HDR Bug Impacts OLED iPad Pro, Apple Working on Software Fix

[arkitect]

For something touted as the be all and end all for digital creative work, this is an embarrassment.

Accurate colour display and management was surely one of the things on Apple's check list? No?

They'll fix it by dithering near blue - it'll introduce noise. That's how LG's fixed WOLEDs near black

They say its only happening on the 13inch pro. If i remember correct the 13inch has a lg panel and the 11inch a samsung. Maybe thats the reason its on the 13inch only.

 

[BorisDG]

I wonder why not all by Samsung. Their panels are better in general.

Apple told iMore that it is aware of the issue and is working on a software update to fix it.

I don’t think software update alone won’t fix it. This is likely manufacture defect.

Seeing as Apple says they are working on a software fix for it, it appears it will fix it.

🤣 Tim just keeps on winning.

*checks stock price*

Yep, he does.

Where did it say that? They mention all the other displays it doesn’t affect including the M2 iPad Pro 11. I didn’t see M4 11 mentioned.

Anyway, the issue is chrominance overshoot and is inherent in all OLED panels, especially those with white subpixels. Firmware can mitigate it. The fact that it’s happening on bright blue is not promising. The fix is to turn off the white subpixel on some material. There’s going to be noise, crushed colours, diminished shadow detail.

We don't see it on other Apple Oled displays because they've already tuned the firmware to add noise, crush colours, diminish shadow detail. This is why the Sony BVM-HX310 dual layer LCD monitor is the professional benchmark in video mastering and costs $20,000.

"Though it’s present only under very specific circumstances, the issue isn’t visible using the same footage on other displays — from an iPhone 15 Pro to a Samsung TV to an M2 11-inch iPad Pro to a Steam Deck OLED. "

Yes sorry, youre right. Thought they mentioned the m4 11 too. Well, im gonna give it a try tomorrow with my 11 m4.

Blue gate bug city is here already and they haven’t even been released to the public

Keeping my 2017 IPP another year it seems.

No to mention the new Sony BVM-HX3110, even more expensive but amazing.

Im a huge display and oled fan, so i hope the hdr bug isnt too bad or at least not on every device (and not on mine) and can be fixed without too many bad side effects.

Just curious. Is the issue just in the immediate area the arrow pointed to in the image or would the issue move with the image as it moved on the screen? That could imply two different issues - hardware and or software.

I waited a few months to order my M1 Ultra MacStudio and two Studio Displays and the early "issues" were no longer there.

An interesting tidbit was that within a short time after announcement, deliveries were out to almost two months on a loaded 11" M4 model. So perhaps there is not yet an inventory status on the M4 chips.... or displays.

Yes to the first question and firmware can fix it. Just going to be trading one glaring visual artifact for some less obvious ones. This is normal for all Oleds to have chrominance overshooting. The iPad's is just really extreme and unusually it's blue overshoot.

Good thing Apple waited years to do OLED in a tablet so they could get it right! 😂

If it only takes a firmware update to fix it, that would be great. I’m surprised something like this could get past testing.

What is this based on? Feelings?

Firmware updates are not exactly a new concept, what is making you “think” this is a manufacturing defect of the panel itself?

Tim heard how popular it was so he improved it to “51 Shades of Blue.”

Anyone have a link to a clip where this occurs ? Want to try it out for myself

"To see the issue, fire up Netflix and check a Dolby Vision stream of Stranger Things Series 3, Episode 5. Head to the 25 minute mark, a scene of the kids walking down a long tunnel, and check Joe ‘Steve Harrington’ Keery’s shirt."

[cbns]

isnt as bad irl and in motion than that still shot, simply because things are moving. But yeah,it’s there

 

[luy]

Did you tried it out with the 11 or 13?

I don’t think software update alone won’t fix it. This is likely manufacture defect.

I suspect its a calibration issue, possibly even only with displays sourced from a particular batch or processing plant.
