Unable to set certain values

[SZanlongo]

I'm trying to toggle PBP on my monitor, and apparently unable to set the value to turn off PBP.

I have determined:

• PBP address="0xe9"
• "Off" value="0x00"
• PbP 50% value="0x24"

These were confirmed by using: ./betterdisplaycli get -name="DELL U3425WE" -feature=ddc -vcp=0xe9 after manually switching between the different modes.

I am able to start a 50% PBP via: ./betterdisplaycli set -name="DELL U3425WE" -feature=ddc -vcp=0xe9 -value=0x24.
However, my attempt to turn off PBP via: ./betterdisplaycli set -name="DELL U3425WE" -feature=ddc -vcp=0xe9 -value=0x00 fails. I don't get any message, but PBP persists, and is confirmed by running ./betterdisplaycli get -name="DELL U3425WE" -feature=ddc -vcp=0xe9 which returns the PBP value of 36.

Any ideas as to why the set operation doesn't seem to work?

I tried the m1ddc tool, and was able to use ./m1ddc set pbp 0 to turn off PBP, so I'm unsure what I might be doing wrong with the betterdisplaycli command.

Interesting. I will take a look into it - I don't see why the command should fail but there might be some kind of parsing issue maybe.

Does simply betterdisplaycli set -n=dell -ddc=0 -vcp=0xe9 work? What happens if you create a custom command controls in the app and associate buttons for it under Hardware Control to configure PBP? Does that work?

Anyway, I created an issue so I can look into it. #4252

Fixed.

Fyi: an updated internal pre-release is available with the fix.

Thanks!
