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.

Don't know if the newer ones have this somehow worse but the problem was always just when VRR was enabled an in very specific situations.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. I have literally used the LG CX 48' as a desktop display for two years at 4K 60 Hz on a Mac. Until Apple fixes support for HDMI 2.1 there is nothing you can do. There is still absolutely no way to run it at above 4K 60 Hz and even that requires EDID hacks if you don't want it to default to 10-bit 4:2:0 which is the absolute worst option for desktop use because it makes any red/blue text look like garbage. I think I have seen it in a game loading screen when using it on my desktop PC at 120 Hz but again, it's a rare problem.īut when it comes to Mac, just don't buy a LG OLED TV to use with it. So they are likely to have the exact same problem.Įven when gaming on the CX using a PS5 where most games run at 60 Hz, I have not experienced this flicker issue a single time. The problem is specific to LG OLED panels too and if it's a 42 or 48' model, at the time of writing every other manufacturer will also use LG OLED panels for those sizes.
