HDMI 1.4 doesn't support 4K/UHD, but HDMI 2.0 does. Since you have a 4K TV, your TV should have a HDMI 2.0 port (typically 4K TVs have one of these, but they may all be HDMI 2.0). Does your PC happen to have DisplayPort, Mini DisplayPort, or USB Type-C connectors? If so, you could get an adapter to go from that to HDMI 2.0. Having said that, it may or ...

It's quite simple actually - find the "Displays" utiltity in the dash,and drag the "Scale for menus and titlebars" slider to the right, which will make everything bigger: Another possibility would be to lower the resolution, which would also make things bigger on-screen. A third possibility may be to change the DPI, but that's somewhat complicated. (...

This might be because both of your monitors work in 60+ hrz range. Try using xrandr to manually set them both to, say, 50, or better 40, and see if it helps. Most of the laptop graphic cards do not support 120+ hrz frequency which you would need for two monitors both having 60+.

Putting scripts in /etc/pm/sleep.d/ will no longer work as a result of the move to systemd from 15.04. If you want to experiment with such scripts, you can put them in /lib/systemd/system-sleep/ instead, though you'll also need to make some minor changes to them as the parameters that are passed are different. From man systemd-sleep: The first argument ...
