Back in stock are the Decimator Design MD-HX and the newer MD-LX. These devices are some of the best built and customizable SDI to HDMI cross converters around. HDMI in and SDI output or SDI in to HDMI out. We have been using the MD-HX for years and they continue to be a great tool that can fix most problems in the HDMI realm. Using two of the MD-LX can convert your HDMI down to flexible SDI cable, run 280 ft and then convert back to HDMI. Struggling with HDMI cable lengths? These fix that.
