NovaStar: How to calculate loading capacity for receiving cards

Model Loading Capacity Hub Connectors Data Groups
DH418 128 x 512 Hub 75 x 8 16
DH426 128 x 1024 Hub 75 x 16 32
MRV366 512 x 256 Hub 75 x 16 32


How to calculate loading capacity for receiving card:

First of all, there are 2 concepts we need confirm:

Data groups, for HUB75 port each port can load 2 data groups. For MRV336 has
physically 8 HUB75 ports means can support maximum 16 data groups. For MRV366
has 16 HUB75 ports can support maximum 32 data groups.

The loading capacity which listed in this table is the maximum capacity, if higher
refresh rate or higher greyscale is necessary, please reduce loading modules. The less
the load, the higher the picture quality.

For calculation:
I will set 2 examples here.
For MRV366, the maximum loading capacity is 512256 pixels, totally 131,072 pixels. Because Mrv366 has 16 ports 32 data groups. We can set that to 3 modes: 8 data groups, 16data groups and 32 data groups. What is the different between those 3 modes? If we only use JH1 to JH4, that is, the mode of 8 data groups, then the load of 8 data groups is 512256, and the load of each port is 512256/4=32768 pixels.

That means each JH(HUB75) port can load 32768 pixels. If we need to use 5 JH ports or more, using 5 to 8 JH ports, the receiving card will be mode of 16 groups of data. Then each HUB75 (JH) port can load 512256/8=16384

If 8 ports is not enough, Need 9-16 Ports, will be the mode 32 data groups, means each
HUB75(JH) port can load 512256/16=8192.

Generally, the load width will consume more performance. For better display effect,
we usually reduce the width of the receiving card and increase the height of the
receiving card. In the same loaded pixels, to get a better display effect.
