HP's new 40" 5k/2k 21:9 Z40c G3 monitor announced at CES - should work great with M1 (and pro/max) Macs yes?

Any reason to think this wouldn't work great with an Air or MBP?

Except the specs for the Z40c with the higher resolution said 30Hz refresh.

Huh. That is indeed what the page I linked to says and would for sure be an issue. However, I haven't been able to find that specified in any of the HP press releases. Do you see it anywhere else? Seems....weird at the very least that they would do that.

Could be either a lower-grade panel that is designed for 30Hz or HP did not want to spring for the development of a custom timing controller to allow it to be run at 60Hz like Apple did for the iMac 5K family and LG did for the 34WK95U-W.

Curious about what each of you gleans from the spec sheet:

HP Z40c G3 WUHD Curved Display Datasheet.pdf

Shared with Dropbox

www.dropbox.com

In one place it says "Maximum Resolution (WUHD 5120 x 2160 @ 60Hz)" but in another place it says "Vertical Display Scan Frequency 29-71Hz" I guess implying that it does drop that low.

BTW if the dropbox link feels sketchy it's straight from HP. Go here:

Right, I see that and called it out. But what do you make of the 29-71Hz scan frequency. When/why would it drop lower than 60 if not at the highest resolution? Do people choose to do that for some reason? (Honest question)

Most, if not all, monitors offer a range of frequencies. My ASUS PG279Q can go as low as 30Hz and as high as 165Hz.

Got it thanks. I've had my iMac for 7+ years so haven't had to deal with external monitors in so long I sort of forgot!

Well, depending on what Apple announces this Spring I may get a 14" MBP and this HP monitor as my next rig...thanks.

It’s not 16:9, it’s 21:9.
No thanks!

 

[megastuff999]

If they can get one of these to me faster than Dell can get the 40” 5K2K I have on order (latest delivery date end of March) I’ll be getting one!

Yikes. Sorry about that!

140 PPI. I’m not sure if that is going to work well with macOS.

I have a 21:9 monitor: My Mac mini 2012 can only use the full resolution with 30Hz

The native refresh on the Z40c G3 is 60hz….I’ve messaged the writer at Windows Central for a correction. It’s the same glass panel as the Dell U4021QW and Lenovo’s P40w-20. The 60hz only requires DP 1.4 via the DP port or USB-C using DP 1.4 Alt mode. The M1 will have no issue running the full 5120x2160@60hz.

Cool thanks. Interested to see if any implementation differences bt HP, Dell, and Lenovo make one or the other the one to get.

Any buy ins?

 

[anthonymoody]

I ordered the LG version which is finally shipping. Ordered from LG directly as their return policy seems fair (14 days in original packaging). I'll see how it pairs to my 14" M1 Max....

Await the review..

Await the review..

Sorry I put some thoughts in another thread because it's where I found the info needed to get it to work correctly with my M1Max 14" MBP.

M1 MBP & LG 34 inch ultra wide 5K2K

What’s the best thunderbolt 3 dock for this monitor? I’m using an M1 Pro 16” 2021.

(the instructions for getting it to work are in a post on P25 in that thread)

My thoughts on the 40" LG:

Coming from a 5k iMac (the OG, late 2014 model) the text is definitely not as razor sharp, but I'd describe it as "very good" and definitely good enough for me to keep. The 3840x1620 72Hz HiDPI resolution (thanks SwitchResX) works really well and strikes a good balance between screen real estate and readability. Sound isn't as good as that on the 14" MBP funny enough, but fine. Laptop charges via the TB connection.

Not sure if I'll ever be able to go back to "normal" sized screen(s) after this. Even if Apple comes out with something like a 6 or 8k 32" consumer screen [ETA - which they did not, and I'm *really* glad I didn't wait for the 5k 27" studio display they just released as I wanted more real estate]...not sure I'd trade the LG for such an animal at this point. The only thing I'd appreciate and trade for would be even greater pixel density but at this same physical size...

One more thing to add - scrolling isn't quite as smooth as on the iMac despite being 72Hz (and confirmed in both SwitchResX and system report). Same with cursor movement via Magic Trackpad. It's "fine" and definitely not a deal breaker, but I notice it.

Checking the HP data the 60 hz refresh is available via Display Port or Thunderbolt/USB 3.0 connections but not via HDMI (which is limited to 30hz at max resolution). Should not be a problem for Mac users as the Thunderbolt connection would not only allow max resolution/refresh rate but would also enable the multiple ports/speakers/web camera/ethernet features using a single connection.
