PS4 pro and HDR color banding issue
It's either an issue with the source or an issue with the display. Since you are not using FBOs during processing, the only lossy step in the output path is the quantization, which happens twice once to bit, and once to 8 bit. If dithering doesn't fix it, I'd begin to suspect an issue with the source.
Does disabling hwdec solve anything? If I cast the movie, and play with the smartcast app, it plays perfectly. I'll test with hwdec, disabled. I'll also test in a different player, and see if I get the same result.
Actually, looking at your screenshot again, I realized that there are far worse artifacts than just the banding in them; specifically, it contains a lot of what I can only imagine is clipping.
You could try enabling --gamut-warning. Does that highlight anything? I'm narrowing it down. I have this line in my mpv. I shall experiment, further. Any suggestions? If removing that vf solves the issue then I can only imagine something in your platform's d3d11va implementation is insufficiently equipped to handle high bit depth video.
But you could try finding another play that lets you use the equivalent of d3d11vpp post processing and seeing if that also reproduces the same clipping artifacts? Ah, yeah I figured using PQ, that wouldn't be a factor? You've pointed me in the direction of my GPU settings. So I changed a few of them. Changing the input range to Full, made a big difference, but not completely solved it.Deals Amazon deals Bargain threads Classified adverts.

Thread starter Roaders Start date Oct 24, Tags 4k uhd ultra hd banding color oled tv. Roaders Standard Member. At the start when the frame was filled with billowing clouds I was surprised to see quite marked banding of the colors. I would have thought that at the pinnacle of current TV tech you should never see this.
So do we still get this and I am just going to have to live with it or is there something up with my setup? I have a worthy cable connecting the blu-ray to the TV. I did manage to get some pictures illustrating the issue but apparently you can't upload pictures here Bacus Distinguished Member.
Roaders said:. Trojan Distinguished Member. Has your screen been calibrated, if not get it done it will make a world of difference. Bacus said:. No issues posting pictures on this forum at all!!
Lastly i think you would do better posting in the dedicated LG B6 forum as you may get a wider response to your issue. Trojan said:. Have a look at my post here. I have a B6 and Oppo and this shows how changing the settings in the Oppo might help. Technikal Active Member. Depending on how bad the banding is and how old you tv is being last years model you may be able to get your supplier to swap the tv out with a replacement.
It sets the grey scales and the colour scales and more besides, I didn't do it I just watched as mine was done, can't remember all of the specifics. Lots of people who can do it properly can be contacted via this forum. I stand corrected. I clicked the image button and it only gave me options to post links, no references to the fact that images could be uploaded.To watch HDR movies and videos from online providers, you might need to change a few settings to get set up.
If you have a laptop with an HDR-capable built-in display, there are additional power-related settings for HDR because these displays use more power than non-HDR displays. Therefore, HDR is turned off by default when running on battery. However, you can change the default power setting if you want. If HDR is turned on when your laptop is plugged in and then you unplug your laptop, HDR will be turned off to help save battery power.
If you plug in your laptop again, HDR will be turned on again automatically. The display may appear black temporarily when HDR turns on or off after you plug in or unplug your laptop. The Battery options settings only apply to the built-in laptop display. If you connect an external HDR display to the laptop and HDR is turned on for that display, HDR will stay on when the laptop is running on battery—regardless of the Battery options settings.
As a result, you might need to do some things to get the best results when using your HDR display in Windows To have HDR turn on, do one of the following:. When you first connect an external display to a laptop, Windows will duplicate your desktop on both displays by default. Here are some things to try to fix this:.
This can cause undersaturated colors after restarting your PC. To avoid this, plug in your laptop before restarting it, or change the power settings to keep HDR on when running on battery. On HDR-capable laptops running Windows 10 Versioncolors on the built-in display might appear under saturated, over saturated, or incorrectly in other ways. This can happen when you have an external monitor connected to your laptop and your desktop is duplicated on both displays.
This issue has been fixed in an update to Windows see Microsoft KB for details. When night light is turned on, the coloring on your display might have a red tint and content might not be readable on it. Here is how you can work around this problem. For more info about night light, see Set your display for night time in Windows These issues have been fixed in an update to Windows see Microsoft KB for details.
On an HDR-capable laptop running on Windows 10 versionthe brightness level for the built-in display might change unexpectedly when battery saver is turned on. For example, one or more of the following things might occur:. As a result, the display brightness changes when battery saver is on.
This can occur for laptops that are HDR-capable and ones that are not. For more info about how to change the screen brightness, see Change screen brightness in Windows On an HDR-capable laptop running on Windows 10 versionbrightness might change unexpectedly if the power setting was changed to Do nothing when I close the lid.
When you close the lid and then open it again, the brightness setting will be the same, but the actual screen brightness might be lower.Jump to navigation.
Human eyes are capable of seeing many more colors than those shown by video displays currently on the market. In order to understand additional details about 8-bit vs. Color depth is also known as bit depth, and is the number of bits used to display the color of a single pixel. The number of color channels in a pixel depend on the color space used. Each additional bit doubles the amount of information we can store for each color. In an 8-bit image, the total number of colors available per pixel is Table 1 shows the possible number of colors available for each respective color depth.
As most computer and TV monitors on the market are still capable of showing only up to 8-bit content, on which the bit content is displayed by lowering the bit depth. However, the actual advantages of bit can be exploited in the following most common scenarios. If a content is shot in bit, there is a large margin of safety to not lose information when applying the required changes.
Otherwise, image processing with lower precision could result in loss of sharpness, contrast and other valuable information. If loss of information occurred due to changes applied to 8-bit content, this could leave fewer bits per pixel and cause a color banding effect.
Color banding concept is explained with an example below. When an image sensor captures an image and is unable to distinguish the minimal difference between adjacent colors, a problem of inaccurate color representation occurs.
As a result, the image is translated into a single visual pixel color value due to the lack of adjacent color availability. This pattern results in an image which has bands of color instead of smooth calibration of colors.
Color banding Figure 1 occurs when an image is captured without enough detail, but the same image is supposed to look differently in the real world. An uncalibrated display can also show banding-like artifacts. Figure 1 shows the difference between an 8-bit and bit image with respect to the color banding issue.
The image on the left was captured with an 8-bit sensor and image on the right was captured with a bit sensor. In the left image, the required detail was not captured and fewer bits implicate fewer number of colors causing the color banding effect. Whereas in right image, the same frame was captured with enough detail and transition between, so the adjacent colors are smooth. To offer smoother color transition between the adjacent pixels, the current color gamut is not sufficient and it needs to be widened.
A wider color gamut is introduced in the standard BT. Displays supporting the BT. The comparison between the respective color spaces is shown in Figure 2 which followsrepresents the CIE color space chromacity diagram. The X and Y axis show the chromacity coordinates with the wavelength of the respective color space shown in blue font. The triangle outlined in yellow shows the color space covered by the BT. The black triangle shows the BT. The HEVC standard is capable of enabling more sophisticated compression algorithms relative to its predecessors.
The Main 10 profile allows for a color depth of 8-bits to bits per sample with chroma sampling. The input input.The log contains only a reboot and starting the file in question. Third screenshot, also picture from the phone, you can see the banding issued played from the Vero although it looks a lot worse real life than the picture off my phone lQvhTeQqKSvDl9vjLSbw.
There was, but I connected the Vero directly for this test, as I thought that might be the problem. Would this post relate in any way? If I turn it on, I loose the signal. Your TV appears to also have a simulated UHD mode that it applies to regular content by default and this may be what your looking at. If you loose signal when you enable that it is likely because your going through an AVR that does not support it, or your HDMI cables are not compatible with the higher bandwidth necessary. I would surely hope they supply a good enough cable?
I am pretty sure its proper UHD though. Now something even more strange happened. Vero plays the video pattern seemingly better and more smooth, however, its cut the screen in 4 and only displays the video in the upper forth corner:. Yes, I already did that, with the same result. I also shared the debugging logs in my first post with this setting enabled. I may not have been clear. That is not a safe assumption. Yes, those settings from rtings I have used already, and adjusted the contrast and brightness specifically after this.
I saved the picture profile and used the exact same profile when playing the video off the TV, so I think that should be in order. Thanks for the tip. I have testet both, that I am sure of, however I may have made a mistake when I uploaded the logs by the looks of it then. I will double check when I get back home from work today. I will go ahead and order a new premium HDMI cable to see if this solves the issue.
If it does, this will surely be embarrasing for me.
So the Vero would then output an 8-bit signal, and the image would show banding.Home Discussions Workshop Market Broadcasts. Change language. Install Steam. Store Page. Global Achievements. This is due to the 12bpc output. It should be 10bpc but for some reason Nvidia doesn't have it as an option. Btw, if your sky looks similar the left image and with rippling effects, that's what I mean by banding. It's not using enough color shades to properly blend so you will get a warped effect on subtle changes in color.
It's very noticable in the opening cutscene on the white backdrop when you have HDR on but I believe that is due to the way they made the cutscene. Because in game it's much better. This chart shows what settings can be used. Either my TV has a bug with it or game devs are making the games specifically for in mind when they add HDR. Which, honestly, makes no sense considering the PS4 Pro defaults to Someone at Sony would have noticed that before releasing the system rather than rushing it to market Some models have it as an option that is off by default and must be turned on for each port individually.
I'm looking at you Samsung It also seems that HDR turns itself back on when you restart the game, even though it will say it's off in the menu. Last edited by BigCNuggit ; 24 Jan, am.

Think we all jumped on the hdr bandwagon a bit early lol. Got a samsung ks and its all good apart from gears of war 4 which looks utterly terrible. Somethings wrong with it because ive seen it elsewhere looking awesome and forza h3 looks great on the same set up. Tried messing with all the settings on PS4 and TV and still got it. Its bad on fog, blue sky like in the picture etc I'm assuming it's not my tv as I get no banding on Netflix in 4K. I have a Samsung 65ks You must log in or register to reply here.
