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&#x27;s any issue is when bandwidth is limited for whatever reason and the site needs to drop down to a lower quality stream.<p>I assume you&#x27;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 &quot;mostly works&quot; driver that comes with the OS, I&#x27;ll notice issues with performance because I&#x27;m missing any hardware acceleration that the Intel&#x2F;nVidia&#x2F;AMD GPU can do.<p>Typically I notice it on work machines that just got reimaged with a generic OS image and don&#x27;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.<p>Again, I assume you already thought of this if you&#x27;re specifically buying a higher resolution display than the average cheap PC comes with.  Still, it&#x27;s the only thing that I&#x27;ve had affect framerate&#x2F;refresh in fullscreen video in the past.
