MStar ISP Utility is a powerful, unofficial software application used for low-level communication with devices that contain MStar or MTK chips, which are very common in LCD/LED televisions, monitors, projectors, and some automotive displays. The "ISP" stands for "In-System Programming", meaning the chip can be programmed while it's still soldered onto the main circuit board.
