Who is at fault Club3d or Nvidia? Product Name: DisplayPort™1.4 to HDMI™ 4K120Hz HDR Active adapter M/F Product Series: Adapter Itemcode: CAC-1085 EAN code: 8719214471538 UPC code: 841615101726 Features: • Compliant with VESA DisplayPort™ v1.4 Specification • Compliant with HDMI™ v2.1 Specification • Support HDCP 1.4 and HDCP2.2 • Support DSC v1.2a and backward compatible with the former version • Support Max. resolution/refresh rates up to 4k@120Hz • Support Dynamic HDR • Sound Support 5.1-7.1 I used to be able to watch netflix on my 4K@120hz desktop on my lg C9 and club3d cac-1085 dp-hdmi2.1 adapter. Ever since v451.67 or later things have gone downhill for the 2080ti and this adpater and lg C9. The latest nvidia drivers won't even allow 4k@120hz through the adapter. (Some DSC changes?) Without this adapter I am stuck on 60hz. Who is making changes? What changes are they, and why? If the adapter is compliant with all the standards listed above, and only driver software changes are breaking the workings, then wouldn't that point to nvidia? This is ridiculous, all i wanted was 4K120hz and netflix to work without throwing hdcp errors. And to be able to actually get 4k120hz on the latest drivers. I paid a lot of money for this setup, now a few nvidia driver changes and it's all gone to crap.
