Hello folks,
I opened a question about this issue a while back but due to unforeseen circumstances I had to leave the country on very short notice and only got back recently.
The issue is that I've got three monitors connected to my HD6950, one via DVI, one via DVI-VGA, and one via Displayport-VGA.
The first two work fine all the time, no issues there. The third one (Displayport to DVI) works fine whilst the PC is booting and will work for a little while within Windows. It's very intermittent and if the PC goes into power saving mode there's a 20-25% chance that the monitor will "get a signal". I say that because the monitor itself shows that it's getting a signal - IE the power light stays on constantly whereas if they don't get a signal the power light flashes. The monitor however remains black. The backlight is on, the power light stays on permanently indicating a signal, but no picture.
I've tried moving between Displayports and I've tried swapping cables and adaptors around. These are brand new monitors (LG E2242 either side of an ASUS) and I've swapped them around to eliminate a monitor issue. Yesterday I stripped my PC completely and rebuilt if from the ground up double checking all the connections along the way.
This seems to be a very isolated problem as I can't find any info on this. I've updated drivers, Windows (7, 64bit) and made sure everything's up to date.
Some other thoughts, based on internet searching that might be relevant:
Active DVI-VGA adapter. This could potentially be the case but given that the monitor does receive a signal of sorts, I'm inclined to think that the adapter is fine.
GPU power saving mode - Apparently my GPU has a power saving mode that will turn off the displayports until there's a need for them, but again, the signal's there it's just showing a picture.
Another thing to take into account is that if I leave the speakers turned on, I'll hear the "hardware connected" and "hardware unplugged" sound at random intervals. This could happen every 5 seconds, it might not happen at all.
Everything so far is pointing at a faulty graphics card but I need to eliminate this for sure before I go spending a few hundred pounds on a new one, and if this is repairable with a BIOS flash then I'll look in to that too (the card has a dual bios for unlocking the extra shaders and both of them have this issue).
If anyone could shed some light on this I'd be very grateful as it's incredibly frustrating and no matter what I do, nothing seems to solve it.
Apologies for the long post but I wanted to get in as much info as possible. If there's anything else you'd like to know please don't hesitate to ask.
Thanks,
David
