What player did you use for playback?
The C2 doesn't support proper profile 7 Dolby Vision playback, while the C8 does.

Right, thanks. I'm seeing the same.
It might be the graded trim passes difference I mentioned previously. Not sure when I'll be able to test it out, hopefully soon.

I'm not exactly sure what's happening, but I do get very different images from the internal player vs. my FireTV Stick 4K.
It's hard to tell if the cause is the L2 trim passes (this was on the mountain + sun shot). I can't really tell the different trim samples apart. I'll have to check out the eagle beak later.. Some samples: https://mega.nz/file/kItlgQ6Z#ZiKDpD...SduJNJiYxSv0mA They all look the same to me, so maybe something else is going on.

I generated DV with your dovi_tool/madvr. The C2 still has very strong color saturation(even at warm 0) compared to the C8. So it can't be coming from the trims. But then, the eagle beak now looks the same. So that paler brighter yellow is coming from the trims.
I don't see any difference between plex internal app C2 and my x800m2. I'll check my Shield. I don't have the camera nor the space those youtube reviewers have but FWIW: https://www.youtube.com/watch?v=qYNJvh6PPI4 left = 65" C8 right = 77" C2 Obviously, the difference is amplified but it gives a good idea. @SamuriHL is it the same on your G2? TVs don't have to be side by side, the difference is quite obvious. Code:
"cmv29_metadata": { "num_ext_blocks": 3, "ext_metadata_blocks": [ { "Level1": { "min_pq": 0, "max_pq": 3481, "avg_pq": 2803 } }, { "Level5": { "active_area_left_offset": 0, "active_area_right_offset": 0, "active_area_top_offset": 0, "active_area_bottom_offset": 0 } }, { "Level6": { "max_display_mastering_luminance": 10000, "min_display_mastering_luminance": 50, "max_content_light_level": 10000, "max_frame_average_light_level": 1676 } } ] }, "cmv40_metadata": { "num_ext_blocks": 3, "ext_metadata_blocks": [ { "Level9": { "length": 1, "source_primary_index": 2 } }, { "Level11": { "content_type": 1, "whitepoint": 0, "reference_mode_flag": true, "reserved_byte2": 0, "reserved_byte3": 0 } }, { "Level254": { "dm_mode": 0, "dm_version_index": 2 } } ] } }, "rpu_data_crc32": 1589861294 } Parsing RPU file... Exporting metadata... Done. [{"dovi_profile":8 Quote:
Plex internal: 600nits looks like the original on C8 1000nits on the C8 still has the brighter yellow but looks strange. On the C2, both look the same just like the original. Maybe a sample with L2 600nits set to 2048 and 1000nits to strong values ? And another sample with L2 600nits strong values and 1000nits 2048 ? Last edited by Kuler087; 25th June 2022 at 18:44. |

If the C2 is just overall more saturated without any trims, then I guess the internal mapping engine just behaves differently..
Though you made the RPU CM v4.x, which only the C2 supports. It might trigger different processing, too. There's no way to tell which is supposed to be correct.. FWIW I'm pretty sure the C2 is closer to madVR's saturation, since I remember the C8 being pretty different.

I think I found a way to override mastering metadata in madVR!
1. Set your default HDR profile to TM to a DPL which you want to use for the metadata override 2. Switch to your actual desired HDR profile with a different DPL using a hotkey (hotkey not required but makes the workflow convenient) The original metadata should stick despite changing profiles. Finally, a way to make the OLED track the way we want while using any DPL setting we want, it just involves one manual step of hitting a hotkey each time.

Isn't this a driver/madvr/tv issue? I think it worked on the B8 in the past for me, the 19th WB value should change in the TV. I can check it later.

I'd describe it as taking advantage of a bug in the latest madVR version (it exists in 159 and I don't know how far it goes back) where it doesn't re-send metadata when switching profiles, in order to achieve what we wanted. I suppose there could be something else in my system contributing.

I'm pretty sure I remember the metadata being sent (properly set) on the first signal only on my C8.
So it's not something new.

I didn't think it was new, because as I thought about what I experienced during some of my testing a while back, it would explain what I was seeing. But it's an easy enough way to achieve the metadata override that madshi has not wanted to add for whatever reason.

We will see, I applied the Dovi 2pt WB hack to get proper black, and slowly break it in. One thing is for sure, it's big

77" WRGB or 65" QD-OLED?

Good question, I won't buy Samsung, maybe Sony, but if ABLs can't be turned off then it would be a no go for me. Next year it should have 77" as well, I only wish LG would have a qd-oled lineup soon as well

The trick to get proper black doesnt work for me. I tried as low as -3.
Not even contrast 99 works (this worked on my C8). So far though, I did not notice raised black in real content. I noticed it all the time on my C8. BTW, I just measured my C2 HDR10 mode, and it's very bright!!! Last edited by Kuler087; 29th June 2022 at 01:22. |
