    How ? I2C Programming of RTS5450 and RTS5441

    I'm new to I2C programming, and I need to find out / learn how to program R/W RTS5450 and RTS5441.
    What hardware and software do I need?

    I am in the same situation. I need to program a RTS5450M for a BenQ SW271C-B monitor. Does anyone have any information on this? Thanks.

            I was finally able to easily read and write an RTS5450M!!!
            I purchased an Alexsof RTS5450M configuration board and my SVOD4 programmer, but it's compatible with other programmers.

            You can find that board here: https://alexsof.com/product/rts545x-...ller-firmware/

            Be sure to check out the website because there are other resources, such as the MPS phase controller programmer or the DDR4 test, that are super interesting.

                  I also have the XGecu T48. I'm not really an expert on this, but it seems the RTS545x uses I2C/SMBUS, and the XGecu has some limitations in this regard.

                        I'm attaching the file for the RTS5450M used in the Lenovo P24H-2L LCD monitors in case it's useful to any colleagues. https://www.badcaps.net/forum/troubl...-rts5450m-dump

                        As I recover dumps, I'll upload them. I'm still planning to extract the one from a 1,600€ BenQ monitor...
