After a few boot up problems my Pi is now usable but I don't seem to be able to alter screen resolution.

I have booted using composit and hdmi, the former is a bit big and the latter is too small, when I go in to monitor settings I only seem tho get the choice of auto and one specific setting.

Any advice re screen options appreciated.

I don't recommend using composite video if you have access to an HDMI display, and it sounds like you do.

Anyway, I'm going to assume that HDMI display is a 1080p 60Hz TV for my example code, and that you want to make the pixels larger by sending video at the resolution of 720p 60Hz. Once again, just an example.

Code: Select all
disable_overscan=1
hdmi_mode=4
{sig} Setup: Original version Raspberry Pi (B, rev1, 256MB), Dell 2001FP monitor (1600x1200), 8GB Class 4 SD Card with Raspbian and XBMC, DD-WRT wireless bridge

Thanks, that has helped, I'll explore the config file a bit more.

Strange though, despite entering your suggested settings when the display started it showed as 1184x624 but the screen display was much better than previous.

The composite lead is just more convenient, the HDMI lead is so thick the board then doesn't lay flat.

Re your suggestion, I have a Sony Bravia, the manual states 1920x1080, not sure if it is i or p or cannot see in the manual if it is 60Hz or 50Hz.
