How to translate device screen position to sendevent position?

[C C7]

I know about the input tap x y shell command, however, I'm trying to understand how to
perform a click using the sendevent command. I been able to achieve it with the following command:

sendevent /dev/input/event5 3 53 X &&
sendevent /dev/input/event5 3 54 Y &&
sendevent /dev/input/event5 0 2 0 &&
sendevent /dev/input/event5 0 0 0 &&
sendevent /dev/input/event5 0 2 0 &&
sendevent /dev/input/event5 0 0 0

Where `X` and `Y` is the position that will be clicked, I'm testing it on the android emulator `BlueStacks 5` which the Display Resolution set to `1920x1080`.

The code is working and the click is fired, however, I couldn't understand how to convert the position where I want to be clicked to the sendevent XY position.

If I send using ADB:

sendevent /dev/input/event5 3 53 2000 &&
sendevent /dev/input/event5 3 54 2000 &&
sendevent /dev/input/event5 0 2 0 &&
sendevent /dev/input/event5 0 0 0 &&
sendevent /dev/input/event5 0 2 0 &&
sendevent /dev/input/event5 0 0 0

It clicks somewhere around x75 y75, how this calc is done? i mean screen xy -> sendevent xy?

------------------------------------------------------------

How to replicate:
-----------------

* First enable BlueStacks 5 adb in the window: `Settings -> Advanced -> Android debug bridge`
* Open a cmd window and run `cd C:\Program Files\BlueStacks_nxt` assuming BlueStacks where installed in the default path.

Execute the commands:

* `hd-adb connect 127.0.0.1:X` where X is the port shown in the window where you enabled the ADB.
* `hd-adb -s 127.0.0.1:X shell`

Now we are on the shell, execute a new command: `getevent -p`
and search for:

... /dev/input/event5
  name:     "BlueStacks Virtual Touch"

On my emulator the input event for touch is `event5` on yours it can be different, replace it according.

Now you can simulate a click with the code below changing `XY` to the position where you want to be clicked:

sendevent /dev/input/event5 3 53 X &&
sendevent /dev/input/event5 3 54 Y &&
sendevent /dev/input/event5 0 2 0 &&
sendevent /dev/input/event5 0 0 0 &&
sendevent /dev/input/event5 0 2 0 &&
sendevent /dev/input/event5 0 0 0

I'm trying to figure out how to convert the emulator screen position to the `sendevent` position.

For example, if you want to perform a click at x200 y200, using sendevent what the value needed?

How to calculate it?
