Newish to Linux, need help with RDP on Pop OS

Title: Troubleshooting multi-monitor support for RDP on Linux

I am currently trying to transition my workflow to Linux while keeping my work tasks isolated on my dedicated work machine. My primary blocker is configuring remote desktop access that correctly handles my specific monitor setup: two 24-inch 1080p monitors in portrait orientation flanking a central 42-inch 4K monitor.

Everything works perfectly natively in Linux, but every RDP or remote desktop client I have tried fails to span across all three monitors or map them correctly in full-screen mode. I have already exhausted the common solutions suggested by AI, so I am looking for a more robust, "bulletproof" recommendation for software or configuration settings.

Alternatively, if a reliable remote desktop solution for this layout doesn't exist, I am open to suggestions for running a compartmentalized instance (VM or otherwise) that allows me to switch seamlessly between my Linux desktop and the work environment.

My hardware specs are: Intel i7-12700KF, 48GB RAM, and an NVIDIA RTX 2080 Super (8GB). Any advice or pointers toward tools that handle non-standard monitor arrays effectively would be greatly appreciated.
