Only if it can do the full 40 Gbps. A 20 Gbps cable can only connect one 4K60 display (for a computer that doesn't have a GPU connected to Thunderbolt that supports DSC).

Thanks! I guess since the Maxonar cable (https://www.amazon.se/gp/product/B08HN22G8P/) works with a Mac driving the Studio Display at 5K I should assume it would work with Windows as well as any cable?

Update:
If I use the Intel graphics app and set the mode to mirror using the internal (1920x1080@120Hz) display and the Studio Display I can actually choose 5120x2880.
As far as I can it is actually showing 5120x2880 on the Studio Display, and of course the same image on the internal display, but horribly scaled.
However, I cannot seem to turn off the internal display, if I try any other mode the Studio Display goes blank, and is shown as "deactivated" in the Intel app.
Speakers and camera work as expected.
Update 2:
I couldn't get 5K back, the highest resolution available in the Intel app or in the display settings was 4K.
Turns out that to be able to see the 5K setting and be able to get it to stick the Studio Display must be connected through the CalDigit TS3+, not directly to the laptop Thunderbolt port, mirroring must be enabled and the resolution of the internal display must first be set to 1080p.
It has become very clear that I must accept that the time where I knew and understood everything about how my computer works is long, long gone.
Can I determine if Windows is actually transmitting 5K to the Studio Display? Obviously the 5K on the mirrored internal display is scaled. Text on the Studio Display doesn't look great either, but I cannot tell if it is 5K scaled to 4K, or just Windows being Windows.
The "list all modes" button in the "display adapter properties for display 2" includes "5120 by 2880, True Color (32 bit), 60 Hertz", which is highlighted. Can this be trusted?
I took a screenshot in Windows and opened it on a Mac, and see the same crappy text rendering I see on screen, so assuming screenshots are taken pre-scaling (which seems reasonable considering the image is 5120x2880?) I am guessing I am in fact seeing 5K. It just pretty much looks like 4K because, well, Windows.

Update 3:
The "advanced display settings" for the Studio Display list "desktop resolution" as 5120 x 2880, but "active signal resolution" as 3840 x 2160, so I guess my suspicion perhaps is well-founded?

You're not getting the dual tile 5K60 mode. If dual tile isn't working (even though you are able to connect two displays to the same Thunderbolt port with a Thunderbolt dock), then you'll have to complain to Intel. And in the meantime, you can try creating custom timings for 5K with lower refresh rates using the Intel control panel. Let us know how high you can get.
The "active signal resolution" I think is a proper indicator in Windows of the output signal (something that Apple doesn't report in macOS without using something like SwitchResX or AGDCDiagnose).
No. I think as with the 5120x2880 mode that you tried, the list of modes shows only the desktop resolution and not the active resolution (same as macOS).
Right. Same as in macOS. A screenshot uses the desktop resolution, not the active resolution. I can have a 16K x 16K scaled mode in macOS output to my 4K display. When I take a screenshot, it image file is 16K x 16K.
Per your original question though, you yourself pointed out that this laptop should not be able to do more than 4096x2304@60Hz based on HP and Intel's documentation.
[Edit] Missed Joevt's question about tile mode. The UHD 620 can do 3 displays at 4K each, so theoretically you can have the laptop screen as one display and have the 2 other displays as tiles going into the Thunderbolt controller. But, I see this laptop also has an HDMI port, which probably has one of the displays hardwired to it. Hard to say what the problem is with this, could be the drivers - you should update the display drivers and the thunderbolt driver, could be BIOS settings, could be how the thunderbolt controller is wired to the iGPU. You should call HP support, ask them if it works with either an LG Ultrafine 5K or an Apple Studio Display. If you just mention the Apple display, they'll roundfile it but the LG has been around for a while and someone must have tried to use it with an HP laptop at some point.

But @Arctic Moose said he could connect two displays to CalDigit TS3+ #123 (one to DisplayPort and one to Thunderbolt port) without an MST hub which means the Thunderbolt port can connect tiled Thunderbolt displays like the LG UltraFine 5K or tiled non-Thunderbolt displays like the Dell UP2715K.
Built-in display + HDMI + two for Thunderbolt = 4 displays which is one too many. Maybe the connection used for HDMI is using a DisplayPort switch? That doesn't seem likely if it's using DP++ directly from the Intel GPU (limited to HDMI 1.4) instead of a DisplayPort to HDMI 2.0 adapter.
I hope it's not doing something weird like using a built-in MST hub. The old Intel Graphics Control Panel (not the newer Graphics Command Center) has a DisplayPort Topology menu that lets you see MST hubs.
I have no idea what laptop the User Guide for the HP EliteBook x360 1030 G4 is written for... It might have a built-in MST hub limiting output resolution to 2560x1600 which would mean it can't do 2560x2880 tiles.
I would redo the TS3+ dual display test: In the advanced display settings, it needs to say active resolution (not desktop resolution) is 3840x2160 60Hz RGB 8bpc for both displays connected to the TS3+.
The UHD 620 driver is 30.0.100.9864. I do not have admin permissions, so I cannot update it to 30.0.101.1660 which appears to be the current stable revision.
The Thunderbolt controller 15EB driver is 1.41.1193.0 which is the latest version as far as I can tell.
Of course the BIOS settings are also password-protected.
I'll try that, although I am expecting they will refer me to corporate support, where I do not expect to receive any sympathy for my will to use my own display at a higher resolution than that which the corporate-issued 1080p displays are capable of.
I did, and it does, except the frequency is stated as 59.939 Hz for the Studio Display and 59.937 Hz for the Z27.

Happy to report I get 5K60 and nice sounding ASD speakers from my 2080 TI's USB-C port using a proper 40 Gbps USB-C cable.
Hoping @joevt or anyone else can advise why I'm getting constant flickering on my Studio Display with the following Windows PC. (Note - the Studio Display works perfect with my Windows Framework laptop @5K and all supported Macs. Just this one PC giving me issues...)
PC: Windows 11, AMD Ryzen 3 5300G APU (integrated graphics) with ASRock X570 Phantom Gaming-ITX/TB3 motherboard. I'm using the Club 3D CAC-1331 HDMI to DisplayPort active adapter to "inject" DisplayPort into the motherboard's TB3 output. I'm using a Cable Matters 8K DP cable in conjunction with the adapter. Other DP cables behave the same.
This exact PC/config works perfect with my Pro Display XDR @ 4K60 and to my LG 4K display connected via USB-C.
When connected via a Cable Matters TB4 1m cable (and all others), the Studio Display has horrible flickering, but I'm able to confirm it's displaying 3840 x 2160 via the PC.Lower resolutions exhibit the same flickering. See comments further down.
I've updated to the latest AMD display drivers. And now I'm just out of ideas.

It might be a grounding issue, try your PC on a different outlet, do a cold boot, and also restart your ASD (unplug and replug)Hoping @joevt or anyone else can advise why I'm getting constant flickering on my Studio Display with the following Windows PC.

Funny you mention that.. I actually received a new/different power supply for the PC today and it exhibited the same display issues as the old one, and I used on a different breaker. So not a grounding or power supply issue.
However... I can report that booting into BIOS (which is probably 480x640 resolution?) on the PC results in a stable image! It's just when it loads Windows (even the login screen), the flickering starts.
I've updated the board BIOS/UEFI, and tried every possible config in the BIOS of "Special Display Features" and "Primary Video Adapter" all with no change. I wouldn't have expected these settings to make a difference, as they're primarily for integrated graphics vs. PCIe GPUs.
Normally, I'd chalk this up to 'oh well it just doesn't work'. But considering the image is perfect for the BIOS screen and with the Pro Display XDR, there is just something weird with Windows and the Studio Display.

Mine goes wonky when I have gsync on, disable variable refresh rate and set color to 8bp
I'm using the APU (FreeSync grayed out in AMD Graphics control panel), not dedicated graphics.
I was able to capture this, between insane flickers! I'm not able to change the refresh rate setting, 60Hz is my only available option.

Anyone else experience erratic sound distortion issues in Windows 10? I get on both Youtube music videos and elsewhere. Just spotted it. I've double checked all my sound settings and rebooted, nothing helps. I get noise distortion once every 30 secs to 2 minutes and it lasts for around 3-5 seconds.
UPDATE: Uninstalling the RealTek 5,1 Bootcamp drivers sorted the issue, sound is perfectly fine now. Just FYI this is on my Mac Pro 5,1 in Windows 10 with USB-C from RTX 2080 TI to ASD. Thought maybe this would help someone.
Everything is working superbly now, I get sound and brightness control on the Magic Keyboard even.
Edit: Nope, I still get distortion
Edit 2: Switching to my Mac Mini M1 and sound is perfect so nothing is wrong with the display itself.

One thing I’m curious about that maybe @Amethyst1 or @joevt know the answer to. From what I can see on the monitor EDID, this monitor is a dual tile DP 1.2 display, not a single tile 1.4 DSC display. Its very hard to figure out from Windows what the actual display timings are so I might be doing it wrong. Was this conclusively determined somewhere?
I've had sound distortion just once, I had to restart the ASD and the computer and it resolved it, have you tried using another tb cable?UPDATE: Uninstalling the RealTek 5,1 Bootcamp drivers sorted the issue, sound is perfectly fine now.

Yeah I have another one on order from Amazon which I'll get next week, unfortunately they are difficult to find locally.
It's only audio though which I find odd, you'd think there would be video issues as well but 5K60 doesn't skip a beat at 8, 10 or even 12 bit colour. It's not a huge issue, sometimes the distortions are ten minutes apart.
It's both. Use a Mac to get the full EDID. There's an EDID for the left tile and another one for the right tile. The last extension block of the left tile EDID has the single tile mode:
Code:
Block 3, DisplayID Extension Block:
Version: 1.2
Extension Count: 0
Video Timing Modes Type 1 - Detailed Timings Data Block:
DTD: 5120x2880 60.000000 Hz 16:9 180.000 kHz 936.000000 MHz (aspect 16:9, no 3D stereo, preferred)
Hfront 8 Hsync 32 Hback 40 Hpol P
Vfront 106 Vsync 8 Vback 6 Vpol N
Checksum: 0x95
Checksum: 0x90Is that different that the Pro Display XDR? I still can't figure out why behavior on my Studio Display vs. XDR is different.
XDR is similar. It's a DisplayPort 1.4 display limited to HBR2 link rate except it supports a tiled mode using dual link SST HBR3 over Thunderbolt which probably doesn't work in Windows or Linux.
The Studio Display's tiled mode is dual link SST HBR2 over Thunderbolt so it should work in Windows and Linux except maybe it doesn't. I'm not sure anyone's got the tiled mode to work in Windows/Linux - to prove it's the tiled mode, the display needs to be connected with Thunderbolt, the GPU needs to not support DSC (because we don't have a way to tell that its not using DSC unless we can examine DPCD registers), and it needs to use a HBR2 link rate and report 5K 60Hz RGB (8bpc or 10bpc, not 6bpc).
Wondering if I can help figure this out (I have a lot of things ha). Specifically, my Thunderbolt-connected non-DSC GPU doesn't work in 4K/5K (as referenced above).
