Question ‘No signal’ display using mini displayport

[huki]

hi so i am using a macbook pro 2011 running windows 10 through boot camp. i’m trying to get my mini displayport to hdmi adapter to give a signal on my Acer h236hl, i’ve tried; updating graphics drivers & display drivers, uninstalling them and reinstalling them, turned off fast start up, switched cables, used on a different pc, and more.
but nothing has worked for me thus far. i know the dongle isn’t broken because when i tried it on the macOS side the display worked.
my macbooks display on windows 10 is labeled as ‘generic pnp monitor’ and i believe my Acer h236hl would be one too, how do i fix that so it recognizes ?
i’m not sure if this has to do with running windows 10 through boot camp.
sorry if this question is confusing but i really want this to work and i need help.

Is it a thunderbolt port?

Are you using the sync mini adapter to hdmi? And I'm not trying to insult your intelligence, just ruling things out, did you plug the monitor in to your mac while it was off?

this is the adapter i am using

i’ve done it while it was off and on just to reset the connection but nothing worked

ok so try the connection to a tv and see if it recognizes the tv. If it doesn't then you have a cable problem. Either the hdmi cable or the adapter.

 

[huki]

they both work, it’s just a problem with windows 10, when i switch to the macOS it works fine and i’m able to use it

LOL ok I sure didn't understand your question then. So your question is how do I get my boot camp win10 to recognize my monitor.

What drivers are used to power your gpu?

i have Intel (R) HD 4000, i’m not really into this but i’ve updated it automatically but not manually yet, on the intel website i can check what drivers need to be updated and there are none, intel says i’ve updated every driver on my computer

ok so try this trick see if it works, with the mac on and the monitor connected and on hit reset/restart on mac and close the lid on the mac. Let the mac go through restart with lid closed and see if the monitor gets a signal. If it does then simply open the lid and it should go dark for a second and both screens should work.

hey sorry i just got home to test this, my monitor lit up and the windows logo appeared but went dark, i opened the lid and it went completely black and back to no signal

 

[Fix_that_Glitch]

ok so with computer off, press power up button and quickly close the lid, and see if it works that way.

 

[huki]

nothing, only worked that one time now it doesn’t even light up or anything

 

[Fix_that_Glitch]

Did you check to see if it recognizes the monitor?

 

[Fix_that_Glitch]

Try turn them both off, then turn on monitor, then power on pc and close the lid.

 

[huki]

ok it is dark i can mess with its settings but there’s no actual display

 

[Fix_that_Glitch]

Ok, I am out of options for you sorry. The only thing would be to turn them both off, turn on monitor, then turn on pc, hit reset and close the lid quickly, wait to see if monitor has signal.

BTW, what graphics drivers did you download?
