I agree with @grmlin that the most frustrating part is the inconsistency. I'm lucky in that I have it on my M1Max MBP, but I'm eyeing the new Air for my wife and I'd sure like to know if she could use a 5k2k with 3840x1620.

If I understand the issue correctly, it's the way macOS scaling works, and that it's too much for the M1? It first interpolates the image to 2x of the target "resolution" and then scales it down to the scaled resolution using fractional scaling.

so 3840x1620 * 2 = 7680x3240, which means 24.883.200px
6k is less than that, 6016 × 3384, which means 20.358.144

But I'm also confused by this thread, as some people reported that it's working on their M1s, others used every trick and app without success. It's a very annoying issue, that's for sure.
Yeah, but what if you're saying is true, then that means that scaled resolutions above 3840x1620 aren't available on 6K monitors, which seems dubious considering that almost no one would be running a 6K monitor at its native resolution since the text elements would be too small.

Latest 12.4 seems to have fixed this issue. I now have 3840 x 1620 back without the hack.

Edit: looks like someone previously posted it but just thought I'd re-iterate. :)

People use 3008x1692 HiDPI mode on 6K display. It is native 6K. HiDPI just means objects are drawn twice as wide and twice as tall as usual. There is no interpolation or scaling when the HiDPI mode exactly matches half the width and hight of the native resolution (6016x3384 in the case of a 6K display).

The problem is that people would like to use HiDPI modes between the half way point (3008 in the case of 6K) and the full res point (6016 in the case of a 6K display) such as 3840x2160 HiDPI (in the case of a 6K display) which would require scaling down 7680x4320 to 6K. This has always been supported on Intel Macs but not always on M1 Macs.

I don’t think a M1 can scale the 6K screen like this. It’s 2x or 1x and maybe some other resolutions?

I wasn't aware that there was a limitation on the M1's ability to scale relative to other Macs (by "M1" I assume you mean just the base variant and not the Pro/Max/Ultra). Anyway, I plan to buy an M2 MBA soon after they're available, so I'll give it a try with my 5K2K Dell and post my findings.

Yes, base M1/M2. The M1 Pro and up support more than one 6K screen (M1 Pro two and M1 Max three), so I guess they can use higher resolutions internally?
It's also very possible, that it's just an artificial limitation made up by Apple to sell us the Pro models. Who knows

It’s likely an artificial limitation. Why give the base M1/M2 the ability for higher/multiple resolutions?

LG is great.
But does the MacBook Pro M1 MAX(all-in) support the:

49" Odyssey Neo G9 Gaming DQHD Quantum Mini-LED Monitor???​


What to do when it doesn’t work?

Do you believe LG is better?

That's not a hidpi screen.

No idea how well it works with a Mac though

I think you would just run this monitor at native display resolution and scale. At native size its two 27" 1440p monitors.

On paper this looks like one of the greatest monitors ever, but everything I have seen online is that there are significant issues and that it doesn't live up to its potential.

It's probably pretty cool for gaming? No idea why I would use a blurry screen like this for anything else though these days. (personal opinion of course)

You don't scale this screen (which is the issue with the M1). You use it at it's native resolution.
Yeah, I have Dell U4919DW 49” 5210x1440. Works great with my Mac via USB-C to DP cable. I’m sitting about 80cm from it and from that distance fonts are OK. Amazing horizontal space for DAW use. I’m using it natively, 5120x1440 - no scaling.

I'm still having issues on 12.4...M1 Pro 14 inch with LG34WK95 5K2K....

I've been using 3440x1440 the last pst couple months... I have a suspicion it's got do with the monitors EDID not being correctly detected but have no found fix

Don't use Display preferences to list modes. Use SwitchResX or similar since Display preferences panel might skip some modes.

I'm asking me the same thing. I would really like to know if the M2 MBA has the 3840x1620 scaled resolution.
Actually, I've thought about what the definition of fair is with respect to this specific issue we have all faced, particularly, in light of all these rumored new offerings. I'm wondering now whether the M2 MBA will feature 3840x1620 scaled resolution.

Got today my LG 40WP95C-W monitor as I was tired with all the (wakeup) problems I had with the 34WK95U 5k2k display. What should I say: The 40WP95C is fantastic. It works on a Macbook Pro 14 with M1 Pro via Thunderbolt and Displayport Mode 1.4. With the 34WK95U it was only possible to use DP 1.2.

As the 40WP95C has the same Pixel amount as the 34WK95U the picture/pixels are slighly bigger (not visible/noticable) but with a major benefit: You can use the scaled resolution 3840x1620px without an issue reading texts while havin a lot of real estate on your desktop. This scaled resolution was just not possible to use on the 34WK95U as everything was too small. Terrific!

But boy, that monitor is big. I have it mounted on an Ergotron HX but it's soo big, you really want a little distance between you and the monitor :D. I can't confirm if all the wakeup issues have been solved yet as I'm just playing with the display, but so far it looks good. The 34WK95U also had issues with a wrong resolution during wakeup. Not noticed anything similar with the new one.

Just wanted to provide that feedback as not many people provide these insights.

Wouldn’t it be better to buy the LG 49-inch ultrawide?
Or the LG C2 42-inch evo OLED TV https://www.lg.com/us/tvs/lg-oled42c2pua
Or the LG CX 55 inch Class 4K Smart OLED TV w/ AI ThinQ® https://www.lg.com/us/tvs/lg-oled55cxpua-oled-4k-tv

Thanks for sharing! I agree 3840x1620px on the 34" is too small. On the 40", care to share whether the text at 3840x1620 is crisp / clear?
