How to Watch 4 Television/Sports Programs on a Single TV Screen
The SPLITMUX-4K-4RT can be used with multiple satellite boxes and computer live streams to allow up to 4 television programs to be displayed on a single television screen. In this example, the four connected sources are a wired set-top box, a laptop with a live streaming TV channel, and two wireless satellite boxes. Audio channels from each source can be independently switched or mixed, i.e. only one audio source or up to four sources can be playing at once. With this configuration, the user can display up to four television programs on one display and selectively choose which audio channels to listen to at any time. To quickly switch between the four audio channels in Quad mode, use the optional IR remote control or the SPLITMUX's front panel buttons. -
How to Cascade Units & Display More Than 4 Sources on 1 Screen
Cascade any number of SPLITMUX units, with one as the master unit and others as slaves. A slave can also have slaves, and the SPLITMUX supports any number of slave levels. After connecting the slave to the master unit, configure the cascade using the Cascade Settings page on the Web Interface.
In this example, five units are configured in a master and slave cascade with each unit configured for Quad mode. Since the SPLITMUX can only accept input resolutions up to 2K, the output of all connected slave units must be set to 2K or lower. On the master unit, only Quad and Full Screen mode will support 4Kx2K output resolutions, while Picture in Picture and Custom mode will support up to 2K output resolutions.
Notes:
1. If there is no input for a channel, its window will be white.
2. If no layering is required, the order of inputs is inconsequential.
3. If layering is pertinent to the display desired, it is recommended to connect the back layers to a slave unit and the front layers to a master unit.

"We are happy with the SPLITMUX-4K-4RT, and will reach out to purchase an additional one in the near future. I can change the orientation of the 4 different inputs to just about any way I want them. The main reason we bought the multiviewer was to display 4 inputs on a vertically positioned (portrait) wall. I reached out to a half dozen companies - from the security camera manufacturer (who had no interest in modifying their firmware on their standalone units to provide vertical orientation) to cloud based video wall companies (who assured me they could make it work, but ultimately failed). In addition to the fact that NTI was able to update the firmware to support vertical mounted displays, we like the fact that the product has a text banner that you can add to the output, which is nice especially with the text color and size options. The small, compact size allows us to put the unit just about anywhere."

"The SPLITMUX-4K-4RT device was able to meet our expectations by taking four 1080P HDMI signals to combine as a 4K signal and send out to one 65" display. This eliminated the plan to put four 32" displays on the wall. We used the multiviewer in quad display mode, and it worked without effort straight out of the box. We found the interface to be easy to use and the UI, accessible from the webhost on the device, was straight forward. We also experimented with custom sizing of the inputs using the UI, and found that to be good and very unique in this market - more so given the price point versus other competitors."
