If I start the pi withe the display unplugged and then plug it in later, the screen resolution is too low. I can only solve this by restarting the machine. Is there a way to solve this without restarting the machine ?

Why do you plug in your display after the pi has booted? I think the simplest way to fix this is just plug the cable in before the pi boots.– MichielvkCommented Mar 10, 2016 at 13:57

As far as I'm aware, it's only by hardcoding a specific resolution into /boot/config.txt, e.g.:
hdmi_force_hotplug=1
hdmi_group=1
hdmi_mode=16
Should guarantee you HD resolution (1080p @60 Hz) if you plug in a cable after power up, and in my experience will work with most modern TVs and monitors. For a complete list of the possible options see here.

Set resolution into /boot/config.txt directory..
Force the monitor to HDMI mode so that sound will be sent over HDMI cable
hdmi_drive=2
Set monitor mode to DMT
hdmi_group=2
Set monitor resolution to 1024x768 XGA 60Hz (HDMI_DMT_XGA_60)
hdmi_mode=16
Make display smaller to stop text spilling off the screen
overscan_left=20
overscan_right=12
overscan_top=10
overscan_bottom=10
