Command "set" not working on latest MacBook Pro 16" #32

On latest MacBook Pro 16" (running Catalina) list works fine but running set with any of the available resolutions doesn't have any effect. Any ideas what the issues could be or how this could be fixed?

same here. MacBook Pro 16" (running Catalina)

$ sudo screenresolution set "3072x1920x32@60"

I forgot how I set to 3072x1920 back when I bought this mac 😩

For for those you have the same issue: in the meantime you can use the GUI application RDM https://github.com/avibrazil/RDM

Same, but not on a MacBook. I have an ultrawide Samsung split into two monitors. List shows options correctly, and when I select the current resolution it dumps out the same error as mentioned above.

This tool looks awesome! https://apple.stackexchange.com/a/450370/53510 led me here. I'll be so excited if we can get this working.

Unfortunately on my 16" MacBook Pro, this happens:

I have a 42.5" Dell display plugged in via USB-C. I don't need the built-in Mac display to be turned on (although it's fine if it is, as long as it's identical to my main external display).

I wonder if the difference in precision between 60 and 60.000000 matters?

Gerst20051 commented 1 year ago

I also get an error when trying to set the resolution of the built in liquid retina xdr display that supports 120 hz. The command does work to update the resolutions of my external monitors though.

[$]> screenresolution set 1728x1117x32@120

Error: mode 1728x1117x32@120.000000 not available on display 0

That was the default resolution. When I tried setting it to a resolution from the list output it worked for me.

Thanks for your comment. Yeah, I'm still not sure what's wrong with mine:

The issue is the float compare, this works around it, but maybe better to check if the floats are "close enough" to each other?
