Screen projection over 5 GHz wifi?

[jazzymotorcycle]

Hello,

I'm trying to project my screen from a computer to the Spectre x360 to use as a second display. However, I can only find the computer when it connects to my network via 2.4 GHz but not via 5 GHz.

Doing a little digging, when connected via 2.4 GHz, the Spectre outputs a new SSID with the laptop's name on the same 2.4 GHz channel (starting "DIRECT-..."), which I presume my computer uses to make the initial connection to the Spectre. It does not output this when connected via 5 GHz, and I therefore cannot find it from the computer. Unfortunately, the 2.4 GHz frequency is crowded where I live, which I suspect is the cause of frequent disconnections, so I would like to use the 5 GHz band for this.

I have an HP tablet (Pavilion x2 10-n100na) that allows projection on the 5GHz band: while connected via 5 GHz, opening the Connect app produces an SSID with the tablet's name in the 2.4 GHz band. I am able to project to the tablet, and projection happens over 5 GHz (I've verified this by viewing traffic going through the router). However, the tablet is small and has a lower resolution, making it unsuitable for a second screen for work.

I was wondering if there was a setting that I've overlooked in order to make the Spectre behave like the tablet? Specifically, to make it output an SSID on the 2.4 GHz band while still connected to my network on the 5 GHz band. I've tried both the latest drivers provided by Windows, as well as uninstalling the wifi driver and installing the latest wifi driver on the HP website. Is there anything else I can try?

Thank you.
