One out of three monitors not displaying on boot...

On the road....
I have 3x24" monitors running in Nvidia surround @ 5760x1080 recently on boot I've found the first (left) screen stays blank on initial boot, if I go into task manager via ctrl-alt-del and reboot they fire up perfectly.

This has only started recently and has stayed the same despite a few graphics driver updates - even after running DDU.

Any suggestions?

I'm running two GTX 580's in SLI and other than this they perform perfectly.

Thanks.

Initial boot...



After reboot....

 
Does the same thing happen when not in SLi mode? How are all the monitors connected?

Not tried it in non SLI mode and the monitors are connected as per Nvidias instructions, on the 5XX series they have to be connected in a specific way for surround to work which I discovered after a lot of head scratching!


I'll turn off SLI & report back....

What are the requirements? Are you using any adapters?
 
Just disabled SLI, powered down and then turned back on, booted up just fine but only one screen....



Not ideal especially given its worked fine previously....

Is it the HDMI monitor that has the issue?

And turning off SLi didn't allow Windows to know about the other two monitors since surround makes it thinks there's only one, so setting the other monitors in extended mode should fix that.

Could perhaps be the HDMI monitor, thing is, I need SLI and my surround configuration to utilise my three monitors,for my games, as I say, previously its worked just fine but only recently has stopped booting correctly.

Setting my other monitors in extended mode is all well & good but I want surround working from the get go which it previously did just fine...
 
It's just to test to see if the issue still happens in non SLi mode.

And check which port the left monitor is connected to :p.
 
Seems to fire up happily in non SLI mode although only one monitor (middle) the left hand monitor is connected to the top card, if its in the bottom card Surround won't enable, #3 monitor ,the HDMI one, is on the bottom card also.

Haven't tried the HDMI in my top card as its a mini HDMI port and I cant find my mini HDMI lead although the Nvidia configuration page I linked to earlier specifically says for my configuration the top card only needs / wants one monitor connected, I don't think DVI or HDMI makes any difference.
 
So it's the top card that's having problems then. What if you connected a different monitor to that card? Same problem?

Won't enable Surround at all if I swap my dvi's top to bottom (as I've just tried) if you see what I mean as it seems to be against the configuration which Nvidia specify, surround won't enable. :/
 
Oh FFS! I've just put it back to how it initially was and now I can't enable surround at all, it just locks up. :(

I mean, swap the DVI monitors around, so the bottom DVI is connected to the top card, while the top DVI is connected to the bottom card. It will still match the Surround specification. That way if the same thing happens to the other DVI monitor, then it could be the top card having an issue.

Tried that previously but for whatever reason it wouldn't enable surround unless I've got the DVI's as they currently are, left hand screen in the top card, middle screen (DVI) and right hand screen (HDMI) in the bottom card, can't see why it wouldn't work as you say, but it seems not to.

I've removed the second card and it boots fine with one display, boots fine if I replace the top card with the removed bottom card also so I don't think the card(s) are faulty but for the life of me Surround won't enable at all now no matter how I try to connect it.

Wish I'd just put up with rebooting straight after startup now! :o
 
Forgot to say in my OP that on boot the left hand screen POST's fine giving my bios details etc and then the blue Windows 10 logo, it then goes blank upon going to desktop as per the image.

Well, it did, won't go into surround at all now :/
