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.
"The hackers gained initial access using a stolen account credential that lacked multi-factor authentication security, according to UnitedHealth."
Absolutely unacceptable. I might be easier to forgive them if some zero day was used, but that's so easily preventable.
That account presumably had some level of privileges, the policy should have been to enforce MFA, and if the account was inactive, disable it until the user needs it at which point set up MFA again.
