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.
