Frequently Asked Questions - HMMS-22 Holland Electronics
How do I connect the Holland Electronics HMMS-22 converter?
Connect the HDMI source (e.g., TV box) to the HDMI input using an HDMI cable. Then connect the Composite RCA cables (yellow for video, white/red for audio) from the converter's output to your TV or monitor's composite input. Finally, power the converter via the included USB cable into a 5V USB port.
Why is there no video output from the converter?
Check that the HDMI source is powered on and outputting a compatible resolution (480i/576i/720p/1080i/1080p). Verify all cable connections are secure. Also ensure the converter is powered via USB. If the source outputs HDCP-protected content, it may not display on non-HDCP displays.
Does this converter support 4K input?
No, the HMMS-22 supports maximum input resolution of 1080p. If you feed a 4K signal, it will be downscaled to 1080p, but it may not work with all sources. For best results, set your source to 1080p or lower.
Can I convert from Composite to HDMI using this device?
No, this converter is unidirectional and only converts from HDMI to Composite (analog). It cannot convert analog to digital. You would need a different converter for that purpose.
What audio formats are supported?
The converter extracts stereo audio from the HDMI stream and outputs it via the RCA red/white jacks. It supports LPCM 2.0 audio. Dolby/DTS multi-channel audio will be downmixed to stereo.
Why is the video in black and white?
Ensure the composite yellow cable is plugged into the correct input. Also check that your display is set to the correct AV input. If using a PAL source with an NTSC display (or vice versa), you may get black and white or distorted picture. This converter supports both NTSC and PAL but does not convert between them.
How do I clean the converter?
Disconnect the power and cables, then wipe the exterior with a soft, dry cloth. Do not use liquids, solvents, or abrasive cleaners.
Does this device work with game consoles?
Yes, it works with any HDMI source such as PS4, Xbox One, Nintendo Switch, etc. However, for latency-sensitive gaming, note that analog conversion may introduce slight delay.
Is the converter plug-and-play?
Yes, after connecting cables and power, the converter should work automatically. There is no software to install. The LED indicator on the converter will light up when powered.
What if the converter gets hot during use?
The converter may become slightly warm to the touch. Ensure it is placed in a well-ventilated area and not covered. If it becomes excessively hot, unplug immediately and contact support.
