Firmware archive for a monitor identified only as PA248, which matches the model code ASUS used for a ProArt display, although the name gives no brand. The 506 KB RAR likely contains the scaler board firmware or an EEPROM dump. Monitor firmware is typically written to a small SPI flash or 24-series EEPROM with a programmer to fix a blank screen, boot loop or lost settings. Confirm the scaler chip and the size of the flash chip before writing, and read the existing contents first.
