Hi, My Samsung 6300 smart tv used to be able to wirelessly extend my laptop, all until 2 months ago after most recent win 10 update. My computer now only detects it as other devices, and will not detect my tv as an extra screen to mirror or extend the laptop wirelessly. I am only getting my neighbours TV as i'm living in an apartment building If you dont have remote control for your smart panasonic or smart toshiva tv this video might give you some idea how to turn on and off the tv, adjust volume Display adapter drivers. I would suggest you to try the following methods: Method 1: Disconnect all the unnecessary external devices connected to the computer (except the mouse, keyboard) and check if the issue persists. If method 1 does not help proceed to method 2. Method 2: After booting to the safe mode place the computer in clean boot Turn the laptop and TV on select the PC input by pressing the " Input " button of the TV remote control repeatedly. Enter the display setting on the laptop if necessary to project the image from the computer to the TV. Windows 7 and earlier - Open the Start menu and type " Display " in the search and click on " Connect to an external display Im watching yot tube when suddenly the screen appears white.pls help..and i found out also the camera and video have no display,just color white.whatg; Toshiba led tv only showing black and white picture.
