IDK. I am no expert but I bought a 2K LG monitor for my M1 MacBook Air and the fonts were very blurry. I returned it and bought a LG 4K monitor and scaled it to 1920 x 1080p and it is so much sharper and videos look so much better.
144/60=2.4x - this how much more scaling work GPU has to do in case of 144 Hz 4k monitor. So while on 60 Hz this settled as being OK (M1 GPU probably has some hardware accelerated scaling built-in already) higher refresh 4k monitors have to wait. Even the fastest 16" MBPro has 3456x2234 120 Hz screen, still requiring less scaling work than 4k@144 Hz. But honestly 4k@144 Hz is an overkill even for top gaming PCs. My friend has just built such a machine around i9 11900 and RTX 3090, yet it's still not capable of playing high fps @4k. Basically he plays 1440p most of the time in all games that benefit from 144 Hz of his LG 4k display. He had to admit that now he'd just buy top 1440p monitor saving some bucks.Just wanna add onto this thread as I’m in the process of returning an LG 27” 4k 144hz monitor after getting horrible GUI lag with my music apps when using it scaled at 1440p when using it hooked up to my MBP 16” M1 Pro laptop
The display looked amazing and for the most part it was fine, when just navigating the OS. I went for the high refresh rate as I wanted something close to the really fluid 120hz pro motion display on the laptop itself but when I’m inside various music production apps, you can really feel the sluggishness when interacting with the UI, especially at 144hz. I’m gonna wait until apple release a promotion display of their own to avoid these scaling performance degradation issues. Back to 1440p for me.
Repeating what I said in another thread. I tested that monitor at all different refresh rates to rule out any performance issues that could arise from having a high refresh rate display, 60hz all the way up to 144hz. The same UI lag occured even when I put it all the way down to 60hz. When zooming in and out my projects in various different audio apps (Ableton, Bitwig & FL studio) the UI was insanely choppy when using 1440p scaled, you could see & feel the dropped frames.144/60=2.4x - this how much more scaling work GPU has to do in case of 144 Hz 4k monitor.

So that's surprising to me then. Do you have any chance to connect "ordinary" 60 Hz 4k display to check if it is repeatable on this also?Repeating what I said in another thread.

Yeah I grabbed an older 60hz LG 4k monitor that I have spare and experienced the same on that also.So that's surprising to me then. Do you have any chance to connect "ordinary" 60 Hz 4k display to check if it is repeatable on this also?
Looks like these two apps for some reason make heavy use of GPU (I think strange for DAW applications). I wonder if for instance Cubase or Logic Pro (this one is Mac exclusive) would create the same problem? I use Exposure X6 which uses GPU for image manipulation quite heavily and while there's some delay on 4k as compared to native 1440p monitor I'd say it is passable, especially that I have MBP 2019 with i7 and Intel IG and M1 are considered much better in this regard.Yeah I grabbed an older 60hz LG 4k monitor that I have spare and experienced the same on that also.

Yowch. Will this still be an issue even with the M1 Max at 32gb RAM?It won't, I've got the same model and experienced issues. The only way to avoid these issues as far as I'm aware is to go for a 5K monitor.
It depends on an app. Seems like apps using properly metal framework are working just fine in scaled resolutions on 4k screen, performance is good even on multiple 4k screens.Yowch. Will this still be an issue even with the M1 Max at 32gb RAM?
This was really helpful! Thank you! Since I’m also upgrading my cpu and gpu to 10/16 maybe this won’t cause major performance issues? Plus, I only use 1 ext display.It depends on an app. Seems like apps using properly metal framework are working just fine in scaled resolutions on 4k screen, performance is good even on multiple 4k screens.
