More I hear about the Swift the more of a joke it sounds like. I remember reading about some issue a while ago that I'm fairly sure was a different issue to this high hz flickering. Then Anandtech say it flickers in lower hz/fps modes under g-sync. After this thread I searched flickering/144hz and it seems loads of Nvidia and AMD users are getting it. Most got screens replaced and problem went away with the same cable and gpus as before so it's a screen fault. They seem to have really poor quality control, multiple problems all while charging a massive premium.
Find the BenQ price pretty ridiculous though it seems to have a few more features to me, the easy to use/see buttons is something most screens should have had for ages. When I game in the dark room and need to change something on basically every monitor I've ever had it's a nightmare but my Samsungs touch sensitive non buttons are the worst yet. That they can charge what is easily twice what these screens are worth, making them ultra premium versions of the screens, yet have so many problems is ridiculous.
If only the monitor manufacturers could come up with a standard of their own that would run fine with all modern AMD and NVidia cards that would make Free Sync and G Sync obsolete. It makes better business sense to build a monitor that works with all cards than separate versions for AMD and NVidia.
I am sure there are technical reasons that make the above hard but not impossible.
Having both Free Sync and G Sync monitors is a joke.
