Hi All,
I have an apple 30inch display with the CAC 1510-A adaptor to turn it into USB C. This is great for my windows laptop, but i also have a gaming PC.
How do i connect this to my gaming PC?
my gaming PC has 2 outputs – HDMI and Display Port, with an Nvidia Geforce GPU.
I have tried a UCB-C to HDMI adaptor but the screen isnt recognised and does nothing.
Do you mean HDMI to USB-C adapter? (since you have an HDMI output and need a USB-C output to connect the USB-C input of the CAC-1510). I’m not sure if USB-C adapters like the CAC-1510-A can work with HDMI to USB-C adapters.

HDMI to DVI adapter could work but only for DVI single link mode 1280×800. HDMI to Dual Link DVI adapters are usually just cheap passive single link only adapters. You need a dual link adapter like the CAC-1510-A to get 2560×1600 on a dual link DVI display like the Apple 30inch.
Your gaming PC needs a USB-C port that support USB-C DisplayPort Alt Mode for the CAC-1510-A.

Or you could get a DisplayPort to Dual Link DVI adapter like the CAC-1010-A.

Did you check the EDID of your Apple 30inch to verify that it doesn’t have HDCP? If it has HDCP, then the HDCP ON versions of the adapters might be better (for displaying content that uses HDCP). Old Apple 30inch displays don’t have HDCP. Later ones do.

Notes about the Synaptics VMM2320 based DisplayPort/USB-C to Dual Link DVI adapters:
