Hi guys generally I have no strain on eyes. I use laptop and PCs with ips screens so no pwm, but in Windows OS I have pressure on temples, similar to migraine. What's the trigger? Thx a lot

@"DisplaysShouldNotBeTVs"#p33470 Hi on win 10 2004 Laptop with 2060 but dithering is off because I use color control app . Thx a lot

@"Aquila"#p33487 Can you elaborate on that color control app?

Migraine on temples : what is the trigger in windows OS?

ryans

DisplaysShouldNotBeTVs If it's 11 22H2 or later, is Automatically manage color for apps enabled in advanced display preferences? If so, turn it off, having it on causes Windows itself to intentionally generate temporal dithering.

Just wondering if you know if this is true for Windows 10 22H2?

Aquila

Any suggestions about trigger.

Does the setting "Automatic color management" really disable temporal dithering? I have tested that on Win11 but it did not work for me. I use ditherig.exe on Windows. So maybe that could be an option for OP.

Does disabling ACM help you on its own?

Aquila Can you elaborate on that color control app?

Aquila

I use Win 10 only. Color control installed and dithering disabled.
Nvidia control panel: 8bit, RGB, full.
Win 10: 1809
I tested the dp cable and today the HDMI cable.
The hdmi seems better for migraine.

I tried it all. In Windows 11 neither color control nor ditherig.exe really eliminated dithering.

I had to go back to Windows 10 21H2.

Aquila No one knows for sure. My leading theory on the culprit is DirectX 12, specifically DirectWrite an DirectDraw. What they are doing to cause the symptoms is unknown

ensete is DirectX 12

I suppose, directx 12.2 - ultimate is the issue.

At least rtx20+ gen use 12.2, safe 1660s and gtx10 gen use 12.1 ( no complaints at all )

last iGPUs ( intel arc, ryzen 610m and newer ) - also use 12.2

Reinhard62 did you test dithering with a capture card, or it's all about eyestrain feeling?

I have a notebook with Ryzen 7Pro 6850 and Radeon 600M graphics.

Aquila

Update:
RtX 2070s + Win 10 1809 17768.1098 + colorcontrol + no migraines
Intel Arc A770 le + Win 10 Ltsc 2021 (21h2) + terribile migraines.

Hp Pavillion with 1660ti (ddr6 Samsung) seems very good on Win 11 24h2 (no migraine)

I suppose the GPU isn't the only trigger, something hide in the OS is the main cause.

What colorcontrol settings do you use in the safe one?

Now I switched to Rog 1080ti.
Nvidia Drivers 528.02
No more colorcontrol app. Dithering is disabled by deafult on 1809 + 8bit on nvidia control panel
