What works for you, what do you use now without problems?

Best working for me (22nd of March):

Desktop

• Windows 7
• Intel Skylake CPU (6th gen)
• Integrated Intel graphics with "Standard VGA" driver (better than Intel driver with Ditherig)
• Dell 2208WFP ( TN panel, no FRC, CCFL backlight, can be made PWM free )
• Opera browser, IE 11 (others give eyestrain, worst is Firefox Quantum)

I am not a gamer, so this setup is working for me. Currently waiting on old ATI FireGL graphicscard to test the 10bit mode that worked for me on a Thinkpad W500.

Laptop

• Thinkpad W500 with ATI FireGL chip in 10bit mode (have 2, one is working, the other one not. Could not figure out yet what the difference is... Seems to be related to VBios setting. Bad one has dithering even on BIOS screen)

Phone

Have not found any working phone yet. iPhone 7 Plus and iPhone 8 Plus seem to be ok for some time.

Update from 26th of March:

Desktop

• Windows 7, Cleartype off
• NVidia Quadro NVS 295 (only one monitor connected, two increase flicker)
• Eizo CG223W ( S-PVA panel, CCFL backlit, has PWM and probably FRC, but way better than previous TN-panel. Do not get "foggy mind" anymore )
• Opera, FF Quantum still "painful"

Best setup yet. May check the NVidia card also with Linux and Windows 10.

Update from 27th of March:

The Windows 7 / NVidia / S-PVA panel setup is awesome. Best I have had in years! Just found the other devices I used to be worse than expected. Guess I got used to the headache already?

Laptop

• no laptop yet that is as good as my current desktop setup
• Lenovo W500 with ATI FireGL dithers as well (only noticed it after two days sitting in front of my "perfect desktop" setup now )

Update from 29th of March

Can say that some NVidia cards are just a joy to work with.
Currently I own 3 but only 2 of them are "good".

Good:

• NVidia Quadro NVS 295 (got mine for 4 EUR on Ebay)
• NVidia Quadro K420 (got mine for 40 EUR on Ebay)

Not good:

• NVidia Quadro FX 3800 (no clue why this did not work for me honestly)
• ATI FirePro W7000
• ATI FirePro W5700

deepflame I've been wondering if quadro was going to be the solution. just ordered one to try - $8 on ebay! [edit] pretty nice so far (displayport only fyi). but.. DX11 games, VS Code, Unreal Engine wont even launch & it seems there's no way to switch back and forth between cards in win10?

reaganry Yeah, the NVS 295 are super cheap. Got mine for 4 EUR off ebay. Ordered a Quadro K420 to get more graphics power and to be able to play some games with my son.
I will certainly update on the K420 .

For me it is also the panel it seems. I have different screens here (accumulated them over the past years to figure out what is going on) and will test again.
For now having this S-PVA panel is the best even though it has PWM and FRC. Will get a Dell 2407wfp on Monday. Said screen should also be S-PVA.
TN seems to make me sleepy (tension in the back of my head), the IPS panel I have gives me a different strain. All are CCFL backlit.

diop Windows 7, current driver (430.86).
K420 actually seems to be better than the NVS 295 using Chrome 74. Really a joy working with it.

Tested the NVS 295 also with Ubuntu 18.04 and appeared to be ok. Will test it with the K420 as well.

AGI No, it is definitely the tech for me. The Nvidia K420 is really good (if you don't have apps open that makes it dither again). I can also play videogames with my son with it which is really cool!

Think I have not written down my complete story here yet but it all started around 6-7 years ago, I think when I bought myself a MBP 13'' unibody with LED backlit screen.

Not sure exactly if it was the device or if it got worse after an upgrade. At least more and more devices like iPad, iPhone, DLP projector, made their way into our home and I spent more and more time with those.

I am a software guy and I was quite lucky around 6 years ago that I got into presales and professional services. So I could spend more time at the customer site and did not have to stare at screens all day long.

When I moved back to Germany I remember buying an Eizo LED backlit flickerfree screen that I connected to my MBP. Looking at it made me feel like looking into the bright sun. Also like needles being pinched into the back of my eye. It was very painful to look at!
This is where my journey looking for a good working environment began and it seems that after all these years I have finally arrived.

With the current setup (Windows 7, Skylake processor (for Windows 7), NVidia Quadro K420 and the S-PVA screen having the "wrong" apps closed) is really good to work with.

So the next step would be to get a good laptop that I could at least use for some time (I am looking at the Thinkpad W530 or W540 with NVidia Quadro GPUs, but have LED backlit screens).
And to get a smartphone that is not painful to look at. I get eye strain looking at my iPhone 6s (sorry, I meant 6 Plus) with iOS12 after just a second or so. Same for other devices that are using dithering.

Hope that helps
Please don't hesitate to ask more questions if there are.

AGI Do you have perfect vision?

No, I have astigmatism with -4 and -5 spherical value.

AGI Have you ever had any thought it might be your eyes to cause digital eyestrain, and got checked?

Yes, I got it checked and it did not get better with new glasses. When I am away from my screen I do not have issues. So it is certainly the computer.

AGI How about LED and fluorescent lamps?

Had to remove all LED bulbs in our flat. That already calmed down my neural system a lot! Have halogen bulbs now. They last way longer than incandescent ones. No problems with fluorescent lamps as I know.

AGI Uh, I bought an open box iPhone 6s a week ago on eBay

Sorry, my bad. I have an iPhone 6 Plus, not 6s. My wife has a 6s. However that got worse after she upgraded from iOS10 to iOS12. So if the phone still runs iOS10 and you can bear it I would refrain from upgrading it...

deepflame So if the phone still runs iOS10 and you can bear it I would refrain from upgrading it...

Thanks on the tip! I will see when it arrives. It is an "open box" item. I hope they do not update the OS before shipping!

deepflame No problems with fluorescent lamps as I know.

Since I changed job, I have developed eyelid and face muscle twitching. After quite some time, I figured out it is mostly caused by the ceiling fluorescent lamps. I do have fluorescent lamps in the apartment I rent, and I have no problem. I tried to look at the emission spectra and wavelength-wise I cannot find a clear difference although the "bad" lamps look of a warmer color. Funnily, I can see by the naked eye the bulb in my kitchen flicker and it does not bother me. I am clueless.

diop Have you tried Windows 8/8,1?

No, but this is a good point. I always disliked the new start screen but just found out that it is possible to bring back the "old" start menu from Windows 7. Good to know to have this option.

diop Are you affected by temporal dithering?

Well, I am not sure what kind of dithering it is (seems there is also spatial dithering) but I am highly affected by pixel flickering. Also DLP projectors give me strain after a while.

diop Nvidia driver settings

Please let me know if you need anything else.
I need to add that I have disabled "ClearType". Not sure if this is off by default. Turning it on makes the screen unusable again.

diop I can see these Quadro K420 cards are very affordable on the used market

Yes, I started with the Quadro NVS 295 for 4 EUR on Ebay and gave this another shot and have to say it is really worth it. Of course I cannot guarantee that yours will be the same because of revision differences. However I have hopes as @JTL had a similar experience with his Quadro K4000 ( https://ledstrain.org/d/337-nvidia-quadro-k4000 ). So it seems to me that the Kepler Quadro cards may generally be good (?).

diop It really is becoming a joke.

Yeah, I know what you mean. My wife is also already fed up with all this "buying new screens and returning them". There are still 7 or so standing around there that I need to sell or dispose. Based on the positive response from some people it is definitely worth it and to never lose hope!
