The A33 chip doesn't have support for resistive touchscreens, and it also doesn't have HDMI support. That is why the official Android image for the board has the video output set to work only with the 5" display with capacitive touchscreen named "LCD-OLinuXino-5TS" (the only display w have with capacitive touchscreen). It is important to notice that you also need to use the on-board LCD connector to establish the connection to the display. By default the plastic header of LCD is not placed so you would also need to place it.
