GTX 1070
I'm aware that temporal dithering is off by default on Windows, which is why I've been rather puzzled about my perceived low level eye-strain. It's not a sure-thing 'argh my eyes/head' like what I experienced with an Acer XB271HU recently despite all the flicker-free, low blue light mode, high refresh features.
it is possible it is a combination of tiredness and certain games/sims, so I'm still testing things out with the old and new card. Or it could be something to do with having a DP->DVI adaptor. Or maybe the Pascal architecture/drivers do things a little different?
Either way I don't know of any Windows tools that will tell me whether dithering is active.
This new GTX 1070 card is DEFINITELY causing headaches, whereas my 970 was OK.
Same drivers, same screens. Argh,

On the "Nvidia has dithering disabled" I had a little popup on the "Auto"

This is the linux one, but I imagine it follows similar rules for windows. Sort of a "backup plan" for the card.
AgentX20 I don't know of windows software for nvidia, but it must be available, any software come with the card?
Based on this thread, I see 1 bad for GTX 1070. JTL, is it presenting any issues to you?
I swapped back to my original video card, old drivers and original screen and cables and was still experiencing some of the headaches, although not quite as bad.
I've just been to get my eyes checked - and well, it looks like I need glasses from here on out.
That means I'll have to reserve judgement on the issues I've reported (many/most LED screens, PWM, CCFL vs LED backlights, stresses over certain video cards etc) until I get those dialled in. I do still expect that LED screens are going to be problematic but I'll be intrigued to see what if any issues follow once I'm used to the glasses.
I'll be sure to report back here.
As a long overdue update:
I'm definitely still having problems with my Gigabyte Gaming G1 1070 card, irrespective of the driver version. It's causing low level headaches and visual disturbances. Nothing I've tried has resolved it satisfactorily so far. (I'm wearing glasses now, brightness on the monitor is above the PWM threshold etc). For reference I'm very happily using a near identical screen with a Gigabyte 970 card in the PC next to the 1070 PC without any issues.
Unfortunately I've been unable to find a single instance of anyone else suffering from these hassles anywhere.

Does anyone else have any experience with the new Nvidia 10 series video cards?
In my situation I have a screen I know works absolutely fine for me (CCFL, Dell 24", brightness well above PWM levels) and has done so for many many years, that worked (works!) great when attached to an Nvidia 970 card via DVI.
Now having attached said screen to a 1070 card via DVI connection, I get bad eye strain on the desktop and in 3D games. In fact I only have to have it in my peripheral vision (kids playing) and I start developing the headache sensations.
As I've remarked above I've been unable to find anyone else who has reported such problems. I've triple checked the connections, brightness settings and have the latest drivers.
I fear all 10 series cards are doing SOMETHING with the image that's incompatible with me - which is seriously worrying as someone who has had Nvidia cards for years, without any problems on these same screens. Maybe it's a one-off problem or manufacturer specific somehow, but how on earth do I find out? It's not like I can borrow a bunch of these cards.
Isn't your issue mostly with PWM though JTL?

Plasma (Panasonic ST60) + GTX 970 was my ticket out of the hell I was living. When I got it right I found I could use a PC for hours again. So I started engaging with the world again, and I've hardly stopped to look back, except now. I'm feeling more than a little vulnerable being reliant upon a technology which is no longer in production (plasma, of course) and the possibility (however small) that current or future Nvidia products won't deliver the same kind of results for me. LIterally I want to stockpile old plasma's and 970s.
degen I have tried Plasma TV's before (some circa 2007-2010 Panasonics) but the flicker seems to bother me. I know @jasonpicard has some Samsung Plasma TV's so I wonder if those flicker too.
JTL, it's entirely likely that all Plasmas bother you. All plasmas are a little flickery. It turns out that this type of flickering isn't really something that bothers me (it's similar to an old tube tv, after all) nor is the field-dithering (dancing rows of pixels) something that bothers me. BUT I would imagine that many others are bothered by it, in the same way that I'm bothered by FRC/Temporal.
Good luck!
Yes, I believe plasmas use temporal dithering to display different colors. I saw them flicker especially when the screen was white. Looked like 50/60 Hz. In any case, pretty low frequency. There's a strong contrast between the different frames (maybe pure black).
KM - Plasmas absolutely use temporal dithering but it's a radically different kind which has never bothered me. Modern LCD's use per-pixel temporal dithering, in which each individual pixel is strobed between for example red and blue to make purple (a vast oversimplification). On the plasma, they have entire fields with moving rows of pixels. You'll get two adjacent pixels that will change color inside a subfield. Get close to one displaying different grayscales and you can see the rows of marching pixels almost like a very tiny boardwalk marquee. It happens - in spite of the plasma refresh rate being around 800hz - at about 50-60hz. It was designed that way to maintain compatibility with tube tv's and was never changed. I suspect it's yet another "prevent burn in on the plasma chambers" feature.
I find it acceptable. Perhaps not as acceptable as a good soft CCFL backlight, but acceptable nonetheless. I know others absolutely don't.
I <3 plasma
I make sure to turn off "Pixel Orbiting" and that reduces the flicker somewhat. It's not perfect, but it's the closest I've come to looking at paper.
Makes me wonder how I would react to CRT. My problems started after CRT's were on the way out, and I never thought to check.
BTW I hooked just hooked my 2nd Gen Apple TV to my Panasonic plasma. Eye pain within a couple of minutes. Back to the PC.
