M1 MBP & LG 34 inch ultra wide 5K2K

[grmlin]

I’m sure all the people buying and loving Ultrawides simply don’t know better. Just use a small 16:9 screen from Apple and all your problems go away. If I had only known before. Damn


One of the weirdest nonsense takes I read for a long time in this part of the forum.

Unfortunately I don't have any additional monitors to test/check for you. That said, my guess is "yes" that should work but obviously safer to wait until they ship.

Let’s say I were to buy an M1 Pro or Max MBP today. Would my setup work? Correct me if I’m wrong, but I was thinking after I posted that it should since the M1 pro/max can drive two 5k ASD’s.

But the question remains: based on other’s experience, would I get weird scaling differences between, say, a 40” 5k and 32” 4k? Or would MacOS force the 40” onto a lower resolution to accommodate the 32”? I know from the thread that the MBP’s can run 1620p on a 5k2k, but something tells me that would not be possible on a 4K.

Because the iPad Pro is very expensive and doesn't run macOS. If size is all it was about hell why not wear clown shoes, which also happen to be extremely ultra wide? Come on. Only because a display is comically large and impractical doesn't mean it's better.

Yeah, adapt your needs to what Apple offers or buy a PC. You can't complain about the missing Mac integration, when you buy from somewhere else. There will always be an even-wider widescreen and an 8K+ display with yet more K's. That's the game of OEMs. You can chase after the spec race or you trust that Apple will pick the right screen size and ratio and pixel density and release a great integrated package whenever it's ready.

Speaking of clowning

Exactly. Funny too - when there's a new high in low, that's really saying something for places like this.

Yup that's why I said I *think* it should work. But for sure not positive, and for sure not clear about the scaling. Sorry can't be more definitive.

Ok, thanks. Hopefully someone else has tried and can weigh in.

Please can someone help me!

I have the LG ultra wide 34WK95U with M1 macbook 2021, and it was working breeze in clamshell mode in the correct 5160x2160 resolution. This was all up until I connected the M1 macbook pro to my samsung TV via HDMI.

Since doing so, thereafter, I then tried to plug in my laptop via thunderbolt to my LG monitor in clamshell, and the resolution was all strange. I then tried to play around with different resolutions to find one that was appropriate as 5160x2160 was no longer showing in my display settings. i then landed on a resolution that was clearly incompatible with the monitor, which turned the macbook to sleep and the display went black saying "no signal. Since that day, my M1, MacBook Pro has never worked in clamshell mode with my monitor. I have updated the Mac to the latest software Ventura, yet still whenever I try to plug in my laptop with the thunderbolt in clamshell mode, the monitor screen will flicker on for half a second (in a weird stretched out resolution) and then turn off and say "no signal" as the laptop goes back to sleep.

Since clamshell mode no longer works with my MacBook Pro on my LG monitor, I am forced to use the laptop as a mirroring display. However, I am now no longer able to even use the 5160x2160 resolution as when I click on display settings the best resolution available is 3440x1440 (See attached).

Can someone advise what has gone on? I can only assume that when I plugged it into the Samsung, it affected some settings within the Mac and it has meant I can no longer use clamshell, or ever use the correct resolution with any other monitor. I just don't get it?

Do the M2 Airs work with any of these 5K2K monitors? Looking primarily at the scaled options, 3840x1620. I know M1 Pro/Max offer this option, but the M1 does not.

It appears that it does not work on the M2 Air either.

I can confirm it does NOT work with the M2 Air.

I know it's a long shot, but have you tried BetterDisplay (link here) to create a custom HiDPI resolution for your monitor?

Yup. No joy. Apparently the non Pro/Max chips just can't render above some horizontal threshold between 6k and 7840. Not sure what the exact limit is.

In case it helps somebody, I wanted to chime in to say I use BetterDisplay on my M2 Air to run a 5K2K at 3840x1620 in HiDPI (although I prefer 4010x1692, which also works).

Natively, my options are: 1600x675, 2048x864, 2560x1080, 3008x1269 and 5120x2160.

Maybe your display preferences are messed up. Can they be reset by deleting them? I don't have an M1.

Hmm. That's really strange. I could not get BD to get 3840x1620 HiDPI on my wife's M2 Air. That said we got it pretty much the first day they were available. So maybe one of the minor interim updates made this possible? That doesn't seem likely but obviously if you're getting the resolution with the M2 Air then something is off about my attempt. I'd say it was the DP cable except it works with my M1 Max.

Hi
What about the 3360x1417 (or 3360x1418)? Do you have it and does it looks good?

Today I am using 3360x1417 hidpi on 5k2k monitor with 2020 MBP (intel) which works amazing out of the box. I really want to move to MBA M2 but am a little afraid with compatibility with my monitor (dell u4021qw)

 

[eric09]

Yeah, it works (similar to on my M1 Air, every even-numbered resolution pair seems to work fine).

 

[avicohenproblem]

Hi,
Thanks for your reply.
- I have never used BetterDisplay so maybe it is clear from the image you upload but still can you please confirm the screen actually runs at 5k2k and the m1/2 uses hidpi?

- does it work without BetterDisplay?

- do you see any performance issues?

My work machine is an M1 Air that I got a few months ago and I have an M1 Pro 14" as a personal machine, but I haven't been able to make the M1 Air my daily work driver as a result of this scaling limitation. I just installed BetterDisplay on the M1 Air running 12.6.1 and I am able to see all the hidpi resolutions on my Dell U4021QW. 3840 x 1620 looks identical to what it does on my M1 Pro 14" but the default 3584x 1512 seems to be the sweet spot for me. That's pretty close to the 150% scaling setting that I use on my Windows machine (which I can now turn in, since I won't need it anymore). No performance issues that I can see so far using BetterDisplay, and this is the only way I've been able to get these options on the M1 Air.

How do you like the Dell compared to, say, the LG 40” ultrawide?

- Do you see any side effect using BetterDispaly? For example, do you need to reconfigure the settings everything you disconnect the mac (which happens daily in as I connect it to the office screen in the morning and to my home screen at night)
- Do you use the extended options accessible via BetterDisplay or do you use the "Dummy mirroring" option?

 

[eric09]

@avicohenproblem Sorry about the delay! Was traveling and then forgot to follow up.

I have never used BetterDisplay so maybe it is clear from the image you upload but still can you please confirm the screen actually runs at 5k2k and the m1/2 uses hidpi?

Here's a screenshot of the readouts you showed in yours:

- does it work without BetterDisplay?

It works, but without BetterDisplay, the only resolution options I get in System Settings are the ones I listed in my earlier post (1600x675, 2048x864, 2560x1080, 3008x1269 and 5120x2160).

- do you see any performance issues?

Occasionally (I think if I let my display sleep and then wake the machine up again), I'll get a somewhat jittery cursor, but quitting and restarting BetterDisplay fixes it. You can find others reporting this in the GitHub discussions.

Do you see any side effect using BetterDispaly? For example, do you need to reconfigure the settings everything you disconnect the mac (which happens daily in as I connect it to the office screen in the morning and to my home screen at night)

I don't think so, beyond what I mentioned above? To answer your specific question, no, it remembers all the settings when unplugging & replugging—works great!

- Do you use the extended options accessible via BetterDisplay or do you use the "Dummy mirroring" option?

I use the latter. Dummy mirroring option is the only method I've gotten to work for me at the resolutions I use (3840x1620 and above), but here's more information from Istvan, the developer:

Unfortunately entry level M1 and M2 configurations do support a max. horizontal HiDPI resolution of 3072 with native smooth scaling (for 3840 you’d need M1 Pro/Max/Ultra). See the limitations here: https://github.com/waydabber/BetterDisplay/discussions/735

If you want 3840x1620 on the Air (M1 or M2) you currently have no other option than using dummy mirroring I am afraid.

This is a macOS limitation and it indeed hits hard ultrawide users.

Hope this helps!

 

[avicohenproblem]

Exactly the info I needed.
Thanks!

 

[dilinger]

Does anybody know if i can put an LG monitor desktop stand to my Dell U3223QE ??
I got space issue and the Dell Stand is too tall, whereas LG is telescopic.

Thanks!

 

[dilinger]

Are there any current 34wk95 owners here?
If yes, is it possible to measure please the height of the stand when sitted in lower position???
many thanks

 

[grmlin]

The upper end of the stand ca 28cm, the screen ca 44cm.

 

[dilinger]

wow i thanks it’s exactly what i needed.
my desk has a 30cm “nest” in front and i d like the back of the monitor to nest there…
is this the dimension you measured?

 

[grmlin]

Hope this helps. I would not want to use the screen that low though

 

[Robdmb]

A little off topic, but has anyone heard anything about a replacement to this model. Seems like its been out for a long time.

@eric09 As of 3840x1620. The BetterDisplay also has HiDPI desktop using native smooth scaling. Have you tried this approac with M1/M2 chip? Maybe there will be more options Natively?
Here is the link with instructions of how to to that: https://github.com/waydabber/Better...ith-betterdisplay-using-native-smooth-scaling

Looking forward to see a screen (or photos will be even better) if/when this approach worked…

I’m considering to buy LG 34BK95U-W UltraFine 34…

View attachment 2126546 Hope this helps. I would not want to use the screen that low though

thank you so much!
my desk is a little high so i set my screen to lower setting….
but i have no experience with lg height.
i think dell monitors sit higher in their lowest position….
when you got time could you measure please the height of the upper point of the ball ring behind the screen?
on the left to where your measure is..
i would need to “nest” the screen at the back of my desk…. it has a nest with a height of 30cm
