anyone?

Hi, I also own a XPS 13 9320 Plus OLED. I don't understand technically as you do, but if you send me a link of a youtube video with HLG HDR I can try in my laptop and let you know what happens...

I tried one HDR youtube video, when I right click it (statistics) I see "LXb3EKWsInQ / KGZJ VMK1 5AR6", which I'm not sure whether it's HLG or PQ HDR as you said. Another video I played here the stats said "tO01J-M3g0U / C4QV 7D4B NENE".. they both worked fine (at least to my standards).

BTW, Dell released in the Drivers website for XPS 13 9320 an update for the OLED panel: (the previous download file didn't work properly and now Aug 8th they reposted it)

I'm not sure if that solves your issue. In my case, my panel was already the latest and the update was not necessary.

Well, I update to the latest version but it seems nothing changed. None of the issues (HLG video and color profile) are resolved. Sad. The color profile issue make this device is not suitable for content creation like photo editing and video editing under SDR mode. For example, by switching from SDR to HDR, my wallpaper become less saturated which is more accurate.

thanks for your reply Lolato. First you need to turn on HDR in windows setting, then ensure the youtube video is displayed in hdr by checking the icon. Right click and go to statistics you will find HLG or PQ under "color". Feel free to check these videos.

Hi there. Thanks for sending those 3 links (youtube). When I right click on the video and choose "Stats for Nerds", I see many items: such as "Video ID; Frames; etc"... If I look in the color line (as you asked), all I see is "Color: bt709 / bt709" (for all 3 videos). I Can't see any "HLG" or "PQ" in any line of the statistics...

As for the HDR, actually it was off. I now turned it on in Windows, but I couldn't see any significant difference while playing those 3 videos (my impression is that HDR off in windows makes the video even a bit more "vivid" in color) (I'm not an expert in colors, so my description might not be professionally accurate).

2 more things:

1) It's important to note that I'm using Windows 11  Build 22622.450 (beta release)

2) I'm not sure which icon you mention that I was supposed to look for (when you wrote "ensure the youtube video is displayed in hdr by checking the icon")

Thanks for your reply Tesla1856. Please check my photos comparison between the iphone 13 pro max and xps 13 plus oled, both in youtube with HDR turn on. The dove image is hdr in PQ, so the displays on iphone and xps are identical. All the rest images are taken with the video in HLG, where the display on xps is distorted, overexposure and oversaturated, some area are so bright that losing detail. the display on iphone is correct, a more vivid display compare to sdr.

I think it is because Dell or Intel (the integrated graphic)don't have the correct LUT for the HLG HDR content. My friend's desktop with Win11 is showing the correct HLG HDR content under HDR mode.

I hope to upload another group of photos showing the comparison between the video displayed on SDR and HDR on XPS 13 Plus Oled, but seems my image upload already exceed the limit, so maybe later. But the above images should have explain what I mean.

I like YouTube and much as the next guy (even rip/capture some videos from there) but I don't think it's the best place to be getting videos to test this level of quality and performance. Seems like there would be some specific "reference videos" that you could use (also download for local playback (not streaming)).

Hi lolato, please check my reply Tesla1856. And for the HDR, you should see "smpte2084 (PQ) / bt2020" or "arib-std-b67 (HLG) / bt2020" once the hdr video is displayed in youtube. bt709 means the video you are checking is in SDR and your HDR is not turned on. If you open the video first and then turn on HDR in windows, you need to refresh the video page.

The icon I mentioned is the button in youtube you use to switch the quality, if HDR is enable, there will be "HDR" showned on it and the video quality you can choose will all have HDR suffix. Otherwise, it will only showing "4k" or "HD" on the button.

Hi there. Thanks for your patience and explanation of each step. Indeed, I needed to refresh it after switching HDR ON in Windows. Now I can see the HDR icon (as well as Color in stats show either PQ or HLG). And I confirm my XPS 13 OLED has exact the same behavior as yours (PQ plays beautifully. HLG is overly saturated, which makes much better to watch when HDR is switched off in windows).

I tried to play some HDR content in Netflix in order to check if Netflix uses more HLG or PQ color. In my test with about 4 different shows with Dolby Vision feature (I'm assuming that's how I see in Netflix if it's a HDR content) (I tried shows such as "Our Great National Parks"  and "Moving Art season 3".... (just because they have beautiful nature scenery). In my test they all played beautifully (without the oversaturated image we saw in youtube). Does that mean that Netflix predominantly uses PQ color for HDR?

Thanks for your reply and new input Lolato. I don't have Netflix subscribtion so I cannot verify that and I remember the information (video spec) provided by Netflix is too sketchy, they don't even allow you to manually adjust the video quality but judging by your internet speed. Dolby vision should be HDR and the quality of "Drive to Survive" is pretty good, but I cannot tell whether the one playing on Netflix is on HLG or PQ.

And to be honest I don't know how PQ and HLG actually works, I just found the common spec of the corrupted video. I also tried download the HLG video from youtube and play them with win11 built-in player and potplayer, they looks fine. So I think it is because the LUT applied to youtube online video is incorrect.

Hi there. I decided to do the same test as you (download the video from YouTube in order to check how it would play). Actually I was more interested in knowing whether it would play in HDR quality or not. I downloaded this short 4k HDR video from beautiful colors in Costa Rica (PQ color):

https://www.youtube.com/watch?v=LXb3EKWsInQ&list=PL9bdXp_75aSsSRJDVRMA72tbE_nSOnt8Y&index=2

I downloaded the highest resolution version - aprox 1GB - (through both atube catcher and TubeDigger). To my surprise, when I download and try to play (either by PotPlayer or Win11 new Media Player) it doesn't play with HDR capabilities. (I can compare in real time the quality and brightness of them both with the one playing in Youtube. (In Youtube I can clearly see that the HDR is enabled, not only by the label underneath the video, but also because the brightness and the color is gorgeous... Whereas playing both in PotPlayer and Win11 (although still beuatiful colors) it doesn't seem to be playing in HDR mode... (even though of course my Win11 is set to HDR now, as I could see it working in Youtube). Are you sure that when you downloaded and played in PotPlayer it was really playing in HDR mode? How can I know if it's playing in HDR or not? Anyway that I can force that to happen? Thanks

Actually I realized that potplayer probably didn't play the video in HDR mode, more like SDR, but at least it seems normal (no overexposed and saturation). The win11 movie&TV has better and more vivid image, but still I cannot say it is definitely under HDR. So when playing HLG video, youtube streaming, win11 movie&tv, potplayer will give me three different performance. 

And I learn that windows doesn't natively support HLG video. However, at least the HLG youtube streaming on other system is within expectation, on xps 13 plus it just horrible. I also tried connect xps 13 plus to external hdr monitor, it won't help. I'm not sure if that's because something related to codec.
