I bought this Sabrent USB Type-C to HDMI 2.1 Adapter: https://www.amazon.ca/gp/product/B08Y246V8X
I'm using it with a Dell XPS 15, which has the following ports according to the Dell website:
However, when I connect this adapter to my laptop, either in the USB 3.2 port or in one of the Thunderbolt 4 ports, I always get this error:
What does this mean? My first guess was that the adapter requires a DisplayPort version that is higher than what the XPS 15 provides over its USB-C outputs. The problem is that neither the adapter nor the XPS 15 say anything about which specific DisplayPort version they are using.
However, to my understanding, Thunderbolt 4 supports DisplayPort 2.0, so that is the version the XPS 15 should output. And since that's the latest DisplayPort version, the Sabrent adapter cannot possibly require any newer version.
I tested this on a Samsung Odyssey Neo G9 which has an HDMI 2.1 input and is capable of 5120x1440 at 240 Hz with 10-bit color. This adapter, whether connected to the USB 3.2 Gen 2 or Thunderbolt 4 ports, can only achieve 3840x1080 at 60 Hz with 8-bit color. This is much less than either DisplayPort 1.4 or HDMI 2.1 are supposed to be capable of.
So what does this error mean? Is there any setting I need to change or driver I need to install to fix this? Should I just return this adapter and buy a different one instead?
