Can any owner please comment on the playback of 4k hdr atmos mkv files from network devices such as a nas? Thanks
I shall have a check later today, although I don't have Dolby Atmos set up.

Edit - Via Plex DLNA it comes up saying that cannot play audio as it is not supported, whether this is because I do not have Atmos I have no idea. It won't even let me switch the the 5.1 DD audio track when the Atmos track is muxed in. Other than that, playback works flawlessly 4K video with AC3 5.1 and the HDR Optimiser works too.

Running standard settings for HDR on my E6. This display is much much brighter than the previous OLED I owned so I do think it's down to each display.
I did test BvS where I could see more detail in brightest highlist with optimiser on.
I was more impressed with the player's presets like the Light Environment that made the picture brighter without breaking black levels (during daytime viewing anyway).
Also the HCX processor is performing very well. But for optimiser I would say very few selected scenes will enhance my experience as it is thanks to the capabilities of the display.

What display /display setting are you using though? I'm not disputing your subjective impressions, I am just wondering whether with many TVs (and the default display setting on the player) the luminance is probably high enough that most scenes look okay regardless; the human eye is not very (or at all) reliable as an objective measure. I wonder whether an objective test would reveal differences in peak whites in different scenes, or if you changed the display type in the player...

That's interesting. That is my impression as well, except in my testing the adjustment of the dynamic range (ie. the presets) seems linked to the display preset of the HDR Optimiser as I have needed different settings for the same movie to acheive a watchable 'exposure' when switching between HDR optimiser display types.

Does anyone on the thread have a 4k non hdr/Wcg pj whom also owns the 420/820? Just wondering how effective the optimiser is, currently own the 900 (had it since release).
I just got the 420EB yesterday so just had a quick play I don't even have a 4k projector yet (hopefully soon) so obviously the HDR settings are not applicable but I have noticed with a little tweaking in the settings the image from 4k movies is improved over the xbox one s
I am impressed with it so far the reason for the change was the xbox seemed to struggle with some titles mainly imports like star trek it was also pretty noisy this seems to be cured also but more testing needed. The thing I find quiet strange (not complaining) is how much improved the image is on a 1080p projector compared to standard bluray ok colour & brightness is a bit of a battle but with this player you have settings to help with that on the xbox you had nothing. For me I am perfectly happy with the cheaper player so far its exceeded my expectations and with the money I saved I picked up a nvidia shield on an Amazon warehouse deal so lots of new toys this weekend :)

Dan takes some beating on his deals without the usual sales patter you can get from others.

My UB-424 has found my local Plex server...

It works well, but seems to play movies at 60p rather than the 24p that my Apple TV Plex app streams at. So the Apple TV4K remains superior for local streaming, as expected.

UB820 fan is always on compared to my UB700 which comes on at power up and then promptly shuts off. It thus appears the UB820 lacks the thermostatically controlled fan which was in the UB700/UB900. Close up it has a nasty whine. :(

It's also audible at 2m (just) with no audio on in an open stand. It fails my Lawrence of Arabia silent audio test (the well scene with first appearance of Omar Sharif) as rather than being completely silent there is a slight bit of fan noise audible, my UB700 passes this with flying colours.

Mine plays back at 24p. Have checked the settings for 24p playback?

I'm looking at 'silent' PC fans to replace the one in mine. I'll do the one in my Radiance Pro at the same time. That one sounds like an F35 coming in do a landing.

You have a noisy UB820 fan too?

Unless things have changed there are no silent PC fans in that size. I tried and failed with my Toshba XE1. Solved it in the end by disconnecting the fan and taking the top case off :thumbsup:

Although this fan looks good at 12.1dB if it fits Deep Silence 60mm Ultra-Quiet PC Fan, 2000 RPM
But measuring the UB820 fan, it looks more like a 50mm which has a very restricted choice with the lowest at 23dB from that site.

Noisy fan on mine as well although i only hear it close up
I bought the 820 because of the reported fan noise on the 420
Could have saved £150 if i bought the 420
plus using a Dolby Atmos demo disc it seems far slower in playing back each demo clip compared to a UB700
Further feedback to follow

My UB820 is completely silent. Would need to put the ear right next to it to hear the noise. The UB900 made more noise.

"silent" and "noisy" are quite subjectively used to be honest. I'd put my 820 on the silent end whilst playing (you can hear that very short whir when it seeks a new position after a chapter change). It is certainly quieter than my projector now which is pretty quiet too, so I can't hear it playing a film.

I sit about 1.5m away and it's in a wooden cabinet with an open front but closed sides and back. It also has my BD35 on top of it ;-)

If I had something to measure noise accurately for you guys I would!

For what its worth I don't have an ear for music but I am extremely sensitive to "noise" (as in something which doesn't fit)/buzzing/fans so I am very easily bothered.

Yes but in all honesty, with the remotest amount of background noise, it disappears. I class myself as particularly 'sensitive' to noises, it drives the wife mad when I'm taking a new car apart to fix squeaks and rattles that she can't here! :D

Looks like a 40mm fan to me and there are a few that can be classed as quiet these days. I found a few Noctua fans that are as quiet as 14.9dBA at 5k rpm.

If I was to do it, I'd figure a way of slowing it down, to make it even quieter.

If it's a 50mm, our luck isn't in I don't think.

Not good news regarding fan noise.
Don't get me wrong, it's not excessively loud. I've measured both the UB820 and UB700 at 29dB start of UHD disc and 28.2dB at a quiet section where the spin speed is lower. But I think that is possibly as low as my meter goes as I get almost the same reading with nothing running at all.
(Un)fortunately my ears are more sensitive than that or just I'm more sensitive to the frequency of the fan :(

However from moving player around to check fan operation I've found the audibility of the noise changes. So may be one of these frequency vs angle things where the ear hears more at one angle than another.
Noisy fan on mine as well although i only hear it close up
I was thinking mine may have been a one off, which I might have been able to get a better one by replacement instead. But if that's the common position it makes the choice now to return for refund or not.

Especially as HDR Optimiser ON or OFF seems to make no difference in the viewing so far.
Setting UB700 and UB820 to identical B+W Gamma/B+W tone curve, DRA and brightness settings the results are pretty much similar whether optimiser is on or off. Transformers The Last Knight on LG E6. Perhaps once it's dark I'll see something more. Or maybe the optimiser is another thing to be added by firmware update...;)
If you build it they will come :)

I'm hoping the fan might bed in, or as already mentioned move it slightly
I must say the adhesive they used to stick that popup cardboard advertising onto the top of the case was a bit of overkill I had a bugger of a time removing it
Still early days only spun it for half an hour

Might be wishfull thinking but it sounds quieter to me already. I'm putting hours onto it while I do other things in the hope the fan bearing might bed in a bit. The other thing I was thinking of is to add some closed cell foam etc behind the player as the fan is fireing at a hard wall for mine.

But how much more did the thermostatically controlled fan of the UB700 cost vs the UB820 one? Pennies, a pound or two? Don't spoil the ship for a ha'p'orth of tar...:(

Good call on that. I was thinking about adding some inside, when I open it up but, am a little concerned with reducing the air volume by doing so.

I suspect the UB820 is 'doing' more thus the fan needs to be on all the time. The speed also changes, to be much slower, when playing Blu-ray, which would back that up.

Another new feature is the player can now output SDR/BT.2020 with all the HDR controls/settings (except DRA changes to DRC). Player info shows 2020 output and TV is in a non HDR mode showing 2020 is input. Which is great if you want to play a UHD without HDR enhanced grain on a HDR TV. On a quick look at Bridge on the River Kwai UHD, grain is much less in your face.

Edit: And Starship Troopers school scenes. Although if you want the enhanced grain back and the over hot contrast just turn tone curve (white) to -12 :eek:

Edit 2: And the infamous crawling Black Ants grain in Crouching Tiger Hidden Dragon is gone too :smashin:

Except fan is also on when playing CDs...
Are you sure you're not mistaking the air noise from the drive for the fan?
Drive speed also slower when playing blu-rays. And apart from HDR Optimiser what are the new players doing that might need more processing grunt/produce more heat than the old ones which managed fine with the fan off...

Could be. I just hear it being less loud. Will investigate further.

Apart from the HDR Optimiser... You mean where the machine is performing the HDR tone mapping? :)
The latest HCX Processor may just run hotter too.
I'll take the lid off tomorrow and take some pictures. It looks like the fan is a 50mm jobby too so I'll have a look for a quiet one and fan speed controller.

After configuring my Radiance Pro correctly, I've further adjusted the Dynamic Range control to reduce it to +2. Post Radiance Pro re-configuration, the HDR image was just too bright and I noted some mild posterisation with a specific scene and cloud rendering. Will continue to play when I have the time.

May be a basic question but does the 820/420/320 play the content's native refresh rate?

Bit of poor design if it did. Everybody else is managing to produce SOCs which don't need active cooling. Later tech should mean cooler tech.

60-->50mm isn't too large a jump. Just would mean some of the fan output would be hitting the case, a bit more turbulence etc but I'd take 2,000 rpm over 5,000 rpm as there should be less noise overall. For the ultimate go for an overhead 140mm fan. Just need a dremmel and the will to cut the hole in the top...

For discs yes. 24p is 24p
For online streaming unknown as there are no streaming apps available yet. But on previous Panasonics eveything was output in 60hz even if 24p Netflix etc.
Over DLNA/via USB: Don't know.

Which other player(s) is doing onboard tone mapping? Bar the Oppo.

Eff that! I can't be bothered with modifying, especially as the player's reliability is still unknown. It's OEM+ or nothing! :D

The fan is a 50mmx15mm with PWM control (3 core cable). It can be seen here:

There's quite a lot of room in there and the size of the power supply board would suggest it's different, at the very least, to the UB420 >. Nice heatsink in the HCX Processor too.

I think you're right about the drive noise. I'm 99% certain it's that I hear and not the fan after all. :facepalm:
