DECIMATOR DD-LX Reviews

These consistently work for 3G 1080p

By Paul
Rated 5 out of 5
Date: 2026-05-14

We do big shows for Microsoft and had to deploy over 100 HDSDI to HDMI converters for TVs on the show floor. MS had upgraded their video signal to 1080p and we had a variety of brands we were using. We started having units over heat and fail because over 24 hours, they couldn’t handle the 3G signal. The only brand that consistently worked was the MD-LX. After that, I purchased 40 MD-LXs for my company. I have a few of the older USB Micro powered ones and thanks to techs that forced plugs in backwards, we had issues. With the new Type C power port they are rock solid. Love them.

Decimator worked when BMD didn't

By Grant

The SDI output of a Blackmagic switcher is being sent to 5 TVs through a BMD distributor. One of the TVs works fine. The other 4 are a different brand, and the picture would blink on and off. A video expert friend told me that the issue was with the color type, and that the BMD converters were not convering the color properly. This Decimator converter solved the issue.

Will this convert an HDMI signal from 1080p to 1080i?
Asked by: Kevin
I'm afraid not. This product is just a Bidirectional Converter that will change SDI to HDMI and HDMI to SDI. It does not do frame rate conversions and scaling. For that you would need to look at the DECIMATOR MD-HX, which is a HDMI/SDI Cross Converter with Scaling & Frame Rate Conversion. https://bhpho.to/2fDbJBb

question

I want to place this between a computer and projector looping through a Blackmagic ATEM. HDMI (Computer) - SDI (ATEM) - SDI (ATEM-AUX) - HDMI (Projector). The question is what happens if the ATEM is off. Will this automatically switch the projector to the Computer HDMI (Computer) - HDMI (Projector)?
Asked by: Daniel H.
As we see it, the outputs are always active so you should be good to go.

For the HDCP, is it set to pass through as copyrighted or uncopyrighted? The BM mini converters set to copyright, which is usually not an issue, but I want to covert my SDI camera feed to HDMI into a capture USB device. The USB sees the BM converter as copyrighted, won't pass it. So how does the Decimator output HDCP? Copyright on or off? Thanks
Asked by: Ben
For your use, SDI out of the camera, it should be fine. It has worked for me with all recorders I have tried. I'm surprised your BM converter has that issue if you are coming directly out of camera. I would check to see if your USB capture device isn't the problem.

Asked by: Nathaniel
The unit is able to be powered from a USB port, but if you do not have a USB port available it does come with an adapter that you can connect the USB cable and plug into a 110 outlet.
