Hi ! Thanks if anybody have a clue or a solution and sorry for my bad english I'm not a native speaker.
I'm quite a newbie here but I've been looking for a solution to this problem :
I've got a terrible ground loop sound when my asus screen is plug with the display port, and when I unplugged the display port cable sound is gone (but there's still a really low with noise when my preamp is set really really loud)
Quite all my cable (expect for the 3.5 to RCA) are really good quality cables.
Here's my setup :
I''ve also have micro stuttering when using youtube or things like that. I've checked latency and performed quite everything I could fine to lower it and now I don't know what to do...
Here my complete configuration :
Here a some latencymon results :

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.
Highest measured interrupt to process latency (µs): 330,90
Average measured interrupt to process latency (µs): 5,748012

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.
Process with highest pagefault count: microsoft.photos.exe
Total number of hard pagefaults 8796
Hard pagefault count of hardest hit process: 3163
