Archive linked to the ViewSonic VS11802, a model code ViewSonic uses for its products, but at only 906 bytes it cannot contain a usable firmware image. It is more likely a text note, a link, or a damaged or empty archive. Open it and check its contents before counting on it for any repair. Real monitor or scaler firmware is normally far larger and is written to an EEPROM or SPI chip with a programmer. Look for a full-size dump that matches the main board marking, and save the original chip before writing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
