I had Win 8.1 since I had this laptop. I had my TV connected via DVI since 8.1. When I upgreaded to Win 10 the TV was still working as a monitor. For some reason yesterday it stopped working. Before I go out to buy a new cord I was wondering if it could be something else I haven't tied yet. Any suggestions would be appreciated. I have read the other posts here but none of those ideas worked.
