Hi Ive replaced my X1900 with a Sapphire HD 4870 1 GB card. Im getting some undesirable startup behaviours from both of the video ports and was wondering if anyone had encountered the same. Many forum searches have found nothing similar. If I use the lefthand port (when looking at back of machine) I get a boot screen after which everything goes black and I get no more display signal. The right hand port works fine - boot screen and general use - but only if i plug in the display after the chime. If the display is plugged in from the very beginning then I again get no signal. So I have to unplug the display and restart. Ive tried detecting displays via a system prefs hotkey and an apple script in my login items but this has no effect. I flashed the card via ZEUS. Ive tried a few different ROMs via FREYA and others online to no effect. Its not the end of the world - but it would be nice not to have to keep unplugging/replugging the display. Any ideas? Cheers!
