Question: Apple M1 MacBook Pro - External Monitor Resolution

The specs show that the new M! MB Pro can drive "one external display with up to 6K resolution at 60Hz." My question is whether that can handle a 49-inch super ultra-wide 32:9 at 3840 X 1080 native, because I can't tell if it could handle two displays at 4k.


Thanks for any help in advance!

I have the LG 49" Ultrawide Running Native 5120x1440 @ 60hz This monitor is a 5K so theoretically it should work. Until they hit the street or someone with one of the Developer M1 machines that happens to use on of these monitors tries it for real we won't for absolute certain but I feel good about it.


I have an older 2017 MacBook Pro 15" which can intermittently run this monitor at full res. So I'm strongly considering the MacBook Pro 13" M1 loaded.


Random Brain Dump

I'm used to the iPad Pro Workflow so the fact that I can have my 49" Ultrawide, iPad Pro Apps + Sketch and full Adobe creative suite handy is attractive enough to make me consider early adopting which will buy me time until they refine it more or I skip the entire transition all together and just but a bigger MBP when it goes big time in 2 years, but my workflow is mostly photo and 2D design and I have a loaded ZenBook Duo for video editing if necessary. Though I've considered going to FCP.


Anyway that's my 35.7¢ of random brain dump no one asked for regarding this topic lol ;)

There's a HUGE amount of doubt on the message boards about the M1 being able to run a 46" UltraWide monitor at 5120x1440 resolution.


I have a Samsung 46" UtraWide monitor and have been holding off buying the M1 Mini because I have read issues about these monitors having scrolling issues and not being able to run in the native resolution.


My 16" MBP works fine with my Samsung 46" UltraWide monitor at 5120x1440.


I do have ScreenResX installed.


This is my connection:


MBP -> 4k 60Hz TB3 cable (40Gbps) -> Caldigit Dock -> Display Port Cable -> Samsung Monitor


With that connection is there any suitable resolution I may be able to obtain with a Mac Mini M1 connected the same way?


I am hoping, once and for all, someone with an 46" Ultrawide monitor can let us know if these M1 devices can properly drive them.

I have a LG ultrafine 5k thunderbolt display which has a higher resolution than your monitor does because its real 5k resolution. I also use an elgato thunderbolt 3 dock


if your displays are just display ports from a thunderbolt 3 dock then you won't have any issue with 2 displays.

there is not therory about it when it scomes with just display port or usb c monitors, you are only restricked to one display when you start going for 5k 6k or 8k monitors when I say 5k I mean REAL 5K resolution not ultrawide resolution which isn't real 5K. like the LG ultrafine 5k thunderbolt display.

The question was about the M1 notebooks, which only support one external display.

I'm sharing this in the hope it helps a lot of people. After hours of trying to work this out and starting a return for my M1 MacBook Air, I've got a solution. I'm using a 49 inch super ultra wide monitor and simply couldn't get it to work at all, not even acknowledge a monitor is even plugged in, it works absolutely fine on my 16 inch 2019 MacBook Pro. The solution after hours and hours was to switch the setting on my monitor down to Display Port version 1.2 from 1.4, once I did this I could finally get an image albeit not at native resolution for the monitor. Once in Display Port version 1.2 at least with a low resolution image (I was getting nothing before), I could then use SwitchResX and FINALLY it would see the monitor so I could increase the resolution up to 5120X1440 @ 120hz, and all is FINALLY working fine. What a serious mess, and wasted days trying to get the M1 to even acknowledge a 49 inch monitor but finally this is a solution that works.


Please don't ask why, I still don't know but at least it's a solution. Possibly something to do with Freesync on the monitor, maybe the cable? Clearly it's something though with the M1 as my other Macs all pick up the monitor automatically all using the same cables and the monitor on display port version 1.4, anyway switching it down to 1.2 then using SwitchResX has solved it.


What do I win? lol

I have the same questions myself, I have the LG 49WL95C-W 49-Inch Curved monitor and had to buy the MacBook Pro 16-inch 2019 so it would work. This was due to the Iris Graphics card not supporting this resolution.


Do we know if the smaller MacBook Pro 13 M1 or Air M1 will work with this monitor?


It needs to support 3840 x 1080


Any response/knowledge would be greatly appreciated.

Yes i connected the same LG 32x9 49" monitor (model 49WL95C-W.AEU) on M1 MacBook Air it recognised the monitor and switched to the default 3840 X 1080 resolution fine but the native panel is 5120x1440.. however if you OPTION-Click on the dot on "scaled" you get all possible resolution including the 5120x1440 although it mentions that is is "low res"... that is incorrect the image is perfect since it is not scaled so full native for me !! somehow Apple does not correctly detect the native resolution. And it was running Lid open driving both internal and external monitor, and can also be used lid closed.

Hi, what you can tell about temperature of MacBook Air with 49"? Is it comfortable for MacBook Air to works with this monitor?


I want to buy the Samsung Odyssey G9, and I'm interesting, will can the MacBook Air / MacBook 13 M1 works with it ( only for coding ) without throttling or overheating


Thank you for your answer :)
