hansennn Replied to other thread, but I got the Skinomi for both my Moto G and the Blu R1 HD. Both were cut to fit and for sale on Amazon. There was no setting on the phone I had to change, I just apply the screen protector and never got eye strain from the device again

    2 months later

    After three months of testing the dell xps8910 desktop with nvidia geforce gt 730 graphics card and BenQ GW2760HS monitor. Now I think I can safely report that this setting works for me. It is still not perfect, but MUCH MUCH better than my yoga pro laptop with Dell ST2310 lcd monitor. It is not easy to reach this conclusion because many factors had to be controlled and ruled out. I think the discrete nvidia graphics card is a game changer for me. The monitor is directly connected to the graphics card, not the motherboard. The integrated graphics card is disabled. I have a similar set up at home with nvidia GeForce GTX 750 Ti card and BenQ EW2440L monitor. It works fine too. OS is windows 8.1 at work and windows 7 at home. Tried linux on the computer at home for a few days, but did not feel any noticeable improvement over windows. I may go back to test linux for a longer period of time. I also tried my old Dell ST2310 lcd monitor at 100% brightness, not as good as the BenQ monitors, so I guess I am sensitive to dithering since the dell monitor use FRC.

      Jerry Awesome news

      As a point if data gathering, can you check what (if any ICC profile you have installed?

          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.

            image icchome-png

              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.
