Question is for all that have a 77, is 42 inches off the floor too high? It would be a pain in the ass to move as I'd have to put another piece of wood up but if it's going to be terrible I'll do what I gotta do.

Due to room constraints I am unable to lower it any further. I am 13' back from the TV so a few feet farther than you. My mount is an articulating wall mount.
IMO and from my experience with my current setup I think your viewing at 10' would be a little more comfortable if you lowered it a bit. But if you are not OCD and can tolerate misaligned objects then you just might get used to it at 42". I would lower mine probably about 3" if I was able to. I have a couple of friends that mounted their TVs above a fireplace and those are crazy high.
IIRC I think the optimal viewing height is for your eyes to be about the midpoint of the Panel when at your viewing position. If I followed this guideline then my TV is actually mounted 8" too high. But it is fine for me where its at.
Yes, above a fireplace is ludicrous, and will give you neck pains and back pains down the line.
I used to think that the middle of the screen should be at eye-level. Also for PC monitors at a desk in an office, I've seen guides that say your eyes should be level with 1/3rd of the way down. I'm sure that's correct for PCs at a desk but I fell into the trap of thinking it's correct for TVs in a house.
Happily recently someone posted this image, which I am accepting as "correct" for every screen size
This is great because the distance you sit from the screen has no bearing on what height it should be. It's all about the height of your head when you are sat down. Keeps it so much simpler!

Do you even realize how insanely dark 0.0003 nits is? Because that's what the target for limited range 17 is when using gamma 2.4 and 120 nits peak. That's like 1/100 the brightness of a 3% slide which already is very very dark.
In the past I was also always trying to get 17 to show up on those flashing bars test pattern but all this has gotten me was often seeing elevated blacks in movies...
I wouldn't be surprised if most people have their <1% way too bright.
I think the best way to test if it's crushed or not is to look at a 0.5% (17) and 1% (18) fullscreen pattern in a pitch dark room. There should only be some faint glow.
I agree, and after reading the same recently I now have the make a mental note not to use those black clipping patterns. Your eyes cannot adjust correctly to see 17 when it's "correct", if there is other brighter content on the screen at the same time. Those black clipping patterns are therefore dangerously misleading
if you think you need to adjust so that you can even "just see" 17, on those patterns, which is the bad advice
I've read for many years in many guides, including the AVS709 one! ("Set black level to lowest setting where 17-25 flash", it says - NO
! If you can see 17 on this pattern, it's too bright!)
