Laptopmedia claims to do a better job than f.lux?



  • Hi,

    not sure if this is the right section to post.
    However when browsing for laptop reviews I came across that site called laptopmedia.
    Seems to be a bulgarian website.

    They have Display contrast measurements etc , which is generally important to me and they also test PWM flickering.

    Now there are two things that confuse me about this.
    First, they claim to filter blue light without giving the picture a redish tint. And they explicitly say that thats the thing that differantiates them from flux. see link

    http://laptopmedia.com/reviews/health-impact-of-display-blue-light-and-our-solutions-for-you/

    Secondly they claim to eradicate PWM, by blocking pixels? Not sure how that is supposed to happen.
    They sell these profiles for reviewed Notebook LCD Panels.

    Can f.lux please give a statement about this. I emailed that site about methodology regarding the second point and didnt get any more answers.



  • Of course they didn't reply. They are making nothing but bogus claims. When Michael and Lorna wake up tomorrow, I'm sure you will eventually see a good answer from them. They will probably laugh at these claims just as much as I am.

    Edit: What a joke: you have to buy one of their profiles. http://laptopmedia.com/laptopmedia-profiles-list-of-supported-laptops-and-their-screens/

    They just want to steal everyone's money.

    The latest Beta version of f.lux for Windows is never going to be beaten, especially when it's perfected and released as a final version to replace f.lux 3.



  • I hope a Laptop/panel that the flux team owns, is listed too. So they can check whats going on with the profile.


  • f.lux team

    This is pretty uninformed, both about science and about f.lux.

    If you want to talk about sleep and alertness, you don't talk about 443nm light, you talk about the "blue-green" peak response of melanopsin (~488nm, and a wide range around it). They are really far off here.

    f.lux has offered "soft" dimming (which helps with PWM) for 4 years now.

    They claim to reduce color temperature to 4500K which removes <25% of the effects of bright light. Of course you can use f.lux to do this too - you can choose any setting you like.

    It seems like they test displays for PWM, so that is nice because you may not want to buy a display that has it.

    But once you do, it's pretty hard to avoid: many models will make PWM when not dimmed at all, or the power settings will dim the display slightly, all the time, or Intel's drivers will dim the screen automatically when you use a profile like the ones they suggest. And as I said, f.lux's dimming will be equivalent in any case.
