Guild Wars 2

I have an issue when I play the game on my laptop which has a 4x display with a native resolution of 3840×2160. My desktop resolution is set to its maximum.
If I play the game on full screen mode (mainly 1920×1080), my game gets stuck on loading screens and stays that way unless I ctrl+alt+delete out of the game and alt tab back, in which case some of the graphics (such as water surfaces) are distorted.
When I play GW2 on windowed full screen, I no longer have the above issue, but every interface item looks so small and quite unreadable (including the minimap and chat) even when I set the interface size to the largest available option.

My graphics card is GeForce GTX 960M with the latest driver. Windows 10 x64.
The way I see it, either having a way to fixing the graphics issue, or a way to increase the interface size past the game’s available options could fix my problem.

Any help would be appreciated.
