Nvidia Surround output during boot up?

[Legion495]

Hey guys.

 

Since AMD really flawed Vega bigtime I consider going back to Nvidia again.
At the moment I use Eyefinity.
I had a 970 in the past running NvidiaSurround and there was one thing that bugged me.

During boot up the NvidiaSurround setup(With 1 to 3 DPadapter and without) would not display anything on my screens connected with displayport, only on a fourth monitor I run direct from the GPU with HDMI.
Only after Windows loaded I get a output(Drivers ha?).

With Eyefinity the output of all my monitors work from the getgo even if displaying all the same(like only Bios and stuff).

I should mention I have every DP adapted to HDMI which basicly means all monitors are connected via HDMI.

 

I wonder if this is still the same for the 10series of Nvidia GPUs. It would be great if anybody knows that.

I'm not entirely sure you can, 

 

In most cases i've seen any other monitors will get a signal once the computer has properly booted up,

i don't believe the graphics cards will change this, it's more to do with Windows  

[Legion495]

Like I know AMD cards do it. Like sure you need to install the drivers(I believe, was long time ago^^), but once you did they work before I even come to Windows(Bios, other applications during bootup).

I used a 7870 with Eyefinity-All outputs working

A 970 with NVsurround-Only HDMI and DVI should work too(DP not). DP only working if booted into Windows.

And now a 390 with Eyefinity again.-HDMI and DP working

 

It is more a thing for convenience as my displays turn off within 10 seconds without signal(that was a bad decision to buy those^^) and I know both solutions tend to fail which ends up in one or two monitors not working, blackscreening and it needs usually a restart to fix it->That however is down to Windows, because it only happens if Windows loaded.

 

And it is super helpful if you troubleshoot a lot and they work without Windows. I like prefer the way Eyefinity handles it or how the GPU seems to handle that during bootup. And I wonder if Nvidia changed something for that  One thing is clear. That is so 100% down to the GPU my friend.

 

Actually I think I need to ask this in Nvidias Forums tho. Like nobody seems to really know it... Well I'm one of those few people with 3+1 monitor setup

When I used my 1080, I had to run two dp2dvi adapters. Cant even remember which went to the bios. Never really cared or paid attention which one it was. Never go into bios often enough on my surround rig.

[Legion495]

Not both? Like in the Nvidia forums one using probably 3 dp directly work. It seems once you have adapter between Nvidias DP output is like nothing.

[Mick Naughty]

Well all of my monitors are dvi. My 1080 only has one dvi so I have to adapt two dp's.

Just tell me. Do they all post BIOS or not?

 

I heared something about the lines that Nvidias driver should have the option to put Displayport to sleep(I think that is a dead end tho). And DVI is more or less the same as HDMI that said. If it works for DVI it most likely does for HDMI too. I read about a 970/980 BIOS issue. Seems that topic is way more complex than I first thought.

I've never, ever had bios show up on more then one monitor. Never seen it online either. Didn't think it was even coded to do so as it would be pointless. 

 

I use dvi as it supports 120+ hz unlike hdmi. Not gonna surround game in 60hz, maybe if this was 2005 or something.

Don't think it is pointless. If you only use DP that is quite a issue... all other stuff is subjective and down to the user anyway.

You basicly told me what I need to know.

Actually I thought Nvidia could easily output on everything before any OS is loaded  For me it is a convenience thing due to my monitors and if I troubleshoot(which happens more often than I like).

If they would manage that I would actually buy Nvidia right now. 

[Mick Naughty]

Don't see how anything else would show up if there isn't anything there. Would have to go out of their way to make that even plausible. 

[Mick Naughty]

If you just hit your button to go bios like normal and it will come up. Isn't gonna span across more then one but it still works. 

[Legion495]

It is not about spanning across more than one. BUT it should display the BIOS on each monitor connected. Duplicates.

Like every monitor gets the bootup signal with post and what not.

Every monitor works independent until the OS loads to join them, that is clear.

 

Didn't even think someone would expect to understand it(what I wrote) as NvidiaSurround/Eyefinity software joined monitor before the OS loads^^ I know it is software managed to join the Displays over the OS and more so over the vendor GPU driver if it were for that matter. 

 

However I came to the information Nvidias GPUs do not seem to output over DP during bootup. People with Gsynch displays actually reported this issue multiple times as they run over DP... might be down to faulty cables? Display? or even GPU? Whatever it is it seems to be down to Nvidia  Some people write about RMAs and then it worked. This just lets me avoid all of that.

 

My Eyefinity works that way and I hoped for the excact same experience. Like my monitors turn of after 10 seconds and my ssd is too slow for a 10 second bootup into Windows^^ So to me it is annoying and how much do you change monitors?^^ like never.

It doesn't default to duplicate. Haven't seen an os/nvidia do that since like 1999. If you have 14 monitors on the rig it shouldn't wake up all of them just for the bios. The bios wouldn't have that kind of power anyway. The most basic form of computing, surround can't even be running nor can it control more then one output.

It doesn't even support so many monitors anyway. I like it. I can troubleshoot over DP without a extra monitor.

I expected it is down to lowlevel stuff in the GPU anyway. But I think it is quite a hefty detail that Nvidia missed a output on DP it seems.

 

If you have 14 Monitors you like use them anyway I guess  So it would make sense to wake them up.

And it shows if all work. Like without OS, because we all know a OS can screw up display output... I guess we do(My experience with the software joined displays says some might turn black). Easy step to isolate a hardware issue imo.

 

I do not think it would be a major issue, but more of a advantage to have a early output for such simple reasons like seeing the hardware works.

Might be a thing for 14 monitors(to not post), but then I expect special software and or hardware anyway.

[Mick Naughty]

If you're in the bios there isn't anything running. So they would have to go out of there way to make it work, which again is pointless. The hole point of bios is to have direct access, so running program and would continue to add to the problem. 

 

Something not displaying during bios has absolutely nothing to do with nvidia. My bios shows just fine over dp on my second rig. 

When it used to not display, I could still hit the button like normal and it would come up.
