Can this be set to off by default. Otherwise, Dolby Vision is broken by default.
With this change above it switch to Display resolution ADJUST : 1920x1080 @ 25.00 - Full Screen (39) (weight: 0.000)
But 3 seconds later: Display resolution ADJUST : 1920x1080 @ 50.00 - Full Screen (16) (weight: 0.000)
So Kodi is not designed anymore to not use double refresh option.
But again: what purpose is on this?
Why not use 50/60hz for 25/30hz?
When 25fps content is outputted as 50fps, it causes the TV to repeatedly switch DV on and off causing it the handshake to fail. It seems that Double Refresh causes a sequence of DV packet - No DV Packet - DV Packet - etc which breaks DV support.
The Double switch cause Dolby Vision to blink on and off, but then work.
So the choice is two switches and working Dolby Vision or 25 switches a second and no working Dolby Vision.
Can believe it, but I have no DV 25hz sample.
And if it causes a issue the reason must be fixed, not prevent at all.
How about making this change for now and then a separate commit can be made in the future to change the default action?
Can someone please provide a sample so it can be looked at?
on my end, the HDMI handshake issues with 25fps played at 50hz is totally random. I was watching Netflix’s show ‘‘Kaos’’ and it randomly happened one or two times per episode. Here’s another 25fps sample
I have played both sample provided.
They play back perfectly with no flashing.
They are detected as 25fps, the display switches to 50Hz, no flashing whatsoever.
Am I missing something? Display is LG OLED, so TV led Dolby Vision, if that matters and I have missed it.
Running yesterday’s nightly.
I also do not see any issues. Without whitelist it plays perfectly with 50hz. With whitelist in 25hz, also no problem.
It might depend on the TV.
I don’t see any debug log not EDID dump.
I’m in the middle of travel right now, but can provide one when I get back. Really grateful to you for looking into this issue.
@R3S3T_9999 Do you think you can provide a log in the meantime?
Could it be an issue with cable quality?
According to the table in this article, 4K/25 requires a bandwith of 8.9 to 13.4 Gbps depending on bit-depth. 4K/50 can require up to 24 Gbps:
Did you try any 4K/60 DV material to rule this out?
Well, I have premium-certified monoprice HDMI cables and watched Gemini Man 60fps like 3 times on my x800m2 without a single HDMI dropout using the same cables I use with my ugoos right now. 25fps content is played natively at 25fps on the x800m2 so I don’t know, maybe my AVR doesn’t like 50hz.
Both samples played back at 25fps with am6 connected directly to C1.
