Confirmed with
- Notebook (generic)
On macOS, dual monitors always mirror the same content (4K@60Hz single display, or 4K@30Hz mirrored on both HDMI ports). On Windows with DP 1.2 (Intel 10th gen or earlier), dual displays cap at 1080p@60Hz; with DP 1.4 (Intel 11th gen or later), dual displays reach 2K@60Hz.
- Steam Deck
Stable enough on Steam Deck that the community has designed 3D-printable dock stands specifically for this hub. Its DP Alt Mode handling supports high refresh rates, though the firmware sometimes hard-caps ultrawide monitors at 100Hz instead of the advertised 144Hz.
