I loved your testing of eARC and soundbars last year (https://www.rtings.com/soundbar/learn/research/1-3-tbu-article), but I am wondering if you would consider adding a test of eARC latency to your TV test bench, especially when sending an Atmos or DTS:X signal. The linked test all compared soundbars using a single TV. You would think that eARC would be the same between TVs, but my testing is telling me it isn’t.

As an example, I am currently comparing my new Samsung S90D to my LG C1, and there is consistently about 67ms more lag when passing Atmos to my Samsung Q990D via eARC, whether I set the TV to Pass-through or PCM. 67ms is not a lot on its own, but it takes the total Atmos delay from acceptable to noticable, and a bit deal breaking for gaming. I would love to have this info when considering which TV to buy, as eARC is pretty much the only way to go if you want to use all the gaming bells and whistles of the newest TVs. I can throw together a video of the S90D-C1 comparison if there is interest.
