the steps test files? they raise lift gradually, you should see a major change, especially over 2600.

Any file in that folder shows a difference on my C2, but of course, the effect is always more evident with a 4000nits RPU.
Yeah the steps test files. I dont see any changes at all. Meanwhile, the L5 test file below shows that the command worked. Something is wrong.

the steps raise positive lift gradually so it is normal if you don't notice change until it reach 2600+

if it was going from 2048(0) to 2100, you would see a slight change but in the test file, it goes from 2048 to 2055 to 2065 to 2075 to 2085 to 2095 to 2100 etc so you don't really notice the difference between 2095 and 2100. If you don't see it changing after 3079, then there is a problem

Yeah no change at all. Are my dolby vision settings below correct? When I first updated to this cpm build, I noticed dolby vision was disabled by default. The settings also look different compared to CE build.

Just update to cpm build then put this command in via putty right? No other steps?

nano /storage/.config/autostart.sh

(
echo Y > /sys/module/amdolby_vision/parameters/dolby_vision_keep_source_meta_level_5
)&

not sure how it's possible if L5 works...
I'm using CPM's compiled build(private) while you're using the build(public) compiled by someone else so maybe he did something wrong, I don't know.
Everything works on my end. Try A13

Just tried A13. Still the same. No change in brightness.

Sony A95L.
The internal media player app is absolute garbage. It takes forever to load the folders in my 4TB hdd. Maybe I will copy the video file to a small usb and see if it can load the file faster.

OK just tested the file using internal player app and the brightness doesn't change either. Damn so positive lift won't work on my tv?

Will test the LG C9 next.

deadchip, you sure, you saved your autostart.sh file correctly? Check via SMB in folder "configfiles", if your file "autostart.sh" only contains the last three lines (and not!! the nano ... line).

Ok then it looks like your TV internal target is higher than 1000nits and it's ignoring the trims which is surprising since @powdeau confirmed not a long time ago that the trims were working on his G4.
I assume the G4 also have a target higher than 1000nits or maybe he didn't test the right file or the Sony just works differently than LG so lets try something:

tell me if the trims work on these files

Test 1 (1000nits MDL + L1 under 1000nits : https://drive.google.com/file/d/1sIYgFh ... drive_link
Test 2 (1000nits MDL + L1 over 1000nits : https://drive.google.com/file/d/11Ih1SN ... drive_link

I only played the first three minutes but I saw the brightness change in both files. Should I play the whole video?
