Keeping the Edge: Samsung Odyssey G40B Driver & Firmware Update Guide
Whether you're pushing for rank in a fast-paced shooter or enjoying an immersive RPG, the Samsung Odyssey G4 (G40B) is built to keep up with its blistering 240Hz refresh rate and 1ms (GtG) response time.

This guide will walk you through the simple process of updating your drivers and firmware to maintain peak performance. Why Update Your G40B?

To get started, you need the correct files from the Samsung Support Download Center.
Identify Your Model: Check the back of your monitor for the model code (e.g., LS25BG402 or LS27BG400).
Locate Downloads: Search for your model on the Samsung site. You will typically find two main files:
Device Driver (Windows): Helps your OS correctly identify the monitor's specific capabilities. | Component | Update Frequency | Benefit |
Upgrade File (USB type): The latest firmware (e.g., version 1006.0) to update the monitor’s internal software. Step 2: Installing the Windows Driver
If your PC identifies the monitor as a "Generic PnP Monitor," installing the official driver can unlock specific color profiles.
Download the Device(Install) executable from the Samsung G40B Support Page. Run the .exe file and follow the on-screen prompts.
Once finished, the monitor should be recognized by its full name in your Display Settings. Step 3: Updating Firmware via USB

Pro Tip: If the specific model page is hard to find, the driver for the G40A often shares architecture with the G40B, but always try to grab the specific G40B file first.
The G40B does not ship with a factory ICC profile. Users often mistake ICC profiles for drivers.
Samsung does not provide Linux drivers. However, using edid-decode and xrandr, you can manually set 240Hz. Install read-edid and force the mode:
sudo get-edid | parse-edid
xrandr --newmode "240.00" ... (values from cvt)
xrandr --addmode DP-1 240.00
For persistent configuration, write a udev rule to load the correct EDID.
The G40B supports direct firmware updates via the USB port, but you can also do it through the OSD (On-Screen Display) if you have network connectivity, or via the Samsung Odyssey controller app if applicable.
