I also have a 27" 2560x1440 monitor and while the content looks fine, the video gets really choppy if I don't configure my monitor to 1920x1080, as if it's struggling to resize the video. Does this not happen to you?
Sorry for the late reply, but whenever I stream from Netflix, Amazon, or Youtube, I just let it stream at whatever their site determines as the max my connection can handle and it never looks choppy in fullscreen. The only time there's any issue is when bandwidth is limited for whatever reason and the site needs to drop down to a lower quality stream.
I assume you've already covered this but just in case, do you have the most recent drivers and software for your GPU? I know in the past that (on Windows systems at least) using the default "mostly works" driver that comes with the OS, I'll notice issues with performance because I'm missing any hardware acceleration that the Intel/nVidia/AMD GPU can do.
Typically I notice it on work machines that just got reimaged with a generic OS image and don't have the relevant GPU drivers installed yet. Moving windows around, resizing, and other windowing tasks are a bit choppy until I download the appropriate package.
Again, I assume you already thought of this if you're specifically buying a higher resolution display than the average cheap PC comes with. Still, it's the only thing that I've had affect framerate/refresh in fullscreen video in the past.
