Frequently Asked Questions - S3821w-C0 VIZIO
How do I connect the VIZIO S3821w-C0 converter?
Connect an HDMI source (like a Blu-ray player) to the HDMI input of the converter. Then connect the composite RCA cables (yellow for video, red/white for audio) from the converter to your TV or projector. Ensure the converter is powered via USB or the included adapter.
What power supply does the S3821w-C0 require?
It requires 5V DC power. It can be powered via a standard USB port (5V, 500mA) or using the included AC adapter (if provided). Without power, the converter will not function.
What resolutions does the converter support?
It supports standard resolutions up to 1080p input, outputting composite video at 480i. The converter downscales higher resolutions to composite-compatible formats.
Will this converter work with an older TV that only has composite inputs?
Yes, the S3821w-C0 is specifically designed to convert HDMI to composite, making it ideal for older TVs or monitors with only RCA composite inputs.
What should I do if there is no picture or sound?
First, check all cable connections. Ensure the HDMI source is powered on and outputting a signal. Try a different HDMI cable. Confirm the converter is powered (LED should light up). Also check that the TV is set to the correct composite input channel.
Does the converter support audio through HDMI?
Yes, the HDMI input carries both video and audio. The converter extracts the audio and outputs it as analog stereo via the red/white RCA jacks.
Is there an LED indicator on the converter?
Yes, a small LED light indicates power status. When powered on and receiving a signal, it should be steady blue or green. Refer to the manual for exact behavior.
Can I use this converter with a computer or laptop?
Yes, if your computer has an HDMI output, you can connect it to the converter. The laptop may need to be set to output a compatible resolution (e.g., 1080p or 720p) for best results.
Where can I purchase a replacement power adapter?
Replacement power adapters can be ordered from VIZIO's official accessories store or via customer support. It should be a 5V DC adapter with the correct polarity and connector size.
Is the S3821w-C0 compatible with HDCP-protected content?
Yes, it supports HDCP 1.4, so it should work with most protected sources like Blu-ray players, cable boxes, and streaming devices. However, some newer HDCP 2.2 sources may not work.
