raspberry : screen resolution

[slhoir]

Hello,

I acces my raspberry only with teamwiewer, but the resolution is very lower : 640x480. My raspberry has no keyboard, no mouse and no screen.


How to change resolution ? If i try to change resolution with "tvservice -e 'CEA' " command,  nothing change from teamviewer (the mode is probably changed only for HDMI connector)

This problem may not be a teamviewer problem because if my raspberry is connected to my tv, resoluiton is high. My problem is only when my raspberry is not connected to a screen...

Thank you

I needed to modify parameters
Framebuffer_width=1280
Framebuffer_height=720
in /boot/config.txt, and start again th raspberry.
