Small MSI archive for the G27CQ4 E2 monitor, paired with the main board code 715GD361-M0D-B00-005K. The 715G prefix is the numbering style used by TPV for its monitor electronics. At 466 KB the package most likely contains a firmware dump of the scaler flash or the EEPROM, which is used to repair a monitor with no picture, a boot loop or lost settings. Match the full board code on the PCB sticker, read and save the existing chip contents first, then program the replacement with a suitable programmer.
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 @biositechyangiyer. Enginerys does not host this file.
