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
between the splitter and the 720p TV. That way, each TV will display the highest possible resolution.
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.
