Dolby Atmos Compatibility

[Atmos]

Hi guys

I have a Q9FN TV and planning on getting the Q90R soundbar. I have some questions regarding it. Would appreciate some input

1) according to a Samsung Customer Care dude, Samsung TVs are not Dolby Atmos compatible. Meaning, if connected to a soundbar (eg. Q90R soundbar), the TV apps won't transmit Atmos to the soundbar. True?

If not true, then my next question is:

2) Dolby Atmos and DTS-X require eARC and HDMI 2.1 to function. (This is according online techies) True? If so, how do the current TVs (Q900r excluded) transmit these formats?

3) if the above questions are true, what's the best way to get the best out of my TV and Soundbar?

Thanks guys

Ps. My name is not Atmos, I mistakenly typed in the topic in my username slot and can't undo it.

Did you figure a solution?

There's a problem. The implementation of eARC available in all the 2019/2020/2021 Samsung TVs is broken. You can't send uncompressed 5.1 or 7.1 audio even if eARC and passthrough is enabled on the TV. Basically LPCM passthrough through eARC doesn't work.

Samsung doesn't acknowledge this, so don't expect a fix anytime soon.
