The display comes with an external power supply which must be plugged into the wall. It isn’t supplied with power by the computer at all.

mini paired with Hauwei's new 4.5K 3:2 monitor = iMac killer?

Successfully connected Magic Mouse to the monitor (via bluetooth) - it works!
Also found some info about HDR at Apple.com - it turned out that none of MBAs support HDR via DP! As I understand, HDR is available only on the m1 MBA and only via HDMI (which is limited to 50hz if on full resolution according to the MateView user manual).
MBPs starting from 2018 models support HDR via both, however I still can't make HDR option appear in monitor settings on my intel MBP 15" 2018. I've tried both USB C and miniDP connections.

Looks like you are using MBP 16", do you have an HDR option with MateView?

I'm curiours as to who the manufacturer of the LCD panel is? It's not listed on panelook.com
If anyone could do the following I would be interested:
1. Dump the edid data to a file with this command:
ioreg -lw0 | grep "IODisplayEDID" | sed "/[^<]*</s///" | xxd -p -r > ioreg.edid
2. Decode it using this:
or just post the .edid on this forum

I don't have it in Displays settings when connected via USB-C. I don't have proper dock to be able to test it via DisplayPort. After checking some forums it looks like HDR is only supported via DisplayPort 1.4 and MateView have DisplayPort 1.2 so most probably it won't work. I don't know which version of DisplayPort is going with USB-C connector (is it possibile to check it?). Also I'm not able to check it via HDMI because my dock is only supporting HDMI 1.4, but according to Wikipedia it should be possible to achieve HDR on HDMI 2.0.
That sounds weird. So basically they put HDR in there without anyone being able to take advantage of it unless you have HDMi 2.0?
Are you sure tje display port on the MateView is 1.2?

Sounds weird to me as well...
Yeah, it is written here: https://consumer.huawei.com/en/monitors/mateview/specs/
Actually it looks like HDR should be achievable in DP 1.2 (https://superuser.com/a/1335410) but it depends on software.
I think all the knowledge about display protocols is somehow blurry and complicated, at least to me...

Hmmm.. looks like I won’t be able to take advantage of the HDR then. Because my Radeon RX580 doe the following:
The HDMI on the MateView does support HDR but then my RX580 does not output enough resolution through HDMI to drive the MateView at full native resolution…
🥸
- DisplayPort: 5120×2880@60Hz
- HDMI: 4096×2160@60Hz

That's not your RX580, that's HDMI 2.0 limitation
. I don't know why they decided to choose HDMI2.0/DP1.2 over HDMI2.1/DP1.4. Maybe it is related to US ban?I have an RX 460 and the MateView runs at full resolution via HDMI 2.0 but only at 50 Hz refresh rate out of the box, as expected. I haven’t tried custom modes to get past 50 Hz since I use DisplayPort and only tested HDMI to compare the EDIDs.
I can’t test HDR since I’m on Mojave and HDR requires Catalina (or newer).
Where would I find that info in the EDID? I dumped it from
AGDCDiagnose‘s output. Throwing the hex EDID into that website produces totally false info.

Mine works after putting the hex achieved by
ioreg -lw0 | grep "IODisplayEDID" | sed "/[^<]*</s///" | xxd -p -r | hexdump -ve '1/1 "%.2x "'
EISA ID: HWV
Product Code: 6E22
Manufacturer is Huawei: https://edid.tv/manufacturer/2444/
I get that too (I decoded the EDID using EDIDUtil.sh) but that’s the monitor’s manufacturer, not the actual panel’s. For instance, it lists Dell as manufacturer for my Dell monitor but Dell don’t make any panels.

Yes, sometimes the EDID doesn't tell you much. Probably the panel itself will turn up on AliExpress at some point, like the iMac panels. At a guess the actual manufacturer may be BOE who seem to be the rising star at the moment in pushing new display technology.
Also, I have access to edid-decode on Linux, so if anyone wants to attach their .edid I can see if it parses any differently there.

I wonder if Iiyama's monitor uses the same panel (I know it's listed as being 28.0" rather than 28.2" but maybe that's just a mistake or inaccuracy) - somehow I find it unlikely that two different 3840×2560 panels would turn up all of a sudden. Not that I'd disapprove

Indeed, so it’s a mistake. Thanks for pointing that out.
I compiled
edid-decode on macOS - hopefully results of passing it an extracted EDID don’t vary across OSes... Someone attached their EDID to post 230 if you want to give it a try.

Yep! And it is also proved by the pics of it - even visually on Liyama's page and at displayspecifications.com it looks just like a classic boring 16:9 4k monitor
It definitely is! If you missed it, couple of days ago I've posted a review of MateView where HDR is working normally on Hackintosh with Radeon RX 580 running Catalina. Moreover I had it working without any problem on my previous monitor which also had DP 1.2 (Benq EW3280U, HDR 400)
Yep. I was too eager to post it that I didn’t cross-check the aspect ratio with Iiyama‘s site - sorry…
Today I received an email from Huawei support concerning MateView's HDR issue on macOS. They say that they are aware of the problem and that it is caused by some compatibility problems between MateView and macOS but they are already working on a solution in future firmware updates. That's good news
