Las diferencias son dos:
1.- En la SM9800 el Higher Picture Quality Index (lo que quiera que sea eso) es de 4000 y en la SM910 es de 3800.
2.- La SM9800 tiene Auto Low Latency Mode y la SM9010 no lo tiene.
Por lo demás, tienen exactamente las mismas especificaciones.
Buenas noches.
Sobre el Auto Low Latency Mode:
The "Auto Low Latency Mode" (ALLM) is a new HDMI feature defined in HDMI 2.1 that allows a source (e.g. an gaming console such as the XBox One S or XBox One X) to direct all compatible components in the HDMI chain (e.g. AV-Receiver and TV sets) to enter its low-latency mode automatically without requiring the user to navigate a menu to set the optimal latency for their content. This allows the picture to be displayed with least possible delay which is espcially important for gaming.
