interesting, at one stage Phillips had a Europe-only 5K display, that used the same panel as Dell & HP. 2 DP and 3 HDMI in, looks like a good option - I skimmed the manual, couldn't tell if it's a dual cable for 5K.

It's a DP 1.4 display, so they might've skipped the dual-cable DP 1.2 support. Wouldn't buy it until someone confirms support.

Just curious, has DP 1.4 support in macOS already been verified/tested? I mean, Apple doesn't sell a single Mac with DP 1.3/1.4 outputs, so there's no need to support it...

I personally believe the LG 5K monitor is actually communicated via DP1.4 which embedded into Thunderbolt 3 (USB-C). Therefore, those new Mac can connect it at 5K Hz, but older Thunderbolt 2 Mac can only connect it at 4K 60Hz.

Even though there is no prove, but I believe the chance is there.

CORRECTION: There is NO DP1.4 support in TB3. TB3 still using DP1.2 standard.

From their web site.....

"Apple - Mac All iiyama monitors are compatible with Apple-Macintosh computers."

I notice this statement as well, but it means almost nothing. Any Mac can connect to it and display something (even as worst as 640x480) can fit into that statement. Compatible can means "backward compatibility", not necessary means "fully functioning" as expected.

Agree. I had the Dell 5k which was supposed to work but it was far from plug and go.... I returned it for a nice Dell 4k and I'm much happier with it...

From my knowledge TB3 doesn't support DP1.3/1.4, they're sending two DP1.2 streams over a single cable to enable 5K.

thing that confuses me - USB3/C has DP 1.3 or 1.4 available within it, and TB3 has USB3 within it, but it doesn't carry USB3's higher spec DP signal?

Thunderbolt 3 uses a USB-C connector, but it does not use a USB-C controller so it does not support USB-C's Alternate Mode (which supports DP1.3) and therefore is limited to the DP1.2 support of the TB3 specification.

ahh right, so DP 1.3 is granted to USB by the type-c port. USB over type-c is different to USB over a TB3 type-c connector. *facepalm*

seems disingenuous for TB3 on type-C to be called a superset for type-C if it doesn't offer everything USB offers when using the same port.

That's the beauty of USB-C: One physical connector for a variety of protocols which are incompatible to each other. The only thing you can rely on when you see an USB-C connector is basic USB 2.0 support, everything else is optional.

Reviving this thread to check if anyone has tried the Iiama 5K monitor. It is listed at Amazon UK at £768, how good can it be for this price?
DisplayPort 1.4. This is what we have all been waiting for.
Shame its supposedly only an 8-bit panel however.

This should work out of the box with any cMP with an RX/Vega or 10xx series card.

But I would wait for at least one review before jumping on it... In general, I like the looks of the monitor with the all glass front, but how good is it?
