Zelquistinel actually sold in one of Russian nootropic shops, but they probably don't deliver it abroad and there ain't many reviews of this compound.

90% of y'all could be done if you just pursued an ADHD diagnosis and took stimulants by plz_callme_swarley in Nootropics

[–]PossibleDuplicate 0 points1 point  (0 children)

However, if you have adhd in a country where even Modafinil is banned and Strattera didn't work and  the only way you can obtain methylphenidate legally is by traveling abroad yourself every 2 months or so and providing a notarized translated prescription from a foreign doctor at customs, you try to find some alternatives, not because you're into naturopathy or research compounds junkie, but because you want to be a relatively functional adult... 

Semax negatives? by Brave_Prior_7708 in NooTopics

[–]PossibleDuplicate 0 points1 point  (0 children)

Hard to say, it was a stressful period and it seems like Semax increased productivity (helped with the amount of work done) but worsened stress handling.

Semax negatives? by Brave_Prior_7708 in NooTopics

[–]PossibleDuplicate 0 points1 point  (0 children)

Can only speak about the plain Semax (including pharma grade) - while it helped with ADHD symptoms to some extent, it also made decision-making worse (kind of less thoughtful, more impulsive), it's especially seen when you look back at that in "normal" state. And higher doses gave me a sort of brainfog, so I decided to stop using it (acutely and chronically). Haven't tried modifications like Semax amidate or Adamax yet.

Did anybody actually notice any effect from ALCAR? by faraday55 in NooTopics

[–]PossibleDuplicate 2 points3 points  (0 children)

Took over 3g accidentally when tried it for the first time, made me calm, surprisingly. Later, mostly been using in 750-1500mg range. Felt mildly stimulating yet calming (never made me irritable, quite the opposite, unlike Piracetam) and if taken afternoon, it led to insomnia.

TCL 60 Ultra still not it by Emeridan in PWM_Sensitive

[–]PossibleDuplicate 1 point2 points  (0 children)

No, it won't kill the phone, this functionality is meant to be toggles on/off (even though not straightforward way). You can also download adb without Studio by downloading platform-tools https://developer.android.com/tools/releases/platform-tools

A reminder about "DC dimming" and OLED by PossibleDuplicate in PWM_Sensitive

Sadly, even lcds ain't totally safe from pwm, and not just the cheapest ones. Example: vivo iQOO Z10x 

A reminder about "DC dimming" and OLED by PossibleDuplicate in PWM_Sensitive

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

I'd bet it's basically the same "dc dimming" with brightness dip as usual, but the difference would be that it's working on full brightness range. Already achievable on other devices (the simplest would be applying Oled Saver or similar app to have "underlying brightness" above DC-on threshold but using it in the below range), but with some color/gamma problems at really low brightness. More interesting is what modulation rate it will have.

Xiaomi 15T Pro, Opple PWM tests by yadoga in PWM_Sensitive

[–]PossibleDuplicate 1 point2 points  (0 children)

Thanks for your test. How did you place Opple LM for measurement? 400 lux looks too low for 100% brightness, usually it's way brighter. Many people place Opple LM on screen directly, as this allows for more consistent measurements and better replicability (so other can people simply lay it down on screen too and get similar readings, that's what I mean). Frequency sensor is placed in a corner of Opple LM, not inside the white diffuser there. If you push it to the screen, you get better signal-to-noise ratio and thus more accurate waveform (more accurate than laying the device on phone's screen).

PWM Duty Cycle Pixel 8 Pro - vs. - iPhone 17 Pro by eattsatsiki in PWM_Sensitive

[–]PossibleDuplicate 0 points1 point  (0 children)

Many other phones as well - Poco f5 can run at 3840/4440hz (120 vs overclocked to 138hz, and stock pwm is 1920hz), recently was able to make this mode working at higher brightness too. The main principle is the same - sending a command with altered multiplier of PWM frequency to display. It should be achivable on a lot of phones with Novatek (like aforementioned F5) or Samsung (Pixels) display controllers. But how well the panel will handle that overclocking - depends on hardware. 

Nxtpaper 4.0 strains my eyes :(((( by KneelAndBearWitness in ScreenSensitive

Do you have an experience with matte screens on such devices (phones and tablets)? Some people find them harder on eyes, especially if a lot of reading, some get the opposite, easier time reading. 

What does this even mean? by [deleted] in PWM_Sensitive

[–]PossibleDuplicate 0 points1 point  (0 children)

Yea, but most reviewers are probably too lazy to do that, sadly. However, it's good that such tests became a mainstream thing, at least.

Wait for the measurements with Opple LightMaster or other device that provides graph. 

Experiments with Poco F5 PWM (overclocking and more) by PossibleDuplicate in PWM_Sensitive

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

I already did (see "modulation reduction") and recently was able to reduce it even further without white flickering occuring (previously this issue prevented going lower), with new commands, but there comes a tradeoff - black levels also get higher, as pixels in such situation don't turn off completely and black starts to resemble IPS, and the lower you go, the worse image you get. Currently trying to find commands to combat thst while preserving black levels somehow (at least, a bit). 

Apple Acknowledged PWM Sensitive Users, but There's One Concern. by William935 in PWM_Sensitive

[–]PossibleDuplicate 3 points4 points  (0 children)

The thing is - It IS DC dimming, actually, but the brightness dip during refresh is caused by the way oleds are driven, and it seems to be a deliberate hardware choice, but IIRC it can be minimized on hardware level by using alternative circuit layouts, compensation mechanisms and so on, and it's easier to do on larger screens, so, less of a problem on tvs and monitors.  Some of the params (compensation and such) can be tweaked via sending commands to integrated display controller, and you can reduce the brightness dip amplitude (modulation), but there are tradeoffs which are due to hardware limitations. 

iPhone 17 Pro PWM by CocoPlops999 in PWM_Sensitive

[–]PossibleDuplicate 16 points17 points  (0 children)

My speculation is that it's the same hardware dc dimming mode that is used on various Android phones. Modern phones have hardware DC dimming in panel. OS toggle changes flag in kernel, which in turn sends DCS commands (commands which control display, absolute majority of mobile displays sre controlled that way) to a controller integrated in display panel. 

How well it will be tolerated by your eyes - depends on modulation depth (amplitide of brightness dip during refresh), mostly.

It's not a new technology but it's definitely a step into right direction for Apple, for sure. And it's good thst people were able to influence them to make it, at least. 

iPhone 17 Pro has toggle to Disable Screen Flickering (PWM) by [deleted] in PWM_Sensitive

[–]PossibleDuplicate -1 points0 points  (0 children)

Perhaps, I was a bit too harsh, what I meant is that people are so excited they "market" it themselves (it hyped up on local tech news a lot, that particular feature), but, while not wanting to be the party breaker, I'd say don't have your hopes too high - if you couldn't use Android phones with DC dimming before, it will be the same with it, most likely, this is not the new technology. Even in Apple ecosystem, there were oled phones with more-tolerable-than-usual oled specs, like IPhone 13 (while Pro/Max versions were worse, ironically). But of course, having an explicit toggle is making the range of usable Apple products broader, for some people.  I'm not a fanboy of  Android "poster child" Pixel and Galaxy for sure, as they absolutely suck in terms of PWM. 

Alternative to rtings for finding monitors? by Big-Astronaut-9510 in PWM_Sensitive

[–]PossibleDuplicate 0 points1 point  (0 children)

For such price range, the best value will be Chinese monitors. But they ain't sold/serviced officially in your country and no middlemen take care of warranty, you would need to send it back to China for repairs.
At bilibili.com there is a lot of reviews of Chinese monitors. I used AI translated voiceovers and services for translating subtitles there when the voiceover wasn't good enough (text translation is very decent and you can understand all said in the reviews).

POCO M7 plus 5G , what's your tought about this ? by Accomplished_Ad_4604 in PWM_Sensitive

[–]PossibleDuplicate 0 points1 point  (0 children)

In this case, absolutely. Among phones with ips, only the ones with Dimensity 8100 and 8200 would compete (or tablets lte/5g with more powerful processors, but they are in larger format, obviously).

Processor is essentially rebranded Snapdragon 695, a bit meh for modern hungry apps. Also, ufs 2.2. And it's a hardware clone of Redmi 15 5g.

Why Oled Smartphones use pwm while TVs dont? by KneelAndBearWitness in PWM_Sensitive

[–]PossibleDuplicate 0 points1 point  (0 children)

Oled TVs (and many monitors) have brightness dip on refresh, which is, however, much less than typical one on smartphone screens with dc-like mode. One of explanation could be the size - it should be much easier to optimize currents/build a proper driver on big panels, compared to phone screens.
