I have a Motorola vip1910-9 set-top box provided by my ISP. It's a simple Linux based STB and I'm quite satisfied with it's capabilities. Unfortunately I could not hook it up to my TV with a standard HDMI cable only through scart.
After spending hours on the net looking for a solution I came over a Swedish forum, which gave away the solution.
- Reboot the box, either by power cycling or from the remote
- Press the Menu on the remote when the boot starts
- Change the output to the resolution your TV can do
- save and reboot
