Modular Large-Screen Portable Gaming Rig Mount/Kit

The user built a custom setup for portable PC gaming because existing solutions (like extending controller grips for small screens or all-in-one handhelds) didn't meet their need for a large screen (16-inch) and full desktop PC performance. This indicates a market gap for a modular, adjustable mounting solution that can securely hold a portable monitor (15-17 inches) and integrate detachable, standard joycon-style controllers. A product could be a universal frame with rails for controllers, possibly including integrated cable management or a hub for power/video, allowing users to leverage their powerful home PCs via remote play while enjoying a large portable screen.
