Indeed I might try to buy an already assembled PC from ZNXT and in case make the return.

But first I want to try to change monitors to an LG 27GR95QE OLED 2K 240HZ monitor! My dream and I've never had any problems with OLED devices except for the iphone 14 pro, so I'm pretty optimistic!

Lauda89 Why would you be getting the same motherboard as I have when I'm telling you it's already bad! It's a GIGABYTE B660 GAMING X, the large one with 3x M.2 slots.

I am also not sure we understood each other with the graphics card… is the 1660 super bad too when you install it in your old motherboard (crosshair vi hero with ryzen 1700)?

      machala Sorry, I understood that with the gigabyte you were able to solve the situation.

      I only tried the 1660 in the new PC with the Ryzen 7900! I don't want to try it on the old PC.. it's the only problem-free PC I have and I don't want to risk it.

          Lauda89 You know what? I totally understand what you mean… I am in the same situation with my old intel haswell-based system with a 660…

          and again, no the Gigabyte motherboard is bad, very similar symptoms to what you describe with your AMD system. That's why I believe there's no guarantees you would be good with a 13xxx intel system.

            Lauda89 Can you please tell me what type exactly is your new motherboard? Name and manufacturer… Many thanks.

                JTL have you tried radeon 5700? seeing them for $200

                    reaganry No, but while I'm still performing more research I have reason to believe that conventional Radeon cards may not be equivalent to the workstation variants.

                        I try steam deck 64gb and found that steam deck very please for my eyes. Zero eye strain. Steam deck is no dithering.

                        Lauda89 Just an update..

                        I installed W11 with the latest updates and am using the 1660 SUPER with the DVI --> HDMI output of the monitor.

                        With the DVI output, the situation has improved, and it gets even better by setting limited RGB. Let's say that with DVI + limited RGB I can use the PC. It's not perfect because I can't stay relaxed, but for playing with it 2/3h is ok.

                        Unfortunately with this setting, the monitor colors suck and I am limited to 120hz (my monitor is 240hz).

                            Received a Gigabyte 6650XT Eagle. Immediate eyestrain with both Windows 10 22H2 and Linux. Connected via Displayport. Super Resolution enabled. Patching my non-dominant right eyes results in no eyestrain. Will get an eye exam and possibly prism glasses this week. If that fails do make it better I will try the new Intel Arc GPU then W5700 then W5500.

                            I don't believe font rendering to be an issue for me. I suspect dithering.

                              Yes the 6000 series has dithering always on.

                                At least one person also reported eyestrain with an RX5000 card also…I only hold out hope for the 5000 workstation cards.

                                  RX 580 ARMOR 8G. I used Dvi only. I had an LG wtp227pf. I had never eye pain with it. Never noticed dithering, but perhaps it was there. Not sure.
