OREI UHD 404 4x4 HDMI Matrix (Sponsored)

The OREI UHD 404 is the option I point to when your setup needs real routing control—multiple sources and multiple displays, independently. In my testing it handled mixed 4K and 1080p displays smoothly with smart downscaling and solid EDID/HDCP negotiation, so the system stays stable instead of acting flaky.

Pros

+4x4 routing: any input to any output (or mirror one source to all)
+Smart downscaling for mixed 4K/1080p displays
+Stable HDCP/EDID handling for consistent picture and audio
+Supports HDR10, HDR10+, and Dolby Vision
+IR remote for quick control

Cons

-Overkill if you only need one display or simple mirroring
-More setup complexity than a basic switch or splitter
