That’s OK if you have TV led DV. There are many TVs like the brilliant Sony ZD9s which dont and need player led DV.
If it can’t be achievedso be it but there is definitely a need.

Not if you use a projector. Mine (JVC NP5) didn’t come with TV LED.
I have a Hisense projector which does TV led fine.
Unfortunately we are not looking at supporting player led at this time
According to the data sheet of your projector, it doesn’t support DV at all.
Are you using a Vertex to enable support?
Any chance you will look into HDR(+)→DV after FEL is working? CoreElec with CPM A14 supports this and its a great experience, especially with TVs that handle DV better than HDR (or dont handle HDR+ at all)

We’ll see. No promises either way as always with DV.
Out of curiosity, do you know what TVs handle DV better than HDR10+?
Do you know of any specific clips where that becomes quite obvious to the eye?

Afaik any LG OLED as they don’t support HDR10+ at all. Luckily nowadays more content with HDR10+ also has DV but some content still only exists in HDR10+.
Summary
Regarding HDR10: I read multiple times that older LG OLEDs (CX-C2) have increased issues when it comes to tonemapping & posterization/banding on HDR10 compared to Dolby Vision, while this might be due to mastering differences in some cases it certainly seems to affect older LG OLEDs more.
For the months I had the Ugoos AM6b+ with my LG OLED CX I really came to enjoy the CPM/VS10 HDR→DV conversion due to three areas:
- Tonemapping: much improved on DV compared to LGs Dynamic Tonemapping for HDR
- Posterization/Banding: the only reason I even tried HDR→DV was because I read multiple times that engaging CPM/VS10 for HDR would help here on older LG OLEDs and for me it did
- Lip sync: maybe my TV is just faulty but getting perfect lip sync across HDR and DV content was a nightmare. With HDR→DV I could finally stop adjusting and enjoy movies instead
Sadly I can’t give any good example clips as I returned the Ugoos AM6b+ due to hardware issues (unrelated to DV) and I switched to a Vero V instead (hoping for FEL).
Thanks for the insight.

Yes, I use an Vertex 2.
I wonder how G5 owners feel about that too since apparently HDR is horrible on G5 but the DV is good.
I’m a recent owner of the Vero V with an LG G5 with a Denon AVR-X6800H.
I’ve performed a fresh install and updated via the command line to v4.9.269-88-osmc. I know there is a difference as previous my DV content was playing back fine though presumably in MEL mode (despite the content being P7 7.06 or P8 8.1) and after the update all of my DV content is now overly staurated and flickering.
If there is anything I can offer to help with debugging then I’m happy to do so.
Thanks for all that you do.
I’m only on 4.9.269-87 and I can’t see any upgrades for that kernel in the release repo. Did you update from staging, perhaps?
Hi Graham, all I did was apply the bullseye development instructions as per the first post in this thread and it updated to that version.
I see. Those instructions are outdated. Atm the ‘staging’ repo is in an unstable state. Let me check what you need to do to revert to stable. Stable now includes all the DV features that were being tested in this thread.
@GrimGriefer Try to downgrade the vero5-userland-osmc package:
sudo apt install --reinstall vero5-userland-osmc=1.7.0
sync && reboot
If this works, please, don’t apply any further update until you hear staging is in consistent state again. You should be now on staging without the DV FEL test stack if you updated before with the development apt sources.
Thanks for the updates Graham/Jim,
I’m not using the Vero in my main environment yet so I just reverted back to the 2025.03-1 build (4.9.269-80-osmc) and after manually updating it finished at 4.9.269-87-osmc.
I’ve been testing with these files and at the moment cannot see any diference between the MEL or FEL sources on either the Vero V of the Shield TV Pro.
I guess it’s just a matter of waiting for the FEL supported release in the coming weeks hopefully.
Once again, thanks.
You are comparing the Shield TV Pro which doesn’t support FEL and the Vero V which hasn’t publicly released FEL support, so that is correct you don’t really see a difference 
Hi would there be any possibility that Dolby could block this in the future
Or doesn’t it concern them
Thanks
Unless they know where you live and go to your home and take your device from you, then no.
The implementation has nothing to do with Dolby.
Hahaha I’ll make sure the house is locked down
