BUSH Set Top Box won't work with an ACER LCD Monitor

[ljcox]

I have an ACER model P221W LCD Monitor and a Bush DFTA10HD Set Top Box.

I use the ACER monitor with my computer but would also like to occasionally use it to display a TV picture from the Bush Set Top Box.

The Set Top works with another LCD Monitor (not an ACER) via the VGA connection but it will not work with the ACER monitor.

It also works with my TV via the VGA connection.

When I connect it to the ACER monitor, the screen shows a message "Input signal not recognised" or words to that effect.

The Bush also has a HDMI output and the ACER has a DVI input, so I connected them via a DVI cable & HDMI converter. But the same message appeared on the screen.

Does anyone know why? I asume it is due to the wrong data DDC data.

Any assistance will be appreciated.
