I am trying to conent to a an Acer projector (i am unblable to get model) in my university. The projector is connected with a LAN cable to an extender where the users connect using VGA port. As a lot of us a new Pc that only has HMDI port we buy an adapter ( https://www.extrastar.es/product/adaptador-hdmii-macho-vga-hembra-cj192/) that work for all less than for me. When I connect the adaptor is recognized (i see as diplay) but the projector don't receive any signal. The strage think is that i use the same adaptor to connect successfully to a VGA monitor.
I just try the following soliution without success:
1)update all drivers
2) unistall and reinstall video and monitor drivers
3) changing resolution
4) switching disply setting using f4 or win+P keys
2) Click on Sign-in or select the product using the below step:
