Rig of 6 gpu's does not boot if no display is plugged in

[ChipsSlave]

Hello all,

I have got an issue where my rig just simply does not boot into the windows if no display is plugged in. System starts, internet socket flashes green, gpus power up, everything seems normal but windows do not load. Rig is not visible on local network, does not connect to router. Only after I connect display into one of the gpus system boots up with no problems.

Any suggestions?

Sounds like you need an HDMI dummy plug.

Oh the joys of mining on windows. Switch to linux and you wont have that problem. You will also have a much more stable miner.

Really? There isn't anything else that I could do?

What type of gpu's and board do you have?  Did this just all of the sudden start happening or has it not ever worked?  But yeah, I would first try the hdmi dummy plug.

I never had any problems booting the system before as I was setting the rig up whilst the screen was always plugged in and now when everything is set up I must plug the monitor in to boot the system. Never ever had this kind of problem with any other computer systems.

I have a Vega 56 rig (different mb) that has the same problem and I have yet to figure out why it won't boot without a dummy hdmi or a monitor plugged into the gpu that's in the pcie16 #1 slot. 

Even using igpu when I need to plug a monitor into that rig fucks everything up.

My 1070ti rigs ... No issues at all with that sort of thing.

Honestly though, for me ... If it's going to take too much time to troubleshoot and you can fix it with a ten dollar dummy hdmi, that's what I'll do.  I spent two hours last weekend trying to get igpu to work and it's just not worth wasting any more time on right now.  As long as the rigs are hashing, we're in a good mood.

What happens if you boot up the system with a monitor installed and later, when mining has started, you just take out the monitors power cord from the outlet?
I use my rig that way and if I need to do something with it I use Team Viewer from my phone or laptop.

Mainboard Bios -> advanced settings -> disable render stand by.

Let me know if that works ... Might give that a shot this weekend, if I have time.

System does not crash or anything it carries on mining, but the problem is that if I need to restart the system remotely whilst I'm connected through TeamViewer system does not load up without a monitor plugged in.

Will try this out once I get back home from work. Thank you.

Have you switched it to use onboard graphics as primary display device in the bios?

I did that last weekend on my vega rig and it wouldn't boot at all.  With or without monitor in the onboard hdmi.

I'm not sure which suggestion helped more as when I entered BIOS I have change switched on together. Now it boots perfectly from the first time. Thank you!

Good to hear.  I've tried the first suggestion on my vega 56 rig and it didn't work for me.  This weekend I'll look for the render standby setting .  I'm using a different board, so hopefully I actually have that setting.
