Firstly, please check if you can find a icon () on the bottom right of the screen, if not, the tablet does not correctly connect to your computer or the tablet drive did not correctly be installed in your computer. If you can find the icon () on the bottom right of the screen, please click it and try to test the pressure sensitivity on the pressure testing area to make sure if the pressure output data of digital cordless pen is correct. After testing, if you still can not find out the pressure sensitivity in the Photoshop CS software, you can contact or ask for help from Adobe Online.
