Very bad
Product to avoid, very bad quality for an exorbitant price, I am surprised that LDLC sells such a rotten product
On VR headset: causes snow on the image, with intermittent disconnections of sound and/or image
On 3440x1440 screen: good picture quality, but intermittent picture disconnections
I replaced this with another cable for 5€ noname, it works much better, I think I'll run away from this brand of cable like the plague.
