This article covers バッファロー USB Type-C HDMI 変換 ケーブル 2m 4K(60Hz)対応 マルチディスプレイ ミラーリング BSCHD20BK.

Overview

The Buffalo BSCHD20BK/N is a USB Type-C to HDMI conversion cable designed to output video from smartphones, tablets, and laptops equipped with a USB Type-C port to TVs, monitors, or projectors with HDMI input. It supports resolutions up to 3840×2160 at 60Hz, delivering crisp 4K visuals without compromise. The cable length is 2 meters, offering practical reach for desktop or living room setups. This product is sold as a 3-pack, making it ideal for users who need cables in multiple rooms, offices, or travel bags. It requires no driver installation — simply plug and play.

Connectivity & Compatibility

The Type-C end connects to smartphones, tablets, and PCs with a USB Type-C port that supports DisplayPort Alt Mode. The HDMI end connects to TVs, monitors, and projectors with HDMI input. Note that devices such as iPhone 16e, iPhone 17e, and iPhone Air, which do not support DisplayPort Alt Mode over USB-C, are not compatible. Always verify your device's specifications before purchase. Both extended desktop (multi-display) and mirroring modes are supported, allowing you to expand your laptop's workspace or share your phone's screen on a larger display.

Product Info

Released around 2024, the Buffalo BSCHD20BK/N is available through Buffalo's official channels, electronics retailers, and online stores. The 3-pack typically retails for around ¥5,000, which breaks down to roughly ¥1,700 per cable — excellent value for a 4K/60Hz-capable adapter. The standard manufacturer warranty is one year. No additional accessories are included beyond the cables themselves. Market positioning is entry to mid-range. While it doesn't offer USB data or charging passthrough, its 4K/60Hz support and multi-pack pricing make it a strong budget-friendly choice for users who simply need reliable video output.

Best Use Cases

Remote workers and dual-monitor users: Connect your laptop's USB-C port to an external monitor for an expanded desktop. The 2-meter cable provides flexibility in desk layout, and the plug-and-play nature means zero setup time. Not suitable for devices lacking DisplayPort Alt Mode. Smartphone-to-TV screen sharing: Mirror your phone's display to a TV for sharing photos, videos, or mobile games with family and friends. Wired connection eliminates wireless lag and instability. Check device compatibility first. * Multi-location users: With three cables in one pack, keep one at home, one at the office, and one in your travel bag. The per-unit cost is low, making bulk purchase economical. However, if none of your devices support DisplayPort Alt Mode, this product is useless.

Things to Consider

The most critical factor is whether your device supports DisplayPort Alt Mode over USB-C. Many Apple products (iPhone 16e/17e/iPhone Air) and some Android/Windows devices do not. Always verify your device's specifications before buying. This cable is for video output only — it does not support USB data transfer or charging. If you need a hub with additional ports, look for a USB-C hub instead. The 2-meter length is standard; for longer runs, consider an active repeater or extension cable.
