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)
