I recently recieved a 4K Laptop as a gift (Lenovo Y50 4K Ultra HD), and decided to try SK on it. When playing in full screen on (3840 x 2160), everything except for the actual game is incredibly small, making it nearly impossible to read some game texts, or to see the mouse icon while playing. I've tried lowering the computer's resolution but that didn't solve anything. Please help T.T
You can always change the resolution of SK itself (under "Video" in the options window). I have a 1366 x 768 but SK runs fine in full screen with other resolutions settings. The only problem is some things don't appear on the screen :P
