Think the response here is that this request will never be fulfilled either because of Apple issues or Displaylink issues. Close to a year after the request so looks like its never going to happen. Just waiting and hoping the m1x has 2 display support to remove the need for this 3rd party use.

Release notes from release version of 1.5:

"Introducing additional inferred resolutions on 4K monitors: 2560x1440 and 3008x1692 on Intel based Macs"

Looks like there continues to be issues with M1 and this product. Very disappointing.

Just waiting for potential new mac announcement this week. If that supports dual monitors natively then there will be a solution. Trade in time and change to where there is no dependency on a 3rd party.

+3, even the newset beta does not change anything (M1 MBP), I need to either use blown-out "retina" 1080p (@2x) or 1440p low-res, please guys – fix this as this issue kills your overall great product for me

@Yo Jan Hong all I can say is look at the date of the original request and todays date to gauge progress. There has been rumors of it being fixed in various updates from displaylink but nothing eventuated. There is a another rumour it may be fixed in macos12. More rumous and nothing official. You can not solve the fuzzyness with displaylink on a M1 unless your on 1920x1080p. This is what the current technology is capable of. Personally, I'm waiting for the M1X which is rumored announcement is 7th September and availability end of September to see if it supports dual monitors. If so I'll be trading a M1 in and getting rid of my dock.

@okv - I see. So my monitor default is 2560 x 1440p, but the scaled option via display link only gives me 3 options = 3840 x 2160 (low res), 1920 x 1080, and 1504 x 846...

I'm forced to use 1080p right now on 1440p monitor, and it works but it's fuzzy and looks blown up. I'm trying to even debate if I should return my dock with displaylink technology, accept the fate with one external display, and deal with it...

@Yo Han Hong it is supported but only at low res. If you have a 4k monitor it will mean the text is fuzzy.

Just getting started with Display link due to my M1 Mac not supporting multiple displays...

I'm not a tech savvy person here, but I just want to make sure that I understand this correctly. The 2560 x 1440 resolution is NOT supported right now. Is that correct?

Read a rumour article last night that new Macs are planned for September! I'll be the first to sign up to remove this issue of a single good display and a blurry display with displaylink. Hurry up apple and provide a fix with new hardware.

Please add HiDPI support for 1440p scaled!

Or at least a passthrough option for running one monitor using the built in scaling.

After a year I believe the best option is to remove the 3rd party dependency altogether if the opportunity arises. If Apple release M1X with native multiple external screen support I'm trading in the M1. Seems the only way to get a reliable outcome that does not takes years to achieve. M1 was never intended to do multiple external monitors and this is showing through on how long its taking to get HiDPI on 4k monitors with Displaylink Technology. Time to move on in a couple of months hopefully.

Response via tech enquires email, sounds like it’s still being worked on for M1 Macs - hope it gets there for final release!

“These new resolutions have been enabled for users that struggled to choose them.

The case with HiDPI modes is that choosing them on M1 macbooks differ to the Intel laptops.

Intel based Macbooks should be able to use these two resolutions in HiDPI modes. As for the M1 Macbooks we have enabled more resolutions and we are still working on making high res modes available.

I believe there is a testing case where it is already working on BETA Monterey but I cannot guarantee that yet as we are still testing it.”

waiting till the M1X to trade in the current M1 so I can move away from this technology. Seems to be the only answer for M1 Mac to get multi-screens is to wait for Apple to deliver it. Cross fingers M1X supports multiple displays then I can sell this dock.

Jeremy Bruns - The highest 4K resolution has been working for a very long time. This topic is about 2560x1440 and 3008x1692 (not fuzzy - HiDPI support) resolution ;)

Works for me in beta 1.5 holding the options key and choosing the highest resolution.
It says low resolution, but it actually displays in the correct resolution, not fuzzy at all!
<3 Thanks DL

This is my setup:

MacBook Pro M1
Big Sur 11.5.2
Icy Box IB-DK2244AC
Screens 2x AOC U32P2 (2x 3840x2160)

Yes I've installed 1.5 beta and still only seeing 3840x2160 (low res), 1920x1080 & 1600x900.
Please please add support for more useful scaling options 2560×1440 and 3008×1692!
Thanks!

I will not see any difference between the latest release. don't get what's actually update.

I don't see any difference between 1.4 and 1.5 beta. still same things there

Good news: The colour rendering / contrast issues are fixed when I choose the 1440p option!

Bad news: it's still low-res 1440p!
