From what I am seeing on the Invidia forums the only card that will support 3 monitor surround is the 590. Any other card in the 5 series will only support two monitors which would lend some insight as to why you can't get a resolution higher than 3840 across. Food for thought. Cheers Good point Dark. My understanding is that because I am running dual 560tis in SLI, that I can do three monitors across.  It could be that I am stuck with 3840 across, and if so, I can more than live with that. My plan is to buy two Dell 23 inch monitors, in place of the Insignia HDTVs, and will mix and match those with my Sony HDTV and my current Dell Ultrasharp monitor. If I can get something that works at 5760 X 1080, I will stick with that. Otherwise, one of the Dell monitors will go back and I will get back to sim racing. The 560tis in SLI will support 3 screens. Mine works fine. I have other issues getting rFactor to run. You did set screen resolution in both the Nvidia control panel & rFactor config right? They do not automatically adjust. |

You should be fine with dual cards in SLI unless there's some weirdness with your cards and their price point but I doubt that. 3 monitor SLI is a supported configuration.
I run dual GTX 275, a relatively old card, in SLI and it ran triples without issue the first time I connected them.

This has gotten the itch back to get into those damn dump files so I can figure out why the hell I'm crashing on rFactor startup. Going to try shutting down the antivirus program completely and try to set permissions on the folder. Maybe I'll have a little better luck. Last time I tried, it was telling me that another program was accessing the files...but naturally didn't bother saying which one...  |

What are your specs? Dual 560tis? What kind of monitors? |

If the two Dell 23 inch monitors do not work, I probably will end up buying two used Dell Ultrasharp monitors off of ebay. There are plenty of them listed. They are solid monitors, mine has worked great for 3 1/2 years. |

Ok after some research this morning I looked at the criteria to run Nvidia Surround and as was mentioned before your monitors need to have a common resolution, refresh rate and sync polarity. Now based on that I did some more hunting around and the culprit may be your sync polarity. The reason being that not all monitors will share the same sync polarity at the same resolution. So if you are mixing and matching displays the more likely you are to see an issue.
Surround may be showing you the 3840 resolution as a max because that is the highest resolution that is available where all your displays have their sync polarity as common.
The easiest way to test this would be to test using identical displays (brand model, etc) but your budget may not allow you to try that (unless you want to take advantage of Best Buy's no hassle return policy)
This is of course all theoretical as I don't have my own triple screen running yet and no way to do testing on my end for you.
Cheers!

Dual 560ti in SLi. 3 - 24" Dell monitors, 2 are identical (3rd is the prior gen of the same monitor). Wolf was thinking I may be having a driver issue (video or RAM), but I haven't been able to access the dump files to see what the hell the error is. |

Craig... If you still have problems with 3 PC monitors then try a total removal of Nvidia drivers (tutorials are all over the net) then a fresh driver install.

Craig... If you still have problems with 3 PC monitors then try a total removal of Nvidia drivers (tutorials are all over the net) then a fresh driver install. Thanks. Do you think a "clean install" of the driver via the Nvidia "Custom" install option is enough, or should I go deeper, for example, via Revo Uninstaller? I tried to do a clean install of the Nvidia driver on Sunday, but that did not resolve the problem. This is a real dilemna for me. I do not want to give up my 32 inch Sony HDTV. I love the extra real estate, and it works excellently for Forza and GT5, neither of which will be triple screen anytime soon. So, the best case scenario is that I can use the Sony HDTV as the center, my Dell Ultrasharp as the right monitor, and a new Dell 23 inch monitor as the left, with a max resolution of 5760 X 1080. If that doesn't work, I will consider using the Dell Ultrasharp as the center and two new Dell 23 inch monitors as the right and left. If that doesn't work, or if I don't like it and miss the Sony too much, then I can just go with the Sony as the center, Dell Ultrasharp as the right, and one of the new Dell 23 inch monitor's as the left and can live with 3824 X 1040 for iRacing and rFactor. |

I'd go as deep as you're comfortable (at least before spending any more money or boxing up the two HDTVs to return). There may be something to what Dark says but in this day I'd expect HDTVs and PC monitors to be using the same sync since DVI and HDMI are signal-compatible and used on a wide rance of hardware (the last monitors I can remember with different sync were some Sun workstation CRTs). And if the sync polarity didn't match I'd expect it simply to not work.
The reason I suggest a clean install is I've had issues with SLI Surround (one (and only one)of my cards was being forced to downclock in a power-savign mode during gaming) that cleared up after a reintall.

If you still have your manuals for the displays you can generally find the sync for the various resolutions in the back. That would help confirm or dispell the sync polarity question.
Cheers!

Cheers! Dark, thanks for this info. You have helped me avoid several more hours of frustration (and more trips to Best Buy). Armed with the info you gave me, I looked up the sync polarities for the Dell Ultrasharp monitor I want to continue using, and the Dell monitor I was contemplating purchasing. They probably do not match, since it looks like my Dell is +/- at 1920 X 1200, and the new Dell is +/+ at 1920 X 1080. The bottom line is that the hassle is not worth it. So, I am going to return the second Insignia HDTV that I bought yesterday. I will keep the other one and will reinstall it tonight. By doing this, the total dollar cost of Operation Triple Screen will be $80 ($180 for HDTV - $100 Best Buy gift card). I am not willing to sink more $$$ into this problem at this time. The worst case scenario is that I have triple screen gaming at 3840 X 1024. There are far worse things to live with in this life. That being said, I have several fresh ideas. First, I am going to try adjusting the sync polarities in the driver using the "custom resolution" option. Maybe it works, maybe it doesn't, but from what I have read, it will not damage the displays if I adjust the sync polarity. Second, I am going to try and set each display at 1600 X 1200, or other comparable resolutions, and see if that cause the sync polarities to match up and allows me to get a horizontal resolution above 5000 (ala F1Fan's set up). And finally, another solution is staring me in the face, particularly if I am at home in my office.  I have a seven month old desktop computer with an Asus AMD 6870 GPU, and Phenom quad core processor - I can try using that for iRacing and see if that allows me to do triple screen at 5760 X 1080 via Eyefinity. I have the cables to run each of my displays to it, although I have to check and see if I have a DisplayPort cable, I probably don't, so I might get one from Best Buy tonight just in case. There it is. That is my plan. Let me know if you have follow up thoughts, and thanks to each and every one of you for your comments and suggestions!!! You guys rock!!! |

Hm, it it is the sync polarities causing you problems then I've learned something from this thread. I thought it would either work or not work... I didn't know it would half-work.
I looked up the specs for my monitors and they're all -/+ at the native resolutions.

Sync polarities, at least in my Dell Ultrasharp monitor, and the Dell monitor I was contemplating buying, vary by resolution. For example, the attached link includes specs for my monitor, including sync polarity, and it does vary by resolution: support.dell.com/support/edocs/monitors/2408WFP/en/UG/about.htm |

For example, the attached link includes specs for my monitor, including sync polarity, and it does vary by resolution: Yeah I noticed that for my monitors too. That could well explain that weird-ass resolution you get in nvSurround. It's found the best combination that gives common sync polarities. By the way, that 2408WFP is an awesome monitor. Hang on to that. IPS panel and great image quality though some had uneven backlighting it's not that bad compared to how good the colour is. I hung onto mine at work as long as I could before they dragged it out of my office with me clutching the power cord. Then I got in a battle with IT to replace it with an IPS model from HP (our current monitor vendor of choice).  |

It could be that I am stuck with 3840 across, and if so, I can more than live with that. My plan is to buy two Dell 23 inch monitors, in place of the Insignia HDTVs, and will mix and match those with my Sony HDTV and my current Dell Ultrasharp monitor. If I can get something that works at 5760 X 1080, I will stick with that. Otherwise, one of the Dell monitors will go back and I will get back to sim racing.
