I'm not sure if it was or was not. I ran it as far as I could from other cables without any luck. On my monitor the OSD is also doing it which leads me to believe it's the monitors fault. The store where I bought mine form only has the PG279Q in stock. I don't know if they do straight replacements or if they'll send it to Asus but If they do I'll aks for the PG279Q and pay the difference. I hope they accept that
