How to get 24bit color with wide screen (Now I getting square screen in vnc client)

Solution

Simply start vncserver with the command:

/usr/bin/vncserver -geometry 1024x768 -depth 24 :0

• geometry: define the resolution
• depth: define color depth

If you want to automatically start it at boot, add it into /etc/rc.local

sudo cat "/usr/bin/vncserver -geometry 1024x768 -depth 24 :0" >> /etc/rc.local

Are you using VNC Viewer client?

[Tung Tran]

If so click the Options button at the bottom of the VNC Viewer dialog and choose the Display tab and set the values you want to see if it gets effect.

I set the display options but stil screen is square and i think 8bit color !!!

[Tung Tran]

Make sure to enter the right session for the server address on the VNC Server box. As my start command, it should be your_server:0

Thanks i get 24bit color but Still screen showing square !!!

Have you tried different resolution from my sample -geometry 1024x768? Use the one which you think fits to your current Windows screen.

[Tung Tran]

Note that you can create multiple sessions for your vnc. So you don't need to stop your current session, start a new one, eg, /usr/bin/vncserver -geometry 1280 × 720 -depth 24 :1 and enter your_server:1 in the VNC Viewer box.
