Resolution Woes

[phil_mw60]

Hi,

I have my RPi connected to a fairly small 32" TV via the HDMI output and by default it is using 640 x 480 resolution, which is of course very small and means I have to scroll around the screen a lot.

I've tested modifying some of the settings in /boot/config.txt e.g uncommenting hdmi_safe=1 and when I do this I get a very high resolution which is at the opposite end of the scale! Ie I can hardly read the text it appears so small.

Does anyone know how I can set a mid-size resolution maybe 800 x 600? When I run the following command:

# /opt/vc/bin/tvservice –m CEA

I get a message saying the only available resolution is 640 x 480!

Thanks for any help.

Phil

Edit:

I meant 24" TV not 32"!

Edit 2:

I've modified the
#framebuffer_width and #framebuffer_height parameters to 800 x 600 and this seems to have given me a better resolution.

hdmi_safe=1 is supposed to force hotplug and set a resolution of 640x480. Instead, I use the force hotpug line (because I have an HDMI to VGA adapter) and use the framebuffer lines to set my desired resolution. The hdmi_mode and hdmi_group are supposed to allow setting for fixed resolutions but I couldn't get them to work at the resolution I needed.

Thanks mobius, I've also used the framebuffer lines to set my required resolution.

Now I just need to play around with the overscan settings as there is an area of black space around my Pi display which could be used!

Thanks.
