"Great experience and exactly what I was looking for. I would definitely shop with Sewell again."


If you have a 1080p TV and a 720p TV, the signal sent to both from the splitter will end up being 720p unless you use a downscaler between the splitter and the 720p TV. That way, each TV will display the highest possible resolution.

HDMI Splitter Diagram

While only 2 displays are shown, a 1x4 HDMI Splitter works the same way, outputting to 4 displays instead of 2.

Take a single HDMI source and multiply it by 4 with the 4-port HDMI splitter which duplicates and sends the same HDMI signal simultaneously to 4 seperate displays.

High Quality Construction

Wire gauges and the high quality construction of this splitter allows for an operating frequency of 225MHz. HDMI 1.3b and 1440p resolutions are supported, future proofing you from many years of future HDMI development. The heavy-duty cool metal enclosure protects the insides and keeps the unit cool by aiding in quick heat absorption and dissipation.

Pros: Simple to set up just plug into source and plug into multiple outputs. I used it on my Direct tv dvr to view in the main room, the exercise room and added it to an upstairs office by installing the HDMI to cat 5 device . Works great in all rooms.

HDMI bad

Pros: This device will allow you to output one HDMI source to four HDMI inputs. I am using it as part of a training setup to put the same information on four HDMI displays. There is no noticeable signal degredation. Well worth the price.

Cons: It can only be used as a one way device.

Other: very compact and does have its own power supply.
