Hi guys,

I have an Amiga one X5000 and bought a ATI Radeon Sapphire X1950 GT 256MB GDDR3 DUAL DVI-I/TVO
on ebay.
https://www.ebay.at/itm/176603571492
It's conncted with a DVI-to HDMI cable on a flat monitor.
Worked with OS4.

When i boot the X5000 with a USB stick it boots up and a few seconds later the monitor goes black and says "no signal".

Maybe the videocable is the issue ?
Or any other hints ?

Regards.

What resolution does the monitor have?

If it is above FullHD the autodetection could have chosen a mode that would only work to over DualLinke DVI.
Either use a smaller screen or see if you can access the early boot menu with holding left mouse button.
Once you booted into a lower res make sure to save that and you should be able just run that on any screen.

You can also hold ctrl key while MorphOS is booting to force a low-res fallback mode.

Thanks all, i used an older Monitor and i am able to boot and install without issues.

Thx again.
