Hello, I have a toshiba laptop under windows 10 and Im trying to connect it with an old flat LG tv via VGA cable but i get black screen on tv. i pressed winkey+p to display the second monitor and its ok, the cable its ok - tried it to another tv - but the lg shows nothing. it has only TV/AV1/AV2 input and none of the two AVs show the laptop's desktop. My drivers are all fine. When i connect the laptop to the other tv, in the monitor settings i see it also recognizes the device as Sony Bravia Tv. with the LG though, it shows it has a second monitor on but doesn't recognize with its brand name... if that has something to do with it. The tv also has a scart output but i dont have a cable atm so im only with the vga.

Thank you :)
