Interesting review just came out yesterday. First I've seen from an English user in the UK. Seems clickclack now ship to the UK for $100.

Very interesting. For those with access to buy any of the 3, any particularly reason you'd choose this over rate Asus or Viewsonic 5K 27" options?
Richard.
It's glossy and has the brightest backlight (650-700 nits (measured) according to 2 reports I found) of all the current options.
Also, according to the video it seems they've silently upgraded their displays to offer both 75Hz and 60Hz (the same trick that Viewsonic use).

On the flip side, it apparently has obviously uneven backlighting. I have that on my Huawei and it’s irritating. I’ve gotten used to it but I’m really hoping the new crop of Retina 32” monitors this year don’t have that problem.
I wonder what % of users operate a display at over 500 nits?
When I used my old 2017 27" iMac, I think it was rated for 500 nits and I didn't run it near 100%. Most 27" displays I've checked into didn't go with 500, IIRC; more like 350-400 or so, give or take?
It's nice that this display can get to 650 - 700 nits; I'm just asking how many people will benefit from that capability.
Another question is whether running a display near its max. brightness is set to shorten its lifespan. If someone runs a 400 nit display at 100% and a 500 nit display at 80%, does the strain wear the former out faster? We know smartphone batteries tend to last longer if we usually charge to 80%, not 100%. It brightness analogous?
The location of the ports are very unfortunate. It sticks out for no reason. They shouldn've centered it and placed it near the bottom.
KTC H27P3 5K 27” is less than US$600 in China. That means with US tariffs it might be $1299.

The interesting part for me though was the refresh rate. 60 Hz at 5K and 120 Hz… at 2K. I’m sure the new crop of high ppi monitors will be similar, with no 120 Hz 5K or 6K.
This ultra-affordable 5K monitor is great for gaming and superb for creative and business but I can't stand its stand
KTC H27P3 offers dual modes, making it perfect for creatives and gamers alike

No idea. I am waiting for a 5K or 6K 31.5" monitor this summer.
There are now some chinese language reviews of the KTC on youtube. Seems to have the best backlight of all the BOE panel 5K monitors so far: 500 nits (real), 2048:1 contrast (real), 99% P3 (real). Might come to Amazon later this year. Think I'll wait for this one.
Note - they did mention the monitor is dimmer along the edges, but to be honest that wouldn't bother me. One of my iMacs has pink edges due to the optical adhesive ageing and I don't even notice it.
I tested out this cheap 5K monitor - and for the price, I have to wonder, what's the catch?
A 5K display for under €700 - the problem is, it's only available in Europe
Real contrast: 2090:1. Brightness: 411 nits. P3 100%.
That means text is going to look significantly blacker than on an ASD. I think BOE has a good panel here, providing the manufacturers pair it with a decent backlight.
It's strange that ASUS and BenQ didn't manage to get such good contrast in their models.
Display Week is currently taking place in San Jose. Experience has shown that new displays and new panels are also presented there. Do any of you have further information on what's new and interesting?
I am looking to upgrade my 2017 27" iMac to a Mac Mini Pro + 27" monitor solution. I'd like to keep with 5K, and not wanting to fork out for a ASD I've narrowed it down to the Asus ProArt PA27JCV or the BenQ PD2730S. I like the idea of the ports on the BenQ, so am leaning towards that. Has anyone got any "side by side" experience of both monitors please?
Finally more 5k & 6k Displays

And no news about the Asus 6K ?
From that link:
"A wide range of connectivity options
ProArt PA32QCV offers extensive connectivity options including 2x Thunderbolt 4 ports with 96W Power Delivery and daisy-chain support. Plus, there’s DisplayPort 1.4 (with Display Stream Compression), HDMI 2.1, and a USB hub to ensure seamless integration to any workflow. Built-in Auto KVM allows for effortless switching and control between two connected laptops or PCs via a single keyboard and mouse for easier multitasking. The monitor’s ergonomic stand provides users with tilt, swivel, pivot, and height adjustments for the ideal viewing position."Interesting. The latest version of DisplayPort is 2.1a; given that this is such an advanced display in resolution and a new (not even released yet) item, I'm surprised they went with DisplayPort 1.4. From this Cable Matters page:
"DisplayPort 1.4 is a digital display interface developed by the Video Electronics Standards Association (VESA). The DisplayPort 1.4 standard was first published in March 2016. While it didn't introduce any new transmission modes and did not increase the available bandwidth or data rate, it maintained the strong showing from DisplayPort 1.3. DisplayPort 1.4 has a maximum total bandwidth of 32.4Gbps and a maximum total data rate of 25.92Gbps. That gives it enough bandwidth to handle a 4K UHD stream at up to 120Hz with 24-bit/px color, or a 5K display at up to 60Hz, with 30-bit/px color. It even supports 8K video, but only at up to 30Hz due to the hefty bandwidth demands."
They have another page with this bit about HDMI 2.1:
"It has native support for 4K 120Hz gaming on consoles, at up to 4K 144Hz on gaming PCs with powerful enough graphics cards. It supports 5k resolution at up to 60Hz, too, as well as 8K at up to 30Hz. However, with DSC, HDMI 2.1 is capable of handling 8K at up to 120Hz, with HDR."
6K seems to be something of an 'odd duck' resolution that's not always mentioned when the capabilities of varied connection standards are discussed. The question that comes up with this 6K 60Hz (I presume 60Hz is the refresh rate; didn't see that to confirm) display is: of DP 1.4, HDMI 2.1 and Thunderbolt 4 connectivity options, which support 6K at 60Hz, and is DSC required to do so?
For DP1.4 I think it entails needing HBR3 + DSC to work?
In the context of Mac use, it is not like we need to worry, the DP-alt inside the TB4 connection will take care of that, as with the Apple XDR Pro Display that also needs DSC.
But yea for other inputs especially the HDMI2.1 that should be interesting. Let's say you want to spare the TB bandwidth on a Mac, then use the HDMI port, is 2.1 required or 2.0/2.1 with DSC is fine.

6K 60Hz uses a pixel clock of between 1273 MHz and 1290 MHz (CVT-RB2 and CVT-RB).
HBR3 x4 can do that using 4:2:2 10bpc or RGB 6bpc (usable on PCs). DSC is required for RGB 8bpc or greater.
Using Thunderbolt 3, the Apple Pro Display XDR can do 6K60 RGB 10bpc using a dual HBR3 x4 mode for Macs that don't support DSC. I don't think anyone but Apple can use this mode. DSC is preferable because 6K60 with DSC takes less bandwidth than 4K60 without DSC and you can connect two such displays to a Thunderbolt 3 dock.
HDMI 2.1 has more bandwidth than HBR3 x4 if you are using FRL4 or greater.
FRL2 can do 6K60 using 4:2:0 8bpc or DSC @12bpp.
FRL3 can do 6K60 using 4:2:2 8bpc or 4:2:0 10bpc or DSC@16bpp.
FRL4 can do 6K60 using 4:2:2 10bpc or 4:2:0 12bpc or DSC@20bpp.
FRL5 can do 6K60 using RGB 8bpc, 4:2:2 12bpc, 4:2:0 18bpc, DSC@24bpp.
FRL6 can do 6K60 using RGB 10bpc...
HDMI 2.0 doesn't have DSC but maybe HDMI 2.1 can use a HDMI 2.0 link rate with DSC. FRL1 and FRL2 are HDMI 2.1 link rates that work with HDMI 2.0 cables (3 lines instead of 4 at 3 Gbps or 6 Gbps each).
