Firmware dump from a Microlab GWT M1931 monitor, read from the external SPI flash of an MStar scaler, as the MST EXT SPI and ISP tokens indicate. The timestamp shows the read was taken on 2025-05-11, and the RAR file is just 47.4 KB. ISP means in-system programming, so the image may have been read through the monitor's service port. Use it to reflash a display with corrupted firmware, no backlight or boot loops. Save the existing chip contents and check the image size against the chip before writing.
