HD6870x2, no picture when multiple monitors connected from a cold boot

post #1 of 12
Thread Starter 
Ok, so I have a HD6870x2 and when I have one monitor connected to the DVI out below the DP connectors it boots fine, I get a picture, etc. no problems. However, if I connect a monitor to each DVI connector and one to either DP or even one in each DVI connections, I get no picture during boot or in W7. I can connect just one monitor, then once into W7, connect the other two, no issues and then as long as I am only doing a restart everything works fine, it only happens from a complete reboot, meaning I shut the computer off and then power it back on, no picture with multiple monitors. I didn't have this issue with either my dual GTX480's or HD6990's when I had them. Not sure what I am missing, so any suggestions would be great. I am going to try just a single HD6870 and see if it's the GPU, but I am not what is going on with the HD6870x2.

6870 has two DVIs, one if DVI-I (capable of Digital and Analog) and the other is DVI-D Digital only. So if both your monitors are DVI-A Analog you can only use the DVI-I. The second monitor would need DP-to-DVI-A Single Link for 1920x1200 and Dual Link Active Adapter for res above 1920x1200 - 2560x1600.

All my monitors have DP connectors also. It's just weird and if I remember correctly I didn't have this issue with it installed with the OEM cooler. I am wondering if the GPU bios not seeing a fan connected is limiting the ports and basically shutting down even though the GPU is being kept cool. I am going to test my theory tomorrow by reattaching the fan and see if the issue is still there. It would be interesting if I have to flash the BIOS to get it to work properly under water.

One thing you can do. Remove all CCC drivers. Shutdown and swap the cards around for the mainboard BIOS to re-detect then install CCC package + CAP.

Well, connecting the fan back up didn't change anything. This is what I have tried so far:

Uninstall and reinstall of drivers.
Changed location to different PCIe lane
Changed MB - Same model.
Different power connectors.
Used a DP to DVI active dongle
Tried just one connection on the other DVI connector and just the DP connected.

None these changed the situation. From a complete boot I can only have the DVI connector under the DP connections connected to video on boot up. Once I am in W7 I can connect the other monitors and everything works, including doing a restart and the monitors come up during the boot process. The card is adequately cooled and powered. Kinda dumbfounded by this.

Please take a look at this DVI pic. One or two of the ports are sharing signal line inside the card, it might explain why. If you really want to make sure if what I am thinking is correct and to make sure DVI port is not defect, you can try to swap the secondary card as primary. If it gives the same result, it is a hardware limitation.

By the above bolded sentence, do you mean you connect the other monitors to the graphics card while the system is running, ie hot plugging the monitors in?

This sounds like a 'dangerous' practice to me.
This this (if you have not yet):-
a. all monitors are connected to the card
b. all are turned off except the one monitor connected to the DVI input directly under the DP inputs
c. turn on the computer and boot into W7
d. turn on the rest of the monitors

The general practice is to turn on all monitors before booting up. So, you simply postpone the turning on the other monitors until a little bit later.

If this procedure works, then it will also eliminate the 'dangerous' hot plugging and this might be a temporary fix until a permanent solution is found.

On a side note: make sure the adapters you use is the correct one. Powercolor might put the wrong adapter(s) in the package.

I see what you are saying, but then why would it work fine on a restart and not on a shut down and then boot up?

Never had an issue before with hot plugging monitors, but I will give it a try what you are saying just turning off the monitors and then seeing if it boots up with video.

Thanks for the help guys.

Please take a look at this AMD Eyefinity minimum requirement configuration #1. Since all your monitors have native DP and DVI, by right you need no active adapter. If both cards having similar issue, you might want to return or replace it with other model.

But check these for co-insurance to avoid dispute:

1. The card is advertised Eyefinity capable in published terms.
2. Your monitors are listed in AMD Eyefinity Compatible Display Panels
