Is it possible to run a 4k 144hz display and a 4k 60hz display off 1 thunderbolt 4 connection with alt dp mode?

Not looking to play games I just want a smoother desktop
I have a framework 13 laptop with a 1240p inside

4K 144 Hz requires a bandwidth of 31.35 Gbps

4K 60 Hz requires a bandwidth of 12.54 Gbps

So in total 43.89 Gbps

 

This means you'd need a USB4 port capable of 80 Gbps and one of the monitors would need to be capable of Multi-Stream Transport (MST) at those speeds to be able to daisy chain it. (~edit: of course it's not just the speed of the USB port, but actually which DP version the GPU behind the DP alt mode supports… the full uncompressed bandwidth would require DP 2.0)

 

If the GPU and monitor(s) support Display Stream Compression (DSC), then you'd be able to get away with a slower USB4 port, e.g. 40 Gbps. Unfortunately I don't know what type of USB4 port the laptop has, but I'd suspect it's more likely a 20 Gbps one.
