G3223Q, cannot see activation of blue light filter mode

The G3223Q panel is built-in low blue light and always on. This means the G3223Q did not need the additional S2721DGFA Menu- Game- Preset Modes- ComfortView option.

See page 8 in the online G3223Q User's Guide =

Thank you. But i have another question. i have Dell 32 Gaming Monitor - G3223Q
User’s Guide which says : in page number '8' : Optimize eye comfort with a flicker-free screen and ComfortView feature which
minimizes blue light emission.

i thought that it was an additional feature.

other question is :

it says in page number 8 :

The Monitor uses Low Blue Light panel and is compliant with TÜV Rheinland
(Hardware Solution) at factory reset or default setting. This always on, built-in
low blue light solution reduces hazardous blue light emissions, without sacrificing
true-to-life colors.

it looks if i change any value like (brightness , contrast, or screen mode etc) I thought I would have to give up that built in feature. (Because of ) 'at factory reset or default setting sentence'

could you please reply me? Thanks.

@Challenger720, instead of using an RGB gain to get a warmer white they moved blue peak to 460nm so a D65 white configuration will be close to other WLED PFS displays, jus a blue spike spectral power distribution moved 10nm to the right

All this "low blue light" stuff from every manufacturer is a sc4m.
-For "traditional displays" is just a yellow whitepoint, hence all displays have it as long as they have RGB gain controls.
-Eye blue sensivity maxes at ~450nm and moving peak to 460nm for these TUV certified displays (your dell) just lowers a little the emited power at 450nm which is still high(~80% of main peak).... but all these does not matter. Spectral data is in DisplayCAL colorimeter correction database:
https://colorimetercorrections.displaycal.net/?get&type=ccss&manufacturer_id=DEL&display=DELL%20G3223Q&instrument=i1%20DisplayPro%2C%20ColorMunki%20Display%2C%20Spyder4&html=1
This TUV licensing/cetofication scheme is based on BS, a sc4m, our eyes are evolved to work with blue light and maxes response of z-bar CIE observer at 450nm. False claims based on in vitro cells damage with ultra high pulses. There is nothing between 425-450 that will harm your eyes.

Hi, thank you so much for your reply.

What about blue light less glasses (not cheap ones not gaming glasses ) (i meant eye doctor recommended ones) (sorry for my bad english) (they make a little yellowish when we look into that glasses)

can we say that even we use no glasses no filter we will get NO HARM from those things?
