MBP 2015 13 - Cannot connect to DVI Dual Link 2560x1600 display (aussie.zone)

Hi guys

I have a Retina MacBook Pro 2015 13 inch with 2.9GHz i5, with Ventura on it using OCLP.

I have a StarTech DisplayPort to DVI Dual Link Active Adapter (DP2DVID2) which I use with my 2560x1600 Dell monitor that only has a DVI Dual Link input. This adapter works flawlessly with my work laptop, a Lenovo ThinkPad L14 via a HP USB-C dock, but connecting it to my MBP (using another adapter going from Thunderbolt 2 to DisplayPort), the built in display goes blank for a second, and then comes back but there's no image or activity on my Dell monitor.

If I boot my MBP into Windows 10 via Bootcamp, it works totally fine at full resolution, and the same can be said for a live installer of Linux Mint. Booting into El Capitan, Monterey or Ventura does not seem to detect my monitor.

I've got a couple images of System Information in case it helps: one and two.

I actually originally posted this issue to MacRumors but no one replied to me at all, so I'm now trying this Apple community, but if this isn't the right fit then I apologise in advance and would like to know where I should post this instead.

I never had this problem, but i guess that one of the adapters(most likely the DP2DVID2) requires some drivers that are standard in windows and linux but not in macOS. maybe you can find the driver that is needed and look if there is a mac version. otherwise you are out of luck I think.
hope this helps

Thanks. On the manufacturer's website there's no drivers available but it does outright mention it is compatible with Macbooks (doesn't go into any further detail). I've already submitted a question to the product page and am awaiting an answer from them, hopefully they might give me something like a driver for macOS.

depending on the seller they indeed might send you some driver or help you solve the issue
