Can you please run ./msigd --debug --info --query > out.txt and upload out.txt here? I need the file to get the exact character code for s140.
Thanks a lot!

[wpisarski]

Here: out.txt

[couriersud]

Ok, great, the string representation is "\x30\x30\x85". Hex 85 is not a valid UTF8 character :-(
Need to change the code to use a hex dump.

[couriersud]

I added support for the monitor in this branch:
https://github.com/couriersud/msigd/tree/43-mag274qrx-support

You will not be able to modify monitor settings. We first need to ensure that ./msigd --debug --info --query works.

[wpisarski]

Sorry for the late reply, I was away from my monitor. I'm attaching output from that branch:
out_branch.txt
There are also errors on stderr:

Try 'msigd --help' for more information.
msigd: Error querying device on navi_down - got '5b00970008'
Try 'msigd --help' for more information.
msigd: Error querying device on navi_left - got '5b00960004'
Try 'msigd --help' for more information.
msigd: Error querying device on navi_right - got '5b00970008'
Try 'msigd --help' for more information.```

[couriersud]

Thanks a lot!
on stderr I am missing a line like
msigd: Error querying device on navi_up ...
Can you please confirm you get this line?

[wpisarski]

It's there, I forgot that triple backtick reads the first line as language tag here on GitHub and eats it.

msigd: Error querying device on navi_up - got '5b00960004'
Try 'msigd --help' for more information.
msigd: Error querying device on navi_down - got '5b00970008'
Try 'msigd --help' for more information.

I finally managed to get a WIN10 VM up and running. That caused the delay coming back to this issue.
Are you able to control your monitor settings with one of the MSI apps:

• Gaming Intelligence
• An MSI center module
• DisplayKit

Gaming Intelligence does not seem to suport the MD272QP. DisplayKit seems to support most settings based on a string analysis, but I am not able to locate the codes (e.g. 5800500 for input source). In addition DisplayKit does not support my monitor. So it's pretty difficult to get indications which codes are used by the currently unsupported settings.

In the mean time I propose I release the code without support for Navi button and audio volume. Would this be acceptable to you?

[wpisarski]

Sorry for the late reply, I somehow missed this.

This would be acceptable. I only have a heavily locked-down work Win10 laptop, but I can try setting up a Win10 box on my end and check.
