Vive Pro 2 & RTX 4090 - No ULTRA or EXTREME ?!?

[Em0Abstracts]

I am a new user to the VP2 and so far, I've been beating my head against the wall trying to figure out what is going on here.  As indicated in the post title, I have the Vive Pro 2 running on an ASUS Nvidia Gefore RTX 4090 GPU (ASUS part # TUFRTX4090O24GM) and Intel i9 14900K proc with 48GB DDR5-8000 RAM, all running Windows 11.  My system should be fully and completely capable of powering this headset even at its highest settings, but for some reason it can't.  No matter what I do, the Ultra and Extreme settings remain grayed out in my Vive Console software with the message: "Full resolution not supported by your current hardware."  That's a load of crap, because my hardware can certainly support it.  Something is obviously making the Vive Console think my GPU or other hardware can't support this, but I haven't been able to determine what it is.

So far, I've deleted and reinstalled all the Steam-related and HTC-related software and drivers multiple times using CCleaner, power cycled all the VR hardware equipment and the PC multiple times throughout that process, set the native resolution in SteamVR to 100% instead of the default 150%, enabled developer betas on both Steam and Vive Console applications, unplugged my second monitor from my GPU so that now only my primary monitor is connected to HDMI 2.1 and the VIVE is connected to DisplayPort 1.4.  I've done a reset of all the system USB drivers.  The only thing I haven't done is blown away and reinstalled the GPU drivers themselves.

Does anyone have any guidance or experience for this at all?
