Unfortunately, it looks like the 2013 Mac Pro video is at fault.

Appears to be temperature sensitive: too hot (perhaps 78☏ or warmer) or too cold (65☏ or colder).

PA322UHD with different MDP cable on the Mac Pro-same problems.

But on the MacBook Pro it has run for over a year without issues.

EA244UHD swapped to Mac Pro (same cable, same port): same problems.

PA322UHD swapped to MacBook Pro - no problems over several days.

Here is what I’ve done which now makes me think it is the D700 GPU in the 2013 Mac Pro is going bad (or new bugs in OS X perhaps?). And neither the late 2015 iMac 5K nor the late 2013 MacBook Pro Retina has any issue. But two displays? Using two cables (swapped for proper A/B comparison). Recently, the main display ( NEC PA302W) also occassionally blinks (loses signal) also, but only for a moment.Īt first I blamed the PA322UHD display. It comes and goes, working OK for hours, then becoming unusable for 15 minutes at a time. But usually just a blink-off to no signal, then back, then off, repeatedly for several minutes. My NEC PA322UHD 4K display (critical to my daily work) has been on the blink, losing the signal, making crackling noises from its speaker (though not always), discolored image (intense magenta and/or green), mangled image, etc.

In the examples below, not every display was running at 4K, but the workaround still appears very impressive.Ĭheck out the full videos below for exactly how he configured these setups. Also notable, he says he didn’t even see the Mac mini fan kick up during his testing. With his workaround, he shows the Mac mini running up to 6 displays and the MacBook Air running 5 external displays. Interestingly enough, he says the M1 Mac mini and MacBook Air he tested performed “awesome” overall under a heavy load playing YouTube videos and the highest resolution available and even using Final Cut Pro without dropping hardly any frames.

You can check out a detailed walkthrough of the setup in the videos below.

The workaround isn’t too complicated and involves downloading the DisplayLink software for macOS (Tulupov says works fine with Big Sur) and picking up a 4K DisplayPort to USB 3.0 adapter (and/or HDMI adapter).ĭepending on how many displays you want to run with this trick, you might need a USB-C to USB-A 3.0 adapter or a Thunderbolt or USB-C dock as well as additional cables, etc. YouTuber Ruslan Tulupov has shared two videos demonstrating the workaround he discovered (via MacRumors).

However, just like we’ve seen in the past when Mac compatibility with Apple’s Pro Display XDR was found to be broader than Apple says, it appears that M1 Macs can indeed run up to 6 external displays with good performance… at least in early testing. And the Mac mini up to 1 6K at 60Hz over USB-C/Thunerbolt and 1 display up to 4K at 60Hz over HDMI. In what looks like some exciting news, it appears Apple may be underselling the M1 Mac external display functionality.Īpple says in its tech specs the M1 MacBook Air and 13-inch MacBook only support up to 1 external display up to 6K at 60Hz. While almost all aspects of M1 Mac performance are greatly improved compared to the Intel Mac predecessors, one notable downside has been reduced support for external displays.
