Firmware archive for an AOC 2236vwa LCD monitor, about 67 KB in size. Files of this small capacity for monitors are usually the contents of the scaler board EEPROM or small SPI flash, used to restore a unit with no picture, a stuck logo, wrong menu or settings lost. The dump is typically written with a programmer such as a CH341A-type tool after desoldering or clipping onto the chip. Confirm the main board and scaler chip in your monitor match, read and keep the original data first, and check that the image size equals the chip capacity.
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.
