Monitor problem or graphics card?

I hope someone can help me with a problem ai have with a Monitor. Until recently i had a PC with one Geforce 460 Gtx, on which I was running 2 Monitors. Both on DVI. One Benq 2450 as main Monitor and a HP 2229 as secondary. Was running fine. Now because of some other Hardware broke, i decided to get all new Hardware for the PC. The only remaining things were my Harddrives. Now i have a Geforce 770 gtx from Zotac. After putting it all together and using the same Monitor situation, I noticed my main monitor to go black sometimes. Never the other. Because that Monitor, the Benq, had HDMI and my new graphics card as well, i tried attaching that one via HDMI. It worked for a bit, but it started again. The Monitor went black sometimes and just stayed that way. It only has a picture for a few seconds, if for example you restart the computer. For a few seconds it shows you the loadscreen of the Bios at the beginning when the monitor gets the first signal after starting the Computer. Same after loading and when the Windows logon Screen shows, but only for a few seconds, then it goes back to black. The other Monitor, the HP, works fine. On that I can only test DVI, not HDMI. Is that problem now a Monitor problem or that of the graphics card? But if it would be a problem with the graphics card, why would it only happen with the Benq Monitor and not with the HP? Or is there a general problem with 2 graphics adapters on the Gtx 770 Series? I am using the latest Nvidia driver that was released, however since I just updated to that driver today (had the previous 331.xx driver installed before) could it be a driver issue? If anyone knows what it could be or what would be the likely issue, I appreciate any help with this. Need to make sure whats broken and if I have to return the graphics card or get a new monitor or what else.

 Thanks in advance

Try and make sure the resolution is set to an appropriate rate for the monitor in question.

It is, its not the resolution, that I know for sure. As it was on my previous PC. The Benq runs with 1920x1080 and the HP with 1680x1050. That was running before, and also with the new PC. And as I said, it was working. The black screen issue happend first time on the new Hardware and PC, not the previous. But again, if it is the graphics card, why would it only make that issue with this Monitor specifically, either plugged in via HDMI or DVI. Unless its an issue that the card of that series would have issues with 2 monitors at all.

I'm suggesting that the resolution may not be set properly (via the nvidia control panel) since you basically hooked the monitor up to a new computer and when the new cards drivers were install they did not set properly for the Benq. Also make sure the new drivers are configured to run a dual monitor setup.

I know what you're saying, Dom. :)  Its just that it worked before, even on the new PC, with all the right settings earlier today. But it doesnt anymore now, the monitor only shows a picture when he gets a new Signal. Which is first time after stsrting the computer, then it goes black while the PC goes to load Windows. And then when the Windows logon screen comes, the monitor shows the picture for a few seconds and goes black again.

Thats nothing to do with resolutions.

Cheers

Ah! Sorry I wasn't clear that you had got it working on the new rig. My bad! Kind of a long shot but check the sleep setting (if there is one) on the monitor? Can you check the Benq on another computer ? Because at this point I'm leaning towards the monitor having an issue.

Two "food for thought" things:
1. I've had a bad experience with a Zotac card in the past.
2. At least this discourse between us gets your question back to the top of the list in the forum and possibly one of the moderators or an expert will give it a look and have more/ better advice :)

Thanks, dom.

I will test the Benq tomorrow on my gf's PC and also try her Samsung as a replacement on mine to see if that works. However, I am curious what kinda bad experience you had with Zotac cards. And if, was that something known to be an issue with Zotac cards in general or was it just yours?

I got a card that worked inconsistently/oddly and had suspicious solder "splatter" on the board seeming to bridge connections. Eventually (after about a week of correspondence with Zotac and Newegg) I got a free return shipping and a complete refund and never heard anything more.
I haven't heard anyone else checking the physical condition of their Zotac cards that were faulty as thoroughly as I did so I don't know if that was the issue or even if it's a common issue.

Let everyone here (or at least me :)  ) know how things work out tomorrow!
Cheers!
P.S.: Try to convince your G.F to swap monitors with you (I hear Samsung's are pretty freakin' sweet and Benq's not so much ;)  - Just tell her it can be an early Christmas present LOL

Check your refresh rate too.

Also, maybe there is a short in the cord? Dust in ports?

Hope everything works out well.

Thanks guys, I will know tomorrow morning. 3 AM at night now, time to go to bed now. After paying over 1200,- Euro for my new Hardware, i really hope i dont have to get another new Monitor as well. A bit too much right now. If its the Benq, i will have to stay with my HP for a while, even though that can only 1680x1050. But better than nothing.

Glad to see so much help here, appreciate it.

Cheers

Unfortunately that issue comes with DVI and HDMI, so i doubt both have problems. The HDMI works fine at our PS3, so the cable I dont think is the issue.

Have you tried hooking up the PS3 to the Benq with the HDMI cable? If that works fine then the issue is with the card/ drivers/ setup(somewhere). Try that before hauling your monitor to your G.F.'s

The Benq worked via HDMI on the PS3.

Well, it is what I was afraid of. The graphics card seems to be the problem. The Card has 2 DVI outputs, but they are slightly different. One is DVI-I and has a few extra holes for pins, one is DVI-D with just the usual pin holes on one side, and a wider hole. And my Benq works with that DVI-I while the Samsung of my girlfriend is, like my HP 2229 working with a DVI-D.

So if it would be that the DVI-I output wouldn't work properly, then I wonder why the HDMI is also not working, at least with the combination Benq / HP. I will now try to also attach the Benq via HDMI while the Samsung is attached via DVI-D. If that doesn't work then maybe the card is defective as for using multiple Monitors. Which would suck.

Did you get the drivers installed?

It seems the weird things are not stopping. So, we know that the HDMI works with the Benq on the PS3,but not in combination with the HP (over DVI) on my PC. I tried the combination with the Benq and the Samsung Monitor of my gf on my PC, same problem. No matter if I put the Benq via HDMI or DVI. Picture for a second shows, then goes black. So now I tried the HP and my gf's Samsung on my PC, both via DVI (because both dont have HDMI), and that works on my PC.

So with that in mind, and being a bit sorry because i loved the Benq, i setup that via DVI on my gf's PC on her Geforce 460 Gtx, and guess what, same problem. Picture comes for a second ans goes black again.

So considering all that, although it looked initially as a problem with my Zotac graphics card, I'd say now it is the Benq or what do you guys think?

And yes, I also removed the graphics drivers on my PC before the last test on my PC with the Benq. And installed them fresh, after completely removing them.

But if all these issues now point to the Benq, why would the Benq work via HDMI on the PS3? I wish i would understand.

That is a very odd problem to be sure... The only thing that comes to my mind is that possibly the PS3 has a lower or more stable refresh rate than either PC. In the long run it looks like you may want to try for tech support from Benq on this as it is clearly their product which seems to have an issue.
