Firmware for the BenQ EW2440-B monitor, built for a Realtek scaler with an external SPI flash and marked for ISP programming, packed in a 202 KB RAR archive. RTD is the name Realtek uses for its display controller chips. A technician uses the file to revive a monitor with corrupted firmware, symptoms such as no backlight, no OSD or a power LED blinking without a picture. Flash it with an ISP tool or an SPI programmer, keeping a backup of the original chip and confirming that the board matches.
