Firmware archive for an LG monitor model M1717A-BTH, labelled PQ and version V2.01 in the name. The small 219 KB RAR likely holds the scaler flash image used to recover a monitor that stays dark, blinks its power LED or has a corrupted menu. Scaler firmware is usually written to a small SPI chip with a programmer, or through the service port. Confirm the main board and panel match the M1717A family, and dump the existing chip before writing so you keep a working copy to fall back on.
