hello! i'm using the experimental scaling at 2560 but it works only in lodpi despite i'm being using the latest version.

My setup: macbook m1 13" 2020, dell d6000, samsung qn90b 43" and a 14" monitor fhd

Can you please fix the hidpi at higher resolution?

I tried the displaylink version 1.8.1 with adding new feature about scaling 2560x/3008x but this only temporary solution, the text is still blurring

Still no support for 1440p for 4k displays in 2023? I hope DisplayLink fixes this soon, since Apple continuously ignoring customer demands on this issue.
Apple being Apple - forcing consumers to buy their own overpriced monitors by tweaking their software not to support scaling for 3rd party 4k monitors, which come at a fraction of the price of their own monitors. And I will not buy it. BetterDummy is now known as BetterDisplay (if you buy paid version) will fix this issue BUT will mess up the virtual desktop feature, which is the only feature that keeps me with mac. As soon as Windows introduces similar independent virtual desktops, I am gone from the $hitty apple ecosystem. Tired of their monopoly by not allowing 3rd party integration. My 6-year-old windows connect with my two 4k monitors seamlessly (1440p), yet my brand new Mac doesn't.

How can I get two external monitors to be hi-res vs. one at 3008dpi and one at 1920dpi? I have a 2021 MCB w/ M1 chip

Is support for resolution 2304 x 1296 being planned ?

Version 1.8 Alpha allows me to select the correct resolution (great improvement!), but it still looks soft. It isn't as blurry as the low-resolution version, but about as blurry as a fake display created with BetterDisplay. A natively connected display at the same 1.5x scale (2560p on my 4k monitor) or the lower 2x (1080p) DisplayLink resolution are much sharper. From what I can tell, it looks like the new high-DPI resolution is not super-sampled, but rendered at native 4k.

I tried the missing scaling modes on my ASUS TUF Gaming VG289Q1A 4K monitor, but the resolution was still on as crisp as it should be with my M1 Macbook Pro (if you used scaled mode with the HDMI port directly from the laptop). I could only use for a few mins before it gave me a headache. Seems like a step in the correct direction though and hoping for further improvement!

First off, this has been going on for way too long. My text is huge or tiny it is ridiculous. This works fine on my non m1 mac, although it took years for it to work. Not only is my display resolution terrible, but the connection itself unstable. I have to unplug and plug things back in constantly until I can get all of the monitors on. Which drops my VPN connections of course. Not happy at all this is just a huge waste of my time repeatedly. Now it has been years of the same stuff this is ridiculous. I am not a happy customer at all I have had way more problems then success with display link.

Happy birthday to the work commencing to provide 2560x1440 HiDPI support. Must be extremely complicated given the fact that it is taking so long to provide the capability. Maybe best to open source and get a community to support the code.

Yet a year later, now at v1.7.1, still no 2560x1440 retina HiDPI (4k). I do agree with other comments in this section: 1440 is a standard now. Native resolution looks tiny, and 1920x1080 HiDPI looks huge and prevents the purpose of getting 4k monitors to being with: getting more on the screen.

I have spent countless hours trying to make it work with other software such as RDM, BetterDisplay, etc... when really, it should be a feature. It's almost a bug for not being there by now.

We're not asking for HDR or for 8K @ 60Hz here; we're just looking for a simple resolution scale!

I have DisplayLink 1.6.1 and 1440p on a 4k screen is still only available as a non-retina low-res option. I can get a noticeably better image using BetterDisplay (formerly BetterDummy) + Mirroring, but it's still blurry. If I use BetterDisplay + Streaming, it's a bit sharper, but the display performance goes down and it's still not nearly as crisp as a native 1440p high-res option.

@Maciej Ratajczak I think the answer is that Displaylink can not do it. The last response here was the update that it would be in 1.5 Beta 2.

Ok, so it's two years now. I just got my Dell D6000 and can't use 4K res scaled to 2560 × 1440. Looks like I have to give it back to the store. This is insane.

This is critical, please fix the product

We just managed 9 months post when this was reported as started. I guess its a complete rewrite to take this long. Maybe it will see a birthday in another 3 months. I'd suggest that you open source the code and let the community take it on and simply stay with doing the hardware. I'm sure there are some talented people out there that could deliver changes faster.

Want to add my frustration here as well, I recently bought a full setup around my work mbp M1 Pro including two 4k monitors, only to find out HiDPI is supported either for the full 4k resolution or 1080p. I do get an option for scaled 2k/1440p resolution, but the text is so blurry it's absolutely useless. Since it's a work laptop, I'm not even allowed to use external software like BetterDummy. Now I'm sitting with a $3500 wfh setup stuck with this absolute shit resolution on my monitors.

This is so annoying, 2k is a standard now, fix your damn product

We are about to hit 6 months since the work to deliver the request started.....

Pediction is that scaled HiDPI is not coming to displaylink as its been more than half a year since this page said it would be provided next release. That was a couple of releases ago. Best answer on 2020 M1 is to use betterdummy as that largely solves the issue.

Version 1.6 is now available. And the resolutions 2560x1440" is not yet available" option available for 4K resolution. Do you have any predictions?
