HP Omen 16-N0000 - Dual USB-C Display Port - Not connected to Discrete Graphics Card

[TheSpanoMan]

Hi All,

I have a 2022 model HP Omen 16 with the Ryzen 7 6800H and the Nvidia RTX 3070ti.

I'm trying to connect two 1080p 165hz monitors via the two USB-C connections on the back of the laptop. These USB-C ports are advertised as having displayport. I'm using a USB-C to Displayport cable for both. While I do get picture and no issues I noticed that the monitors are only using the integrated AMD graphics not the discreet 3070ti. Are these USB-C not connected in any way to the Nvidia graphics? I even turned on the MUX switch and for some reason they are still using the AMD graphics card. 

This wouldn't be an issue but when playing any games while having these connected after a few minutes the frames drop to ~5 and the whole computer starts to slow and freeze up (even after exiting the game). The fans also ramp up to full. The only way to fix the slow down is to restart. 

Before anyone asks... Windows is up to date, all drivers are up to date, tried activating the ALT mode for the USB-C in the bios, HP Driver support is indicating everything including the BIOS and Firmware are all up to date. 

Thanks!

Adding with information that I found during my research.

1. The AMD Ryzen 7 model that I have doesn't have a Thunderbolt board installed. The USB-C is only Super Speed so that answers why I can't connect monitors from those connections directly to the RTX 3070ti. 

2. With the above info in mind. That is fine as I can game on the main display but the issue still arises that the computer comes to a crawl in both computing power and FPS in a game after only a couple minutes of gaming with the monitors connected. If I disconnect the monitors it works as expected and without issue. 

Does anyone out there know why it's having an issue running these monitors while gaming? I don't have anything graphic intensive on there just youtube and discord and email.
