I have a problem with my laptop (model VN7-571G). After a recent Windows 10 update, now I am not able to connect the laptop to my flat LG TV via HDMI. I think it has to be related to Intel Graphics 5500 (current driver 10.18.15.4248). When I connect the laptop to my flat TV, laptop screen goes black (as it happened before), but TV message says "Without Conection". If I try to use Intel Driver Update Utility 188.8.131.52, it says I have to go to Acer website to get the drivers. I have already uninstalled all Intel drivers (VGA, chipset, etc.), and installed the ones in Acer website but the problem still exists. Any idea how to solve it?. Thanks and regards from Spain.
