1NGIBITOR I haven't done extensive testing yet, but as far as I know the 1070 is a problem even before Windows boots (In the BIOS)

    i think nvidia intentionally forces crappy dithering on their consumer cards to get pro video production people to buy quadro. they also make it hard to switch between types of cards

      reaganry That might make sense, but someone on the Nvidia developer forum reported temporal dithering on a Quadro card of the same generation as the 1070.

          Seagull yeah, the dithering is a downscaling thing required for accurate color reproduction on 6 and 8-bit monitors; without it, you get the banding. the pro tv people all use fancy 10-bit monitors & are willing to pay extra & forgo gaming speed to have the computer to spit out undithered 10-bit. I think they wont use HDMI either.

            JTL i bet the quadro dithering is less crappy and can be turned off 🙂

                reaganry From what I remember, [they] (the person trying to do PCoIP) had problems no matter what drivers were being used, etc.

                  So I bought a used GTX 1070. Tried it for about 2 weeks, unfortunately its a no go. I get eye strain. My eyes burns, with muscle twitches and all. This sucks. I tried connecting to my monitor using HDMI cable - eye strain. Next i tried using DVI port with a DVI to VGA converter and use VGA cable to my monitor - eye strain also. I tried using HDMI port with a HDMI to VGA converter and using VGA cable to my monitor - eye strain again. So my theory (in another thread) on how analog signal can flush out the thing that is causing us eye strain doesnt work with PC. https://ledstrain.org/d/483-android-tv-box-eye-strain-and-solution-for-pc-also/17

                  I tried the oldest driver I can find (from the CD), no go, and I tried the latest driver, also eye strain. I gave up after about 2 weeks.

                  I read the thread about GTX 970 and how AgentX20 can use his 970 without a problem. So I bought a used GTX 970, exactly his model, which is Gigabyte G1 Gaming model. I have been using this GTX 970 for a about a week now, and thankfully I can use it without eye strain. Phew. Thanks AgentX20. At least my home PC gets a bit of graphics upgrade from its GTX 760.

                    Kray How did you know you were buying the right v1.0 version (e.g. with no Samsung memory as @AgentX20 said), could you see this on pictures or were you just lucky?

                        Yikes, there are different versions of the Gigabyte G1 GTX 970 graphics card? I must have missed that. What I understood from the thread is that different GTX 970 cards (from different makers) can cause eye strain. That's why I bought the exact model used by AgentX20, at least I know this model can be used by someone who suffers from eye strain like me. I didn't know there were 2 versions of it...and I dont know which version I got, its already installed. I guess luck is on my side this time.

                            You can't easily tell which version of the Gigabyte Gaming Edition 970 1.0 hardware you have. You need to install it and use something like GPUID to identify what memory is on the card. Of course this all assumes my theory about which ones work (Hynix) and which ones don't (Samsung) hold true, and it's not some weird BIOS variation.

                            I noticed the cooling fins are slightly different between the two cards I have at present (one good - Hynix, and one bad - Samsung) but it's very subtle. Perhaps it's evidence of different sub-manufacturers?

                            Glad you got a good one Kray. Maybe you could run CPUID up and let us know what memory you have on your card?

                                JTL Correction: It's GPU-Z

                                Yep - that's the one! Thanks 😀

                                  I ran GPU-Z, and I got the Hynix one. Wow, it was a 50-50 chance and somehow I got the good one. What a relief.

                                    Kray Would it be worth comparing the VBIOS version between both of these good 970's? The bad card may have a different version.

                                        diop I remember @degen said his 970 was "bad" and the VBIOS was later then a possibly "good" card.

                                            2 months later

                                            BTW the problem seems to be not limited to new video cards. I tried to use GTX970 with my new z390 chipset motherboard with no luck (also tried internal motherboard Intel VGA). There was still eyestrain . The same thing goes for my old X79 chipset + RTX2080. Only gtx970 + X79 worked. Don't know what's going on. Hope my eyes will recover from such a heavy blow over time. No more experiments. I quit PC gaming from now on. But still I'm going to try the next generation playstation when it's released.

                                              1NGIBITOR were you using Windows 7 or Windows 10 v1511? If not, you will have eyestrain no matter what.

                                                  Hey everyone, I also experience eye strain but with the GTX 970 (ASUS STRIX). Yet if I change over to my onboard graphics (Intel HD Graphics 4600), I experience ZERO eye strain! I have logged a support ticket with NVIDIA, but I don't have high hopes in getting a solution. I wonder if it was a driver at some point that has caused this issue as I'm sure I didn't have this problem when I first got the card. Am going to install the oldest driver I can find for the GTX 970 and see if any change occurs!!

                                                  Gurm I don't have problems with Win 10. I use it at work on the other desktop. And I have problems with the new VGA even in BIOS, let alone win 10 and 7.
