This article covers Guermok HDMI キャプチャーボード USB3.0 4K60FPS・2K120FPS録画 USB-C.
Overview
The Guermok HDMI Capture Board (model GM-29F-Silver) is a compact USB 3.0 capture card that accepts video input up to 4K@60Hz. It's designed for gamers, streamers, and remote workers who need a simple way to bring HDMI sources into their computer. With both USB-C and USB-A connectivity, it works with a wide range of devices, including laptops, tablets, and desktop PCs.
One of the standout features is its plug-and-play operation—no drivers or external power required. It works with Windows 7/8/10/11, macOS, Linux, Android 5.0+, and iPadOS 17+, making it a versatile tool for various setups. As an entry-level capture card, it offers an affordable way to start streaming or recording without investing in high-end equipment.
Connectivity & Compatibility
The card connects via USB 3.0 and supports both USB-C and USB-A ports. An included USB-A male to USB-C female adapter ensures compatibility with older PCs that lack USB-C. When using a USB 2.0 port, the maximum resolution drops to 1080P. If you're getting 1080P even on USB 3.0, try rotating the USB-C connector 180 degrees and reconnecting.
It supports a broad range of input devices: iPad, MacBook, Nintendo Switch/Switch 2, PS3/4/5, Xbox One, DSLR cameras, webcams, Meta Quest 3/3s, TV boxes, HDTVs, and DVD players. Note that this is a one-way HDMI-to-USB-C device; using it in reverse (USB-C to HDMI) may cause signal loss. For PS5 users, disable HDCP if you encounter a black screen.

It positions itself as a budget-friendly alternative to premium capture cards from brands like Elgato or AVerMedia, offering 4K input capability at a fraction of the cost.
