ZIP archive, 5.25 MB, for the W2042S monitor, as the name indicates, with no version, scaler or board details given. The size suggests the package holds more than a single small flash image, perhaps several firmware versions, tools or documents, so unpack it and review the contents first. Monitor firmware is normally written to the SPI flash beside the scaler with a programmer to fix boot or picture faults. Match the main board and chip, and keep a backup of the original dump.
