Tips for Updating Samsung Odyssey G9 Firmware
The exe file that comes from Samsung is compressed with ALZip, which is available from the Windows Store. You can open the file for self-extraction or use that application to decompress the IMG file within. Copy the file to the root directory of a FAT32 (surprisingly NTFS also worked for me) USB stick.
Unplug the USB Type B plug from the rear of the monitor if it is attached. Then attach the USB stick to the outermost port on the rear. If you plug into the innermost port it will not update.
Go to the front of the monitor and use the OSD stick to go the the Menu. Choose Support -> Software Update. If you followed the steps correctly the stick will start flashing as it is read. If it does not read it may be you forgot to unplug the USB Type B which causes the monitor to become a hub, stick may be in the wrong USB port, or file is not in root directory.
Update should take less than 5 minutes. A progress bar is displayed.
