RGB lighting experts combine 120 gaming keyboards into an impressive screen with 12,600 keys as LEDs

Modern gaming keyboards can display different lighting effects. An RGB expert combines 120 such keyboards into one screen and shows the classic shooter Doom on it.

Hardly any gaming PC today can do without RGB lighting. Almost all components of a computer are now available in a glowing version to create a small RGB work of art. You can also have your peripheral devices shine in a wide variety of color variations.

The experts at SignalRGB for the individual control of RGB LEDs have now demonstrated what you can do with 120 illuminated gaming keyboards. All keyboards combined create a screen of enormous dimensions, which our colleagues from 3djuegospc.com also reported on.

120 illuminated gaming keyboards form a huge monitor wall

What kind of screen is this? The screen was presented at this year’s Pax East gaming trade fair in the United States. The construct consists of a total of 120 gaming keyboards that were connected together.

The keyboard model used is unknown. If you assume that every input device has at least the standard layout (105 keys in Germany), this results in around 12,600 keys without special macro keys, which together can display different color effects.

This number is enough to display the old first-person shooter Doom on the keyboard monitor wall and to be able to play various videos of Internet memes. The image quality is not optimal, but is greatly enhanced by the available color tones.

How many colors are possible? The RGB color space is made up of the primary colors red, green and blue. It is used on PC monitors, TV screens and smartphones. By using different weightings when mixing the 3 basic colors, you get other colors.

The color depth used is crucial. The color depth defines how many displayed colors are possible in total. Computer monitors typically use 8 bits. This means that each of the three primary colors is assigned a value between 0 and 255.

If you add these combinations together (256 x 256 x 256), there are 16,777,216 different colors that can be used (via mechanical-keyboard.org).

What technology is used? In order to be able to use all the color options in the RGB color space, special software is used. Using the SignalRGB tool, each key is addressed individually, thus achieving individual adjustment of the lighting.

SignalRGB is freely available and can be used by anyone who has a compatible motherboard and illuminated RGB components in their gaming PC.

What do others say about the construct? The keyboard wall is very popular in the community. A 30-second video on YouTube and TikTok with a game scene from Doom is being heavily commented on.

  • blackwolf0933 thinks: “That’s damn impressive.” (via YouTube)
  • hamburger454 is interested in technology and asks on YouTube: “What is the refresh rate of the keyboards?”

    • Alluding to how it has become a trend to play Doom in the most unusual way possible, sorry_youre_stupid on TikTok says:

  • “People will play Doom on anything imaginable except a computer.”

    • The wall of gaming keyboard screens is very impressive, but it wasn’t the first idea to use RGB lighting for such purposes. A tinkerer also used SignalRGB for his project, combining almost 200 RGB fans: hobbyist combines 192 case fans into a screen with 3,840 LEDs and “plays” Tetris and Doom on it
