logixoul I shot all my displays with a slo-mo smartphone + microscope. They all show a pixel flicker that I wasn't able to remove in any software way (ditherig.exe, IGCC settings, switching OS's, disabling hw accel). So it's probably LCD inversion. Can LCD inversion be fixed in some way, or do I need to look for a new monitor that doesn't have it?
JTL Don't know much about the mechanics of LCD inversion but my assumption is that it's a property of both the LCD panel and the electronics driving it internally. I read somewhere that the issue is more pronounced with TN panels, so maybe other panels could fare better.
ryans I don't know the answer, but I have seen some very smart display people on https://reddit.com/r/Monitors.
Alyosha2001 I think it's in the quality of the display itself, specific it's ability to create closer module countervalues (I mean like +35,53V and roughly -35,53V) So yeah, our best bet would be to hunt for a good display
ryans Would an AMOLED screen have LCD inversion? This is an interesting read anyway: https://en.wikipedia.org/wiki/Next_generation_of_display_technology
JTL ryans Well no. LCD inversion is inherent to how most LCDs are driven. This isn't to say (AM)OLED displays don't have their own issues either.
EyeDiscomfortCertificate ryans LCD inversion exists, AFAIK to prevent Liquid Crystals from wearing out (by changing the voltage polarity every frame). Diodes in OLED, being diodes, conduct only in one direction, and they will wear anyways, so no inversion.
ryans JTL thanks @JTL. Searching the forum, I see my question was answered already previously: Seagull OLEDs are quite different to LCDs as you point out. One important feature is that they flicker at their refresh rate. A 60hz OLED flickers at 60hz because each pixel goes dark every frame as it updates to the new frame. I’ve never gotten a migraine from an OLED, but I do get headaches. I wonder if that’s because of the higher frequency flickering. Maybe if I get a 30hz OLED it’ll give me a migraine. Or maybe if I get a 120hz IPS LCD (therefore with 60hz inversion flicker) it’ll feel like a 60hz OLED and I'll get a headache instead of a migraine.
ryans JTL This isn't to say (AM)OLED displays don't have their own issues either. I believe some (if not all) OLED displays use pixel shifting to reduce burn-in; I wonder if that is a cause for some of us.
Allekss ryans Most OLED displays ( i mean 90% of them ) use PWM aka flickering which is also a trigger for sensitive users !!!
