It was a 12″ monochrome (green) screen that could display 80×24 text characters and any type of graphics, however it suffered from a very slow phosphor refresh that resulted in a 'ghosting' video effect. However, in order to offer complete systems through its dealers, Apple began to offer various third party manufactured 12″ monochrome displays, re-badged as the Monitor II.Īpple's manufacture history of CRT displays began in 1980, starting with the Monitor /// that was introduced alongside and matched the Apple III business computer. In the beginning (throughout the 1970s), Apple did not manufacture or sell displays of any kind, instead recommending users plug-into their television sets or (then) expensive third party monochrome monitors. To connect a display with mini DisplayPort, you need one like the USB-C to Mini DisplayPort adapter ( $34 on Amazon £25 on Amazon UK). Amazon sells the Cable Matters USB-C to DisplayPort Adapter cable for $18, or £30 on Amazon UK, and it supports 4K video at 60Hz.

To connect to a DisplayPort display, you need a USB-C to DisplayPort cable or adapter.

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. The display is still usable, but the flashing pixels are a distraction.Īpple has not addressed the issue, which seems like it could be a compatibility problem with the M1’s GPU. As detailed by Macworld, these displays show a line of flashing pixels at the top right of the screen. However, people online have reported problems with using the Thunderbolt Display or Apple’s LED Cinema Display with Apple’s M1 Macs.
