4K 30Hz vs 4K 60Hz
As our TVs get bigger and bigger, so does the perceived difference between refresh rates. This splitter supports 4K 60Hz while some of our other splitters outside of the SplitDeck series support 4K 30Hz, 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 played 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 watching action flicks, playing a video game, or watching sports. For those types of video content, we highly recommend that you do not settle for 30Hz.

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.
