I'm using my Studio Display with a Intel based Macbook Pro 16" from 2019 (I9, 2.3, 5500). Viewing videos on the Studio Display is stuttery and not at all pleasant to watch. Watching the same video on my MBP built-in display it is buttery smooth. This happens no matter which video viewer I use, Youtube, Netflix, built-in Preview etc.. Youtube is probably the worst. I tried playing around with the scaling settings for the Studio Display but it doesn't get better. Could it be the combination of my Intel MBP with the Studio Display? Has anyone got similar issues?
Got a tip for us?

Probably a CPU/GPU issue due to the fact it has to power an external monitor now. Even without an external monitor I always had issues running things like a 4K YouTube video because of this. Check your resource monitor to see what the cpu, memory, etc are doing when the display is connected.
I was hoping that buying an M1 isn't the solution ?. Having an eye on sensors when plugging the monitor in shows that power consumption climbs from about 16 Watts to 27 Watts. The Radeon then takes over as the built-in Intel was active beforehand. However, I still don't understand why the Radeon wouldn't be able to handle a single 5k monitor.
A single 5K 27 inch Display (Apple Studio Display) + a single built-in display. So that's You can experiment with disabling everything, with transparency, and so on.
Or IDN, maybe changing reference mode would help?
Because this is ridiculous. Your system is a real tough one, maybe because of its (display) internal dodgy behavior?
Interesting idea as I haven't thought that reference modes could impact performance. I tried some of them but could not really tell a difference. If it did, it wouldn't be of great help for my situation as I bought the Studio Display for the only reason of having 600 Nits available in SD.
According to Apple, it should work:
MacBook Pro (16-inch, 2019) Video Support
Simultaneously supports full native resolution on the built-in display at millions of colors and:- Up to two displays with 6016‑by‑3384 resolution at 60Hz at over a billion colors
- Up to four displays with 4096‑by‑2304 resolution at 60Hz at over a billion colors
- Native DisplayPort output over USB‑C
- VGA, HDMI, DVI, and Thunderbolt 2 output supported using adapters (sold separately)
It sounds like it’s under clocking the GPU to save power, which has a byproduct of generating less heat.
I am not sure what this mode is doing exactly. In terms of heat and noise it helps a ton with my 16-inch Intel Laptop. Thats the reason I was keeping it on even plugged in. The downside seems to be reduced performance, but only barely noticeable. The stutter issue is still very present even with this feature turned off.
