Safe hardware PC builds list

Until I see a disassembly of it, along with a specsheet of it (since it's basically emulating a oscilloscope + light probe setup, characteristics such as bandwidth of probe and device itself, shape of frequency response etc.), I don't consider it a valid option for comparisons.

Ideally, one would disassemble panels and probe the backlight itself for brightness fluctuations, but this is not possible for most.

5. Software also matters, I'm using Win10 1809 17763.1098 with updates blocked

You wrote earlier:
"Here is my safe workstation: 9600kf/Gigabyte z390d(F2)/Asus 2070s(466.63)/win10 LTSC 1809 build 17763.1098"
if Windows version is so important, can you specify some subtleties:
1) Windows 1809_LTSC or 1809_"regular" ?
2) build 17763.1098 is obtained immediately after a "clean" installation?
(if so, could you please write the full name of the .iso image and its MD5/SHA checksum)

I can't find the original Microsoft LTSC_1809_build_17763.1098 image
I'm installing the initial LTSC_1809(build_17763.316) + kb4538461(Cumulative Update March 2020) = LTSC_1809_build_17763.1098
I don't know that these are equivalent actions...

what CPUID does your 9600kf have? 906EC or 906ED? (you can look in AIDA64 https://download.aida64.com/aida64engineer735.zip)

what is the MICROCODE version AFTER loading Windows? (you can also look in AIDA64)

6. Using CRU, you can remove the monitor's color data to allow Windows to use the "default" color space without transforming.

Can you elaborate a bit on "remove monitor color data"? Is this related to edit EDID info ?

When I sit in my z390+rtx2070s, pain between brows begins after 2 hours. I switched GPU to gtx1060, cleared CMOS removing battery, and pain stopped

Do I understand correctly that z390+2070s is easier on the eyes than z690+2070s(same)? But z390+1060 is more easier than z390+2070s? Have the VGA drivers version been changed?
What is the full name of the 1060 model(+BIOS ver)?

How can you claim the Opple and Radex are "good enough" when there isn't a single datasheet or spec sheet of the probes used and of the scope / device itself? There aren't any teardowns of both devices either.
You can use a screwdriver to hammer down a nail as well. Something may work, but is not optimal for the task.
"Any cheap handheld scope" is not a optimal setup for properly evaluating backlight brightness stability.
Dithering testing requires a oscilloscope + probe as well, microscope doesn't tell us anything.

I switched GPU to gtx1060, cleared CMOS removing battery, and pain stopped

after switching. besides the feeling of pain, do you see any visual difference in the image, banding for example?

My 9600kf have 906ECh cpuid and AEh microcode,

even earlier you wrote:
"the build number is very important: 1809 LTSC 17763.1098, the next 2 processor updates (kb4589208 and kb5035849) will bring back your eye strain"
https://ledstrain.org/d/2712-windows-with-colorcontrol-still-makes-me-eye-strain/13

bios F2 contains MicroCode 0xAE for 906EC but Windows can update MicroCode
(in particular, kb4589208 updates MicroCode to 0xCA for 906EC)

my guess: if one installation of kb4589208 ONLY adds a eye strain, perhaps the MicroCode version is ONE of the factors ??

After that I found my benq with DVI connection is very calm and after CRU checking, found all blocks are empty, so using DP cable I reproduse DVI condition to get calm monitor behavior

If I understood you correctly, the same monitor connected via DP causes less eye strain with the EDID modification than the same monitor/DP but without the EDID modification?

100% safe grapfic card with giga z390d (F2 bios of 2019.10.15): white color asus gtx1060 dual, GC BIOS is 86.06.0E.00.41, connection via HDMI to DVI cable

HDMI on VGA side ?
in nvidia control panel such connection is displayed as DVI or HDMI?
I'm trying to understand: does eye strain depend on the type of monitor interface (in a potentially safe combination z390/1060/17763.1098)

I found gtx1060 and 1660s (which is safe according to this forum)

unfortunately not all 1660s are safe (

https://ledstrain.org/d/1524-eye-strain-with-new-gpu/79
"Before that i use gtx 1660s inno3d twinx2 gddr6 SAMSUNG and this one is the best. No eyestrain at all.
Then i use gtx 1660s inno3d twinx2 gddr6 micron and hyenix and make me feel eyestrain."

there was also a discussion on this forum about the safe variety of 970, the general conclusion that I remember is that only one specific variety is safe (Gigabyte G1 Gaming 970 version 1.0) not all Gigabyte 970 (

I also tested whole week miniPC (13700h + Iris XE 96EU) with same benq HDMI-DVI-D cable, seems okay, similar to z390d+gtx1060

i5 12600k + UHD 770 ) - all is OK

is there a difference in eye strain between these configurations?

You know, I exported all registry settings to find difference after changing 2070s to 1060 and found nothing

and have you experimented with DitherRegistryKey in registry ?
