Increasing brightness made symptoms worse.

I have been struggling with headache from using screens for over 3 years. I've seen dozens of doctors and nobody seems to have any idea what is wrong. I have just found this forum and it is giving me hope.

I heard about PWM and it made a lot of sense. So I increased the brightness of my screen to 100% and downloaded IRIS to decrease it. After about 30 minutes it was horrible. Dizziness, headache, nausea.

What could cause this? And what are the usual first steps that you guys recommend in starting to fix this issue?

Tips to narrow down the issue and to find a monitor that helps?

Thanks a lot!

fusse What screen/display do you have? What does IRIS do? Is it similar to changing the white point on an iOS device?

fusse Iris is not going to help too much with the screen at 100% of brightness, this porgram is only a color overlay but you are still getting almost all of the led brightness power going throug the lcd screen to your eyes, it is a lot better to buy a flicker free monitor that features a minimal brightness or low brightness nits, you can check this by looking for monitor reviewers that mention the minimal monitor brightness in their reviews like techtesters channel in youtube or rtings, for me a monitor with 50 nits of brightness or below is the best.

Thanks for the reply. I have an old DELL LCD 24 inch display. IRIS let's you adjust many different things on the display such as blue light and brightness which they say happens without PWM.

Awesome! Thanks a lot for your reply. I'll look into that!
