It's running full rez at 50Hz.
Refresh Rate (Calculated) 50 Hz
Window (Active) 3840 x 2560
Pixel Clock 544960000 Hz
Pixel Encoding 2 (YCbCr444)
Bits Per Color Component 2 (8 bpc)
Colorimetry 128 (BT.709)
Dynamic Range 1 (SDR)
The display supports 4:2:2 and 4:2:0 but I don't know if it supports those for arbitrary timings. The CTA-861 data block allows for defining known VICs as 4:2:0 capable but there's no VIC for 3840x2560. I guess 4:2:2 is expected to work with all VICs but, again, 3840x2560 is not a VIC. Maybe 4:2:2 is expected to work with any mode but macOS doesn't have a way to select 4:2:2 - you'll have to see if it tries 4:2:2 if you make a 3840x2560 60Hz timing. For 4:2:2 testing, probably Windows is better for that since the AMD and Nvidia control panels let you choose. Nvidia drivers in Linux may also let you choose (but not the open source Nvidia driver?).
The "log show" command might show if macOS attempts to add a 4:2:2 or 4:2:0 timing but you need to add filters to get it to show what you want.
Interestingly, the HDMI EDID doesn’t have the 2560×1440 60Hz or 3840×2560 30Hz modes the DisplayPort one has, but adds 3600×2400 30Hz.

There you go - two external 4K60 monitors (confirmed by their OSD) on the iMac
@eyoungren - I'm gaining on you
Actually, that is six monitors. One of them is so high-rez (5120×2880) that it requires two separate connections from the graphics card, with each driving one half (2560×2880) of the monitor. macOS combines the halves so they appear as a single monitor.Strange that you couldn't connect the Dell directly to the iMac even though it can handle two 4K60 displays. Were you using one DisplayPort connection per Thunderbolt 2 port? I used to have a 2015 MacBook Pro that could connect the Dell but that had a discrete AMD for external displays.There you go - two external 4K60 monitors (confirmed by their OSD) on the iMac
@eyoungren - I'm gaining on you
Yes. Maybe the physical height of 2880 pixels is a problem? I just connected the MateView to the Iris and it came up at 6720×3780 (scaled) at 30 Hz. 3840×2560 wasn't listed at all in RetinaDisplayMenu or the Displays preference pane - the highest 3:2 resolution available was 3000×2000, at 60 Hz. However's
AGDCDiagnose's output contained this - so does this mean it was physically running 3840×2560 at 30 Hz? (The monitor's OSD doesn't list the current mode, argh...)
Code:
HW State @ 0 DICT 5
Source Window 3840 x 2560
Destination Window 3840 x 2560
Scaling Taps 1 x 1
Line Buffer Depth 4 - 30 bpp
Interlaced No
SW State @ 0 DICT 5
Source Window 3840 x 2560
Destination Window 3840 x 2560
Scaling Taps 1 x 1
Line Buffer Depth 4 - 30 bpp
Interlaced No
I stopped at six.@eyoungren - I'm gaining on you

There was a brief moment where I actually considered eight and would have added another video card. But even I have a limit.
PS. I am not the only one who went after six displays.
Adam Savage of Mythbusters recently toured Grant Imahara's workshop. Grant designed it with filming a TV show in mind and set up a PC with six displays. At first he thought it was ridiculous but then discovered it was useful to his workflow.
I use three (four if you count that dual-cable monster as two). That suits me fine, and I think I'd be hard-pressed to come up with a use for another for the stuff I do right now. On the other hand, there was a time when I tried two monitors and couldn't make sense of it so...
Your previous AGDCDiagnose outputs did not include any Intel GPU detail so I don't know what you're looking at there without the rest of the file.
You need 631.75 MHz for 3840x2560@60Hz mode. That should be doable with DisplayPort 1.2, but maybe the Iris has a limit on max pixel clock? I would use SwitchResX to add 3840x2560 modes between 30Hz and 60Hz and see which ones work.
My wife used to think two monitors were ridiculous and that I was just being extreme. Then she went back to school for her teacher's degree and school is different now. She had to get up to speed with computers and the internet and on and on.
When the light turned on for her it was an "Ah!" moment and she now gets why multiple displays work. Of course, she does most of her 'computer' stuff on her phone, but that's another story.
Sorry. I've attached the full output with the MateView hooked up to the Iris.
We've seen that 605 MHz works on the iMac's internal display. But 594 MHz does not work on an external display.

I'm not sure what the LineBuffers info signifies. I suppose you could see what differs when you disconnect the MateView. I'm pretty sure it's only AMD info. Maybe it could be stuff on the MateView (connected with Intel GPU) that is accelerated by the AMD?
Doesn't look like it. I would look at the timing info shown by SwitchResX (when you double click the current resolution to see the pixel clock, active pixels, scale pixels, and other info).
Reliving the glory days of my misspent university years with a 512 MB 1st gen iPod shuffle hooked up to my trusty MacBook 5,2 (got it from someone for only $10!). I still remember when they were the hottest thing around. And I still regret giving the one I originally had to a girl who spent the night at my place when I was in grad school.
Sigh.
Sigh.
Just did:
- MateView is running at 3840×2160@30Hz via Iris Pro 6200.
- All scaled resolutions use that mode as base.
- Maximum pixel clock is 540 MHz.
- 3840×2560@30Hz isn't available even though it's within the pixel clock limit.
- EDID (exported via SwitchResX) contains all modes.
Also did some more testing and hooked up the IBM Bertha to the Iris via a Delock 62603. Bam, 3840×2400 at 12.7 Hz, so a height of 2400 pixels is fine. Decoded default single-link EDID (
AGDCDiagnose => EDIDUtil.sh) attached.(I can go through all the EDIDs on the weekend and send them your way if you're interested in them.)

One can do this on an early intel Mac.
great results!One can do this on an early intel Mac.
was this from a patch, than an upgrade?
this is a huge feather in your cap, bravo!
Tuesday, I received two 2006 Mac Minis and one 2009 Mac Mini from @chipchen. Included were also two Airport Extremes. The entire lot had all the power supplies. This is the first real opportunity I've had to look at them thoroughly.
The 2009 Mini is 2.26Ghz, whereas my current 2009 Mini is 2.0Ghz. However, the new Mini has only 4GB of ram while the old Mini has 8GB (I upgraded it last year).
I'm going to swap the two.
I also thought, since I'm going to have them both open. I should also upgrade the HD on the old Mini. I have that 500GB Sillicon Power SSD hanging around. It was in my MP before I got the 1TB Zheino. And, going by my rule of always upgrading either the same capacity or better this means the old Mini goes from 320GB to 500GB.
Using the Mac Pro and Carbon Copy Cloner to clone this morning's Mini backup directly from the NAS to the SSD.
Bonus: the new Mini has undamaged BT antennas.

Well…not exactly sure what's going on with the drive. It won't boot. Get's stuck at opendirectory "too many corpses". Tried a solution, didn't work, so now I'm just moving the Mac on to Catalina.
Not stressed. This Mac is non-critical and has sat off for the past several months so no biggie. And it gets updated to Catalina.
Found this inside though…
60GB SATA 3 SSD. Was not expecting that.

Possibly a long shot, but might this be a situation of the Mac mini having a SATA I bus (as memory serves, didn’t Apple move everything to SATA III at around the same time they moved to iX-series CPUs?) and an SSD whose controller doesn’t auto-detect a pre-SATA-III bus and set its speed to that slower/earlier protocol?
No, good thought, but the drive was actually booting. It just got stuck at a certain point. And Recovery sees the drive just fine.
Personally, I think it's a combination of factors. The original was an actual HD (still present in the old Mini). The new drive is an SSD. Because the original is an HD I did not partition as APFS. The reason for that is that the OS is installed using dosdude's Mojave hack. I no longer have that on my USB stick, otherwise I'd have tried a 'Post Install' operation. So, I just decided to move to Catalina (again, dosdude hack).
Not really a big issue, I had already moved my 2008 MBP to Catalina which is why I had it on my USB stick. But for these hacks to work with APFS formatted drives there's some code wizardry going on before the actual main boot.
I think a combination of all this is probably what caused the issue. Installing Catalina should fix it.
Again, not a critical Mac and was kind of fun learning a few things tonight.
Tip: You have to unmount your drive in Recovery if you want to convert to APFS. Otherwise it's greyed out.

Success…
2.26Ghz, Late 2009 Mac Mini 3,1. 8GB ram, 500GB SSD
Of course, this brings some app updating, but I've already been through that on my MBP. Tomorrow…

M.b. it's woth to look in direction to OpenCore?
It's manual promises bunch of miracles for Mac Pros .Say hello to 2011
2011 Macs gained SATA III along with Sandy Bridge.
