The key innovation is treating every pixel as its own independent update region rather than using a global update timer, eliminating the traditional trade-off between refresh rate and contrast. This requires 540 MB/s memory bandwidth (vs. 20 MB/s for traditional controllers), DDR3 memory, and DisplayPort. The project involved 20+ PCB revisions, switching panel suppliers mid-development, fighting uncooperative chip vendors for driver source code, and implementing dithering algorithms, touchscreen support, and a hybrid grayscale mode. The final product is open source — hardware designs, FPGA gateways, and firmware all publicly available. ## Full article daily.dev links to this article rather than hosting it.
