    So far this hdmi to sdi converter works great.
    I have installed many of these units and they work very well. It does not degrade the picture quality in some installations it actually increased the picture resolution or quality.

    Great Box - Does What It Should
    I will try to write the type of review that I was looking for when I pulled the trigger and bought this converter. I run a production company in NM, and use a TriCaster Mini HDMI for most shows. I own AJA converters and wanted to compare the Monoprice units. I have both the HDMI-SDI and SDI-HDMI versions, and both work flawlessly. I sent both 1080 and 720 down the line with no issue. I also swapped an AJA box into the line and everything worked well together. I give this a huge thumbs up. Monoprice listened to earlier comments about the build - they now have metal chassis and are rock solid.

    PROS: Great Price, Solid Build, Plug and Play, Works as Advertised

    CONS: None so far.

    Worked flawlessly first attempt
    These replaced a set of very finicky Monoprice "HDMI over Single Cat6" extenders. I was so frustrated with the Cat6 extenders they would work for a while then stop and it would take a while to get them working again. When I got these setup they worked on the first attempt and have been stable.

    PROS: Stable, worked perfectly on 1st attempt, no fuss.

    CONS: Had to wait for them to come in stock

    Great Service
    These guys are great. I own several e commerce sites and they beat my expectations by a long shot. Cheaper and quicker than Amazon. This is what I expect of my company.

    HDMI to 3G SDI and 3G SDI to HDMI Converters
    I recently purchased the above Monoprice converters (PID 11749 and 10318) for evaluation for AV installations. I was totally satisfied with their performance. .

    PROS: They tested flawlessly at 1080i @ 200 feet over existing coax (160 feet of RG-6) and a 40 foot extension of
    Belden 8241 (not officially rated for SDI). Did not test them at longer runs but intend on doing so for future applications. Testing was done with a Mac Mini and Vizio 65".

    CONS: Test failed on 1080p but possibly because of non-compliant SDI coax.
    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.

    Reliable and works great. Screen doesn't go to black, though.
    I put this in place of another non-Monoprice HDMI->SDI converter that occasionally flickered. This is rock solid. It's used in an auditorium 2-3 times a week.

    The only issue I have with it is that when it is powered up, the target displays go to a dark grey instead of stay black. This causes the displays to seem bright at an angle, which has led to some comments. I've darkened the displays down a bit, but a converter should be able to produce true black, not a pseudo-black.
