Change the bit n (for example bit 3 : 0x08) of register 0x00 from 0 to 1. It is recommended

first to read this register and to write the proper modified value. For example:

r 00

•

w 00 18

•

r 00

4.5.3 2K All Outputs

By default the MB-4K output a 4K image (4096x2160) split in 4 separate 2K (2048x1080)

quadrants:

the top left quadrant on output 1,

the top right quadrant on output 2 ,

the bottom left quadrant on output 3,

the bottom right quadrant on output 4.

In the case of a 2K video coming in, the 2K image will be up-scaled to a 4K image.

The MB-4K can be configured to output only the 2K image coming in on all outputs.

The configuration file for this setting is file "2K_allOutput" in /doremi/etc/beluga, see Boot

Configuration Files.

The values accepted are:

0: for 4K output

1: for 2K output on output 1 only.

The manual configuration bit is bit 2 (0x04) in register 0x00, set to value 0 for 4K output and to

value 1 for 2K output, using the procedure described above in Manual Configuration.

4.5.4 2K output

By default the MB-4K output a 4K image (4096x2160) split in 4 separate 2K (2048x1080)

quadrants, see 4.5.3 above.

The MB-4K can be configured to output only the 2K image coming in on output 1. In that

configuration, the other output should be discarded.

The configuration file for this setting is file "2K_output" in /doremi/etc/beluga, see Boot

Configuration Files.

This will return for example: 0000 CRTL

here in our example we change bit 3 = 0x08 to set it to 1

This will now return in our example: 0000 CRTL
