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!

Thanks @Alvan Rampon - I have submitted my feedback and screenshots of the same behaviour on v1.5 beta via the email address you provided.

It would be great if there was a synaptics-monitored forum thread or similar for beta feedback if it is being made publicly available so that common issues could be identified and shared back to the product teams?

@anonymous I agree. If it can not be done don't sit there and ignore your customers but tell them the straight answer. Or if displaylink don't have the resources to do this just opensource the driver.

I see no difference over v1.4. I was always able to access 2560 x 1440 and 3008 x 1692 via option-clicking "Scaled", but it is still the "low resolution" versions being offered under the 1.5 beta. All I want is HiDPI 1440p. If this is never going to be available I wish the product manager would state it now so that we can all move on.

It doesn't work - still no HiDPI resolution for 2560 x 1440 or 3008 x 1692 !

I updated to 1.5 and restarted but still only see three options under-scaled for my 4K LG monitor connected via Dell DisplayLink dock.

3840 x 2160
1920 X 1080
1600 X 900

When I option-click the scaled radio button I get many more options including 2560 x 1440. Most are listed as low-resolution. It works but looks kind fuzzy compared to my other monitors. I'll contact support as you suggested to see if this is expected behavior.

I uninstalled the 1.4 DisplayLink Manager App, installed this 1.5 Beta, and rebooted. I am still not seeing the additional resolutions in display preferences on my M1 MacBook Pro.
>> "Introducing additional inferred resolutions on 4K monitors: 2560x1440 and 3008x1692"

Did You read it ?

"C.4 Changes in 1.5.0 beta
----------------------------
- Introducing additional inferred resolutions on 4K monitors: 2560x1440 and 3008x1692
- Beta: Apple Watch unlock when resuming displays from sleep (33190)
- Fixed monitors power save mode issue on macOS Monterey 12 beta (33198)
- Improved memory management on rotated screen (33179)
- Improved rotated monitor performance on dual GPU machines (33072)"

+3 for this suggestion to make 4K monitors useful. It's otherwise wasteful to run them at 1080p, and far too small text running at their native resolution without scaling.
A 2560x1440 HiDPI mode is badly needed.
Thanks

Please add this Displaylink!!!

Would be great, please add 2560x1440 on 4k monitors.
