After reading your Trading PC FAQ I recently purchased a Dell 490 and two NVS 295 cards. Currently I have two Dell P2214H 22" monitors connected via DisplayPort Cables and all is great. I have one additional smaller Dell 1707FPt 17" Monitor I would like to use as well (connected via DisplayPort to DVI Adapter). I have the Windows Enterprise 8.1 installed on a newer 500GB HD with 16GB of RAM, everything checks out on the 490 hardware / driver wise. When I installed 8.1 all three displays were on and working fine. This morning when I woke up the machine only the two Dell DisplayPort monitors were working. The 3rd Dell 17" will not turn on. I have removed the other Monitors and only have the 17" attached and when I restart I will see the initial Dell screen, but nothing past the initial Windows logo. I did notice that the Nvidia Control Panel installed itself, but now that I have re-installed Windows 8.1 this morning I cannot get the three monitors back... I have tested both cards separately with the 22" monitors connected via DisplayPort and they work great on either card. Could there be a potential conflict with the DP and DVI connected at the same time? Should I try a DP to VGA Adapter? I have a large supply of the 17" monitors, so I would like to use them instead of purchasing new DP capable monitors if possible. Any help would be appreciated as I cannot find anyone with my exact issue in google searches or here on ET, unless I have missed it for some reason in the search results. Thanks!
I couldn't edit this, but as an update I tried running one DisplayPort Monitor and one DVI-D to display port adapter Monitor and I cannot get the Non-DisplayPort Monitor to work...
I you haven't already... suggest you uninstall Nvidia card driver, connect all 3 monitors, and reinstall the Nvidia driver. Also... did you go into the Display function and select "Detect" with all 3 monitors connected?
Just tried it with the same results. I am wondering if it is the DVI adapter or the DisplayPort has an issue with DVI. I have tried various configurations with the cables and the cards with no success. I am going to start with changing to a DisplayPort to VGA adapter as the two additional square 17" monitors are only for additional charts I like to follow / track, not my main execution / charting windows. Thanks for the assistance, I will report back in a couple of hours.
Not sure what the issue is / was with DisplayPort to DVI when mixing with DisplayPort Monitors, but I picked up two DisplayPort to VGA adapters and now I have the Dell 490 w/ Dual 5160's, 16GB Ram, 500Gb HD, two Nvidia NVS 295's all working perfectly. Two Dell P2214H in the middle and two Dell 1707 FP's on the outsides for additional charts I like to follow. I had previously been using my laptop full time when I started looking for a desktop for a dedicated office machine. I spent less than $400 on ebay and Microcenter for it all. Thanks to WinstonTJ and Scataphagos for their thoughts on the forum and saving me a few bucks. Cheers!
Any component of the system, including cables or adapters, can be the source of a problem... that's why troubleshooting can be such a pain. I once had a display problem where I got Dell Tech Support involved and changed virtually every related component.... fussed with it for about 60 days. Come to find out, either Windows or the video cards didn't like a particular monitor being the "primary". Wish I'd have thought to check that first! (Strangely, that same monitor had been "primary" on another computer and worked just fine... but the new computer didin't like it at all. No specific indication in the BSOD, just "video problem".)
So true, especially when it is something that seems to be so simple. I have a running Evernote list of quirks I have discovered over the past ten years or so for just these issues.
