    I plan to infrequently mirror my laptop display to my Samsung F9000 4K 55'' TV. Would the base 450 be able to handle this without stuttering?

    Or if anyone has experience with both the 450 and 460, is the 460 much hotter/trigger fans more than the 450? I am loving the 450 right now because it runs absolutely silent, cool, etc. I haven't had my fans trigger once. But I have yet to try to power my 4k tv yet due to lack of cables/airplay.

    4k is 4k. Whether it's 24" or 55" or 2000", it'll run exactly the same.

    And my 460 is silent at light tasks, virtually silent during light gaming [Blizard Titles] and only really ramps up during handbrake [and it ramps up early and gets moderately loud, which keeps temps down]

    Of course you could also just invest in an Apple TV and airplay it from you Mac....

    I dock my 2016 MBP with a 455 to my Samsung U28E590 almost all the time I'm home and it runs absolutely fine. In Boot Camp, I sometimes run Overwatch and the game does spin up the fan but it works fine on my 4K monitor (with resolution set at 1440p in the game itself)

    One thing you need to make sure is to find a USB-C-HDMI 2.0 or USB-C-DisplayPort if your TV has it. If you use the Apple Media Adapter at 4k, it runs at 30hz which is dreadful to use. Also make sure your TV has HDMI2.0 if you decide to go that route.
