M1 MBP & LG 34 inch ultra wide 5K2K

Ultron said:
M1 Pro, Max, and Ultra can do it. I was under the impression you were asking about the regular M1 and M2, both of which can't.

Thanks!

Two more questions tho ;-)

1. So that ain't right for base M1 then ?

Maximum horizontal resolution = 6144 or 3072 HiDPI
Maximum vertical resolution = 3160 or 1580 HiDPI

I don't see much difference between 1580 and 1620... so technically that scaling should be doable on M1 base model.

2. With BetterDisplay one is able to achieve up to 99% of native resolution (low res) as HiDPI.
Woudn't it be better to run 99% of 5120x2160 as HIDPI ?

What is max to be possible for such monitor ?

Isn't 49' Ultrawide a 1440p, which by default ain't possible of HiDPI ?

I was able to get 5K1440p HiDPI (10Kx2880 scaled mode) with some Lilu/WhateverGreen patches on my Intel Mac mini 2018's Intel GPU. This proves that Apple may apply unnecessary limits to its drivers. They want you to buy a new Mac or they don't want to hear complaints about the mode causing issues (I didn't run into any issues but they may exist).

that is probably not possible on M1/M1 Pro/M1 Max, right ?

Only possible on 2018 or hack, right?
 
Just in case it's useful to anyone, I just got the M2 Air and I can run it in native res just fine...

(although I prefer 2x "Default" mode, and I can control the size of text inside the apps I use)

The options I see are:

Other than the 5120x2160 native res, all of the other options are HiDPI. There is no option I can see to have e.g. 2560x1080 in non-HiDPI mode.

While SwitchResX can't create custom timings for Apple Silicon (because Apple), it can probably create custom scaled resolutions such as 2560x1080. I would try that to see if there's any non-HIDPI modes.

This is actually the same issue that the regular M1 chip faced, and it's unfortunate to see that the M2 chip suffers the same problem.

Most people who buy the 5K2K ultrawide monitor prefer to run it a HiDPI mode that scales the effective resolution to somewhere close to 3440x1440 so that the text/UI stay sharp while retaining roughly about the same effective screen real estate as a conventional 34" ultrawide monitor with the 3440x1440 resolution.

To put it another way, none of the resolutions listed there are considered optimal because:
  • 5120x2160 (native resolution) makes the text/UI too small
  • 3008x1269 (highest available HiDPI resolution) results in a smaller effective screen real estate than a conventional ultrawide with 3440x1440. With this setting you're essentially trading your screen space for sharper text/UI
  • 2560x1080 or 2304 x 972 give even smaller screen real estate, so it doesn't make sense to buy such a premium monitor if this is truly all the screen real estate you need
For those who are wanting to use higher HiDPI settings, the only choices at this point are buying one of the higher tier M1 chips (e.g. Max, Pro).

For M1 it's 6144px vertically not 6016 wtf ?

It's 8k for M1 Pro ~7680px vertically.

M1 on 5k2k is looks too big in HiDPI .. not usable.
M1 Pro is the only choice but still we need 10k scaling maybe in M2Pro ?? Or that is too much to ask for ?

more space is not native .. it's still scaled probably.. 0.6 or 0.75 can u give ?

It looks native res to me. Everything way too tiny. Not sure how I'd check if it's not really native res. Surely if it says 5120x2160 and the native res of the monitor is 5120x2160, then there is no scaling?

Yeah you're correct. Running any monitor in its native resolution will give you the most screen real estate. There's no scaling involved when running in the native resolution. I think @macmus12 got it mixed up.

just put cursor above "more space" in display menu and grief screenshot.

No no .. nothing is mixed up... native resolution in case of 5k2k is working fine, however that is not HiDPI (x2 scaling to 10k is too much, check what are the limits I wrote above).

Right and you are not going to get HiDPI above 3008x1269 on 34WK95U using either M1 (non-Pro/Max/Ultra) or M2. That's just the limit as is.

I was just commenting to clarify that native resolution will give you the most working space (even though it makes text/UI too small to be usable).

What does "x2 scaling to 10k" mean on a monitor with a native res of 5120x2160?

It means having a 10240x4320 scaled mode to use a 5120x2160 HiDPI mode which is scaled down to 5120x2160 for output to the display. You won't notice much difference between 5120x2160 and 5120x2160 HiDPI modes since the display is only 5120x2160 but maybe the 5120x2160 HiDPI mode will have smoother text or more antialiasing or maybe it won't be as sharp.

You are correct, but native mode for text is terrible, HiDPI is the way to go always.

I've tested this with a macro lens, and HiDPI scaling has pretty much no effect on text rendering.

I see it on when scaling and using 2560x1440 HiDPI --> means 5k2k (on 2560x1440 monitor) with betterdisplay software.
I assume I would see it also on twice the resolution (Samsung g9, Lg 5k2k etc..). Need that 2x HiDPI scaling for text for sure.
 
I still don’t understand why text would be less crisp at a Displays native resolution than in hidpi. It’s too small to be usable but when zooming in in apps that support it, like a browser, I don’t believe there should be a difference.
I never heard of MacOS using different font rendering in scaled modes. If anything it gets less sharp due the the way Apple scales the UI when applying fractal scaling
