Hi George, This dongle is from Amazon and is described as the "MysRuida USB Type C to HDMI 2.1 EMI/RFI Braided Cable 0.6ft, 48Gbps, 8K@60Hz/4K@144Hz/2K@240Hz, HDCP2.3/Dynamic HDR/eARC/VRR/ALLM/DSC1.2/Dolby Atmos/DTS, DP Alt Mode Compatible with PS5 Xbox Monitor"
Just FYI, these CH7218 USB-C to HDMI 2.1 adapters seem hard to come by, hence why I purchased this specific one. I’d note that the Volans brand one, despite claiming to be CH7218A, is not. Mine was VMM7100. I suspect the Lindy 43428 may actually be CH7218-based, but I have not tested that one personally. The one I tested exposes: branch_dev_id: 0x2b02f0 branch_dev_name: CH7218 Thanks, Stephen On Thu, Jun 25, 2026 at 2:38 PM George Zhang <[email protected]> wrote: > Hi Stephen, thank you for the patch. > > What dongle you are observing this issue on?
