LOGITECH GAMING SOFTWARE
As always you will need to download the latest drivers/software from the official Logitech support page.
With that out of the way if your keyboard features a previous firmware version the software will update it after asking you as seen above.
The home window shows you a picture of the keyboard and thus from here you can choose what to "tweak" next.
From the first tab you can either program the G-Keys manually or use one of the ready profiles it may (or may not) have for compatible games detected in your system (after that you can save your settings for use later on).
Remember the game mode key? Well the software also allows you to pick which keys you want disabled when that mode is on, just click on the keys and that's it.
Leaving out the RGB illumination there are three lighting modes available with the G910, freestyle, zones and effects. Freestyle allows the end user to select individual keys to illuminate as seen above.
You can configure specific zones on the keyboard which you can then illuminate again with the colors you want.
As for effects these include color wave, color cycle, breathing, star effect and key press but perhaps the most impressive feature is the fact that you can change both their direction (horizontal/vertical) and speed.
This is not the first time we've seen the key press heat map but although i don't consider this to be important i hear that it can be really useful for people who are looking for ways to improve their typing.
