Optiplex 3000 Micro PC HDMI 2.0b Option Card
I'd like to add HDMI 2.0 4K monitor support using an internal Option Card for my Mini form factor Optiplex 3000 (onboard HDMI only supports HD resolution).
Can anyone supply the correct part number for this card and cable?

@Chino de Oro Many thanks for the part number and link, unfortunately Dell UK do not sell this part, and Dell US don't seem to ship to the UK.
There are also noine currently available on eBay in the UK.
Do you know if there are any other HDMI Option cards compatible with the OptiPlex 3000 that I may have a better chance of obtaining? (I've seen some 01KNYY and H6HFK cards here)?

You can source from Amazon UK here https://www.amazon.co.uk/Deal4GO-Daughterboard-WX01J-Replacement-Precision-Green/dp/B0DJ6NPX61
Or, you can get USB type C from Dell https://www.dell.com/en-uk/shop/dell-type-c-i-o-daughterboard/apd/cpl-gmhy5/controller-cards. Contact Dell Spare Parts UK and verify if that USB-C daughterboard support UHD video when connecting to monitor using a USB-C to HDMI adapter cable.
