ensete I think I am using the manufacture color profile. Below is what I have for my office computer. I will double check it for my home computer later tonight.

    ensete Here is the ICC profile for my home computer. It is from BenQ too.

      That is the correct ICC profile. Mind doing a test for me? Remove the ICC profile and see if your symptoms return. You can easily add it back

        ensete Test it for about an hour, there is definitely a noticeable difference. After removing the ICC profile, my head does not feel good.

          ensete Would you please let me know how to add the correct ICC profile back? Thanks.

              So using the manufacturer's icc profile helps to reduce eye strain. This is god to know. But it does not get rid 100% of the eye strain, right? That means there must be something else that is (still) causing us eye strain.

              Can u try one more thing? For Monitor driver, try using Generic PnP driver instead of the manufacturer's one. See if that helps. Here's how to do it:

              Control Panel -> Device Manager -> Monitor -> select monitor and right click -> Update Driver Software -> Browse my computer for driver software -> Let me pick from a list of device drivers from my computer -> Generic PnP Monitor -> click Next.

              When I use the Generic PnP monitor driver on my laptop, I do noticed a very noticeable relief in eye strain. It's like the eye strain is significantly reduced. When I switch the monitor driver back to the Lenovo's driver, I definitely feel the eye strain more. When I switch back to the Generic PnP monitor driver, noticeably less eye strain. Can you give it a try and see if it has any effect on your eye strain or not?

                Kray This is interesting. I am going to try it out. It seems that driver and color profile are two independent things. I just switched the driver to generic pnp, but the color profile remains to be the one from manufacture.

                  Kray hmmm... tested the generic pnp driver for about an hour. It did not improve anything. It actually seemed to make things worse. Probably need to test it for a longer period of time. It may be that the generic pnp driver is good for laptop, but not for desktop?

                      Hmm...that's interesting. Yeah, maybe it works for laptop better, i dont know. Can you share the specs of your desktop? The laptop that i use to test the generic PnP driver is a lenovo T440p laptop, Windows 7, integrated intel graphics.

                      On my desktop computer, (which thankfully i get no eye strain) i am also using generic pnp monitor driver for my benq flicker-free monitor. My desktop is on windows 7, nvidia GTX 760.

                          Kray The desktop I used for the test is Dell xps8910 with windows 7 pro and nvidia 750TI graphics card. The integrated intel graphics card is disabled. I think I may need to test it for a longer period to make a definitive conclusion.

                            Jerry Sorry, yes it is not simple. You can't add it back using the "Add" button, that would make too much sense, once added it will appear in the list you can pick from in the All Profiles tab. Sorry about that. But informative you found a difference

                                ensete I used the disk that came together with the monitor to get the manufacture icc profile back. Yep, it is very interesting that the color profile make a noticeable difference. I may test it more on different settings.

                                    Jerry I am examining more GPU's on devices that cause me issues, and comparing their color rendering to GPU's that do not, and there IS a noticeable difference. And an ICC profile would change the color rendering. This points to color rendering being a big culprit

                                      Kray You forgot to mention light flicker from LED light bulbs，from cheap CFL light bulbs etc.
                                      It is not good enough to fix your display if the light source in your room flickers at levels that are harmful for you.
                                      I had to do a lot of research to find light sources that I don't get headaches and eye pain from.

                                          KM For the last few years I have been using a combination of different light sources: CFLs(philips，osram) in places where I don't spend much time like in the hallway/bathroom，I use LED lamps(warm 3000K) that have a DC transformer with the light flooding the walls(I don't like direct LED light) at the same time with desk lamps and floor lamps with halogen light bulbs in rooms where I spend more time.
                                          I also have a Panasonic plasma tv，I use my laptop at maximum brightness with a software color filter to dim the brightness and use f.lux with 4500K for the day setting. At work I bought a Dell u2414h(DC driven backlight) at 44% brightness in the “Paper”(low blue light mode) monitor profile and f.lux installed with 4500K for the day setting and have no red eye/head aches/sand in the eye sensation after 8 hours. The light at work is from fluorescents with electronic balasts(nothing show when I filmed in slow motion).
                                          I own an LG Flex2(flicker-free) on which I do a lot of reading daily.

                                          I've been a computer programmer for 7 years now and got to the ophthalmologist recently and I still have 20/20 vision. As you can imagine I had a lot of problems at the beginning(there was very little on the net at that time，felt like I was the only person with PWM health problems) so I did a lot of research and that is my current setup.

                                          I currently found 2700k or lower LED spotlights and light fixtures(with DC transformers)，OSRAM DULUX INTELLIGENT LONGLIFE CFLs which are suppose to be flicker-free and a very warm CCFL light bulb(these are rare). I will try to combine all the the best from all the lighting technologies and I will let you know how it goes.

                                          If you want specifics on which LED lamps I use etc. ask and I will give details in another post as this post is already too big.

                                              PuffyCloud LOL. I've been a migraine sufferer for over 16 years now with CFL and LED lighting as my primary trigger. I wouldn't be surprised if I have more experiences investigating and getting treated for eco lighting triggered eye strain than everyone else on this forum combined. I didn't bring it up cause this forum seems to be focused on screen, not lighting.

                                              My entire home is lit with incandescent light bulbs. I have enough stocked away to last me the rest of my life.

                                                  I certainly care and I'm sure many other people do as well.
