MacOS BigSur - M1 support: works great, but it would be really helpful to have the "looks like 2560x1440" option available for 4K resolution
use now a DisplayLink capable hub to use an 2nd external monitor on a M1 MacBook..
works great, but on that screen I can only choose between "Looks like 1920x1080" or the full 4K resolution - which is not really good to read on that monitor.....
Would be really great, if the "Looks like 2560x1440" resolution (scaling of UI) would be supported in one of the following updates.....
Would be great to have HiDPI support for all display resolutions the M1 Macs support for the 1st external monitor
+1 would be great

Would be great. I'm not a fan of stuff being either gigantic or so small I can't see it and nothing in between. :( Still not working on 1.4.0
A proper "looks like 2560x1440" in the same way Apple does it would be really nice!
At the moment, we have a "2560x1440 (low resolution)" mode that makes everything look blurry.
The thing is, I have 3 identical monitors, all of them set to 2560 x 1440. The ones running natively look great, while the one via DisplayLink looks blurry.

Yes please displaylink add the "looks like 2560x1440 - the other 2 display resolutions are way too big or way too small on a mac mini M1 with 4k monitors! I had high hopes for the adapter I just bought but its just sitting on my desk now waiting for this to get sorted
@TomP its a limitation of using DisplayLink and/or Macos. There has been no answer as to if this is a displaylink issue or a limitation of macos. With displaylink you either have 1920x1080 FHD or full 3840x2160. This request has been outstanding since last year and no response so you can only assume that it will never happen. So there are no resolutions that displaylink supports above FHD with HiDPI. The only solution is to drop the displaylink dock and use a single monitor as this will typically give you the HiDPI resolutions that are missing. Unfortunately it does mean a single display. Thats probably not to much an issue if the 3840 text from the mac is not readable for you.

I am also using a Dell D600 DisplayLink Dock with my M1 MacBook Air and I have a 4k Samsung Monitor and a FHD Acer Monitor connected. My Macbook is showing me, that my 4k Monitor is only FHD and gives me no option to get the full capable resolution, eventhough all my cables are 4k capable. Now I am looking for the reason for this issue and maybe an update for display link can solve that. If anyone knows, what an other problem could be, let me know. Thanks
Ran into this problem as well. Really wanted to use an M1 MBP with my two LG 4K monitors but can't handle the small UI elements in MacOS at native 3840 x 2160. Hoping this feature will be added soon.
What a great idea! Displaylink obviously get more revenue form the hardware licensing than the drivers. Opensource the drivers and let the community drive some of the development to boost the sales of the physical devices. That way we may get improvements much faster than today and not needing 7+ months to support resolutions. Different idea's and ways of achieving outcomes will aid the adoption of the hardware.
please open source the driver so we can just fix this ourselves
The limitation of being boxed into 1920x1080 has driven me to remove DisplayLink and simply purchase a larger newer monitor such that I can get the required real estate space on an M1 with a direct connection. While DisplayLink seems to be capable of driving multiple monitors the lack of ability to change resolutions and retain readable fonts that are not blurry simply exclude it from being used in an environment where you are in front of the monitor for 8-10hrs a day. If this request had of been delivered upon then I would have retained my DisplayLink adapters and avoided the expense of a new monitor. Given the period of time this request has been outstanding I don't see the capability being available any time soon. The only alternative is to remove DisplayLink and replace by other mechanisms.
I face the same issue than you.
Here is my setup:
I connect my M1 MBP to a
- a first LG 27UL850 via usb C -> works well at 1440p for example
- a second LG 27UL850 via a startech display port dual 4K 60Hz adaptater -> same issue. Only 1080p or tiny 4K resolution available.
But I was wondering: has anyone tried to use an adaptater display port -> USB-C or display port -> HDMI between the startech output and the screen input ?
Besides, @tom said earlier : it seems that the M1 can't perform sub integer scaling.
But isn't it exactly what it does for my first screen which is directly connected to my Mac ?
Thank you for your insight on that matter.
I am using an M1 MacBook Air with an Asus PA32UC 4K monitor. With DisplayLink Manager 1.4 this issue is still not resolved. I can only select 1080p in the MacOS Big Sur Display settings, even when option-clicking on the scaling option. Using a separate tool I can access higher resolutions but only 4K fills my screen. If I select my preferred resolution of 2560x1800 then I have large black bars around the visible screen area and no option to scale.
I am using an M1 mac mini. The 4k monitor which is connected by using DisplayLink(Dell D6000) can display just FHD*1080p) retina mode with ver. 1.4 software. I cannot find 4k(3840*2160) resolution option. How can I solve this problem?? Is there any possibility to make HiDPI(2560*1440) resolution on the M1 mac with the Displaylink?
i need it to!!!!! cant only select 1080p or 4k. 4k ist to small, 1080p at 27inch is to big... 2560 x 1440 as HIDPI is the best solution!

Please add HiDPI support "Looks like 2560x1440" for 4k Displays. I don't understand why you are not adding this. Its the most common resolution you run on a 4k Monitor. Without this display link is useless on 4K.
Confirmed that 1.4 does not fix this.
Support said the following: "Fix should be included in the next release of the driver which will happen very soon I do not have the exact release date available yet though." (before 1.4 release) - so unclear what is going on there.
Right now with an M1 I'm using DisplayLink to power one monitor (not 4K) at full resolution and connecting the 4K screen directly which lets mac OS do the scaling... not ideal but it works.
Sadly no inclusion in release 1.4 either. It looks like that Displaylink and M1 simply can not perform sub-integer scaling ;(. 6 months and multiple releases and still no HiDPI on the resolution above 1920x1080. Guess usability for end users is not a priority.
Given the lack of ability to produce a scaled resolution with HiDPI at 2560x1440, and no response to the feedback, i've sent back my D6000 dock as well as the M1. There is no response that the current issue will ever be resolved so no point hanging onto the Displaylink dock. Seems that 4k monitors and displaylink with M1 MAC are incompatible unless you want really large text. Oh well was a good experiment just not useful.
Would be great if the PM could share more on why this is broken and what's the hold-up. It's clearly not working for a lot of people, so can be easily reproduced with off-the-shelf equipment. It's quite frustrating and not a good way to interact with your customer base.
I just downloaded version 1.3.1 (Build 56.126) and read the release notes quote "Re-added 4k mode on Apple M1 Macs missing after macOS 11.3 update (32869)". This feature is not working for my M1 MacBook Pro and I'm very disappointed in the company's SDLC. It took 3 months to release this new build and it's very clear there was no QA testing involved in the process.
