(1 star) Will not work at 20m

By:
System simply refuses to work at my required distance of 20m. I've bench tested the equipment using 2m cables and it worked fine, but when connected to the 20m cables, there was no video transmission at all. I also tested the transmission over CAT5e and CAT6, but useless.

Sam, Customer Service
Thank you for your review of ST121SHD30. We apologize that it isn't working as desired yet. Are you using 2 Ethernet cables between the transmitter and extender at 20m? Both are required for operation. Please be sure that your cables are a direct connection between the transmitter and receiver. Equipment such as switches and routers will cause the traffic to not pass properly. Keystone jacks and patch panels can introduce more possible points of failure as well. Please also know that we have Technical Support Advisors available 24 hours a day, 5 days a week, to provide support. If you have any further problems, feel free to reach out to us using one of the contact links at the bottom of https://www.startech.com/support

Thank you for sharing your review of our ST121SHD30. I apologize for the issues you've had with setting it up! Please ensure that you are using 2 Ethernet cables between the transmitter and receiver as this unit will not function properly with only 1 cable. This extender is covered by a 2 year warranty and free lifetime technical support. Our Technical Advisors are available 24 hours a day, 5 days a week, to provide support. For further troubleshooting, I recommend reaching out to us at 1-800 265-1844 or www.startech.com/chat Sam, StarTech.com Support

(2 stars) This product only works partially as advertised

By:
This product only works partially. The transfer of picture and sound over LAN works as advertised. The IR extender feature of this product however only works partially, and with some major drawbacks. Constantly when trying to use the IR extender feature, the transfer of the hdmi signal breaks and the LED light on the reciever unit dies, a few seconds later the LED lights up again and the picture returns. Over time when you use this IR extender feature theres a high chance of losing hdmi signal on the reciever unit, and this interruption of picture and sound renders this feature useless.

By:
It just works, when connected correctly. 1080p over 2 Cat-5e cables can be spotty (it drops out from time to time), but using dual Cat-6 works flawlessly. Just remember that port1 to port1, and port2 to port2. Getting them crossed will not work. The IR plugs work perfectly. And for the record: The runs were 78', direct from box to box.

(1 star) It wouldn't work over a 50 foot Cat6 cable.

By:
It wouldn't work over 50 foot of Cat6 cable. So we went down to fry's and bought a different style and it worked fine.

Hello Fred, Thank you for taking the time to review our ST121SHD30 HDMI Extender. We are sorry to hear the extension was not working over the 50ft CAT6 cable and we would like to offer some help. With this model of extender it supports up to a maximum of 100ft of CAT5e or CAT6 cabling. Was the extender tested using two cables? It does require that two cables be used for the extension and both cables must be the same length. If two cables were used, are you able to try the extender in a “test bench” setup using two short Ethernet cables? Another potential issue is that not all HDMI video sources are able to provide the power required by this extender. A few examples are phones that use MHL adapters, and some models of cable or satellite box. If the video source used may be one that is unable to provide the required power we would recommend our ST121SHD50 model which comes with an external power supply. Please note the ST121SHD50 does not support any IR extension functionality. Here is our ST121SHD50: http://www.startech.com/AV/Extenders/HDMI/HDMI-over-Cat5-Cat6-Extender~ST121SHD50 For more troubleshooting steps, please refer to this article which can be found on the support page for the ST121SHD30: http://www.startech.com/faq/video_extenders_general#ST121SHD30 We are always here to help with our free lifetime technical support.
