As the OP explained in the original post, he wants those rules to work
conditionally, if certain screen resolution is detected.

I don't know how to do that internally in Emacs, but if one is running
under Linux, the command "xrandr | grep \*" will tell you the
resolution and frequency of the monitor. Maybe one can have Emacs
execute this and parse the info...

HTH, :-)
