Final Cut Pro 10.8.1 - problem with HDR videos since upgrading to MacOS Sequoia

Luis,

1) Correct!

2) If I mirror the Built in display to the external LG TV, it shows it in HDR! But it's less than ideal as it's not a full screen image. It's the Final Cut viewer with the rest of that info on the screen and the image I want to view is smaller within that frame.

I sent a bug report in to Apple via Final Cut Pro, I'm not a developer or have any betas.

I'm curious why no one is noticing this though? Does no one edit HDR on a laptop and output a full screen image to a large 50" or larger TV? The HDMI is right there on the machine so it's so simple to set up!

Thanks for the help everyone, I hope they address it soon in the next update.

Correct - it is still unresolved. I've installed every MacOS Sequoia update when they were released and just installed FCP 11, and the issue still persists.

Editing to add that I've spoken with tech support multiple times about this, but they don't have any updates. Last update I received from support was mid-October saying they don't have any updates, and they'd get back to me once they hear something from engineering. It's been two months have passed since Sequoia was release and the problem first appeared, but there are still no updates.

Thats simply not accurate in my case. Its down to the HDMI output from my Macbook Pro in FCP ONLY! The HDMI output works in HDR just fine (I use an HDR screensaver and it perfectly HDR, the monitor even says so!). But when i try and output HDR to that same monitor from FCP, it is not in HDR. So it's not the "non-apple monitor" as that monitor works in HDR just fine as an extended display, even showing lightroom output in HDR. It's down to FCPX output via that HDMI.

Same for me. From what appeared to be my final conversation with Apple support about this a couple weeks ago, they said because it's working fine with their monitors, the issue must be related to the monitors we're using, which is beyond their control.

As a result, I formatted my system and completely removed FCP, Motion and Compressor and installed another software title that I've been using at my job for the past several years.

Could you please share some screenshots that show your project properties and your Display settings for the system?

Also, could you specify the exact model of the computer?

The image on the LG from FCP doesn’t say HDR. How are put getting the FCP viewer into the LG monitor. It’s not mirroring the laptop. Can you make the LG mirror the laptop?

Don't you have to be a developer or on a beta track to have Feedback Assistant? There is feedback in the Final Cut Pro menu..

No worries. I wanted to have a look at Sequoia anyway so it’s installed on an external drive for now. I always wait a bit when a new macOS arrives in case of problems as going back to an older version is not easy.

Good tip to try, it does show on the LG in HDR when it's mirroring the desktop. Hmmm wonder what is going on that it no longer outputs HDR from FCPX as an extended monitor? I guess I should put in a ticket with Apple on this.

Tried to edit my post, but it wouldn't let me - I've spoken with tech support about this multiple times, but they don't have any updates. Last update I received was in mid-October saying they'd get back to me once they hear something from engineering. I reached out today for an update but haven't heard anything yet. It's been two months since Sequoia was release and the problem first appeared.

Thanks, joema. I'm not expecting much if any reply from Apple, as they kind of worded the email in a "case closed" scenario.

I somehow missed or misread AlainBE's post that said he was connected via Thunderbolt, so that shows it's clearly not a connection issue and truly could be "Third party monitors" as Apple support said.

It's been 2 days since I replied to Apple's email and no word yet, but I think the advisor is off on Thursday's and Fridays, so I may not get a reply for a couple more days.
