), VGA (1920 x 1200 @ 60 Hz), RJ-45 Gigabit Ethernet and USB-C for up to 60 Watts of power delivery.

USB-C to HDMI or VGA display dongles with Power Delivery Charging
Often only a single USB-C port is available on the thinnest of ultrabooks, forcing the user to choose between powering the device or connecting a peripheral. With SAPPHIRE USB-C display dongles with Power Delivery Charging, a single HDMI or VGA monitor as well as power source can be plugged to the notebook at the same time. HDMI adapter supports resolutions up to 4096 x 2160 @ 60 Hz, while the VGA one drives 1920 x 1200 @ 60 Hz. Both adapters have a USB-C power input port that takes up to 60 Watts of power.

All these ports offer simple plug and play functionality and work out of the box on Windows 10, Apple macOS and Chrome OS.
