Customer Ratings & Reviews

Rocketfish is one of Best Buy's own brands.The brand was released a little over 20 years ago ,and has positioned itself as one of the highend brand names in electronic accessories.  This HDMI splitter is no exception to that reputation. It offers up to 8K resolution at 60Hz with HDR10 and Dolby Vision.   Keep in mind that those specs are only acheivable if your connected devices support that reolution and features. You also have to use at least HDMI 2.1 cables in the appropriate lengths to achieve this. For max resolution at 8K a cable of 9.82ft or less is needed. For 4K resolutions you can use up to a 16.4ft cable. When hooking up the splitter, I would suggest plugging in the power before making your HDMI connections. Then plugging in your source device. When it comes to the output devices, I would plug in the highest capable resolution device first, and then your other device. I noticed that when plugging in my lower resolution TV and then the 8K TV, that I was not getting a signal to my 8K TV. I just unplugged everything and then connected in the highest res to lowest res order and everything worked fine. This device is a plug and play device, so there are no settings or anything on the splitter that needs adjusting. If anyone is curious the device puts off very little heat. To control the outputing video signals you would just adjust the settings on your source device as needed, and then your output devices. The splitter itself is very light, but feels sturdy and can be mounted to a wall or placed just about anywhere. Double sided tape is included to help keep it in place. The picture quality to the connected devices looks just as good as the original, so absolutely no complaints on the quality or performance. I checked the resolution on the connected devices and the device capable, showed 8k at 60Hz with HDR 10. I have not experienced any disruptions in the signal since installing, nor have I experienced any delay in the signal or start up lag. While visually this does not appear to have any lag, I would not reccomend spitting video signals for competitive gaming. For general video gaming purposes this should work fine. Competitive video gamers might suffer at the max resolution because this is limited to 60Hz, where as most gaming monitors can reach much higher speeds to reduce lag. Overall this splitter works great for what it is intended for. Both the video quality and audio quality are excellent.

The Rocketfish 2-output Ultra HD HDMI Splitter is an excellent and straightforward device that does what is says it does - splitting an HDMI single into two HDMI signals. The device carries both audio and video through the splitter to the two devices that the signal is connected to. This device is ideal for use case where one needs to split a single source such as a DVD player, game console, or TV box to have the same output shared to two devices. The noted features of this device are: - Splits one HDMI Source to two HDMI Outputs - Compatible with resolutions up to 8K@60Hz - Rubber feet prevent scuffing of your desk or table. - Mounting keyholes to support flexible placement (wall mounting - screws not included) Additional specifications include: - HDR10 and Dolby Vision HDR compatible. - HDCP Compatibility: HDCP1.4, HDCP 2.2/2.3 - DTS HD, Dolby TrueHD lossless digital audio compatible. Included in the box: - HDMI Splitter - AC Adapter - 6 ft USB to USB-C Cable (for power adapter) - Quick Set up Guide (English and Spanish) My testing setup consisted of a Laptop with an HDMI output and two monitors with HDMI Inputs. Setup was quick and easy and consisted of connecting the laptop to the Input port of the splitter with an HDMI cable (not included) and the two monitors to the output ports of the splitter with an HDMI cable for each (not included) and then connecting the included power adapter and included USB cable to the splitter and plugging in the power adapter. Turning on the monitors and setting their input to the HDMI port resulted in each receiving the video and audio output from the laptop. A few notable items found in the user guide: - For 8K resolution support the HDMI cables should be HDMI 2.1 and be no more than 9.84 ft/ 3 m in length. - For 4K resolution support the HDMI cables should be HDMI 2.0 cables and be no more than 16.4 ft/ 5 m in length. - Actual output resolution is related to the host, display, cables and your HDMI splitter's configuration. From there is was use the laptop as normal with each monitor receiving a copy of the output. I could easily see this device being used to support trade show setups or other use cases where having mirrored output would be useful. I could also see this driving two television units for displaying video and/audio for sporting, religious, or community events.

The perfect solution for complicated tasks. Plug and play, that's how easy it is to use!
