Black screen when switching on HDMI

Hi!
Until yesterday, Kodi were running on my laptop with my Nvidia GT540M. Because Nvidia isn’t able to do Vsync on Linux, I switched to my Intel GPU profile, now I don’t have tearing anymore but have problem with HDMI…
When I start Kodi, Display Mode is set to Default, the result is that Kodi is displayed on my TV connected through HDMI, but not in full screen (in fact, I have Kodi interface on the upper left side of the screen with the resolution of my laptop screen, and the rest of my screen is black).
So, I switch display mode on HDMI1, but then, I have a complete black screen on My TV. However, I can hear the sound of kodi when I use my remote or my keyboard. I’m obliged to reboot kodi, but the Display mode come back to Default (so display is on my TV but not in full screen).
I don’t have this problem if I come back on my Nvidia profile. I can use any other app (VLC, Dragon, Mozilla…) in full screen on my TV.
Any idea of what can be the problem?
Thanks!
