*ความตั้งใจเริ่มแรกของ YAMAHA คือเพื่อรองรับการทำงานของ QMS (Quick Media Switching) สำหรับรุ่น HDMI 2.1 ต่อมา YAMAHA ก็ได้ค้นพบว่ารุ่นต่างๆ เหล่านี้ไม่สามารถอัพเดทให้รองรับ QMS ผ่านเฟิร์มแวร์ได้ เนื่องจากข้อจำกัดของฮาร์ดแวร์ที่ไม่คาดคิดมาก่อนอันเกิดจากการเปลี่ยนแปลงข้อมูลจำเพาะของ QMS ใน HDMI 2.1a ข้อจำกัดของฮาร์ดแวร์นี้ส่งผลกระทบต่อตัวรับสัญญาณ AV ปัจจุบัน รวมถึง Yamaha ด้วย (ข้อมูลที่มีการแก้ไขในเดือนพฤษภาคม 2023)
