Zootopia in 3D, hilarious.

Thank you all very much for your input.

Is this why at least until the 50's B&W film could achieve deep focus in a way color film couldn't?



Not relevant from a technical viewpoint, but the different comparison sets brought this to mind, a development that had to wait until the late 20's to become implemented in a really major way.

But yeah, I think my camera did have an actual B&W mode now that I think about it, desaturation is clearly not the way to go, and hopefully not the way the aforementioned mode goes about it. Have to check the manual again, think I previously just ignored this aspect as I had no intention to ever shoot in B&W.

You can test it, take a challenging photo. Take one in colour and the other in b&w mode and then put the colour one in your photo editor and try different settings to see which one looks like the one from the b&w mode shot.

Hi
Has anyone tried playing 4K HDR Blu-ray \ remux movies (50-80 Mbps) from MadVR on the integrated graphics of a desktop CPU? is this possible? Is everything okay? Can you please write what CPU \ cooling you used and how hot it gets?

[steppi]

For the past few months I have had the problem that while watching a hdr movie with tone mapping, strong flashes show up. I attach a video, does anyone know how to help me?

yes that is possible why would you care about temps of an iGPU?

lower your settings considerable you are dropping frames like crazy.
if that doesn't fix it my best guess is flicker protection but i have barely any clue about tone mapping.

I know it's stupid but I'm afraid of liquid cooling systems
Thank you!

use air?
avoid intel newer iGPU may have insane trouble with DX9. there are terrifying reports from that driver...

a 5500gt should be able to do that with ease.

Close to pulling the trigger on a LG G4 — has anyone had any issues with MadVR's auto resolution switching on the G4? I'm asking because...

The second bug causes the occasional black screen when changing resolutions and refresh rates frequently in a short period of time. The only fix for this is to unplug and re-plug the TV in, but this is unlikely to happen with real-world usage.

I'm doing around 10-20 display mode changes per day and this would be a total deal-breaker if I couldn't use it.

Yes, I would like to build it air-cooled
Okay, thank you very much!

If you want the best air CPU cooler that will fit in pretty much any case I would recommend nh-d15s. That's the one I got and haven't had any issues, cools very well and is quiet with a big 140mm fan and 6 heat pipes. I don't think there is a model that cools better and will fit in any case

Unless they fixed the black screen when switching from/to HDR it's a pretty useless feature still.

I was thinking about him too, thanks! )

Could you elaborate on this issue please? Are you talking about a madVR issue or a Windows issue or an LG issue?

[strumf666]

Sorry, I misread, I thought you were talking about this:
https://www.hdmi.org/spec21sub/quickmediaswitch
This feature is flawed, because it doesn't work when changing to/from hdr.
Madvr auto switching should not be influenced by the display tips, model or make.
It can be affected by os/driver/player.

[tp4tissue]

This is why Tp4 uses AMD for movies. Fast/ Flawless HDR switching at least on S90C, can't speak for G4. Did have the G3 briefly, it does black screen if you do it alot, but you'd have to do it alot and you can get it back without unpluging if you have hotkeys set to switch resolutions. In any case, Tp4 can't recommend WOLED under any circumstances due to washed out colors.

More color is something so intrinsic to image quality, you just can't "make due" with less, it doesn't make anysense that you would do that.

Gamut is critical, and woled just looks pale.

I don't mean this maliciously or as a put-down but it possibly might be worth getting an eye exam for colour blindness. It could be that you have some kind of partial low level of colour blindness or desensitivity might be a better word than blindness. I have no idea how the eye testing works or if it's valid, for example if we look at rtings G4 review it shows all Delta's under 5 for HDR, but this result could be bogus if they aren't measuring delta at full saturation levels, just as LED bulbs colour rendering index is bogus cause it looks at desaturated colours and the huge delta errors on saturated reds get absorbed by the low average delta of all the other colours. So if they do something like this for eye exams then the result could be invalid too.
The vast majority of a consumer grade LED bulb look absolutely disgusting to my eyes and nobody else seems to be aware of this so I guess that's what you're experiencing with OLED TVs as well so I definitely get where you're coming from, I am not dismissing what you are seeing with your own eyes.

All I can really say is for me looking at the G4 in person doesn't give me any reason to think the saturation is lacking. The C4 and B4 I absolutely can tell the colours degrading due to the viewing angle limitation — but you said you had G3 MLA panel so that couldn't be it on your case. For me personally the MLA panel for viewing angle stability of hue and saturation is an absolute must have, that is why my only choice is between G4 and S90D. Not even Bravia 8 is good enough for what I'm after. I can see that green cyan shift off axis and I do not like it. I have no idea how anyone watches VA panels either, they are totally unacceptable to me. And yet they are still on the market for 15+ years and selling in large numbers, so the only explanation can be "unit variance" in the human visual system and this I contest is what you are experiencing with WOLED panels.

Edit : also what is the room lighting conditions in your living area
Do you use a bias light? 2700k or colder? I have a Philips hue behind my screen at 80% brightness 2700k.

Edit: and blood tests can be worthless too, they don't check for everything properly, I had vitamin b6 toxicity for a year cause the standard blood tests simply don't pick it up, it was only once I got to a specialist did they check for b6. And you can get false positives for vitamin B12 levels if you eat seaweed but none of the B12 is bioavailable so the testing is all bogus.

Re: The VA panels, it isn't because of variance, it's mostly because people aren't experts and just buy based on price and size and this tends to lead to lack of options. You can't buy a new plasma because they took them off the market. Likewise, if they decided to only start manufacturing TN panels then this is what people would buy because they don't have a menu to choose from.

I think the market is going to start entering a manufacturing consolidation shift soon. It wants to move to OLED and the fact that OLED wears out is desirable to them. Doesn't really make sense to make OLEDs along with all the variants of LCD panels with all the variants of backlights like quantum dots, etc. I figure VA will be one of the first to go because for TV use IPS has wider viewing angles and gamers moved to TN for faster response time.

[flossy_cake]

@ tp4tissue, it could also be the wider spectral distribution of WOLED that isn't jiving with your vision.

But Sony are switching back to VA panels for their flagship — https://youtu.be/Y8M8Jt3N7Ms — this I find confusing

I hope you're right because a high quality IPS can actually be pretty decent in my opinion. I was actually considering the Bravia 3 LED which uses an IPS in some of its sizes because it has 1864:1 native contrast which means for my 120nit peak brightness I'd be getting 0.06 black which is the same as my current Samsung plasma and should look completely fine with my bias light setup. But it's motion processing is shit for gaming, 60hz only, lots of response time smearing and the frame interpolation is janky. But colour accuracy looks fantastic and it's mega cheap so I'm still considering it. Wish they would use IPS in their Bravia 7, but no.

Is Samsung QDOLED more resilient to burn-in than WOLED? Rtings burnin testing reports their S95C was "surprisingly resilient" to burn-in compared to the other WOLEDs, but I don't know whether to believe that is generally true for QDOLED as a technology. This could be the tipping point that makes me choose S90D over G4 as 99% of my use is HTPC + MadVR and I'm concerned about dropping a bunch of cold hard cash on the G4 and dealing with burn-in down the line when I could drop less cash on the cheaper S90D and avoid the burn-in issue and get the super duper saturated colours for HDR. But then this TV repair guy is saying Samsung quality control has gone to shit - https://www.youtube.com/watch?v=bYpuILVtmfQ - and I dont know what to think
