screen tearing Lenovo y520 RX 560 external monitor Acer R271


For some time I am experiencing typical scree tearing on my external monitor. It is Acer R271 27". During playing WoW and sometimes watching say YT vids the picture becomes "torn" going lines or areas in red, green, blue etc.

It is a link to footage of how it looks in game:

The monitor is connected via HDMI cable to Lenovo Legion y520 - full configuration info under the post. The video card I use is Radeon AMD Radeon(TM) RX 560. I did update to newest available drivers, it didnt help. I downgraded them to

Manager recommended version, it didnt work. It now runs on the highest available version.

I turned on Vsync in game and in the card settings, separately and in the same time, it didnt work.

I checked the cable connection on 3 different HDMI wires and it didnt work..

I tried almost (I think) available option.. which I currently ran out of

I would like to ask for lots of support.. both spiritual since I need it atm with that issue cause it drives me nuts.. and technical.. that would actually work!xD I am step away of turning monitor to the seller since its still on warranty.

Yet I consider this last resort.

So.. somebody.. something? And thank You in advance
