K-Moss From the day i sold my GW2406Z i didn't bought any LED monitor, i was too scared. I am using old 19" DELL E198wfp, i had plans to buy DELL Ultrasharp monitor (U2419H) since i am using old DELL now without problems for 2 years.

    NightWolf149 i used to think it was all about PWM and flicker but for me its not. Its the screens native contrast ratio. Ensure the screen has a ratio of less than 1000:1 ( my sweet spot seems to be 850:1). Most Dell screens are about 600:1 which is great. the BenQ GW2255 has a ratio of 3000:1 and Dynamic ratio of 20million :1 which is disgusting eye poppingly dangerous. Hope this helps as its taken me about 26 years to figure this out and cost me a lot of money buying and then having to sell screens, TVs and mobile phones.

        dell U2419 has a contrast ratio of 1150:1 so you might be ok but i personally wouldn't chance it. If you do get it let us know if its ok 😃

        But wait,....GW2406Z has only 1000:1 and that was also bad for me and my current DELL e198wfp has also 1000:1 and that one is ok. Am i missing something?

        it could be a Hz issue. I can't look at TVs with a 120Hz panel but 60Hz is fine. The GW2406z is 75Hz panel and the Dell is 60Hz. Also the Dell has anti glare coating which may help. Reflections can be really aggravating for me. Its a possibility. Also turn sharpness down if that is an option on your monitor.

        Actually BenQ GW2406Z was 60Hz and my current Dell is 75Hz....but interesting thing is that all off the people are complaining at discomfort but my main problem wasn't that, my biggest problem is that my vision got worse permanently after using LED monitors....i am bothered by discomfort too but CCFL monitors didn't ruined my vision while BenQ LED did. I still need to try other ones but for now i am using 60HZ 4K Samsung TV with VA panel and it's ok for now, i don't feel imidiate discomfort like i did with BenQ monitors and my vision is still stable.It could be something whit backlighting,my TV is Edge lit while BenQ monitors and LG TV which i also have and which i also can not watch for long is direct lit.

        DiscoDave So your experience contradicts those who find VA panels more comfortable than IPS. VA always has native contrast of at least 3000:1. You've never found a VA panel that works for you?

          I have Acer nitro laptop with IPS panel and it has 600:1 ratio and I can stare at it all day. I did have a VA panel in my Samsung eh5300 TV and loved it but sadly broke 🙁

          NightWolf149 I will add my experience... Lately I wanted to play assetto corsa on my 49 SONY 4k TV and after 30-50min I was getting INTENSE pain between eyes and later on headaches which lasted for 1-3 days just after that shor gaming time... I really wanted to play this so I tried couple of times witch changing contrast, balance white/blacks and other settings and different game FOV, settings etc. which always ended with symptoms...
          One time tho it ended with vision change in left eye I was scared like you then thought I will have to go to a hospital. I quit the screen right now and went outside... still vision was same. Fortunately for me after like 40mins outside it went to normal but thats a warning: IT'S DANGEROUS , DONT PUSH... 🙁
          Really hoping it will get back for you stay heathly guys!

            @degen , unfortunately, I should say bad. In the past 6 years I have tried 4 monitors on my desktop and my personal rating from best to worst is: Dell P2214H > Benq BL2420PT > Benq GW2255 > Dell U2415. I have always come back to Dell P2214H after trying other 3 monitors. I do not remember being able to bear them for more than a couple of months.

            Since the rest of the environment also has an impact, giving it here:
            o Arch/Manjaro KDE Plasma
            o DisplayPort if the monitor supports, else VGA
