Live HDMI or USB-drive playback
Use HDMI for a live video source, or select USB to play supported videos and pictures from a flash drive. Front-panel controls provide brightness adjustment, source selection, scaling and freeze. A button lock helps prevent unintended operation.
The PDF’s rear-panel and basic-parameter tables specify a DC 12 V, 1.5 A supply; its front-button description refers to AC input. Use the labelled DC input and confirm the supplied power adapter.

HD-KV210 frequently asked questions
What does the KV210 three-in-one design include?
It combines video processing, two Gigabit LED output ports and USB-drive media playback. The output ports connect to compatible receiving cards for LED display data.
Does HDMI and USB playback use the same frame-rate limit?
No. HDMI input supports up to 1920 × 1080p at 60 Hz, while USB video playback is specified up to 1920 × 1080 at 30 Hz. These are input/media limits, separate from the LED pixel load.
Can KV210 drive a 3840 × 2500 LED screen?
No. The document gives 3840 as the maximum width or 2500 as the maximum height, while total loading remains 1.3 million pixels. The two dimension limits cannot be combined into an unrestricted canvas.
Which USB media files can it play?
The PDF lists video containers mp4, avi, mpg, mkv, mov, vob and rmvb, and image formats jpg, jpeg, png and bmp. Place media in the drive root directory and use supported encoding; a file extension alone does not establish codec compatibility.
Is an infrared remote included?
The remote is optional in the specification. Confirm it on the order if needed. The unit also provides front-panel controls and a USB-B connection for computer configuration.
