So when i try to add my 3rd monitor it either doesnt show anything or it duplicated my monitor and i cant seperate them

#

Even tho theres a picture on both it says that it doesnt detect another monitor

#

what GPU do you got?

#

And which cables do you use?

split prairie Apr 21, 2023, 5:07 PM

#

ive got a laptop

#

but its a 1650 max q

#

both hdmis

serene burrow Apr 21, 2023, 5:07 PM

#

so 2 output?

split prairie Apr 21, 2023, 5:08 PM

#

its a adapter from 1 hdmi to 2

#

but i think the problem might be that both monitors are hooked up to a hdmi output so the pc thinks they are both hdmi 1

serene burrow Apr 21, 2023, 5:08 PM

#

thats never gonna work, that will just duplicate the signal

split prairie Apr 21, 2023, 5:08 PM

#

hmm

#

#

serene burrow Apr 21, 2023, 5:09 PM

serene burrow Apr 21, 2023, 5:09 PM

serene burrow Apr 21, 2023, 5:10 PM

#

split prairie Apr 21, 2023, 5:11 PM

#

serene burrow Apr 21, 2023, 5:11 PM

split prairie Apr 21, 2023, 5:12 PM

#

serene burrow Apr 21, 2023, 5:14 PM
