I had an employer get me a nice laptop years ago as their default was a 
pos, an asus ultrabook that this sounds a lot like.  It was entirely 
wrought with issues I never could resolve trying to make ubuntu work on 
it from suspend issues, display glitches, gpu driver issues, efi 
weirdness (no legacy boot options), and in general, pretty disgraceful.  
I think at the time I was using 12.04, ended up going into 13.10 to see 
if a newer kernel helped anything, and finally gave up, letting a ~$3000 
waste in my desk as useless using my crappy business hp laptop until I 
moved on.

Sadly, asus seems to be the new toshiba with laptops and linux for 
bugginess and giving a rat's ass to make compatible hardware for 
anything other than windoze.  I remember even nouveau freaking out to 
even install the os from an ubuntu desktop cd to install it, took like 6 
hours with the cpu pegged at 100%...  DI-based installs for some reason 
I don't remember didn't work either.

Never again Asus laptops here...

That said - Cables are a huge issue with 4k tv's - I'd suggest getting 
some of the cables like monoprice sells with the active Cabernet chips 
in them, as supposedly they work better when dealing with hdmi2.0 + hdcp 
garbage, and keeping stable at real 4:4:4 mode, especially with distance 
more than 2m or so.

Other than that, best to use xrandr to probe the monitors, and watch 
your xorg log files to see what it's doing when they connect.  If 
nothing, it could be the bumblebee bit (worst buggy things I've seen in 
forever this dual-gpu nonsense) not switching cards appropriately, but 
if xorg sees the monitor, and xrandr can confirm it sees the display, it 
*should* work.
