Frequently Asked Questions


This device is plug and play. It does not use any drivers, and does not require any setup tasks other than plugging in the source (for example, a computer) and the destination (for example, a monitor).


When you troubleshoot issues with a video adapter, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

  • Video cables

  • Video adapter

  • Video source (such as a DVD player or computer)

  • Video destination (such as a monitor or projector)

To test your setup components, try the following:

  • Use the cable, video adapter, video source, and video destination in another setup to see if the problem is with the components or the setup.

  • Use a different cable, video adapter, video source, and video destination in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test your cables, it is recommended that you do the following:

  • Test each cable individually.

  • Use short cables when you are testing.

When you test the video source and video destination, it is recommended that you do the following:

  • Remove the video adapter from your setup and test to make sure that the video source and video destination work together without the video adapter.

  • Test to make sure that the video source and video destination work together at the resolution that you want to use.

Note: In order for your setup to work properly, the video source, adapter, and destination all need to support the resolution that you are using.

The error “Out of Range” normally means that the resolution being output by the computer is not compatible with the display. Try lowering the resolution to see if that helps resolve the issue.  You may need to connect another monitor or restart the computer or source to accomplish this.

Before You Buy

USB-C is a type of USB connector that is capable of supporting the following:

  • Data transfer speeds up to 10Gbps, if you use USB 3.1.
  • Bi-directional power delivery up to 100W, if both the USB host connection and the device support it.
  • Alternate modes, which deliver different types of data at different speeds. For example, DisplayPort Alternate Mode (DP Alt Mode).

If using Thunderbolt 3 over USB-C, the connection is capable of additional features. For example, Thunderbolt 3 is capable of 40Gbps of total bandwidth. For more information, refer to the following FAQ:

Not all USB-C ports or devices are capable of supporting all of the features listed above, or all of the features at the maximum capabilities. If you require a specific USB-C feature, your USB host connection, cables, and device must all support the feature that you require. For more information about whether your components support specific USB-C features, refer to the information provided by the manufacturers. 

This USB-C device requires that all of the following components support alternate modes:

  • The USB-C host connection (for example, a computer and its port)
  • The USB-C cable
  • The USB-C device (for example, a hard drive docking station)

If your host device includes a Thunderbolt™ 3 connection, this USB-C device will work with your host device.

For more information about the modes that your setup components support, refer to the information provided by the manufacturers.

Didn't work with Toshiba or Lenovo laptops

By: Tatcom - 09/24/2017
This adapter did not work with either a Toshiba Satellite or Lenovo Think Pad. Tested cables and monitor and they both worked. Problem is the Startech. The support page on Startech was not helpful. It said the device was plug and play.

Partially works

By: cwing - 11/09/2017
I've used this specific adapter with a new Macbook Pro. I have connected to 3 different HP Envy32 B&O displays, and two flat screen TVs. Display quality is on par for all tested displays, but audio is choppy when only connecting to the display sound. TV audio works fine. After testing another USBC to HDMI converter with the same display audio works fine.

Great simple dongle, works well

By: NickD_CA44 - 05/10/2018
I have tested this USB-C to HDMI dongle on several Lenovo laptops and my Galaxy S8 phone, with different 4k TV's, monitors and projectors without any issues. The dongle comes in a large zip logs bag without any padding or instructions. It must be a very durable product to bounce around a zip lock bag without any issues. The dongle is about the length of a pen and the larger HDMI end makes up about half the length. The HDMI end is made of shiny black plastic which was scratched all over within minutes of handling it. The cable and USB-C end are made of premium soft plastic and the cable is flexible while remaining sturdy. When I connected the dongle to my computer or phone it was immediately detected and started working within 5 to 10 seconds on first attempt then about 2-3 seconds on subsequent attempts. No installation was need and I didn't even need to click ok to anything. This is a great dongle, by far my favorite USB-C adaptor and try to keep with me as much as possible. I have started leaving it in my jacket pocket permanently as it works well for sharing my phone screen. I received this product in exchange for an unbiased review.

Works great until it fails

By: nitrane - 08/30/2018
We bought 10 of these adapters for iMacs in our college and 4 have already failed. They become intermittent having the hdmi output going up/down/up/down etc... We replaced them with a longer Startech usbc to hdmi cable which might reduce the stress on the usbc connector.
