Logitech MX Master DPI settings

The following is my local copy of 210000Mnn-2's answer on how to change DPI on an Mx master 3:

I had a similar problem since I wanted to know the currently set DPI value which is not available in Logitech Options, unfortunately.

Luckily, I noticed the option to backup the settings into the cloud which implies that the slider value among the other options are saved somewhere on the disk.

In %appdata%/Logishrd/LogiOptions I found a few settings files that are human-readable (XML):

At first, you need to get the UUID of the profile you are using. In the directory aforementioned, open apptable.xml in an editor with XML-support (I recommend VS Code) or in notepad.exe.

Find the profile for the application you want to look up. In my case it looks like this for CS:GO:

<profile>
  <name>csgo.exe</name>
  <id>2313a307-6976-4ab8-87d4-b0d07bed022f</id>
  <exe>csgo.exe</exe>
  <altfullpath />
  <fullpath>C:\Program Files (x86)\Steam\steamapps\common\Counter-Strike Global Offensive\csgo.exe</fullpath>
  <iconpath>C:\Program Files (x86)\Steam\steamapps\common\Counter-Strike Global Offensive\csgo.exe</iconpath>
  <iconindex>0</iconindex>
</profile>

Note the ID somewhere.

Now, go into devices/. There you should find at least one folder. If you're using more Logitech products than the MX Master 3, there might be some more folders, one for each device. I guess, the MX 3 folder is named 6b023 (which is the name on my computer). Go into it.

Open Profiles/.

Load the file which has the name of the profile's UUID you wrote down in an editor. In my case, this is 2313a307-6976-4ab8-87d4-b0d07bed022f.xml.

Press Crtl+F and search for "dpi".

You should find something like this:

<params>
  <param name="sensorCount" value="1" />
  <param cur="1150" defaultDPI="1000" minDPI="200" maxDPI="4000" stepDPI="50" name="sensor" value="0" />
</params>

The value cur="1150" should be your sensitivity in DPI.
