Does the inspiron 7577 support external gpu usage
I am aware that the latest version of the inspiron 15 has a usb-c port which is thunderbolt 3 capable. Can I hook up an external gpu to this? I am looking to buy this laptop if it can. If it does support the usage of an external gpu, does the thunderbolt 3 port have 2 PCIe lanes or 4?

I had this same question and found this document. See page 5.

No. The only Dell systems that have external GPU support are the Alienware notebooks.
That doesn't mean one won't work - but it does mean it's more likely it won't than will, and that it's unsupported.

The document says what it doesn’t support. And I don’t see GPU in this. So it means it is allowed?

Yes, it does support Thunderbolt 3 compatible external GPUs.
The Inspiron 15 7577 Gaming Series system supports standard Thunderbolt 3
protocol/features on external graphic docks. However, performance has not been
validated in many third-party Thunderbolt 3 eGfx docks and so users may
experience certain unexpected compatibility issues
They are basically telling you to buy a Dell or Alienware external graphics dock or you're going to have problems, but the support for external GPU is built in.

How can you tell if your usb c is thunderbolt 3 compatible?

The Dell 7577 supports Thunderbolt 3.
