Lenovo Ideapad 1 15ALC7 and SEUC0422 duel monitors not detected.


  • I have an lenovo laptop and I plugged in the HDMI cords into the docking station and connected the docking station into the laptop and my keyboard and mouse work but not the monitors? 
    I check my drivers and I have the latest version? 

    laptop model number 82R400DTUS



  • Hi @Tony Prout:


    I'm sorry to tell you that after checking.


    The C port of your computer does not support video output, and the product using DP signal master control is not compatible; so the video cannot be displayed. This is due to your computer equipment. It is recommended to change the computer that supports the equipment and try. 


  • Thank you


  • You're welcome😃
