Note
When the bit depth of input source is 8-bit, the individual gamma adjustment for RGB is realized by the AXs
(V2.0) series receiving cards.
Low Latency
The MCTRL4K supports a low latency of less than 1 ms (when the start position of image is 0). Low latency is
used to reduce the time delay between the input of video signal to the controller and the corresponding output.
To use the low latency function, you must ensure that each Ethernet port loads the cabinets vertically during
screen configuration, as shown in
Figure 7-2 .
