              Hello Fajarakv,

              Thank you for your response.

              I was checking the information and I see that you have a system with hybrid graphics. It is recommended to get in contact with the manufacturer of the computer when having graphic-related issues since there is an order in which the drivers must be installed. 

              Now, I want to help you and see if there is something we can do for the problem you are currently experiencing. We are going to try to do a clean installation of the graphics driver. Please follow the steps below:

              1 - Download the .zip driver from https://downloadcenter.intel.com/download/27894/Intel-Graphics-Driver-for-Windows-10
              2 - Disconnect the computer from the internet. 
              3 - Go to device manager and check under display adapters.
              4 - Right-click on the Intel ® Integrated Graphics, select the option uninstall and keep going until you only have Microsoft's basic display adapter.
              5 - Unzip the file you downloaded previously.
              6 - Right-click on the Microsoft's basic display adapter and select "Update driver".
              7 - Select the option "Browse my computer for driver software.
              8 - Select the option "Let me pick from a list of device drivers on my computer". 
              9 - Select the option "Have disk".
              10 - Select the option "Browse".
              11 - Access the designated location or folder where you unzipped the driver downloaded and access a folder called "Graphics". 
              12 - Select the setup information file (Typically named either "idglh64" or "igdlh").
              13 - Click on open and then click OK, finally click Next and the drivers will begin to install. 
              14 - Reboot your computer when the installation is completed.

              After following the steps above, please check and see if you can connect to the TV or if the problem persists. If it does, let me know please.

              I hope this helps.
