Anyone picking up the new Dell U4025QW (40" 5k/2k widescreen)?

[serrano]

Quick update.
So far, so good on my Dell U4025QW monitor. Again, using one of the 2019 style Mac Pros on my end.

I upgraded OSX to 14.4.1 without any problems....although I did do the update overnight and in the morning the screen was weird acting, I did a reboot and all was fine.

Anyone yet able to get 120hz refresh rate on a Mac?

Thank you in advance,

S

Anyone yet able to get 120hz refresh rate on a Mac?

setzer in the UltraWideMasters subreddit has researched and posted an excellent solution using BetterDisplay to set up 100Hz or 110Hz. His testing at 120Hz was unsuccessful/

I was stuck at the 60Hz limit on an M1 Ultra (regardless of DisplayPort, DaisyChained Display Port, USB-C to DisplayPort high quality cable, Thunderbolt 4) on 12.7.3. Now the U4025QW is working perfectly for me at 110Hz over DisplayPort on M1 Ultra. Should work properly on Pro/Max versions as well. Give it a shot. All the comments at reddit are positive.

If the thread disappears for any reason, let me know. I have all the primary materials saved locally and could repost them to MacRumors.

PS. Thanks to Mac owners' advice here and on Reddit, I've not upgraded the firmware from M3T101 to M3T102, nor installed any of the Dell add-on software. The built-in Apple colour profile seems to match the calibration of the monitor well. Even uncalibrated sRGB seems to be good enough for photo work (checking against past body of calibrated photos I know well). Eventually I'll custom calibrate my own U4025QW but for those who don't have calibration tools, calibration software and don't want to go down that rabbit hole just yet, out of the box looks good enough for even semi-pro work (sRGB only).

That's very cool. But it's pretty annoying that MacOS makes us do this hackie crap to get non-Apple monitors working. I had to do different (but similar) stuff to get HDR to work on my Dell 6K. At least that's sort of fixed in the latest Sonoma - but only sort of.

Got mine yesterday. Using Mac Studio with M1 Max I am unable to get 120Hz via Tb to DP cable, or TB4 cable. Tried native 5K2K resolution and scaled and can only choose 60Hz as max

I think there is an option on the monitor menu that you have to deactivate in order to squeeze the refresh rate. Does the text looks sharp enough? Any problem with scalation?

Ok, finally got mine (have been waiting for it for 2 months in Europe). The first surprise that it seem to get 120Hz (and even variable 48-120Hz) on MacBook Pro 16 2019. I did not believe it first, but different switches back and forth and tests do show that it is indeed 120Hz (got an MBP16M1 from work to compare - refresh rates looks similar on the monitor connected to the MBP2019 and the standalone MBPM1).. So does Radeon 5500M work better with refresh rates than M1 & M2? I got Sonoma 14.4.1 and now I am afraid to upgrade, since things seem to work nice out of the box. 😃

 

[Arise2B]

Btw, I have noticed that the top left and top right corners have a pattern of 3-4 dots / sort of markings of the assembly on the glass frame outside of the screen. Since the markings are very similar from the left and from the right I assume it is normal, or is it only on my specimen?

 

[serrano]

Yes on 14.4.1 no issues just make sure you don't update the monitor FW.

Just checking....

Have you by chance updated OSX to the latest 14.5 yet?

I figured I'd see if anyone had tested the waters with a new update that had this monitor...

I love mine so far...but, am hesitant to do updates hoping not to bork it.....

I have updated to 14.5 and did not notice any differences, all works fine for me (I did not bother with firmware update at all though - it says Firmware: M3T101 - I have no clue if this is new or old). So in short it works and can render 120Hz on 2019 MBP (but that leads to excessive fan noise which is annoying, so I am sticking to 60Hz until I get a better laptop).

Thats the original. I’m still on that fw I’d love to know if anyone is on the newer one released in march without issues.

 

[Arise2B]

What's the reason to update the FW then? Any issues with the original one?

so guys, received today after 1 month and half my 4025. I did EDID mods to enable 110Hz on MBP1 M1Pro, works well but I had an strange issue:

After wake up from sleep, monitor was back to medium resolution, became secondary (was primary before the sleep) and lost 110Hz mode. I had to reconfigure all stuff and reload EDID to get back faster refresh rate.

Anyone had same problem? Because it's an fresh monitor (build one week ago), firmware is already M3T102

Thanks in advance

EDIT: looks like that BetterDisplay should be always opened and option to auto-load EDID each time, otherwise it losts settings :\

I was thinking that EDID was permanet written on the monitor

Is the physical height of the display area of this monitor comparable to a 27 inch or a 32 inch 16:9 monitor?

Good question. This monitor is effectively a wider version of 4K 31/32 inch monitor. Screen height is exactly the same, PPI is exactly the same, just wider.

If you like running a 4K 31 inch monitor at 2560 x 1440 you will get a 3250 x 1440 monitor. If you like running a 4K 31 inch monitor at 1920 x 1080 (a little big but native retina 2x), you will get a 2560 x 1080 monitor.

What I do with mine is switch resolutions often (using BetterDisplay which manages switching and refresh rate much better) depending on whether I'm reading, writing or working in DxO PhotoLab or DaVinci Resolve (choose your own media applications).

Where this format (just as 4K 31 inch) lets one down is with PDF of A4 books. The height is a little bit small to be able to comfortably read books with small type.

Hello everyone
First, I would like to express my appreciation for the insights shared about MBPs with M chips. Let me summarise the key points in this thread:
1) Macbooks with M1 (even M1 Max) – 100-110hz available but only with this stuff https://www.reddit.com/r/ultrawidemasterrace/comments/1bciq31 2) Macbooks with M2/M3 (all of them or pro/max versions only?)—work well at 120hz without any extra configurations.
Is that right? I have an M1 Max MBP, so would it be better to upgrade to a new laptop with an M2/M3 CPU?

 

[lynxdeb]

That’s working well with M1 Pro, I’m using it on MBP M1P with BetterDisplay and work like a charm at 110Hz. I don’t think 10hz more worth that expensive upgrade

I’ll upgrade my M1 Pro when M4 Pro is out

Just got this screen yesterday, and it is an impressive display compared to the older U3824DW i'm using at work.

I've got a couple of rather annoying issues though, and it sounds like i'm not alone but i can't find any good solutions.

The main issue is the resolution, the U3824 got a max resolution of 3840 x 1600 which has been great with both my M1 and M3 Macbook Air.

Since U4025QW got a 5120x2160 resolution and I can only change the resolution down to 3072x1296, or 2560x1080 for some reason. Both of these produce way to large UI (or to small when using the screen for 8+hrs)

I can manually change to 3840x1620 but it is shown as "low resolution" and the text is blurry when used.


Has anyone found a good solution for this on the normal M3 CPU?

I'm also only getting 60hz, but I haven't tried the EDID hack yet.

You don't *think* that this is because of the issue described above?

Ok..
not trying to re-hash all the information that’s been brought up here on this, but should I want this monitor to work with picture by pictures (Dell laptop from work with 16” M1 MBP), is that possible? Or only possible at the 60 hz refresh rate? Based on what I’m reading in here, if I were to upgrade my MBP to the M2 or M3 then I could get both up tp 120 hz…is that correct?
