Thunderbolt 3 not able to display?

Anonymous

Hey there, having huge problem with my new adapter.

I can't seem to make my laptop display on my monitor with a thunderbolt 3 to displayport adapter, here is the Info I can give:

I have a gaming laptop and used a HDMI cable to plug it in to a monitor.

The Monitor is 144hz and g-sync capable, so I decided to ditch HDMI and go for DisplayPort.

I have recently bought a Thunderbolt 3 to DisplayPort adapter (LAPTOP<--TB3---DisplayPort-->Monitor)

I know that my computer is TB3 capable since there is the little "lightning" sign on top of the input area.

When I connect the Adapter, it emits light, I therefore know Its being powered, though there is no signal received by the monitor.

-Every time I connect the TB3 into my laptop, it says "thunderbolt device functionality might be limited" and that links me to a very unhelpful Windows support page telling me to literally verify that I plugged it in well.

can someone help me fix my issue? I really want to be able to use TB3's full potential to display my laptop's screen.

I am running Windows 10 Home 64bit version 10.0.16299 build 16299

Laptop is Dell's Alienware 17r3

monitor is an Acer Predator

adapter is a Startech TB3 to DP

(drivers are normally up to date)

To resolve the issue, please perform the troubleshooting steps found on this link on how to Fix USB-C problems please browse below for the USB or Thunderbolt device functionality might be limited section.

No to be rude, but that's exactly the link I was talking about, these are the "Solutions to try"

<ul> <li>Make sure your PC (or phone) supports the same USB-C features as the connected device.</li><li>Make sure the cable supports the same USB-C features as the connected device.</li><li> Make sure the device or dongle is connected directly to your PC (or phone). </li><li> <div> <div> Make sure the device or dongle is connected to the USB-C port on your PC (or phone) that supports the correct Alternate Mode. For example, if you're connecting a Thunderbolt Alternate Mode device, make sure it's connected to the USB-C port on your PC (or phone) that supports Thunderbolt. </div> </div> </li></ul>

for the first point: How does one check this?

for the second point: How does one check this?

for the third and fourth: I'm pretty sure I can plug in a cable into my PC, and as mentioned before, the USB-C input in my pc does have the Lightning sign, same as the adapter.
