The TKL apart from most other keyboards, though, is its on-chassis micro-screen. Beside the scroll wheel and button is a little monochrome OLED display with a resolution of 128x40. Though it may just look like dressing at first, this unusual feature makes the keyboard more customizable. By default, the OLED display shows just the SteelSeries logo and brand name, but you can upload other images (including GIF and JPG files) for the keyboard to display. (Animated images display at a rate of 10 frames per second.
You can also use the OLED display to adjust system settings (such as volume), or to switch profiles right from the keyboard display, all without having to reference a dialog or slider on your monitor. SteelSeries implements some of this via an easy-to-use onboard menu system. By pressing and holding the keyboard's clickable scroll button for a few seconds, the OLED screen will switch to display the menu, which can be navigated using the button and scroll wheel to tweak settings, work with macros, and change profiles.
SteelSeries also equips this keyboard with a USB passthrough port that illuminates and glows white. In another nice touch, channels on the bottom of the keyboard chassis help with cable management. These tunnels are meant to hold the keyboard's thick cable and have it exit the keyboard's rear edge where you like, but they can also be used to help route the cable for whatever device you plug into the USB passthrough port.
