3x4K monitor with Macbook Pro 15'?

Post by chromexyz »

Hi everyone!

I'm having trouble figuring out if this is possible. I have a gig next week and they told me that I could run three 4k monitors as one screen using 3 HDMI outputs. The thing is, is even possible on a macbook pro?

I have 4 USB-C outputs, one for charging, the rest for screens. Technically, I have the outputs; but do I have the power? These are my specs:

  • 2,3 GHz Intel Core i9 with 8 cores
  • 16Gb RAM
  • Radeon Pro 560X 4 GB
  • 500Gb SSD
I have no plans to use any effects. Just playing clips. Do you guys think is going to work out? There's an option of using just one 4k screen as a backup, but if I can go with the three I would like to.

Possible: Yes
FPS above 20 after running for an hour (thermal throttling): Probably No

So your output screen is almost 8K eh?
Do you have 8K content for this event?

Yeah, the res is: 11520 x 2160. All the footage is in that resolution. They told me they could rescale from 1080p but I don't know how good the quality is gonna be.

What happens if you render out a 10 second clip of static/noise in that resolution, and then add that clip into your comp (same resolution) and play it back, outputting to (3) NDI 4K outputs?
That would be a good benchmark to see how well it will perform in the real world.
Be sure to let it run for 3 hours to see how your thermals do.
