## Long description

The A4Tech BLOODY B750N is a full-size (100%) wired gaming keyboard with USB connectivity and optical key switches designed for fast actuation and reliable desktop use. It combines LK optical switch technology with RGB backlighting and a straight full-layout design to provide low-latency keystrokes, full N-key rollover and durable construction suitable for extended gaming sessions and everyday typing.
Advantages
LK optical switches provide near-instantaneous key response with 0.2ms reaction time and zero digital latency compared with conventional metal-contact switches. The keyboard supports full N-key rollover so simultaneous key presses are accurately registered, while game mode disables the Windows key to prevent interruptions. RGB backlighting with adjustable brightness lets you customize lighting, and the screw-enhanced space bar together with dual springs and a balancing bar increases long-term durability. Built-in drainage channels and holes help protect the keyboard from accidental spills.
Suitable for
Competitive and casual PC gaming where fast key response and reliable wired connection are required
Multikey inputs such as complex in-game combinations and macros
Desktop setups that require a full-size keyboard with numeric keypad for productivity
Users who want customizable RGB lighting and adjustable brightness

How to use
Connect the keyboard to a computer using the USB cable. Use the Fn key combinations to control lighting and game features: press Fn + F12 to toggle the backlight, Fn + Up/Down arrows to adjust brightness, and Fn + F8 to enable game mode and disable the Windows key. The keyboard operates immediately on plug-and-play systems; no additional drivers are required for basic functionality. For advanced customization, consult software or system settings supported by your gaming setup if available.
Usage recommendations
Place the keyboard on a stable, flat surface and ensure the USB connection is secure to maintain consistent low-latency performance. Avoid spilling liquids onto the keyboard; if liquid enters the device, power off and allow contents to drain via the integrated channels before drying fully. Use the game mode during play to prevent accidental interruptions and adjust RGB brightness to suit ambient lighting for optimal visibility.
