MP All Models SOLVED: 8k Displays Running on Mac Pro? Any? What Video cards would work that support 8k HDMI 2.1/Displayport 1.4/2.0 displays on Mac Pro? YES you can

Why do you need 8K?
Click to expand...

I explained it early in the thread. But I need a LOT of screen real estate for my work. I currently have 6 30" cinema displays giving me about 24megapixels worth of desktop screen real estate. One 8k display provides me with about 33mega pixels of desktop screen real estate.

The above shows you that 1 8k display shows more than my 6 30" cinema displays (same horizontal resolution, but more vertical resolution).

So I will replace my top 3 30" cinema displays with this new 85" 8k display (but still keep the bottom 30" cinema displays). Physically the 85" 8k display is about the same width and physical footprint, side by side sitting on your desk, as the 3 30" cinema displays. So I'll end up with net around 45mega pixels worth of desktop screen real estate when I'm done.

Ultimately I want to replace this god awful setup, but I need sufficient screen real estate with sufficient scaling. 8K would give me that.

I ask again as the use case may have changed over time.

Is your use case revenue generating?

Do you really think he'd have 6 (!) Cinema Display's mounted together if it wasn't for some professional (e.g. revenue generating) purpose?

I've seen many gaming setups exceeding in that setup. So I'd like to know what the use case is.

Yes I use it for work. Actually, at one point I had the 6 cinema displays AND 4 65" 1080p TVs joined into a single 160" wall display for work. I may recreated something like that again soon.

But it's terrible in that once you use this, going to a system with less screen real estate becomes really unpalatable. A bit like moving from a spinning hard drive to an SSD, you really never want to go back.

From the picture is worth a thousand words department, this was my setup a while ago. I've modernized a lot of this, but gives you the feel. 6 30" displays and 4 65" displays all hooked up into a single desktop.

It shows a quick pan over the 6 screens, and then I had the 4 65" screens embedded into a wall as single display behind glass, so I can whiteboard over the glass. So 10 screens total.

@Pressure @ZombiePhysicist @joevt do any of you know if that still functions correctly w/ M1 Max/Pro?

I'm half tempted to put a bid in on https://www.ebay.com/itm/304347982286 and give it a go, if so. But my understanding so far is that everyone who has/is using the display like that is also running an Intel based Mac.

I only tried it with the Mac mini M1, which didn't work for obvious reasons.

I'm waiting for the new Mac mini with M1 Pro and M1 Max to upgrade.

I received the CableDeconn adapter and tried to replicate ZombiePhysicist’s success with 8K, but without full success.

I used a Mac Mini with AMD 6800XT, CableDeconn DisplayPort 1.4 to HDMI 2.1 adapter, connected to a Samsung Q800 8K TV, using the HDMI 4 input that supports hdmi v2.1.

I tried different displayport output on the 6800xt.

So very similar setup, using the same cable, but not sure about firmware version.

ZombiePhysicist said:

Ok, to get 8k to work on an HDMI based TV/monitor, I was successful with the following equipment:​


(1) 2019 Mac Pro (on macOS 12.1)
(2) AMD Radeon 6900XT (I think reference card) from Sonnet with ports: 1-USBc, 2-DisplayPort 1.4, 1-HDMI2.1: Plug it into DisplayPort port 2 (the DisplayPort port next to the USBc port). The 6900XT card is plugged into slot1 in the Mac Pro. I doubt it makes a difference, but I also have WX9100 plugged into slot 4, and highpoint U.2 7120 in slot 5.
(3) Samsung QN85QN900AFXZA 85" 8K TV with 4-HDMI2.1 ports: plugged into port 1 (and put the TV into Game Mode to reduce text-contrast-artifacts and remove dithering)
(4) Use this CableDeconn DisplayPort 1.4 to HDMI 2.1 cable (firmware version 6.03.146)

I added this custom resolution using SwitchResX:

(5) You need SwitchResX and need to set it to the following manual settings:

.. and it seams to create a bunch of non scaled resolutions incl 8k Under the current tab.
also weird things happen with the screen. I sometimes get scaled 8k, really a 4K image, two other times the TV turned green, and yet again other times the desktop turned upside down on the TV (180 degrees rotated), very weird indeed.

But I can’t activate any the these new resolutions. In the custom resolutions tab, suddenly the custom resolution shows 2090.06hz, but it can’t be activated.. or it will not stick.

ZombiePhysicist said:
Note that entering the above manual entry does something that makes this following "automatic" entry instantiate and is the actual setting I select under the current resolutions tab:

You may need to switch back and forth from one setting to the above active setting before the 8k "sticks":

Not sure actually what resolutions to switch between. All seams dead.

ZombiePhysicist said:
Caveat: Changing resolutions seems to get 'iffy'. So going back and for a few times can get it to 'stick'. For now, 30hz does not seem to work but 60hz does, but you know, meh, who cares!
Click to expand...

Nothing happens when I click these resolutions. I can’t even open them to see the details. SwitchResX shows a dialog box saying info not available.

In the SwitchResX menu bar menu, both millions and billions of colors show up, as well as a HDR options. Maybe I can’t get MacOS to turn into 4:2:0 chroma sub sampling (which seams to be required to get 8K).

SwitchResX when you click "Activate Immediately...", it does a rotate do get the modes enabled.
Instead of clicking "Activate Immediately...", you might have better luck disconnecting and reconnecting the adapter.
Post results from AllRez and AGDCDiagnose so we can see what's happening with the modes and get more info about the TV.

AGDCDiagnose for two attempts: The CableDeconn DP1.4 to HDMI 2.1 adapter is connected to the Samsung Q800 8K TV. I start out with a HiDPI 1920x1080 resolution (4K), and try to change to 8k with pix clock 2090.06Mhz as ZombiePhysicist did. Game mode is on, also Input signal plus.

The first attempt turns the screen utside down in a scaled 8K (4K) it seams like.

The second attempt just turns screen back to how it was.

The EDID seams to change unpredictable between 703F and 7040.

The SAMSUNG 703F EDID seems to be the best EDID.
The SAMSUNG 7040 EDID is missing VRR stuff (both HDMI and AMD).
The EDIDs from the AGDCDiagnose output are missing 7680x4320 50Hz and 60Hz modes and the HDR10+ vsvdb.

The two AGDCDiagnose are using 4K60 10bpc 4:2:0. The first is scaled down from 8K with billions of colors, while the second is just 4K millions of colors.

I think you'll want to make sure the EDID override in the override file matches the 703F EDID from SwitchResX.
Also, override the pixel clock max in Frequency Range to 2400 MHz.
And post the AllRez output so we can see all the modes.

if I remember correct, 8k 50hz and 60hz was also missing from the AgdcDiagnose that ZombiePhysicist posted, without that causing the problem. Still he was able to get 8K@60hz.

Keep in mind I just like to replicate ZombiePhysicist, so I don’t really need HDR. All though HDR popped up as option many times when using CableDeconn at lower resolutions. It looks like ZombiePhysicist were able to get the connection into 8bit. There was a command you mentioned to enable 8bpc on MacOS?

I would like easy steps on how to replicate. The Samsung EDIDs doesn’t mention the 2090.06Mhz mode, so I don’t understand we that even would have a chance. But 8k with 8bit seams supported by the Samsung, from 24hz to 60hz. In theory it should then be possible to connect on e.g. 30hz, which would also be fine with me.

>EDID override in the override file matches the 703F EDID from SwitchResX.

Not sure how to change the override file? Is that the settings on the first tab in SwitchResX?

I don’t know about AllRez, need help.

That was for changing the default bpp for DSC but it doesn't look like your adapter supports DSC.

Thanks for all your efforts and reports on the Intel side of things, but have you been able to see any success on Apple Silicon? I need 8Kp60 10bit 4:2:0 support for my MBP 16" M1 Max. I've yet to read about any success with 8K resolutions on Apple Silicon however (from any reputable source at least).
 
Sorry. life/work has interfered here. Hopefully next week I get my 85” monitor mounted at my desk so I can use it full time. I want to run a few more tests on the intel side that @joevt asked of me. After that I’ll run some tests on the apple silicon side.

I’m definitely interested in the apple silicon results as well as some pics of the 85” monitor at your desk!

So rtings.com re-tested the dithering effect on the QN900A in game mode, and they said that there is still minor dithering (see the review comments). @ZombiePhysicist I can’t really tell from your close-in images, but if you look close enough, is the dithering truly 100% gone, or just gone enough that it doesn’t bother you?

I can’t tell you “truth” but can only report it as my eyes see it. As my eyes see it I don’t see any apparent dithering. When I photograph it, the photos do show some dither artifacts, but I do not see them with my naked eye even when I looking for them. I have a post back in the thread with photos pointing that out.

at least 2 caveats. First, while the dithering is invisible to my eye and several people I showed it to, the dithering you see in the photos is slightly more pronounced than the dithering effects you see on the 30” Cinema Display in photos. But even that has dithering artifacts that show up only when you take a photo and that I cannot see with my naked eye.

2nd, I am not daily driving the 85” display yet, it’s off to the side for testing. Hopefully this week I finally finish building my custom mount over my desk and drive it daily and will have more to say on it.

lastly, it is a night and day difference from non game mode. In non game mode I wouldn’t even call it dithering, I’d call it more akin to halftoning in its effect. It’s super pronounced. In game mode, it Al just looks like solid colors. I cannot speak to issues of “super color fidelity” because I’m not a color pro. Further, these are bases on a 420 color space, and the screen is capable of doing 444 I think, so if/when we get a hookup using 444, I would suspect the display should only get better in fidelity.

for reference, here is a post showing shots not in game mode and you can see the color rainbow button is halftone dithered with obscenely easy to see dithering. There are no pure colors just haltoning. https://forums.macrumors.com/thread...-on-mac-pro-yes-you-can.2309750/post-30733329

this post shows the screen now with game mode on, and you can see there is basically little to no dithering, and the 8k display doesn’t look much different than my 30” Cinema Display:

I received the Mac Studio yesterday and unfortunately things aren't going smooth with the Dell UP3218K.


While it will recognise both inputs at 3840x4320 pixels the extended display appears to have timing issues and the main display is even mirrored behind it.

I was really hoping the M1 Pro / Max would solve that issue but alas.
