Because increasing the display's frame rate makes zero difference on a S&H display for movie playback unless one of the combinations has jank: If you go from viewing 24 fps content on a 60 fps display it's janky, going to a 120 fps or 144 fps display fixes that jank because frames divide evenly. If you watch 30 fps content, it looks almost exactly the same on a 60 fps and a 120 fps display (but going to 144 fps would introduce jank).

Interesting. So if everything is all the same and it doesn’t matter at all, then why have fps in excess of 60? Just because? > it looks almost exactly the same What is “exactly the same” to you? And does it mean the same to me? And can we measure it?

The different scanout speeds can probably be used to produce slightly differently looking images for 30 fps content on 30/60/120 fps displays. In practice I don't think you'd be able to notice the difference between 60 and 120 fps scanout for 30 fps content.

  The GP comment is specifically refering to monitors used for working with video that's presumably already recorded at <=60FPS. That might be an edge case for general users, but for the people forking big bucks for monitors, it's all they care about.

Every high refresh rate LCD that I've seen advertised also has variable refresh rate support. As long as a multiple of the framerate is within the monitor's range, there shouldn't be jank.

  Browsers don't use VRR even in fullscreen. But yes - that's the correct and by far best solution on S&H displays and would make it a complete non-issue for all common frame rates (24, 25, 30, 50, 60); alas, software.
