Hi there!
Okay just to double check, this image below is a VGA cable;
1)

So are you using one of these (above) with a HDMI to VGA converter or are you using a composite cable like this one (below)?
2)

Either way I think you can probably solve this by modifying the settings in config.txt. I’ll give you some suggested changes below. So config.txt is a small text file that you can edit either on the Pi itself or on your Windows PC but putting the SD card into it. It should be one of the files that you’ll see when you explore the SD card. From on the Pi through you can modify it by using this command;

Code: Select all

sudo nano /boot/config.txt

When you have modified it you press Ctrl – X, y and then enter to save and quit. Reboot the Pi for the changes to take effect.

Here is the official documentation for what video settings you can use;
http://elinux.org/RPiconfig#Video_mode_options

Okay so if you're using 1) above then try this;

Code: Select all

hdmi_safe=1

If its 2) then try these;

Code: Select all

overscan_left=24
overscan_right=24
overscan_top=24
overscan_bottom=24

Increase the numbers to get the picture exactly how you want it.

Regarding the ethernet issue, you can try something like this; http://www.youtube.com/watch?v=8z3V8LJIy8g
