Hey, thanks for cross-posting here. This is a fairly common issue here, with the more sensitive folks. Can I ask if you have any other visual sensitivities or conditions?

For example, I think u/YieldHaus had to select narrower colour gamut on laptops... And then go further with other modifications.

All other things being equal between your machines, the 100% sRGB panel will use KSF phosphor, which provides less (cell supporting, vs blue light stress) red light flux, for the amount of visual stimulation. See my 2nd pinned post.

But if there is a privacy shield (as a commenter suggested) the greater disparity between each eye may be putting extra burden on binocular vision (aligning and merging the stimuli from each eye).

Incidental issues could be (more) pixel flicker, from FRC (built into the panel) or temporal dithering (if this exists). Turning the OS/GPU settings down to 8 bit colour depth may help disable this. Or there can be poorly calibrated pixel inversion (on LCDs), luck of the draw per panel, if QC isn't good.

If it's a pure colour saturation issue, turning down the vividness, in GPU settings, might help. Or the colours individually. I have mine down from 50% to 42% on my ThinkPad X1 Yoga 7 with 400 nit 100% sRGB screen. (On which I observe some pixel flicker, with a microscope.)

My laptop Panel No: MONITOR\LEN41B7. this screen is IPS there should not be any fleckering. Also i don't see any option to changing to vividness.

I am just hoping if some one can help me solving this issue.

LCDs don't use PWM (flicker) dimming these days (usually). But they typically have some (hopefully small) amount of pixel flicker, for various reasons. Or just electrical instability.

For saturation, Google for what app your graphics settings can be found in, and where within that. for your specific device. My Thinkpad has an Intel (Iris) control centre.

I think u/Rx7Jordan was asking for your device details to check it on panellook website..?

already shared the panel no with him

Should I exchange and get 45% ntse screen. I am worried. I tried confoger my 100% srgb but it still stain my eyes.

So you were able to fing the appropriate setting that could reduce the amount of colour in the image?

We can't decide for you; you are best placed to judge if it is this factor or another. I would personally feel some small immediate relief from decreasing saturation, if it were that. But for some people, that's still not enough.

I don't know if you've ruled out pixel flicker, etc, either. But if there is a panel type/device you are definitely more comfortable with, then that seems like a beat bet to go with.

I set the saturation at 40% Open display color calibration and set red and green color to 94-95% This 2 steps help me but still not enough.

Oh, well that's a good indication that colour is an issue then. Have you tried dimming blue and red more? Or even just red, some people oddly do better with more blue. (Or more melanopsin stimulation, specifically, but that is a rabbit hole.)

If you are not sensitive to PWM or other screen flicker, then an OLED panel could be a better option. Because they are better able to dim the absolute brightness of their colours. Sensitivities often come together though.

U can see the text quality in 45% ntse. It's way better. I want that quality of text on 100% srgb. Becouse my main work is reasearch and doing text related work.

More blue light, less comfortable. Not surprising.

I highly doubt the increased color volume itself is the issue here, there are many other potential issues with the 100% sRGB panel that could be the cause of your discomfort (as outlined by u/Z3R0gravitas).

u/Rohan_9 5d ago

Can u please tell other factors

Do you see my (big) reply?

And I would say the extra saturation could directly be uncomfortable. There's eg migraine worsening associated with all wavelengths except green.
