Taking one HDMI signal and bringing it to two screens sounds difficult, but it isn’t very hard if you have the right splitter. Sewell makes a self-powered 2 port HDMI splitter that allows you to successfully split a HDCP signal and send it to two destinations, simultaneously.
The difference between a splitter and a switch in relation to HDMI is based on whether you’re using it to split an output or double an input. A switch will allow you to go between two sources going in to a single destination, as mentioned in a previous blog post. A splitter, on the other hand, gives you the ability to take a single source and feed it to two destinations. The 2 port HDMI splitter made by Sewell is HDMI standard 1.3b compliant and capable of feeding both audio and video of up to 1440p resolution to two places.
Because the hub is powered by its own 5v power supply, the standard 16 meter HDMI cable barrier between source and destination is thrown out the window. Sewell’s site features a video boasting a 100-foot range from source to screen while feeding the same HD signal to another screen at 56 feet, without the aid of a separate booster. Whether or not this is a typical occurrence is yet to be seen.
The metal enclosure appears solid enough to withstand anything normal home usage would entail. In professional environments where use and abuse are part of everyday life, this may work in a fix, but a more professional-grade solution would be in order.
Because the splitter is HDCP compliant, both devices need to be HDCP compliant as well in order for it to work. Reviews at Amazon have indicated that standard definition signals require a little tweaking on the monitors to get right. This splitter can carry a 3D signal up to 24 FPS, so it doesn’t work with all 3D content.
Overall, the Sewell 2 Port 1×2 Powered HDMI Splitter is a standard HDMI splitter at a reasonable price. Available for under $25, it should be capable of filling the needs of any home user that would like to have two televisions carry the same audio and video. If you’re looking for something a bit bigger, you might want to look in to their 1×4 model.
