Software & Lighting
Being that this is a Corsair gaming keyboard you can use the Corsair CUE software to customize it, although it is not required. The keyboard will work just fine without the CUE software, but if you want to create any macros, actions, etc you are going to want to use CUE. When you load up CUE and select the K63 Wireless it will show you an overview of the keyboard. With three main tabs on the left side. One gripe I have with CUE and wireless products is that the battery level is not shown on this screen. We are on the main screen for the product, so it would be nice to see how much battery we have left.
If you click on the actions tab here you can reprogram the keyboard, you have the ability to reprogram each key to a macro, text, a different key, media controls, launch an application, a timer, disable the key, or set it to switch to a different profile.
Lighting effects are a little limited as we only have blue LEDs, but you have the ability to switch between different shades of blue. You also have different effects like visor, rain, pulse, wave, type lighting (key), type lighting (ripple), and just static.
Under performance you have a few options to either turn on or off they include disable Alt + Tab, disable Alt + F4, disable Shift + Tab, Disable Windows key, and Disable wireless encryption.
In the global settings you have the settings for all of your connected devices. For the K63 we can see the battery level (although it could be represented a lot better on the main K63 page), the polling rate, brightness (which really should be in the lighting section), keyboard layout, and change LED color. You are given the option between blue and ice blue, you cannot tell the difference.
The backlighting on the keyboard is just blue. Corsair has added the blue top plate to make the illumination look better and it actually does a good job.
