Firmware dump for the Acer X223HQ LCD monitor in a RAR archive of roughly 100 KB. The name gives only the model, with no main board code, scaler or chip details, so check the board and match the image to the actual memory chip before relying on it. Technicians write these dumps to the scaler flash or settings EEPROM to cure no-picture faults, power-button lockups and corrupted menus. Use a suitable programmer and always read and store the original chip contents first, since board revisions may differ.
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.
