Oh so u can still see the outline of the scarf on the right, let me try with Disney + source when I get back to sg

On the YouTube source 1080p version I definitely can’t see the outline…

Will revert when I confirm again if the blacks are indeed crushed or it’s the source from YouTube

I think the black crush on @Ronildoq picture is just due to LG DTM. Below is Bryan’s previously posted picture with LG DTM off. It’s perfect :point_down:

Can see the texture of the scarf on the right perfectly. If compare to mine with MadVR on SDR2020 :point_down:

MadVR able to extract the red color on the right girl’s scarf, but tone mapping is similar and colors also fairly close (different phone cameras not withstanding)

So my conclusion is that if Bryan turns his LG DTM off, then it looks exactly like ours

Ya will pop by when we catch up again… currently don’t have any players connected to the OLED tv in bedroom, all source player are in living room connected to PJ…

Agree it’s very difficult to capture with camera as it keeps auto adjusting for darker scenes …

That’s why wanted u guys to check if the streaming source on YouTube is the same on your display? All the source used is different, one from Disney +, one YouTube, one bluray, and there is also the Tekno3d source…

Ya I can actually see that difference, there is a bit of red in the scarf, are these using the source from Disney + ?

Also how does it look on the election scene ? Using the same madvr settings for gamma and iris?

To lift the shadows here on this screen would sacrifice black levels and contrast in the process

Can u share the dark scenes + brighter scenes so we can have an idea how much contrast / black levels we giving up in exchange for the shadows seen here

Yes Disney+ Dolby Vision converted as LLDV through HD Fury with DV string at 1,000 nits then to MadVR.

Yes. I don’t change gamma and iris, but phone camera is sometimes wonky

Either you sacrifice black levels or highlights. I showed the test some guy did earlier that if you are on Cinema Mode with Contrast setting around 80, Iris 3 gives the best balance between highlights and shadow detail. It works for me.

It’s hard to show with a phone camera. I invite you over any night to observe and I can show you the effect of iris and since I bypass MadVR on another HDMI port, I can A/B between MadVR and no MadVR to show the difference. This lifting of shadows also affects texture and hair in bright scenes.

I got a very good result without MadVR, but having DTM off and LLDV with DV string at 100 nits. So using LLDV to compress highlights that are > projector nits is as effective as LG DTM, but since LLDV doesn’t crush shadow detail, the dark scenes are preserved as long as DTM is off.

I want to come too :innocent: Want to see new generation OLED with Calman calibration at infinitesimally small delta error. Also I think @Foodie has done the Calman shadow detail control adjustment so shadow detail should be best in class. Cannot compare…

Sure, come for drinks/supper. Ha… Night time best cos pitch dark n kids sleeping.

I skipped the optional shadow detail calibration step in my latest calibrations. Cos i find it raises blacks even if i followed the instructions. Blacks are more balanced when skip the SDC. AVS calibration gurus gave similar feedback too.

The SDC function was to fix black crush on certain oled models and panels which got high % of customer complained that LG had crushed blacks (like my C1. Some batches from factory had higher occurrence of crushed blacks). If got no crush blacks, dont use it as it will raise black floor and affect greyscale.

Dont raise expectations too high ya :rofl: From my naked eye, i feel it’s not perfect yet, esp black levels. But no time to keep recalibrating to compare due to 2 young kiddos at home. I just settled for a result with greyscale good de + skin tone.

Need to visit u too one day to see the madVR pq. It seems impressive! And i love SDR video more than HDR. More natural and pleasing to my eye.

Bro Bryan, this is the first time I actually take a serious look at this scene and something is not right with the skin tone and colors. Your overall image is very “dark” and “dull”. I’m not sure it is because of the difference in the source content - e.g. Disney Plus vs 4K UHD vs Tekno HDR or something else. But your image is vastly different from mine.

Lumagen Radiance Pro with DTM enageed

Or is that image you posted earlier originate from a SDR source?

Hi Sammy, that’s nice of you. Will arrange with you separately this week if u r in Singapore , so will pop by your place on one of the nights so we can catch up. Ill DM u separately . As u have mentioned and many have mentioned, it’s better to see it in person. I always enjoy seeing it at other places so I can make a decision on how to approach and strike a balance between shadows and contrast we see on screen. I’m slightly inclined towards having that contrasty look in the image but also don’t want to sacrifice shadows.

Yes, that is the best way to audition…sometimes screencaps can be limited by the camera and display capability to tell the “true” story.

Ya, I see this now… so this is the thing I wanted to see…

On mine it looks like this

The black skin on the lady looks much blacker. With iris down to 0…

So this area is where I can raise the iris to 2 to match up the light output and combine the hdr calibration to gamma 2.2 to get a brighter image…

I went with the above because my entire living room lights up with 135” screen , is a lot of light… when pushed to higher nits

Ok understand, thanks for sharing the image

Just so I want to make it clear…remember you shouldn’t sacrifice the fidelity of the image by blindly opting for a more “contrasty” look which impacted the overall image. The scene, in particular, is shot in “broad day light with a clear blue sky”. Your image MUST be able to “convey” an image that is from a bright sunny scene instead of an overcast.

I can see a bit of pinkish like red tint on the lady’s necklace, doesn’t look as white. Is this due to the camera ?

So u see this necklace as pure white or slide pinkish on your screen ?

It’s very interesting because so far, a lot of the HT kakis and folks i speak to, all “prefer” the darker contrasty image

I listed 3 different images



The first is the OLED , 2nd lumagen with jvc laser, 3rd is the Lg with DTM…


It’s interesting, as I’m seeing many don’t mind sacrificing not seeing the headscarf, they say it’s fine :sweat_smile: but they want the contrasty looks and blacker blacks to it

Looks like many “ prefer” the contrasty look

This is quite interesting … because when u have a client, he tells u, don’t calibrate it to the 1st two images, calibrate it to the 3rd … I don’t want too much light…

Sometimes it’s quite challenging, either u open up the iris for more light and suffer with contrast or u close it down and enjoy the contrast but suffer the shadows

This has been an eye opener for me as I collate various feedbacks from all… well worth the time understanding different people’s preferences

This is Bryan’s picture posted earlier without LG DTM

This is Desray’s picture with Lumagen

Desray’s is a little brighter, but they are not that different.

Hence, Bryan has the best of both worlds. He can choose to have his picture look like the rest of us or he can have the dark contrasty look by turning on LG DTM

If you are providing a service and taking client’s money, my advice is to do what the client desire regardless of what is reference or preference. It is a futile exercise to even asked which image is preferred as all involves in some kind of tone mapping which is dependent on the DTM algorithm of the display and in some cases, an external video processor like Lumagen.

I would prefer 1st the most, 2nd one seems a bit clip for highlight areas, not sure whether it’s due to camera…3rd one is too dark with loss of shadow details, I would strike for a balance between black level and shadow details, if I can’t have the best of both worlds.

I agreed with your take.

Well said. An issue though is that its quite difficult to get the contrasty look for a client unless he has a projector with LG DTM. Other systems can’t create that type of look. Neither Sony, JVC or BenQ

Personally, I never liked LG DTM. It worked incredibly well for super bright HDR movies like The Meg. But for dark movies like The Batman, some Harry Potter and the dark scenes in Black Panther, I found myself struggling to see anything. My initial solution was to use LLDV and turn off LG DTM. However, that only works for Dolby Vision titles. So, the final solution was MadVR.
