LUOM YCY-2353 4K HDMI USB 3.0 Capture Card

The LUOM YCY-2353 is a portable USB 3.0 video capture dongle that accepts HDMI input up to 4K at 30 Hz and records or streams at 1080p 60 fps. It targets streamers, educators and gamers who need a driver-free way to bring console or camera footage into OBS, VLC or similar software on Windows, macOS, Linux or Android.

Thermals noise and power draw

The device draws power directly from the USB 3.0 port with no external adapter required, keeping cable count low and heat output minimal. Silent operation is assured because there are no moving parts, and the low-latency design avoids taxing the host CPU during extended capture sessions.

HDMI loop-through with 3.5 mm audio I/O

A built-in HDMI output passes the source signal to a monitor or TV for simultaneous local viewing while the USB feed goes to the computer. Front-panel 3.5 mm stereo output and microphone input let you monitor programme audio and add live commentary without extra mixers. Buyers who need 4K 60 fps capture or internal PCIe installation should consider other form factors.

Questions about this item

How do I install the LUOM YCY-2353 capture card, and what step do people often miss?

Connect the source to the HDMI input, the display to the HDMI output, and the card to a USB 3.0 port. The step often missed is selecting the 48 KHz PCM audio device in OBS or your streaming software.

What maintenance or replacement will the LUOM YCY-2353 need later?

No internal maintenance is required. If the 3.5 mm stereo jack or microphone port wears out from frequent headset changes, the card itself would need replacement.

What limit appears first during a long stream with the LUOM YCY-2353?

The HDMI input accepts 4K at 30 Hz, but capture is capped at 1080p 60 fps, so extended 4K sources are downscaled continuously.
