4K Diva – User Manual
Pro Tips
-Dolby Vision: DV mode 0 and 1 travels thru 8b RGB container, so it is normal that Diva report RGB 8b when playing
such DV mode. If Diva is not directly connected to your DV TV and you have equipment in between, please first
connect Diva TX0 output to your TV input and let Diva boot up. Then disconnect and insert equipment in between.
Diva will sniff the DV string from your TV EDID and present it to your source, therefor allowing you to go thru
equipment that doesn’t support Dolby Vision.
- HDMI TX0 Output is CEC/ARC and eARC capable.

-iRule use \x0D instead of \r (or \x0A for /n) to terminate the RS232 command string.
- Some sources like X1S or K8500 might need to have powercord removed/reconnected between EDID changes
- Atmos via ARC require HDMI Cable that support 192khz ARC, even if a cable support 600MHz video signal it can
still fail for 192khz audio signal.
- You can read one, or mix two or three connected Sink EDIDs, apply forced flags and algo to it and then save it as
an EDID file, thus creating your own Custom EDID variation.
- Any 4:2:2 signals is always processed at 12b and never clipped. That’s why it mentions “up to 12b”.
- Source VS Diva frame rate reported:
Actually very few devices will report the correct frame rate. It is all about
the clock frequency, the theory is 24/1.001 = 23.976023976
BUT there is no PLL (
https://en.wikipedia.org/wiki/Phase-locked_loop
) at the source that actually gives a
corresponding clock which would yield that. So once a signal leaves the source, the clock is always off and usually
ebbs and flows, means changes all the time. We just decided to show what it really is from the particular source
rather than approximating what it should be as many are doing since they cannot report exact frame rate like we
are doing with Diva.
