@prrace  I have slightly changed the description as per your suggestion. Please let me know if any changes are required.

**HORIZONTAL - the test instruction frame is positioned such that the right edge aligns with screen's vertical center and the test window is placed to the right of the instruction frame.**

**VERTICAL - the test instruction frame is positioned such that the bottom edge aligns with the screen's horizontal center and the test window is placed below the instruction frame.**

**TOP_LEFT_CORNER - the test instruction frame is positioned such that its top left corner is at the top left corner of the screen and the test window is placed to the right of the instruction frame. (Taskbar placed at the top of the screen in this example)**
