Try 7000..... see how that looks That's what i do on my A1OLED just now.
Thanks Gordon, much appreciated.

I think I just need to spend some time with it and grasp exactly what the various controls do, and what I'm trying to achieve. Unless it's through the display's onboard apps, I'm almost exclusively HD SDR. So I need to start watching more UHD Bd's and using the on demand apps, through the UHD BD player, to allow me to utilise the Pro's capabilities.

Looks like another update; they're like buses these with nothing for ages then two (almost) at once. :D

Lumagen

Beta 072019- HDR parameter changes (.ie Ratio, Shape, etc) were needlessly slow to change when being modified. Removed HDR Min Offset from menu. Please continue giving us your detailed feedback on issues via email at [email protected] .
Update time ~1 minutes @230k from previous firmware


Don't think I'll rush to update as it's nothing significant to me.

I watched Arrival this evening, my last viewing was before any of the DTM updates.
I loved the film but remember it being dark and difficult to discern detail at various points during the movie, well not any more, wow what a difference.
The murkiness was gone, the detail was in abundance and the orange bio suits just popped.

I expect most owners on this thread already know this, but there have been two more updates since the link I posted last week.

Quoting Jim Peterson:
"New release 072119 to fix issues with 072019.

Reason: 071919 has debug debug code left in which slowed down the menu. 072019 attempted to remove it but not quite right. So 072119 should complete the removal of the debug code".

Lumagen

Beta 072119- Same as 072019, but 072019 had an issue causing lockup in some systems. Please continue giving us your detailed feedback on issues via email at [email protected] .
Update time ~1 minutes @230k from previous firmware

I did the update to 072119 last night and did some tweaking of the settings following a post from Jim P over on AVS. I put 'Altered Carbon' on from Netflix, which is a typically dark program. I'm downscaling this 4k/HDR content to a 1080p TV, so it's not the best display to test on, but I have to say that this looked a lot better than when I originally watched this series and the darker scenes are easier to follow and some bright scenes really did seem to pop out of the screen. Should be promising for when I start using my X7500 in the winter. Who knows I might even get round to calibrating it this year...

I've had an issue with moire effect, from SkyQ, for as long as I can remember. Is there anything the Radiance Pro can do to eliminate it? The Q box is outputting 1080P50 at YCbCr 4:4:4. It can also be set to output at 1080i50 but, when I've used this in the past, it seemed to be worse. Granted, that was a while ago (years) and I probably didn't have the Pro set up correctly.

Is your display (if tv) set for pixel mapping, ie image is not zoomed by a few pixels etc?
Yes, always. I will double check this though as LG's name for this functionality is ambiguous.
I have used the Pro to move the image up a pixel or 2, as with some channels there's what looks like a slight underscan at the top edge of the picture.

The display is a 2016 LG OLED and the constants are it, and Sky Q. I'm wracking my brain and I don't recall the same behaviour when I had an LCD display hooked up to the Q box. I didn't have the Pro then either though.

They've updated the update due to some issues with the FPGA, now resolved. I hadn't got round to updating to 0800919 myself, so I'll skip to this one in the next few days, once I see a bit of feedback about it.

Beta 081019- Posted 082319 A new FPGA version from rev 080919 fixes issues seen in many systems with getting picture and other video issues. Software identical to 080919.

Can't help with that question Paul, sorry.

New update available, details below:
Beta 082219- Posted 090419 Bug fix for test patterns if output vertical top shrink is being used. Bugfix for restoring Alt-1.85 input aspect after displaying test pattern. Bugfix for Input: Options: Lipsync menu not being able to change setting. Added some more audio EDID format options under Input: Options: HDMI Setup: Audio EDID.

Another release up. I am now up to 082219 so happy with that and starting to look at 4K as useable. I have resisted 4K as every comparison until now has shown 4K just too dark or unrealistic. Finally it is worth watching and now it's close to 2K, but whilst I don't have my light meter to hand it still looks a little less punchy as 2K and using Ocean 8 (rubbish film but one I have watched and don't care about so a good comparison base) I still prefer to watch 2K. I am thoroughly enjoying 2K, still think I might be on the margin of brightness but enjoying 2k films. So far with my UHD 9000, Epson 10500 I don't think I have watched more than 2 film in 4K from start to finish.

Whilst the 4K version of Oceans 8 was watchable I preferred the 2K, as it :

  1. Seemed a little brighter
  2. Blacks were 'inkier' and the balance of shadow detail and shadow looked more 'right'
  3. somehow had more image depth
  4. Seemed smoother and more cinematic
  5. The colour palette seemed a little better
  6. I struggled to see any more detail on a 134" screen sat 11 foot away
As the 10500 is faux 4K and using the Panasonic and Lumagen offers an amazing 2K image, what can I do to get a better viewing experience with 4k, I am currently struggling to see why I should spend £20 on a disc when I am buying 2K at £5-7

By the way I watched Hacksaw ridge on 2K and the image quality was stunning

How do people set up the Lumagen for 4K HDR with the new software ?

I agree about the 2K verses 4K point. How much of it I wonder is what the Darbee is doing? I find that if I turn off that option there is a far greater difference between the two but with it on that difference becomes marginal at best with a good 2K version.

I have a Pro and a JVC N7. Very happy with 4K HDR here. DTM working a treat. Gordon did a full calibration when the N7 had reached 300 hours.

Surprised you're finding this. I now never watch Blu Rays with my JVC 7900 over 4k if I can help it. The lumagen and 7900 is incredible IMO, the best example yet was watching John Wick 3 last week, a few scenes actually made me want to reach for the remote and press pause, they have knocked the use of HDR out of the park with it!

Another update, supposed to be some great improvements with this based on something Kris Deering (on AVS) helped with I believe. I haven't even got round to updating to the last one yet, so I'll wait a few days to see what the feedback is and what tweaks are recommended to get the best out of it.

Beta 092019- Posted 093019 Replaced the DTM dynamic level (aka DLev) setting with a new more useful setting called dynamic pad (aka DPad). Added a new "adaptive" capability to DTM which allows DTM to adapt to light level changes between scene cuts. The adaptive feature can be enabled/disabled in the menu under Input: Options: HDR Setup: DynamicCtrls and defaults to enabled. Bugfix for DTM flickering issue. Bugfix for 2.40 input aspect with scale bias off was not as accurate as it should have been. Other small bugfixes.

I put this update on my Pro over the weekend and then changed the new Dpad setting to 3 or 4, from default as recommended by Jim Peterson.

For my actual light output of just under 60 NITs I put in the following values of MAX NIT 60 x 6 = 360 and then set the ratio control (left arrow menu) while playing a HDR disc. I set the ratio control so that the 'equivalent value' shows approx 2x my actual light output of 60 NITs, so in my case this was around 120 'equivalent value'.

I haven't run a full calibration on my projector yet with the Lumagen (just a more basic 2 point calibration in the projector itself), so there is no doubt more to come, but it's giving really good results so far. It's not as if I have excessive light output to play with either, but the DTM function seems to work really well to brighten up previously too dark content, but still allowing plenty of contrast and bright highlights really 'pop' too. :smashin:

Looks like two recent updates, I guess no need to do the earlier one, though I'll wait a few days for feedback on here/AVS before I update mine to the newer one.

Beta 100619
- Posted 101819
Bugfix for issue updating from 082219 and getting no picture with forced output mode selection via "menu 0874" command.
Added P3 colorspace to 'ZY46FC' rs232 command.


Beta 100119
- Posted 100819
A small improvement to DTM (dynamic tone mapping) that improves some scenes with low light levels.
A small fix for starting up test patterns via rs232.
Fix for the Output: Styles: HDMI Format: Rate Match menu not allowing changes to rate match setting.
Couple other minor bugs fixed.

Lumagen

Reading some posts on the MadVR thread makes me glad I've got this Lumagen...life is too short for all the faffing around that seems to go with using a HTPC: I thought it might have improved since the days when I used to run one (and spent more time fixing it, than actually watching stuff on it). I know these Pros aren't cheap, but find a decent used deal, do the occasional update and actually watch stuff on it seems a better use of my time.

Just a little update. There should be a new firmware out imminently with upates for a couple of things. One is to further finesse and optimise the, already stellar, Dynamic HDR tonemapping. The other is to get even more accurate colour fidelity within the tone map. It's the second part that has taken the extra time to get this out.

Also note that i have a new lumagen distribution website, link in my signature. Convergent will also be getting updated to new one later this month. I can be contacted through either.
