Were you playing game and screen got rotated by 270 degree or flipped ? Here is the solution to disable hot keys for rotating screens.
The hot keys are provided by your graphics card driver or by inbuilt graphics memory provider (may be Intel on board graphics).
To disable shortcut keys first you reset your monitor display so you can work easily without rotating your neck. Press CTRL+ALT+Up Arrow. Normal uses this key combo by default.
Go to Display Properties (Control Panel > Display > Settings Tab) This can be also achieved by right clicking on desktop and selecting properties.
In settings tab press “Advanced”. Go to your graphics provider tab (Usually Intel Extreme Graphics) and press “Graphics Properties” button.
There you will see another tab named “Hot Keys”. Uncheck “Enable Hot Keys” and accept all changes by pressing OK buttons one by one.
Normal users hardly need the hot keys better use the PC like it’s yours , not like it’s of manufactures’.
