Hi Blondie, Q70 to Q80
When stepping up from the Q70T and Q80T you gain a lot of new features. For example:
• Full Array backlighting system which precisely controls the backlight system and intelligently adjusts and improves contrast for deeper blacks and brighter whites
• Ultra Viewing Angle – a new panel design which provides a vibrant picture to any seat in the house, even during daytime hours or when the lights are on.
• Object Tracking Sound (OTS)- OTS is an AI Sound feature that uses the additional arrangement of dedicated up-firing speakers, to experience realistic 3D sound that tracks with the motion on the screen.
Thanks, ^Scott
