That's what I thought. Thank you for confirming.

Should I set "Force colour subsampling" to 4:2:2 on the Ugoos instead of Auto? If I do so and check the HDMI diagnostics screen on my tv (lg c9), then it says 422 8 bit instead of 12 bit. Even if I try to set "Force display colour depth" to 12 bit it still says 8 bit. Could you check what it shows on your lg g1 and g5?

Yeah so same as mine.
Does this mean the hdmi diagnostics of the tv is incorrect or the ugoos can only output 8 bit at 422?
Should I keep it on auto or 422 then?

you should use auto 444 12bit. There might be a bug with the 422 output and you should ask avdvplus about it since i know he made some changes about 422 in his build.

This isn't true. 422 12 bit works just fine. I don't care what the LG claims.

Amlogic MBox Meson Ref
IN TX0:
1080P23.976 74MHz 422 BT709 12b
This is why having a VRROOM is useful.

Yeah, if the HDFury device reports 12-bit, I trust that more than LG’s reporting.
On my end, CEC no longer works when I put my Vertex in the signal chain, so I don’t use it in my main home theater. I only keep one in my capture and testing rig.
In any case, 422 doesn’t really matter to me since I only watch DV using RGB tunneling.

I use it specifically to block CEC LOL I can't stand that nonsense as it doesn't work right half the time. As for 422, I agree as I use my HTPC for non-DV stuff most of the time, but it's been a discussion on multiple forums now so I figured I'd take a look.

Is there a way to send him a pm? The Issues tab on github seems kinda dead so not sure if posting there will get his attention.

Hi everyone, my father has a Sony x700U and I've tried to play some of the mp4 test files from the "Dolby_Vision_Stuff" google sheet. The one that works is "FEL TEST ST DL P7 CMV4.0 4000nits V4", and I can see the text. However, when I try to play some of the others, such as "Jurassic.Park.1993.BD NEW HDR12_ DV_Metadata_Levels_Comparison_CMv2.9_BL_FEL_Merged" I can't see any difference between the different screen shots. I tried the same file on my computer using Energy Media Player and I can clearly see the difference in the shots.
I'm playing the files off of USB stick, and I've tried to toggle Dolby Vision on and off via the menu of the X700U player.
This is the google sheet i've been referring to:
https://docs.google.com/spreadsheets/d/ ... ue&sd=true
I grabbed the files from the "screenshot comp" sheet, specifically, the "DV Comp" links in the "DoVi" column. Should I be seeing a difference on my player via usb?
If this is the wrong thread, my apologies! Please point me to the right direction if you know where this might be better received. Thank you!.

The X700, X800M2, and Oppo Dolby Vision playback is less dynamic than CMv4.0 players, but the Jurassic Park clip has a 4000-nit MDL, so it should still have an effect. Try remuxing the file to TS, maybe.
