Yeah they should of just push the updates out at the same time.
But Jesus just gives us the QLED Q90R EArc update already.
Somewhat of a good sign. Knowing the soundbar got the update
I purchased the Q70R TV and the matching Q70r soundbar for the sole purpose of Dolby Atmos. I want Dolby Atmos sound from my Xbox One X without connecting it directly to the soundbar (I lose game mode and variable refresh rate if not plugged into the TV). The only way to do this is with eARC. The Q70R soundbar got the firmware update for eARC but the Q70r tv did not. Samsung please update the firmware on the Q70R tv!
This is how I have it set up. But the TV does not detect the Xbox One when connected to the soundbar and I have to change the input on the TV to soundbar and then change the input on the soundbar to HDMI. You can manually turn on Game mode but not variable refresh rate. Then there's the lipsync issues. The soundbar got the eARC update and if the TV gets it as well then most of these issues will be solved.
