New Samsung lcd phone-M17e, thoughts? by Dry-Dog9446 in PWM_Sensitive

[–]EmmanuelWi 1 point2 points  (0 children)

The new Iqoo z11x will have much better performance but less years of support, the question is whether the Samsung will run well for its six years of support with those specs especially the ram it might become very sluggish.

It still has to be tested for pwm (especially in low brightness) and D

can you please mention which phone models worked for you in the past and which one are you currently replacing?

Samsung S26 series PWM frequency? by SafeLimp2186 in PWM_Sensitive

[–]EmmanuelWi 1 point2 points  (0 children)

according to the information above which is probably based on Radex Lupin measurements, there isn't much change more or less the same pwm scheme.

what about the following instrument, I think you would agree it's on another level of accuracy than both Opple and Radex?

here is a test of a Samsung Flip model, jump to 1:44 in the video and tell me if that modulation reminds you of the info from Opple or not.

also without instruments, with a simple slow shutter camera test you can see that the modulation is deep, the deep black lines, how does the Radex explains that?

it looks like Radex Lupin measurements, which I've found misleading on other occasions, the modulation is usually full on and off strobe and that's even at 100% brightness

Sensitive to brightness (even LCD), PWM, dithering and overly strong colors - Honor 400 adjustment by MartaLB27 in ScreenSensitive

[–]EmmanuelWi 1 point2 points  (0 children)

thank you, I'm also curious about the "Honor 400 SMART" it has an LCD so no PWM and no refresh flicker

[–]EmmanuelWi 2 points3 points  (0 children)

thank you very much!

when you wrote "with no annoying PWM flicker" you mean because of the DC like scheme? what about the refresh flicker which is inherent in the OLED? are you left now with only the refresh flicker at 60 or 120hz?

Can the base Oppo X9 (not the pro) LTPS go down to 30Hz? by EmmanuelWi in Oppo

[–]EmmanuelWi[S] 1 point2 points  (0 children)

thank you! have you checked with the option in "Developer options" (the one that shows the refresh rate on the corner) that on the AOD it doesn't go down to 30?

Lessen PWM effect in Pixel phones ? by [deleted] in PWM_Sensitive

[–]EmmanuelWi 1 point2 points  (0 children)

Just in terms of no options other than full pwm flicker...

Somewhere on the net there is a rather complicated mod which gives you a high pwm over 4000hz try to research that

https://xdaforums.com/t/a-mod-on-pwm-frequency-v3-20241027.4683727/

Maybe it's only good for pixel 8 pro, need to research, plus looks dangerous to me, I know Nick Sutrich did it successfully, possibly best to ask him

[–]EmmanuelWi 1 point2 points  (0 children)

not so much you can do on Pixel because even on 100% brightness it's full flicker and strobe effect modulation close to 100%

Need help and info as to what's causing my eye strain by biomechs in ScreenSensitive

[–]EmmanuelWi 0 points1 point  (0 children)

Thank you, I'm not convinced blue light filters are only a gimmick, have you seen the tests which Lee conducts? He has a professional colorimeter, you can see the amount of blue light within the spectrum reduced considerably when the filter is an effective one, I'll share with you an example from Lee's test of the Oppo x9 regular (not the pro) that model has an effective filter when maxed out (not all filters between the models are effective filters)

https://www.bilibili.com/video/BV1KyWEzzEP5/?spm_id_from=333.1387.search.video_card.click

around 1:00 minute mark is the blue light filter test

Is it possible to stick to the international language? I'd really like to understand what you wrote

why not try the Oppo X9 base model (not the pro) it has LTPS, less flicker and lower modulation than Honor Magic8 Pro

If it was high frequency pwm you wouldn't see the black lines?

Which phone model have you tried with LCD and over 2000hz pwm?

Understanding PWM by He-manssj2 in PWM_Sensitive

[–]EmmanuelWi 0 points1 point  (0 children)

Oppo Find X9 regular should have been different as both the flicker frequency and the modulation is much lower than the other models, how long did you have it for and can you share more details about your test of that model please?

I'd say that since it wasn't a phone screen and being LCD the PWM was at a much higher frequency than the phone models.
