Completely same.. I am an Engineer and programmer ,and after 10 min. on the page I was suspicious about myself , if I am an idiot not to find a TEST ??.. Good to know I am not alone.. There is no “TEXT TEST” on the page to compare this
results : https://iristech.co/wp-content/uploads/2018/05/pwm-flicker-types.png ??

Forget about “Testing 123” text , I am just looking for the moving line (first iframe not the yt videos) and again comparing it with the lines in the : https://iristech.co/wp-content/uploads/2018/05/pwm-flicker-types.png
Result : Again None of the patterns , look like my pattern , I see 2 ghost lines moving with my original line with 1,5 -0,8 mm offsets (left and right of the original respectively)..
So what ?

I agree with TJ and others, about the needless confusion engendered by this piece, and you have failed to address any of those comments. To be precise: this article lacks clarity. In particular, after your text “If your monitor doesn’t use PWM you will see a smooth moving line like this” you have a picture of a thick white bar that blurs into blackness. Which I don’t think represents a moving line at all and is not something that I see. There is no test for the text images displayed either. So why are they even there? Please review.

In reply to Patricia. Hi Patricia, To set the brightness on your monitor you need to look for the button on the monitor itself

Where did the GIF versions go? Is it possible to get them back as alternatives to the Youtube video, please? The video display seems to have some problems on my computer, it’s hard to clearly see if it flickers or not. I remember viewing this page earlier when it had the GIF versions, and they were displayed fine.

How do you set the brightness on the hardware ? Where is this tool located? Please advise. Thank you in advance. Patricia

Hello,

I think there might be something wrong with this test page.
It says “Bellow you can see a white line moving really fast.”. But I can’t see any moving white line at all. I can only see the example still images under “What to look for?”.
There is, however, a seemingly miss-placed text reading “PWM test” far to the left of the text reading “We will use this to determine if your monitor has PWM flicker….”. I’m guessing the test is meant to show up here?
Tried 3 different browsers. All show the same. No moving images except the eye GIF.

Hi Theresa,
You can follow the explanations on the page as to how you’re supposed to view the lines and whether or not your monitor has PWM flicker
What you use this test for is completely to your choice 🙂

I could not follow at all what you were trying to teach. am I to view all these lines as they appear now on my computer? Are you trying to sell me some program or just help me know how bad or good my computer is for my eyes?

My old desktop monitor just died. We need to get another one and set it up with Iris. Can you tell me which monitor you would buy if you had to get a new one? We want to get the best possible one for eyes and then add Iris to make it perfect.

Also, are curved or flat screen monitors better for the eyes?

Thank you!

(We’re in the U.S., if that makes a difference re: availability.)

This makes no sense. Both on max brightness and minimum I see the single lines moving. Nothing changes.

Additionally, the software does not dim my computer when on automatic and health. I think there’s a bug in the software and I am also confused on the above!

In reply to Iris (Team Member). After some research I found that it is moire pattern effect caused by something like difference between monitor pixels and particular camera pixel scanning system. Sorry for inaccuracy describing the issue. I do believe that there's no such effect if you are not filming the screen. Am I correct?

In reply to Ramos. There are some very rare cases, depending on your monitor, that Iris will not remove absolutely all of the flicker, it also depends on the settings of Iris that you have, so it's possible

Привет из Москвы! Спасибо за ваш труд!
Now working experience is much better without that flicker but there’s still some weird color blinking being noticed via phone camera… Do you know if that’s ok?

Can you try to follow this short video on how to remove flicker with Iris?
https://www.youtube.com/watch?v=ZBn_3OynGBA&list=PLYgsC6pUhQFpDMsoxDQQgZYaikOFzevw6&index=19

Additionally, you can also do the test while using sleep mode, it will also help

This is a short video on how to do it:

I am not sure to understand where is the test. Is it the UFO test with just a line moving, or is it something with that text? Because I do not find anywhere that test with the text…
About the UFO with lines, the line, even at max brightness, doesnt appear to me as a totally clean line. Which means, it either flickers at max brightness, or it doesnt and I see multiple lines because of something different (no, no LSD).
I have tried to slow down the line and it became a clean line and it is a clean line also at min brightness.
So I am confused. Does my display I have PWM?
According to Notebookcheck this display has PWM at 200hz. I would like to have a more effective testing method.
You could include one in the app…

In reply to Jan O.

Here’s what I would recommend:
1) Remove PWM Flicker:
https://www.youtube.com/watch?v=ZBn_3OynGBA&list=PLYgsC6pUhQFpDMsoxDQQgZYaikOFzevw6&index=19

2) Pick a low enough blue light value that’s also comfortable with you
You can try Sleep type which has 0% blue light but it’s really red and might be a tad hard to look at your screen
If it’s not comfortable for you, you can try a higher value

You can manually change blue light values like this:

I’m using IRIS full version since last December, and do far I can tell the difference from before. Mostly my eyes can tell ? Less eyes strain for sure and more concentration on things I work on. Thank you!

Very cool. I just tested this laptop –
It appears to use DC dimming vs PWM.

Erm, what does it mean if the line stays the same like in the first image (Original) ?
