Pal doing the work as very recent eye and carpal ops makes me less than technical.
Working backwards. Computer ceases to be a computer as soon as the card is slotted in. No post checks as far as we can see. Though the mega-card is able to display those 3 items in mono.
It does not dual output with the on-board VGA - well, PC is basically dead anyway.
700 watt PSU with new extra leads to card.
Card is an ebay used item, but vendor experienced and 5*. However, I didn't want to risk this PC trying it out and my Lenovo quad i5 is so picky and I don't want to risk that as must sell it in mint condition.
The target MB is really too small for card. One heck of a job to keep it and its 3 fans clear of stuff.
PC is running okay now with another card - which doesn't come close to the native 4k of the intended monitor.
It was being tested on HDMI with monitor selection working okay. (well, showing the selection) The VGA trial was just to see if we could see any means of loading the card's software. That VGA plug was on the MB and was disabled the moment the 'new' card was slotted in -
so, I took that to mean it auto switched the on-board graphics off, though I agree it would be worth another poke about in the BIOS. As mentioned, I don't want to lock myself out by being blind on all outputs. Not sure about BIOS reset on this board.
My guess is one would need the new card running in basic mode so that the drivers could see it as they were loaded.
As I see it now, the only safe option is to fish out another MB just to test the new card. Trouble is, this is just playing and I'm not cracking on with a plethora of other tasks. I thought retirement was going to be all play but far from it.
