a) get a bigger monitor.
b) Drag the menu to the top or to the bottom of the screen.
lol like getting a bigger monitor would make any difference????
Anyway, I have the same issue (although only happens with legendary gears with lots of info) and have tried all manor of settings changes with no joy and theres no option to move the menu down as its a fixed menu. Oh & I have a 21 inch widescreen monitor before someone suggests getting a bigger one lol.
TBH, I just move whatever it is I want to look at to the bottom right of my inventory and its ok and as for the stuff like gears in crypt shop I just look at a higher level player to see if they are wearing it to view.
