lol...thanks for all the obvious tips guys!
Here's where I have issues "trying" 4k...first off, my TV doesn't have a DisplayPort (also according to my mobo specs, the DisplayPort it has only supports a maximum resolution of 2560×1600@60 Hz).
Secondly, the HDMI is only 1.4.
Thirdly, I can't get the PC to output anything higher than 1080p (even tried dropping the framerate to 30hz, although the only option was 30i oddly enough). This is in Windows 10.
Feel free to shine some light on my stupidity, as long as some possible solutions are included as well
EDIT -
I suppose I could actually tell you guys what TV I have... VIZIO M55-C2 55-Inch 4K
