I’m losing my mind. Anyone on here run 2 Studio XDRs off a MacBook Pro M4 Pro at 120 Hertz? I have the Anker Thunderbolt 5 hub also.

According to others' tests, either:
one of them runs at 5k120 the other one just black.
Or,
both run at 5k60.
And these are direct connections. Adding TB5 dock in the mix probably introduce further limits.

But this was weeks ago, not sure if recent macOS updates changed this.

M4 Pro MacBook Pro can only run a 5k@120Hz by itself - attaching basically any other display will require the 5k to drop to 60Hz (I have a 27" 4k and ran into this on my M4 Pro). The M4 Pro Mac mini can run a 5k@120Hz + a 4k@60Hz because it doesn't have the built-in display to contend with. I believe that M5 Pro MacBook Pro addresses this weakness - if I'm reading its specs correctly, it can do 2x5k@120Hz.

Thank you, I think it's dumb to introduce a new monitor that requires a brand new laptop in order get the full benefits.
 
Unless anything has changed, you can't just apply the Apple tech specs for supported displays to all chip types when it comes to the XDR.

For example... M5 MacBook Pro can't support the two XDRs that the Apple Tech Specs suggest it should be able to, regardless of refresh rate on those.

For those who ran into this problem, did you keep the monitors, how do they differ than the original Studio Displays at 60hertz

I was certainly disappointed to discover how limited display support was on M4 Pro MBP, but it's not quite right to say that you need a brand new laptop to get all of the XDR's features - it works exactly as advertised when used by itself. I think they could be clearer in how and where they describe the limitations when connected to different Macs, though. The way the specs are written can be hard to wrap your head around.
Those are the differences between a regular Studio Display and the XDR, minus 120Hz.

Sorry, I haven't read this whole thread, and forgot your bad experience getting different bits of Apple to agree with each other about what is supported (or not).

that was my case 😀DD Bought 2 xdr came home connected it , and i found out i need to buy new macbook...... sad and expensive story.

I did buy the M5, but my work laptop is a M4 Pro. Trying to convince them to upgrade me; get the most out of the monitors.

I did a variation on this, but with one XDR and my existing BenQ 27" 4k: I gave my M4 Pro MBP (24GB/1TB) to my wife - replacing the 16GB/512MB M1 Air that she only uses, screen open, hooked up to a 4k at her desk - and bought the slightly used M4 Pro Mac mini 64GB/2TB that I lucked into.

Left to her own devices (literally), my wife would basically never upgrade - this is at least her third or fourth computer in a row that I've passed down to her when I upgraded. She was getting a little tight for storage, so this works well for both of us. To be fair, the lack of 120Hz on the XDR with both monitors connected to the MBP was a fairly minor issue - I just knew that, in the next couple years (a safe bet for the storage/RAM crunch), I was likely to wish that I had more than 24GB of RAM for something, and 2TB internal is a better fit for what I need than 1TB, but I got a deal on that M4 Pro MBP ($300 off retail) that made upgrading anything painfully expensive, so I lived with it for about 17 months.

Now that I have the XDR, I only need a laptop when we travel, so I'll just create another user on my "wife's" laptop for that. I was going to trade the MacBook Pro in, but the difference between the very competitive trade-in price for the MBP vs the Air wouldn't have bought nearly as nice a replacement, so I'll trade the Air in for a few hundred dollars instead.

For those that have the Nano Texture panel on the new Studio Display XDR, are there any improvements with it compared to the Nano Texture on the original Studio Display?
 
I'm loving these screens, but still having random crashes with a brand new Mac Studio - machine freezes and reboots.

Each time I send the error report to Apple and have fed it in to chatgpt a couple of times too, each time it comes out with the output below.

Anyone having similar issues or should I just log a tech case with Apple? I'm not near an Apple Store and I suspect with this sort of issue, all they would do is maybe replace things, but I suspect its a software issue.

Memory pressure was high, but because the panic is clearly in DCP/IOMFB/RTBuddy, I’d treat memory pressure as a possible contributing condition rather than the root cause.

Most likely practical causes:

  1. External display, cable, dock, or adapter issue
  2. macOS display driver/DCP bug
  3. Sleep/wake or display sleep transition problem
  4. High-refresh/HDR/variable refresh mode change problem
  5. Less likely: hardware fault in GPU/display controller or monitor path

did you try setting 120 Hz fixed refresh rate? Many people report it fixing the crashes for them. I have it set as fixed and never experienced a crash myself.

As an Apple user, you might be used to everything working reliably, but based on my experience over the past 10 years working with HiDPI displays (such as Dell UP2715K = 5K or Dell UP3218KA = 8K, and later with Apple Studio Displays = 5K), I can tell you that you can forget about everything always working smoothly during the handshaking process between the GPU and the monitor. Even if you use the best connection cables, the connection process is always on the edge, and there can always be a synchronization issue, causing the monitor to remain dark and requiring the Mac or PC to be restarted to reset the display connection between the GPU and the monitor and attempt a new sync.

I always have to smile when more and more users notice these situations and only very slowly realize that this is absolutely normal these days.

Yes, its been set to 120 Hz automatically for both screens - presumably as its supported with the Max chip.

I wonder if I should remove the daisy chain element and put them both direct to the Studio, I've not tried that.

As originally a M1 mini, now a M4 Pro mini user, with a pair of DIY 5K monitors (built from iMac Pro screen panels - one connected USB-C to DP, one connected HDMI to the M4 Pro mini), I can say since I started using the first in early 2023, I have never experienced any of the boot-up problems you describe.
The only glitch has been the one connected using HDMI, which is mounted in portrait mode, has occasionally only connected in 4K mode.
That could be rectified by using a USB-C cable, but since it's mainly used for viewing vertical format video, it's not really a problem, and a reboot cures it...

I guess that the Dell screens, which date from a pre-DSC era where dual DP cables are required to connect them, are more prone to instabilities - with video drivers that must be a decade old by now, but the Apple Studio Display shouldn't be unstable if its not connected as well as an older monitor.

I've never had any issues like this before to be honest with Apple or non-Apple monitors.
 
a kernel panic caused by connecting a display is not normal and has never been normal. Period. Please, don't normalize obviously bad practices when Apple isn’t in a hurry to fix bugs that have been around for quite some time.
Who is talking about a kernel panic? Only you!
