Important Notes about HDCP: Sewell HDMI Splitters are all HDCP compliant which means that this splitter does NOT "strip" or "bypass" HDCP.
Also note that this splitter supports HDCP 1.x versions and the new HDCP 2.2 standard is not backwards compatible with HDCP 1.x versions. To future-proof yourself for HDCP 2.2, check out our HDMI 2.0 Splitter. In addition, the HDMI 2.0 splitters also support 4K 60Hz 4:4:4.
Splitters vs. SwitchesThis HDMI splitter will duplicate or "mirror" a single HDMI source on two HDMI displays. Both displays will show the same video and audio simultaneously, whereas an HDMI switch will take multiple sources and allow you to choose which single source will be displayed on the TV. Watch this quick video to learn about the difference between the two.
HDMI 1.4 vs HDMI 2.0
This HDMI splitter supports HDMI v1.4. For HDMI 2.0 support, check out our SplitDeck HDMI splitters.
The main attraction to HDMI v2.0 is 4K 60Hz support which is a big improvement over v1.4's 4K 30Hz standard. Improving frame rate at first might not seem like such a big deal, but twice the video bandwidth is required since it is sending twice the number of frames per second.
4K 30Hz vs 4K 60Hz
As our TVs get bigger and bigger, so does the perceived difference between refresh rates. This splitter supports 4K 30Hz while our SplitDeck HDMI Splitter Series supports 4K 60Hz, but why should you care?
As you know, video is simply a bunch of images played rapidly to give the illusion of movement. More images viewed per second equates to more-realistic video. Refresh Rates (measured in Hz) are what is used to describe the number of unique images that your TV can display per second. 30 Hz means that you're seeing 30 unique images per second while 60Hz doubles the amount of images per second.
But Wait -- I thought the human eye couldn't detect individual frames much past 24 frames per second. -- That is technically true; the human eye is thoroughly convinced that they are seeing a moving image even at 24 Hz. Higher Hz rating actually makes fast-moving objects look more realistic and less blurry/jumpy.
Battling Motion Blur -- One of the outcomes of having a low Hz rating is that fast-moving objects start to look blurry. This is actually a feature of your display-- it is trying to compensate for the jarring nature of jumpy image animation. A football travelling 30 yards/second would technically only show one frame per yard when seen at 30Hz, making that throw seem unrealistic to our eyes. The TV must therefore employ motion blur or ruin the viewing experience.
Motion blur is a lot less distracting than the actual jumpiness of an image, but neither motion blur nor jumpiness are desired when playing video games, watching sports, or some fast-action movies filmed at high frame rates. For those types of video content, we highly recommend that you do not settle for 30Hz.
Using different TV's
Most common HDMI splitters will always send the lowest common resolution to both displays. For example: 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. To "Trick" The splitter into thinking both displays are 1080p.
Does it work?
This product has an average return rate of 1.16%. This means that for about every 1000 units we sell, about 12 end up getting returned for different reasons. The most popular reason for returning this product is that "it does not support 4k@60hz". If you need 4k@60hz we recommend the SplitDeck 4k HDMI 2.0 Splitter. If you don't need 4k@60hz then this product is perfect for you.
