Firmware image for an AOC 931Sn LCD monitor, with the name also citing TFT185W80PS, which looks like the 18.5-inch panel the build was paired with. The 256 KB binary is typically written to the scaler board's SPI flash with a programmer such as a CH341A. Reflashing it can cure a dead OSD, boot loops or wrong-resolution faults after flash corruption. Read and save the original chip contents first, and check that the panel model and chip capacity match, as a firmware built for another panel can leave a blank or garbled screen.
