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.

1. Reboot the box, either by power cycling or from the remote
2. Press the Menu on the remote when the boot starts
3. Change the output to the resolution your TV can do
4. save and reboot
