Right, I was focusing in pixels. Forgot, we are after Mac Display XDR Vibe rather than gross gaming kitsch one.
 
I live in Finland and ordered a Tcolor SC-MZT-L32660 monitor from Alibaba for €733 (the price included all costs) two weeks ago, and the package was delivered to my door yesterday. I have now used the monitor for one day with a MacBook Pro M1 and a Mac mini M4, and I haven’t noticed any major issues so far.
What is your verdict now that it’s been a week?

I’m satisfied with the purchase. I’ve now used the monitor for a week for work with a MacBook Pro M1 and for leisure with a Mac mini M4. The brightness has been sufficient and overall it has worked well.

Cons:
• Only 2 × USB-A (+ 1 × USB-B) hub ports
• High-pitched backlight whining at certain levels when using hardware dimming

Pros:
• The advertised specs seem to be accurate
• No dead pixels or similar issues
• Sufficient brightness
• High-quality and stylish build (aluminum)
• Brightness adjustment with software dimming works using free utilities, e.g. BetterDisplay and MonitorControl
• Sufficient charging power for a MacBook Pro

@pommac,

Looks good! How are the buttons and menu system? I see you have a Mac mini M4 and MBP M1. With both, do both 4:4:4 chroma (with 1:1 non-scaled resolutions) and HDR work?
 
Colors look good! The menu bar text with my old Kuycon G32P had a blue tint instead of the nice crisp white, but that was due to a blue hallow around the edges from having a bad panel.

I’m not able to answer the 4:4:4 chroma question. However, this monitor only has 400 nits of brightness, so HDR is not really usable. In practice it would require around 600–1000 nits to be worthwhile.
The buttons are located on the right side and feel like metal.
The OSD menu defaults to Chinese, but it is possible to switch it to English.

If you’re interested, you can test 4:4:4 by switching to the 1:1 resolution non-scaled (6016x3144) and then downloading the test page at this link:


Look at the test pattern at 100% without scaling and take a picture (not screengrab) to see if it is displayed correctly. If 4:4:4 isn’t working, the blue and red vertical lines will only display every second line.

Excellent. 4:4:4 working properly on a Thunderbolt 4 / DisplayPort 1.4 Mac. That means Display Stream Compression (DSC) is fully functional. 🙂

The Tcolor seems like an excellent option, and way, way cheaper than the Kuycon. I also much prefer the idea of the Tcolor's buttons over the Kuycon's remote.
 
Yeah this monitor looks excellent value. Sadly I live in the US so I suspect I would get choked to death with tariffs if I tried to order one.
 
What about the high-pitched whine? Could that be due to a defective unit?
Adjusting the screen brightness may cause a high-pitched whining noise at certain brightness levels, which, as far as I understand, is a known phenomenon with some monitors and is related to the backlight control (Pulse Width Modulation).
 
What about the high-pitched whine? Could that be due to a defective unit?
I (and ChatGPT) believe the backlight control uses Pulse Width Modulation (PWM), which means the screen does not actually lower the lamp or LED power continuously, but instead turns the backlight on and off very rapidly to simulate lower brightness.

With PWM, the brightness is controlled by changing the ratio of on-time to off-time (the duty cycle).
• At high brightness the light is on most of the time.
• At low brightness the light is off for longer periods and on only briefly.
Even though this switching happens hundreds or thousands of times per second, the human eye usually perceives it as steady light.

It can cause a high-pitched whining or buzzing sound because the rapid electrical switching can make coils, capacitors, or other components in the monitor vibrate slightly. These vibrations may fall into the audible frequency range, especially at lower brightness levels where the PWM duty cycle changes more aggressively.

The latest review on the Alibaba page includes a mention of buzzing sound ... might be the same issue @pommac is having:

"the power supply is external (24V 5A) and the one it came with was very noisy with an annoying buzzing sound, but you can just use another one"

From: https://www.alibaba.com/product-detail/Color-Accurate-6k-Monitors-32-Inch_1601525173783.html
In my case the noise is not coming from the external power supply. The sound is clearly coming from inside the monitor itself, and it only appears when I reduce the hardware brightness. At higher brightness levels the monitor is quiet. This suggests it is related to the backlight control (likely PWM or internal electronics), not the external 24V adapter.

Also, I noticed that the external power supply does not have a CE marking😱.
CE = Conformité Européenne or China Export🙂

Hmmm. I forgot you mentioned that whine in your review.

The lack of any CE or similar marking is disappointing but the whine may be this product’s true Achilles’ heel if widespread. M1 series Mac Studio anyone?
 
I’ve been hit with some duty surcharge above expected vat(uk). So it is going to come to £800. Making it quite questionable choice given dell can be had for £950 with 3y warranty hdr600 and connectivity.
My only defense can be envelope, vertical stacking capability and no diffusion. With the latter could be virtue or curse we’ll see

Did you run the noise issue by Tcoior?

With hardware dimming it can be hard to find a level without the whining sound, but if software dimming is enough, then it’s not really a problem.
