  "account": "The SM750 (Silicon Motion GPU) HDMI Driver is an open-source Linux display driver for the SE-DP750A-HDMI PCIe card. This experimental driver allows for optional modes that exceed published GPU or monitor clock limits, potentially resulting in no signal, distortion, or an unstable display. Users should maintain SSH access or another recovery route when attempting non-EDID modes. The driver is compatible with Ubuntu 24.04 and Linux Mint 22, and can be built locally using DKMS. It requires Linux 6.17 or newer, and supports resolution up to 2048 pixels wide, with higher resolutions requiring a 2560x1080 ultrawide monitor with FULL WIDESCREEN STRETCH ENABLED. The driver employs dithered RGB565 colour conversion and update optimizations for smoother performance. Building the driver locally is recommended, as prebuilt packages are not always available.",
