Are all the owners in this thread satisfied with the brightness of this set ??
I watch in a darkened room with a self-calibrated screen, and I'll say that I've never had a TV that needed to be turned up past 50% brightness (usually less), including my 2016 M55-D0. Demo mode in stores is the worst possible way to evaluate a TV.
Obviously, with HDR content, peak brightness matters. How much it matters depends on how much of your viewing is HDR content. With SDR content, in dimmed rooms, I think most TVs are sufficiently bright. And in stores, where all those TVs are probably not being fed HDR content anyway, choosing based on torch-mode performance seems like a poor choice, IMO.
I think it's clear from the rtings.com reviews (compare the 2016 and 2017 M Series side-by-side with the P-Series as a benchmark) that the 2017 M-series has improved HDR performance at the cost of somewhat reduced SDR performance. For me, since 95% of my viewing is still SDR, and since the 2016's HDR performance is IMO still at least acceptable, I think it's a better choice, overall. If you want a Vizio that improves both SDR and HDR performance over the 2016 M-Series, you'd need to go to the P-Series.
