Good find! They look awesome too.
I believe appliance/fan bulbs are also available, such as here: https://www.bulbs.com/product/40A15C? I understand an LED bulb might melt in an oven, but I don't really understand why a fan can't use an LED, too much movement?
(I have not ordered any and can't vouch for any supplier -- just passing it along.) My local HW store apparently sells GE Edison Bulbs.
Has anyone tried these? https://gist.github.com/hanksudo/33ddf24f27f403c00b746b6f12bde746
WhisperingWind Visible changes only occurred after modifying the i915 code
It'd be awesome if you could share what you changed (and how you compiled it).

intel_reguseful, there's a thread about Intel graphics dithering registers + Linux here: https://ledstrain.org/d/1017-registers-to-control-intel-graphics-dithering-on-linux-located/17.chintamani_reverse @chintamani_reverse Which features did you disable?
Unfortunately I'm forced to Win 10 22H2 (IT mandate). And the dizziness is back
@DisplaysShouldNotBeTVs Do you still use this setup?
I am happy on Win 10 21H2, but will be soon forced to Win 10 22H2!

I also purchased one. Interestingly an incandescent bulb (US power) shows 'high risk' (no symptoms):
While my corporate HP EliteBook 840 G6 with Windows 10 21H2 shows 'no risk' showing a white background and I do get mild symptoms:
The device does not seem very precise as I sometimes get very different measurements. I would only begin to trust a median of many measurements.
Win 10 21H2 OS Build 19044.4170
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?
Well, Windows 10 21H2 which has been working fine for me, will be EOL'd by June and corp IT will force me to Windows 10 22H2 in a few weeks.
jen I wish I had a great answer for you, sorry to hear this.
Most practically I wonder if you could find a better sleep-shade goggles that totally block out everything, and have someone assist you, such as a blind person would use a "sighted guide".
jen that I can't do video visits for healthcare anymore without severe injury.
Also wish I had a better answer. But blind people do use computers succesfully with screen readers (programs that literally read the screen), such as VoiceOver on macOS / iOS or NVDA on Windows. One of the best computer programmers I know is blind. It's a learning curve but could pay off.
DisplaysShouldNotBeTVs Of course, the current 2022 Intel Windows driver also has forced color management and temporal dithering too, even with ditherig.exe.
This could be an interesting research point if this could be validated with a lossless capture card.
Dizzy Did you try to disable Windows 11 ACM?
photon78s I just tested a Mac Mini M2 using my 240fps cam/microscope setup and I can confirm I see flickering even when Stillcolor is enabled.
This could be PWM or LCD Inversion or something that's not temporal dithering. See @Seagull very insightful post here.
jordan So my friend tried still color on his MacBook air m1 2020. He has a Boox Mira eink monitor connected to it and you can see how it flickers but then when stillcolor is enabled (dithering off) the flickering stops.. BUT when he moves the cursor the rest of the screen still flickers? Is that some sort of SW flickering or is that the nature of Eink. Check the video below (there's sound too of him explaining it) https://imgur.com/a/r9kT9uq
Awesome stuff. The mouse cursor effect is also discussed in this old thread about using a Paperlike screen to detect dithering.

DisplaysShouldNotBeTVs and would love to provide any info I know that would help in creating an Intel version
@NewDwarf has a technique here for disabling temporal dithering on Intel Macs and also AMD (it's different technique than the one linked by op). I don't believe it was tested with a lossless capture card but some have reported success on Intel Macs.
DisplaysShouldNotBeTVs There's two layers of dithering on XDR Macs
one at GPU level (which Stillcolor does disable) and one at display panel level (which it can't disable)This is interesting and unfortunate. It's hard to imagine two separate temporal dithering algorithms look good on a screen even to "normal" people?
