Hi! That is indeed interesting, and could be related to local dimming. We’ve flagged it to our testers, so stay tuned!

Awesome!

Interesting that this has better color volume than the q7. Is it noticeable in real usage? Could it be due to local dimming?

Basically it would be the same as the 100% window values accross all window sizes, as local dimming only works to improve brightness in different dimming zones by concentrating power to zones instead of the entire LED array. Which is why you will typically see the brightness levels increase as the zone size decreases when local dimming is enabled. Until it reaches a zone limit where the window size is smaller than the zone size capable with the allowcated zone count. Which is where you see the brightness decrease around 10% - 20% window size as there are not enough zones to accomodate the small window area. Basically local dimming off would show 565cd/m2 accross all windows for the QM7.

Yes I see what you mean w/o local dimming but I still wonder if the local dimming algorithm still has some part to play in small highlights being intentionally dimmer. On a tv with considerably less dimming zones, the x90l, the small windows considerably exceed the 100% brightness window. This leads me to believe the relatively low highlight brightness on the q7 is due to more than just not having enough zones. I guess there isn’t really a way to test this but. Still food for thought.

It would be interesting to see how HDR brightness scores with local dimming disabled. I’ve noticed with mine that small highlights are severely darkened with local dimming on (presumably to prevent blooming). This would explain the large dip in brightness for small windows.

Can’t wait for this review! On the fence between the latest 6 series and this, but there haven’t been any good reviews yet
