Multi monitor audio desync

[jamiewwer1]

hi I have a problem with my monitors and playing videos.
I just added a new monitor to my setup. but....

When I start a video the audio and video will be in sync but slowly over time the video wil start to lag behind the audio. This happens both in online and local playback.


My setup is:
1 dell monitor displayport
1 smal tv hdmi
[new] 1 dell monitor DVI-D <-- this one started the problem.


PC:

I7 6700K
GTX 1080

Any ideas?

I think the audio inside these displays aren't the same, so you wont be able to get the same sound quality.
ADVICE: buy a set of speakers if you don't want any sound desync.
