Is it plausible to write more than 256 in Linux?Microsoft doesn't have any APIs for EDID reading/writing. I'm using NVIDIA's NVAPI and AMD's ADL SDK to communicate with the display. Setting the segment pointer and reading/writing must happen in the same transaction with a repeated start, but NVIDIA and AMD don't provide a way to do a repeated start, so it can only access the first 256-byte segment. The segment pointer resets after every stop, so I can't split the transactions. It might be possible to do this in Linux, but I don't know if there are any tools that can. I was planning to release the source code with the final version, but I've uploaded the beta source code for you here: https://www.monitortests.com/download/ED...ta-src.zip |
