RX 550 secondary GPU video stutters and audio lags

Question asked by firedrops on Dec 11, 2019

I have a PC with 3 monitors:

1x Primary monitor driven by RX 5700

2x Secondary monitors driven by RX 550

 

Other specs:

R5 1600

2x8GB 3200mhz Trident Z ram with 1usmus safe timings

 

If I move the video window (i.e. youtube on chrome/firefox/opera) to a secondary monitor, it is unable to keep up and begins stuttering at 1.5x speeds and above. The audio also gets desynced soon as the video doesn't keep up and it looks like audio is played earlier than the video frames. The desync is immediately fixed if I pull the window back onto my Primary monitor on RX 5700.

 

I know the RX 550 is a relatively weak GPU, but it should not be struggling with basic video playback tasks that even igpus from ages ago are competent at, so I believe this can be improved in software.

 

Is there anything that can be done on my side to improve this?
