It seems like when I view hdr content (typically I see this on youtube, but have also seen it on some image viewer apps) it makes content insanely bright, but dims everything else, and then it flickers when I switch away from the HDR content. There _has_ to be a way to disable this... right?

I understand the benefits coming from HDR, but some creators use HDR wrong, just to pump up their videos so they look "better". When watching them in dark room with low screen brightness they blind me, because the screen suddenly gets very bright. example: https://www.youtube.com/watch?v=XeOfAN4NqGk "Optimize video streaming while on battery" is a MacOS setting that plays HDR content as SDR while on battery. It works exactly how I expect, making those HDR videos watchable when the screen brightness is low. However I can't use it when plugged in. What doesn’t work is Settings -> Displays -> Preset -> "Apple Display (P3-500 nits) as that’s still too bright in a dark room for my needs. I am hoping there is a kind of system flag, private or documented API or other way to override this setting even when the MacBook is plugged in. But I do not know how to find How can I always force streamed HDR video to be presented as SDR on macOS even when powered and not just on battery power?

I have a m1 max macbook pro. I'm not sure if this is a bug or a software compatibility issue, but whenever I view HDR content the screen windowserver takes up 100% cpu and the increase of brightness of whole screen along with the decrease of brightness for sdr white is not synchronized, resulting in very noticeable stutter / flashes. While I try to research around the issue, I came up with this option that should disable EDR, so at least I won't get this performance issue on my studio display. However, when I click on the check box nothing happens - it's still checked. Does this suggest a bigger problem with my system? Is there a way to set this via the command line?

Currently screen shots are coerced into standard color ranges, meaning you cannot take an accurate screen shot of the screen when ultra bright HDR content (or possibly ultra black HDR content) is shown. Is there any solution for this, at present?

I have a new Mac Studio and am having troubles with it and my monitors' HDR. How do I force it to recognize and properly output an HDR signal? Before I got the Mac Studio I had both of these monitors connected to a PC with an Nvidia GTX 1080 Ti which was using them at their full resolution, frame rate, and HDR - so they definitely do actually support it. It connected to the left monitor via DisplayPort and the right via HDMI. My **right monitor** is the ViewSonic VP2785 (4K60, HDR, AdobeRGB). It has DisplayPort and HDMI inputs. When I connect it via HDMI, I do not get an HDR option in Settings. I can set resolution (which is "More Space" i.e. native), color profile (AdobeRGB), refresh rate (60 Hz), and rotation (standard). When I connect it with a USB-C/DP to DisplayPort 1.4 cable, I get and use the same options. However, when connected this way, it frequently doesn't wake up when the system wakes up, so I prefer the HDMI option. HDR never shows up. My **left monitor** is the ViewSonic VP2786 (4K60, HDR, AdobeRGB). It has USB-C/DP, DisplayPort, and HDMI inputs. When I connect it with a USB-C/DP to DisplayPort 1.4 cable, I get and set all the same options as above, but I *do* get an HDR option. However, when I turn it on, I get a very washed out display - not HDR. When playing HDR content, I still get the usual dirty contrast areas where the brightness saturates non-HDR colorspaces and gets clipped. When I connect it with the native USB-C connector (with a thunderbolt-compatible cable) I get the same as above, but as with the previous one it often fails to wake when the system wakes. **How do I get it to recognize and properly output HDR?** How do I figure out why it's not working in the first place? Some other notes: - This behavior was the same on 15.0 and 15.0.1. - When it "fails to wake", OS X agrees and has moved all of my windows/spaces to the other monitor. When I power-cycle the monitor OS X will then move all my windows/spaces back to where they were across the extended displays.

On [this Apple support article](https://support.apple.com/en-us/HT210980) , it seems to say that the MacBook Pro introduced in 2018 or 2019 supports HDR on its built-in display. However, for what I understand, MacBook screens are not bright enough to support HDR. I also have not seen any HDR settings on my 2020 MacBook Pro, nor is HDR touted in Apple's computer specs. Do MacBook screens support HDR?

When I'm scrolling through reels on Instagram, every now and then (becoming more and more frequent) I will come across a video that slowly turns up the brightness a considerable amount (at night it becomes truly painful). The like and comment buttons (which are white normally) will slowly become desaturated gray colors. I'm assuming this is because the HDR video is overlayed with SDR content so it looks desaturated in comparison. Here is an example video that this happens on: https://www.instagram.com/p/ChlmNv4D-i2/ (view on newer model iPhone in Instagram app) This phenomenon happens to me and a lot of people I have asked, however it also doesn't happen to people with older models (iPhone XR does not seem to expereince). But, when I look up what iPhones support HDR playback, it says iPhone 8 and later. So I'm wondering a couple things: 1. Is this phenomenon called "HDR Playback" 2. What phone models support this annoying "feature" 3. Is there a way to disable this? Other people on other forums have said turning on lower power mode disables it, but I was wondering if there was a more proper way? I get that this can be useful for artists and pro videographers and the like, but when this HDR colorspace stuff is done on amateur videos it gets super annoying because they are frequently just overexposed and it hurts my eyes.

I'm quite tempted by some 4K HDR external monitors that are slated to come to the market soon. Question is - can a Late 2016 MacBook Pro drive 4K HDR monitor at 60Hz? 4K monitors are supported as per Apple doc, but it doesn’t mention HDR at all.

There was an article > Windows 11 is getting true HDR desktop wallpaper support and better > screen casting Are HDR wallpapers supported on macOS? If yes which version? Can it cause burn in issues?

I am trying to increase the brightness of some SDR photographs so that they can fully utilise the brightness of "XDR" displays on apple devices to display a bright image (For example, screens on some apple devices can reach 1600 nits peak brightness for showing HDR contents). In gimp, after importing an image, I set the "Image -> Precision" to "32 bit floating point", and "linear light". Then I increase the brightness. While it does look brighter, I am not sure how can I make sure I get the 1600 nits (or at least, say, 1000 nits). When I export the picture to .hdr format, and look at them in the Preview app, the colours looks completely different from what I see when I am editing in Gimp. **What should I do to (1) use the full brightness of the displays and (2) get consistent result when I am editing and after I export?** If it is not possible with gimp, please feel free to tell me what other software should I use (for example photoshop?). I think this should not be difficult, because there are plenty of tutorials online about how to do this for **videos**. But when I try to search for how to edit **photos**, I do not get an answer. **It would be helpful if there is a link to a tutorial on making HDR photos.** **Note:** by "HDR photographs", I mean image formats that could be viewed with more than, for example, 1000 nits of brightness, and extremely high contrast, on supported monitors, **just like HDR videos**. I am **NOT** discussing the technique of taking multiple photos of the same scene and combine them into one.

I can view beautiful HDR content on YouTube (as long as the video is labeled 'HDR') with my Late 2021 16" MacBook Pro using the built-in Liquid Retina XDR Display. How do view my own photos taken with my iPhone X (Camera set to take photos in HDR) on my MacBook Pro with the same level of contrast?

While playing Youtube HDR videos on Chrome, bright colors are abnormally too bright and causes a loss of details in bright areas. For more information about this issue you can see the posts below: - https://www.reddit.com/r/applehelp/comments/mcselq/color_problem_on_macbook_pro_16_2019/ - https://www.reddit.com/r/chrome/comments/jk7g8u/chrome_macos_not_displaying_youtube_hdr_content/ Is it normal for everybody? I there any way to overcome this problem? As of now I can't see any other way to play Youtube HDR content on Mac. There's no Youtube app on Mac, and Safari does not support HDR.

I am watching same video on a Mac and two phones, iPhone 12 and Android. There is abnormal glare on the Mac. For example in attached pics the Mac shows too much glare on girls face, clothes. This happens when I play [this video](https://youtu.be/2RIDhA9c8qw?t=10) in HDR in Chrome, it does not happen if HDR not enabled in Safari. How do I solve this problem ?

After upgrading macOS to 10.15.4 on my Macbook Pro 2018, an HDR option shows up for my 4K BenQ PD3220U display. It is even pre-selected. I can tell that the display is definitely in HDR mode. Unfortunately it does not look very good. The fonts are weird, as if they aren't antialiased. It is especially noticeable in black-on-white text. Is there a way to improve the HDR mode? The display is connected through USB-C. Changing resolution to Default for display does not help. I have used this display in HDR mode with ChromeCast Ultra so I know how good HDR can look.

How can I get macOS 10.14 on my MacBook Pro (15-inch, 2016) to output the macOS UI (desktop) in HDR mode to my Samsung Q6F 4K HDR TV display? I'm using a USB-C/Thunderbolt to HDMI 2 dongle and an HDMI 2.0 certified cable. Also, the same Samsung Q6F 4K HDR TV when connected to a Windows 10 desktop seems to operate in HDR mode. i.e. Windows 10 switched to HDR mode and videos (youtube or separate video files) also appear in HDR. Am I missing a macOS setting? Do I need an update or a new dongle? --- System info

I'd like to set my (iOS7) iPhone's camera to always default to HDR **on**. I do enable HDR when I'm taking pictures, but it always seems like the iPhone forgets the setting and goes back to HDR off.

I have the iPhone Xs and I’m interested in the Smart HDR feature. I note that it is enabled by default. However, only a handful of the photos that I have taken over the past week or two have the HDR icon. If I disable Smart HDR and take a photo before and after manually activating HDR I don’t get the icon overplayed on the resulting photo. It definitely looks like the HDR is working but I just don’t understand what the icon means.

Amazon Prime video came to Apple TV today. Amazon Prime video supports Dolby Vision, but does it support it on Apple TV. I ask because Amazon Prime video doesn't support all Dolby Vision capable devices. In my case I have an Apple TV 4K.

I got to see the whole keynote at September 1st and assumed that iOS 4.1 would bring HDR to iPod Touch (4th gen) and the iPhone (3Gs and 4). Today I got my iPod Touch and I don't get it, where's the HDR button? I get that there is no flash (was announced), but HDR Button should be there, right? Did I wrongly assume that iPod Touch would have HDR?

does anyone know a good tool to create HDR photos on OSX? Freeware or paid? From Windows I know: - Photomatix Pro - Picturenaut - FDRTools any hint?
