    HDMI or Mini HDMI? Based on the picture it looks like full sized HDMI. Is this converter itself referred to as "Mini" (compared to the full sized version) not the HDMI? Since there is also a "Mini" 3G-SDI to HDMI Converter that looks exactly the same.

    BEST ANSWER: Thank you for your question. These units will use the full size HDMI port. "Mini" is just referring to the size of the converters and not the HDMI ports. It will be the same with the 3G-SDI ports.

    If this device can transmit audio will I need a SDI to HDMI converter at the receiving end? I am connecting to a Black Magic ATEM Television Studio switch.

    I notice it’s compatible with RG-59 coax but it doesn’t mention RG-6. Can I use RG-6 coax cable instead of RG-59?

    BEST ANSWER: Had an issue with one bad 10318..sent back received a replacement no issues since...But note, i have experienced flickering & no signal issues with the Mini 16060 coming off the 10322 sdi amp...Finally, replaced the 16060 with another unit from another source...after doing so worked like a charm with no issues those far....Insure cabling & crimps on bnc are secure...good luck
    Does it support drop frame rates such as 29.97 instead of 30p?

    Does this also support HD-SDI 1080i?

    Will this converter transmit audio from the HDMI?
    New User U on Feb 14, 2018
    BEST ANSWER: I have multiple converters and all of them seem to do this, I have not tested the audio on this specific unit, but I can say it likely will. I am a broadcaster and the HD-SDI/3G-SDI standard and HDMI are almost identical. The HDMI has HDCP for copy protection added in and HDMI has no VANC (Vertical Ancillary) to carry Closed Captioning. The HANC (Horizontal Ancillary) is where that carries the Digital audio of up to 16 channels in SDI.
    Can these be on all the time? For comercial install
    jonathan v on Jul 22, 2018
    BEST ANSWER: As far as I know, they can stay on 24/7/365. There is a small circuit board inside that draws little power. Usually the wall wart power supply dies first. Both units need to be kept cool. Don't put them in an enclosed space.
    I'm trying to run HDMI to a standard monitor over a single RG6. Will this unit convert to SDI for the coax run and convert back to HDMI with opposite convertor on other end?

    Use RG6 Quad Shield, what monoprice stocks works, you can also use bulk coax from home improvement stores. 1080p allows you 100 meters, I've stretched that to 150 meters and had it work.

    Make sure you use 75ohm BBC connectors, 50 ohm are more common and won't work right.

    Biggest complaint with these units is that if the video is switched or turned off and back on you sometimes have to power cycle the converter.
    can it be powered from the tv usb?
    New User U on Jun 7, 2018
    BEST ANSWER: Looks like it is 5V but needs 2A. Most USB ports are 500mA to 2A, so you would want to check your TV manual on if it could provide that much current. I doubt this unit actually pulls that much. Likely what its PS is rated for. Switching supplies are regulated and not always is full current used.
    Would this device work with a Blu-ray player feeding a BMD DeckLink Quad 2?
    A shopper on Apr 4, 2018
    BEST ANSWER: If the BDM DeckLink Quad2 has a SDI (BNC) connector on the unit then YES! The BlueRay player will send it's signal out over an HDMI cable into the converter which will send the signal down the SDI cable to your unit's SDI Input
    Can I go from this directly to the Monoprice 110323 3G SDI Splitter?

    BEST ANSWER: Yes you need one HDMI to 3G Converter (sender) to the 3G splitter. Then one 3G to HDMI receiver for each monitor.
    will this work for 1080p 60fps for a black-magic switcher?
    A shopper on Apr 19, 2017
    BEST ANSWER: Yes, it will work just fine the Monoprice has a broader range then the B.M.. you would have more of a hand shake problem if it were Monoprice switcher to a B.M. HDMI to SDI converter.
    How long is the video frame delay from HDMI to SDI output?
    Alex N on Jun 27, 2017
    BEST ANSWER: That depends on what you are running the SDI output into. I am running in to a Blackmagic Quad 2, then into a PC, and outputting to projectors. My total latency is 4 ms - that's it. Barely noticeable. From my experience, there is virtually no latency from the converter itself.

    Perfect Fit
    I ordered this to be able to run PowerPoint out of a Macbook Pro through HDMI, converted to SDI, and into a TriCaster 850 Extreme. This worked flawlessly and I was so pleased that I decided to see what else I could do with it. I then decided to hook up a school issued Dell laptop (I teach television production) and see if I could Skype to it and thereby have live reports from anywhere in the world. The short answer is yes, yes I can.

    Now I will be able to have live Skype reports in our school morning show. I love how this is giving my students a chance to do it like the professionals do it. Excellent product, and a perfect fit for our needs.

    I already have plans to purchase several more of these. I also purchased mic cables and microphones from monoprice.com and I have found my new go-to company for technology needs. Fantastic products, amazing prices.

    PROS: Easy setup

    CONS: I hate that it has to be plugged in to power, but that is a necessary evil. No obvious cons.

    Works with almost everything
    One of the SDI connectors came loose on the first use. I took the unit apart to tighten the retainer nut and found a broken snap ring. No way to re secure the connector except to solder it to the frame.

    OK, that fix worked and the event went well.. Now we find that if you run the Monoprice converter HDMI to SDI and then use another Monoprice converter to bring SDI to HDMI back again, some monitors will not see the signal. The ACER S11HL is such a monitor. Something happens in the boxes that these monitors do not like. All of the rest of our monitors are happy. The signal is 1920x1080P @ 60hz. On a distribution amp we can split the output and view the images on other monitors, but not the ACERs. Unfortunately we have six of the ACER S11HL monitors.

    Quality at a reasonnable price
    We bought this HDMI to SDI to repace one that had failed after a few years of intense usage. The quality of monoprice products is comparible to other brands and works perfectly in our KH. The shipping was fast to Canada without any surprises. Will buy again directly from Monoprice.

    Great and ecconomical solution
    I found similar items at B&H for 40% more with only one SDI output (that is all that I really required) but this actually has dual outputs for a fraction of the price of the ones on B&H! I used them and they worked flawlessly!
