We used this to extend a screen to a remote area of our facility over our existing network. This was a temporary setup so we didn't want to invest in a more expensive fiber system, so we took a chance with this device. In total the distance between the sending switch and receiving switch was about 1.5 miles. We use a mix of singlemode & multimode fiber connecting the switches back to the core where everything is centrally connected. This system connected almost instantly upon obtaining an IP address. The system was in production for 3 weeks running 24/7 and we did not have a single issue.

These are not like the other two sets that I bought, these look different and are causing a broken audio signal at the end of a 50 foot cat6 cable!

Worked great for HDMI ins and outs. Going from Mini DP IN to HDMI OUT resulted in visual compression that was noticeable.

Good alternative for a long run, up to 80-90 feet. Depends on how much signal youre pushing, Basic HDMI goes farther than a bigger signal 4k 3d return etc. Another factor is connectors. a straight run goes farther than going from source to a wall pass through, long run, another wall pas through etc. Cat6 cable will go a little farther than Cat5.

I would recommend this extender, works well.

Works Great!

Did exactly as it was described to do.

I installed 12 of these units, all under 30m. NONE of them worked consistently!!! They all quit working within an hour, and sometimes never came back on. I used 5 different HDMI extenders on this last install of 30 TVs, and this one was the worst. My lesson learned was, only the units that had power supplies on the receiver worked consistently. I bought 12 of these and it cost me over $1,000 in labor troubleshooting and resolving all of the problems.

I knew about this product from having rented them.
We couldn't get the fancier product by Crestron to work, so the rental house said, try these cheaper ones.
They worked perfectly. Now I bought my own. I just used them at a large event and the worked with out a hitch--great!!

I'm using these for my church with a single transmitter and two receivers at 1024x768 for a projector and TV. I have a test projector that I was using that seemed like the scaling was off (cropped off the outer 25% of the image). It's not the actual projector that I was going to use, which worked fine, but internet searches show that this can be a Projector/TV setting of some sort that needs to be set.
Overall, seems to be great for what I need and allows me to reuse existing ethernet wiring. I'll likely purchase more kits and use the receivers in other areas as well.

If you are using these on your existing switches: The TCP signaling is broadcast traffic, so it will saturate your network (especially Wi-Fi) unless you create a dedicated VLAN. I thought it was multicast, but my switch is showing it as broadcast traffic, even with IGMP snooping on. You might want to make sure that you don't have broadcast storm control turned on or at least not very restrictive. They run at 100Mbps, so if you use gigabit, it won't saturate your switch uplinks/trunks.
