You can use a regular HDMI cable like the theĪmazon Basics HDMI cable ($8/£8 on Amazon) and plug it in. If you have the 14- or 16-inch MacBook Pro or Mac Studio, they have a full-sized HDMI 2.0 port. To connect a display with mini DisplayPort, you need one like the

£30 on Amazon UK, and it supports 4K video at 60Hz. Amazon sells theĬable Matters USB-C to DisplayPort Adapter cable for $18, or MacBook Air (13-inch, Mid 2012 & 2014): 2 x USB 3 ports, 1 x Thunderbolt port. To connect to a DisplayPort display, you need a USB-C to DisplayPort cable or adapter. Right side of MacBook Pro (Retina, 15-inch, Mid 2015): SD card slot, HDMI.

So there probably will be no fix coming from Apple. Apple declared these displays as “Vintage” in July 2021, which means that the company will not supply parts for repairs, nor do they promise to provide OS support. Apple has not addressed the issue, which seems like it could be a compatibility problem with the M1’s GPU.
