*YAMAHA initially intended to support QMS (Quick Media Switching) within the HDMI 2.1 specification. However, YAMAHA later discovered that these models cannot be updated to support QMS via firmware. This is due to an unforeseen hardware limitation caused by QMS specification change in HDMI 2.1a. This hardware limitation affects current AV receivers, including Yamaha.
