Any experience with M1 Mini and LG 32"-34" monitors?

[mlykke]

I'm looking to get an LG 32" or 34" monitor to go along with the M1 Mini. I've seen several people having issues with certain monitors, so I wan't to know if anybody has experience with one of the following monitors on the M1 Mini.

I'm looking at either the LG32UD99-W, LG32UL950 or the LG34WK95U, so I'd appreciate any input if you have experience with this combo and how you have them connected.

Got a 32-inch Samsung 4K monitor with the M1, and it's fantastic, with no issues, if that helps. Price is good too.

I have M1 MBA connected to LG34WK95U. Prior to MBA I was using it with 16" i9 2019 MBP. I don't have any issue using this monitor, and thunderbolt 3 connection is really convenient. But is there anything specific you want to know? Happy to answer your questions.

Specifically if it will run at 60hz when using the TB3 or displayport connection. I've seen some reviews of the BenQ PD3220 only connecting at 30hz unless you use HDMI.

Yes.

Retina resolution maxes out at 3008 x 1269, which is... well, usable, but it would be nice to have higher retina resolutions.

60Hz is easy. I was also able to get 2560 x 1440 @ 120Hz (connected to LG CX) as well, but that seems to be the upper limit (i.e.: it doesn't look like M1 supports DisplayPort 1.4 or HDMI 2.1 currently).

I found this on B&H for $300:

32" LG 32UK550-B 4K UHD 60Hz VA FreeSync LCD Monitor​

Is that a good display for the M1 ?

Can you give a little more detail, you say it maxes out at 3008 x 1269 ..
But you also suggest its working ok
thats not the native way that panel should work right ?
it should be native 5120 x 2160 which should be 2560x1080 looks like, no ?
or are you using it at a scaled res ?
Can you run it at the actual HIDPI resolution, so that it looks like "2560x1080" ?

 

[acantril]

And for the OP - it's BenQ monitors causing many of the issues
I have a 32inch (PD3220U) which should do 4k @ 60hz, which is can do on HDMI on M1, but on DP/USBC it only does 30hz. No single cable with that one

Yeah, I should clarify.

Scaled resolution for this one maxes out at 3008 x 1269. In fact, it seems no matter the monitor, scaled or HiDPI, it maxes out at around 3008, or 6016 pixels, across.

On a 16" MacBook, I also get 3360 and 3840 scaled resolutions (6720 and 7680 respectively). It seems M1 does not support a framebuffer greater than 6016 pixels.

But of course, HiDPI resolution works. It's 5120 pixels across after all. I just don't like it as much as 3008 or 3360 scaled resolutions because the others give far more screen real estate.

Can you confirm the 'looks like' resolutions you get in the display panel
its really unclear from your reply how this aligns
The resolutions you are listing are not for a 21:9 screen....
this one "3008 x 1269" for instance is what I get with a standard width screen.
and you are replying to someone about the 21:9 screen.

 

[bill-p]

Yeah, this isn't the first time that I have been asked to clarify this. I guess I'll lead with these screenshots the next time:

On M1, 3008 x 1269 is the max (and only?) scaled resolution, aside from 5120 x 2160, which is native.

But on my 16" MacBook Pro, I do get more scaled resolutions beyond 3008 x 1269.

The loss of screen real estate is pretty significant compared to the other higher scaled resolutions.

And 3008 x 1269 is 21:9. I think you're confusing it with 3008 x 1692, which is the 16:9 counterpart.

I am, you're right and thanks for the screenshot.

Is that with the 27" LG UltraFine 5K display?

Would love to see if it's the same resolution options available on a 32" 4K display. The resolutions seem very weird.

That's the LG 34WK95U. They're weird because they are roughly 21:9.

Though... I've heard that the same thing applies no matter what display you try. Scaled resolutions just top out at about 3008 horizontal (or 6016 in the buffer). For a 32" 4K display that's 16:9, I think you'll top out at 3008 x 1692 scaled resolution. That's what I'm seeing when I connect my M1 to LG CX.

Yeah I've checked in these forums with people running both the Apple 6K XDR and the LG 5K, both report that the 3008 scaled horizontal resolution is the max that the M1 can handle. It's tricky branding as the M1's do "support" the 6k displays, but at a much poorer quality than the Intels previously. For 90% of people this isn't going to make a difference but for those who have invested in anything above a 4k display its a bit of a disappointment.

Anybody having the problem should really let Apple know, so it can be fixed. This is definitely not something that we want to happen in all future M series Macs.
