Thank you for your reply.
Ok, let's proceed slowly to see if you can understand me.
The LT27A300 is, in fact and in itself, a computer which is driven by an ARM cpu. This computer (inside the monitor), runs an operating system which is Linux. I can see this by placing a serial terminal on the "Service" connector, unlocking the "Top Debug Menu" and, from there execute a shell.
So, by using Linux, the manufacturer is obliged by the GPL license to disclose the source of the software, or proving that it is proprietary.
So, that's what I'm asking for, the opensource of the software that drives this monitor.
I hope I have made myself clear.
