BT.1886 for Night and Day or 2.2 for Day
 
Hello, I have a Vizio PQ LED. My black level with Local Dimming Off is around .029. With that being said I usually keep my Living Room lit. Would it be better to use BT.1886 or 2.2 for my living room. I am able to Calibrate my display and have an i1 Display Pro and all of that. With BT.1886 that would make my 5% Black around a gamma of 2.0 and the higher end around 2.3. Obviously 2.2 would be flat across the board. Would love some insight on this, thanks everyone.

bt.1886 is supposed to create a more theater like experience. With an infinite contrast ratio bt.1886 becomes a flat 2.4. On my PQ I use 2.1 for calibrated lighted room viewing, but leave it at 2.2 for dark room viewing. I targeted bt.1886 for calibration.

So you Calibrate 2.2 setting to BT.1886 and then during the day switch it to 2.1? If I did that then my Gamma at 5% would be at 1.9 or so which seems really light. BT.1886 in this case (with LD Off) gives me even more lifted blacks than Power 2.2, which is why I was wondering if BT.1886 shouldn’t be used for a brighter room also. I do understand that on an OLED or absolute 0 you will get a straight 2.4 which definitely is quite a bit different (and an obvious dark room setting) then these displays at BT.1886.

That is normal. Daytime or bright room viewing needs a lower gamma setting for the low end or else dark scene detail will not be visible.
