Using an 8K TV as a macOS Computer Monitor

I have a dream. A dream that one day I will be able to use an 8K TV as four seamless 4K monitors. I just can't figure out how to make this work. 

Yes, I could get this to work on Windows, but over the last two years, I've become an Apple fanboy. I just spent an ungodly amount of money on the new M3 Max MacBook Pro, which can power an 8K display at 60 Hz, but that isn't the problem. 

The problem is that I can't find any software that will split one giant monitor into four virtual monitors (I can for Windows, but not macOS). I need the TV to act as four different displays because when I full-screen a window, I never want it to fill the whole TV. I just want it to fill the quadrant it's in. 

The other issue is Mac's menu bar. Instead of sticking a menu bar on top of every application like Windows does, macOS sticks it to the top of each display. This would be incredibly frustrating to deal with on one giant monitor. 

Watch the video above where I explain my dilemma in greater detail, and let me know if you have any ideas of how I could pull this off.

There is a possible solution that may help. Not perfect but a possible workaround that may be good enough for you

It won’t truly split your 8K into 4 x 4K monitors but will almost achieve it, and may partially mitigate your menu bar issue to a degree

Download and install and app called “Window Tidy” and with it you can set ‘zones’ on your screen that you can drag apps to and they will snap to fit that zone. Also as the apps are not ‘maximised’ some of the menu bar will stay at the top of the app window.

Cheap and easy if not perfect but worth a try?

Best wishes

Thanks I'll try!

So, I've done this, with a M2 Max MBP. I can highly recommend Window Tidy or Mosaic.

Here are some of my notes: https://scottstuff.net/posts/2023/10/10/samsung-8k/

The menu bar is an issue, but it's not the *biggest* issue. Getting all of the random color settings so that text isn't terrible was surprisingly difficult, but I'm happy now.

You should flip your speakers for more stereo separation

Try reaching out to Andreas Hegenberg, he made the app Secondbar.

Hello from the future :)

Was looking for a solution to spend $1000+ on something and found this post :)

So, I also want 8K on my Mac M1. And it seems doable.

I'll need a 8K monitor and this thing, which will allow me to make 4 x 4K streams which then will be combined in the monitor via Multi View feature (theoretically).

I don't think the things you linked do what you think they do. You linked docks that have 4, 4k outputs. That is very different than an 8k switcher that sends 4 different 4k sources into a single 8k output.

There is MultiView feature in Samsung which allows to show video from different inputs in different parts of the screen.

MacBook -> via USB-C -> DisplayLink Adapter -> separate cable to each HDMI port.

PS: having two 2-port DisplayLink seems like better option.

Can it show 4 different 4k signals at once? Last I checked it could not

Manual says it can: https://downloadcenter.samsung.com/content/UM/202404/20240426190921443/B... (With 8K models (QN7**C Series or higher), you can configure a view with 3-5 screens.)

I think I looked into this a while ago. It adds strange black bars and It's not full 4k https://www.youtube.com/watch?v=c4ILAzgRNLw&ab_channel=SamsungSingapore
