Iv had this monitor for a couple months now and no issues, occasionally using the menu to change a couple setting here and there. Now when ever i try and push up to access the menu it wont allow me to select that option. The other 3 options work just fine, and when i access those i can push up, the direction of the menu option, and it seems to also be working just fine. It also seems like pushing right might nor be registering but with the few options i have i cant really be sure about that. If i push right with no menus up nothing happens. My monitor is updated to the latest firmware as well, can anyone help me figure out a solution?
