The SEETEC ATEM156 can be used as a companion to switchers that don't have a multiview function, such as the Blackmagic ATEM Mini switcher. It allows you to view four DCI/UHD 4K HDMI signals in a quad split. Four HDMI loop outputs let you connect your four signals to the switcher. You can move any signal to any window in the quad split. A PiP image can also be displayed in each window. Alternatively, a dual view or single image can be displayed on the screen, also supporting Picture-in-Picture. Dual view can be set up in a vertical or horizontal split, and you can set one side of the split to be larger than the other.

The ATEM156 features a 15.6" IPS display with a 1920 x 1080 resolution, 250 cd/m² brightness, and 170° viewing angle. Software features, such as peaking and false color, additionally let you analyze each image. A 3.5mm stereo headphone jack on the front panel allows for audio monitoring.
