I don't have the unit but I've seen other players with a similar eject slot.

Checked my player, it has the two slots underneath! not sure why I couldn't see the last might! on the right hand side there lever looks to have a little hole or dimple, which you slide to the left.

Still can't understand why I couldn't see them last night. Funny thing I checked my other player and couldn't see them, so I will have to check that!

Glad the OP got their disc out.

The UB450 also has the slots

They are very easy to miss. Panasonic really should have included it in the manual. I imagine it's mentioned in an internal service manual, but they need to print it in the one that comes in the box.

I still think the Blu-ray elves made the holes in the night. I even checked the underneath under a lamp. What's weird is I checked my other player and I couldn't see them either. I bet those naughty elves were busy again.

Anyway glad I brought it up, even if I couldn't find it!

Is there a list anywhere that logs the peak nits for different 4K Blu-ray discs? It would be good to know when I should have the HDR Optimser On or Off. I have an LG CX, so I don't think I should have the HDR Optimser turned On for any movie that peaks at ~700 nits or less. I use the info button on the remote when playing, but often they have no info on there regarding the nits.

No need to do that. If you choose OLED, the optimizer doesn’t kick in until approx 1000 nits anyway. Anything below that will be untouched.

I have a LG C9 as well as a Panasonic 820. I use a weird method for how I watch my films, but I feel it seems to be the best way to watch an HDR10 movie on an LG TV prior to the LG OLED 3 Series.

What I do is keep the HDR Optimizer set to "On" at all times but have it set to the Super Luminance Setting (1,500 nits). The reason for this is that I feel like the C9 does great with tone mapping the image up to about 1,400 nits or so. I also have my Dynamic Tone Mapping on my C9 set to "On" as well.

Now, as most people know LG's Dynamic Tone Mapping Setting overcooks the picture, making it way too bright at times. So to compensate for that, I go into the HDR Options Menu on the 820 and set the Dynamic Range Adjustment slider to -6. This in turn lowers the overall brightness of the picture, revealing more highlight detail that was blown out by LG's Dynamic Tone Mapping Setting.

The reason why I set all of this up like this is that I noticed that LG's Tone Mapping by itself is relatively dimmer than other competitor OLEDs (Sony's and Panasonic's). But with these settings, I can get a brighter picture that dynamically changes without the issues that is brought by LG's Dynamic Tone Mapping setting. Mind you, my set is calibrated so these settings could look different to you or anyone else. And these settings are not 100% perfect by any means. None the less, I feel as though I don't need to worry about turning things "On" or "Off." I can just sit back, relax, and watch my movies.

So, I encourage you if you want to look at these settings and try them out. But it's your TV and you can do whatever you want with it!

Got this today to try out Dolby Vision and MAN is it a slow player compared to my cheapo LG. Feels like it takes forever to do anything.

Long shot: This is for anoher panasonic player, check underneath if there is something similar on you player.
Looking at some other models, it could also be small slider inside a tiny slot which should be pushed in one direction.

That's what happened with mine, so the trick would not have worked since the tray was already sticking out almost halfway, as was the disc once I pulled the tray all the way out.

Good to know should it not eject at all in the future.

The chap working on the software mod noted that the player does a lot of stuff in the background that isn't needed, so if he can get it to work it should speed things up quite a bit. Really we should have an option to go to a Disc Only mode for our players, we don't all need Apps running in the background.

My Google TV has an "apps-only" mode that disables all the personalized content recommendations and just lets you choose from the inputs and whatever apps you've installed. I don't see why a peripheral device like a Blu-ray player couldn't implement something like that, especially now that 9/10 times all that smart/internet functionality is going to be redundant, unless you've gone out of your way not to get a smart TV.

Wow! I never knew all the apps are running in the background. So I guess I’ll be better off (somehow) if I uninstall my Prime, Netflix and AccuWeather?

They are as far as I know, not sure how much uninstalling them will improve performance, not sure if it's even possible? The chap doing the mod found a kernel bug which takes up 50% of the CPU, so that will probably be a bigger benefit.

I’m assuming they can’t run if I don’t have the wifi connected?

I'd imagine they soft-start when you turn on the player, so they drain some resources to speed-up their start-up.

I do that same with my 55oledbx and 50qn94a as I share the ub820 between them. Leaving the optimiser setting on at 1500 nits and then the tvs doing their thi ng is convenient for me.

Mine's not connected to the internet, never has been, never touched any of the apps. Will they still be running in the background regardless? Hmm.

Yeah, I'm not sure if it's even possible to uninstall the default apps on the player. I tried looking for an option to uninstall them and there isn't one to be found.
