Asus A8N-SLI SLI Mode Dual Monitor Problem Help?

[michaeldorian]

Anyway guys finally got my quirks worked out regarding SLI. Got SLI enabled on using 2 EVGA 6800U, but now another problem arises. The problems never seems to stop with this dang board. I can't seem to get into Windows XP when I'm using dual monitors on the primary vid card with SLI. With both monitors plugged into each DVI port, the windows progress bar screen would load but just as its about to go into Windows everything freezes and a hard reboot is required. Unplug one monitor reboot and the system boots no problems. When I was running just a single 6800U, dual monitor worked flawless. Is this an isolated case? Has anyone else experience this problem? Any advice on getting this fixed? Anything is appreciated.

Current System Setup
ASUS A8N-SLI
Corsair 3200XL Pro Dual Channel DDR400
OCZ Powerstream 600
2x Raptor 74 GB Raid 0
2X Liteon Drives

Monitor Config.

Primary 6800U (Blue Slot)
Port 1 - Apple Cinema Display 23 DVI
Port 2 - Sony GDM-F520 - Analog VGA


Anything help would be awesome!

Hi:

I have the same trouble.

the Nvidia driver works different if you have a "analog connection - with the adapter" vs a DVI connection. Some tabs where turn "OFF" by Nvidia in the Nview DESKTOP MANAGER when you use the DVI connector and are not being supported until the release of the next set of drivers.

I have a Velocity Micro Raptor dual PCI-e with 6800 GT (2) and SLI "ON"

The machine will work fine if the monitor if I use an old dual monitor that has both DVI and "analog" connectors, even when connected to DVI.

If the monitor is pure digital, or one of the lattest model. The card will identify this and will use the Pure DVI driver subrutine. This has advance timming "off". As a result SLI only support high definition monitor at their native resolution (Apple Cine, HDTV -LCD, Plasma and some Viewsonic Monitors). Monitor with 1920x1200 or more. Changing to a lower resolution will turn the creen into garbaje. OUT OF SYNC.

Nvidia knows about this and have erase all connects in their SLI site. If you have a SLI and DVI monitor try turning SLI "OFF" in the driver (NVIDIA TAB) reboot and then try to turn it back "ON" you will not be able to. So be very careful. Then you will get the two monitor like is mentioned here. The only was to go back is using system restore.

Playing games in those pure digital monitors can not be done with actual driver for SLI, changing to a lower resolution (most games are 1024 or less) will result in a garbage screen. The ystem will work fine if SLI is turn "off" but the other card will be there for the ride.

The only solution is to use a LCD monitor with dual connectors (that has both connector "analog and digital" ) or a CRT

The idea of SLI was to run games at higher resolution but Nvidia put the system put before the drivers where ready.

NVIDIA has failed miserably with this release.....

SLI DOES NOT WORK WITH PURE DIGITAL DISPLAYS !!!!

SOYLEN GREEN IS PEOPLE !!!

NVIDIA STIFF US !!

If you unplug the Apple Cinema (pure digital) and connect the other monitor only it will work fine but you will be in a small screen....

If you can fix it let me know I love my Apple Cinema 23 and Nvidia is supposed to be a provider for Apple.

 

[michaeldorian]

Yeah what the hell is up with that. I love my Cinema Display for working on normal stuff. Does anyone know if this will get resolved anytime soon?

Anyone think this is a hardware or software error?

Nvida come-on.

Can you confirm from a source that SLI will not work with PURE DVI displays in dual monitor mode? I can get my cinema display to work just by changing the res to the normal res 1920 x 1200, but one reboot into windows it always goes back into its distorted mode and I would have to change the res back to1920 x 1200. It gets all messed up when I try to run Apple + Sony. What a waste of an extra monitor.

Are you able to run the Cinema Display just by itself? No Dual Mode? As in dual monitor with SLI enabled

 

[DrRios]

Yes I can run by itself, connected in the #1 connector in the upper card.

But only runs at native resolution 1920x 1200.

It work for internet, work procesor and application that do not change the native resolution.

It is not working for games.

Unplug both, plug the some to #1connector and reboot, change the sony to 1600 resolution (if it can), then turn off plug the Cinema, the screen will be mildly distorted (that is because is in 1600) change resolution to 1920 and now it looks well.

But you will not be able to play games and QUicken if you use it will be slow !!!

Damn, that sucks! I dont have 2 analog monitors to test, but were you able to get Dual Displays to work in SLI using 2 standard monitors? Not a full digital display? I just want to know if dual display will work in SLI and our is just an isolated case becuase of the cinema display. I hope this is fixed in the next driver release. What version forceware are you using?

 

[bkzshabbaz]

Im having a similar problem, I have a Dell 2001 FP 20" LCD and When i boot up in SLI mode, it goes past the windows load screen and after that, i get the message "Cannot display this mode" and the screen turns white, and i have to reset!...whats up with that??

 

[Chillburgh]

but were you able to get Dual Displays to work in sli using 2 standard monitors? Not a full digital display? I just want to know if dual display will work in sli and our is just an isolated case becuase of the cinema display.

This is exactly what Im trying to do right now.

I have 2x MSI 6600GT on an Asus A8N-SLI Deluxe and 2x 17" analog LCDs. SLI mode works great on one LCD but I cant get it to initialize / recognize the second display - Windows says "You have have noticed one of your displays go blank. This will only occur in SLI mode." The thing is, the nVidia FAQ states that it should be possible: http://nvidia.custhelp.com/cgi...X3NlYXJjaF90ZXh0PXNsaQ**&p_li=

I've tried driver versions 66.93, 71.24, and 71.40. I even flashed my mobo BIOS to 1003-008 and still no luck. I've tried using the monitors in various ports on the cards - it still only sees the one primary display. Total waste of money if I cant get this to work. Its retarded to have to reboot in order to get into SLI mode and then again to get back to a dual display setup.

It would be great if someone had the answer to this problem.

Yeah this would be a complete waste of money IMHO. At least you can get one display to work with both plugged in. In my case Ijust get a freeze and a tiny blue square in my second display. If I boot up in with one display and then plug in the second it wont detect the second display at all. They better have a fix for this ASAP. At least I know other people are having this same problem and its not isolated to me. If you guys find any concrete data about all this and how to resolve it keep us posted on this thread. Thanks! Dual monitor is just as important as SLI to me. Gotta make a decision.

 

[DrRios]

again SLI does not work with Pure Digital Monitor that are usually over 19 inches.

If your moniotr has only DVI connector there is a great possibility that you can only use this monitor in the native resolution.

the only Nvidia driver that support SLI are 66.93 or the BET 67.02 (I thinkt)

they have the advance timming feature turn "OFF"

I does not know why? But it is impossible to turn DMT or CVT "ON" as display default that is what most of this Pure Digital Monitors use.

I discover this for the last month and Velocity Micro and Nvidia have been ignoring my emails, because the customer service can not fix it.

At least they should post a warning in their web site.

Any lawyer here... Do I hear class action lawsuit !!!

 

[DrRios]

Some guy that has a 21 inch monitor with both analaog and DVI solve the issue this way.

For me in the Apple Cinema (only DVI) connector does not work but try it...



Michael
Dr Rios - you CAN salvage your high-res monitor - the NVIDA drivers are set to default at GMT monitor timing which will crash a DVI connected 1920x1200. Change it to CMT and it works fine. I had a hell of a time doing this, working through ASUS, Velocity Micro and Evga and had to figure it out myself.

He means DMT I think

 

[DrRios]

If it has a analog connector try using it with the adapter that the card brought, the analog subroutine of the drivers works very well.

start bugging NVIDIA and the computer maker so the issue will be fixed !!!

Is a driver issue...

 

[vidguru83]

i had my DVI connection go bad, and switched it to analog and it works now. definately a problem.

Any links to instructions on how to do this? Damn Nvidia no warning at all. I am assuming that even with we bought a pre built machine like Alienware's 7500 Series with SLI we would have the same problem? I am up to my neck in problems with my SLI rig and its driving me crazy. Class Action!

Michael

 

[DrRios]

Yes...

Mine is a NEW (less than 1 month) Velocity Micro Dual Raptor with SLI and 2 6800 GT PCI-E

Top of the line, well built machine, cheeper tha Alienware and same component (except water cooling, even when I think they are using the water cooled Sony system now), and they have been nice since I keep bugging them about this and they can not do anything since is a driver issue and NVIDIA is the responsable party.

Nvidia have removed all the posting in their support center and if you ask they give you the run around and send you to the vendor of the machine or the vendor of the card.

The guy told me he turn off the computer ; connected to the analog in the monitor with an analog cable and the adapter that the card has. When the machine reboot the nvidia analog driver nview came "on", then the advance timing tab works and you can change then there or a new tab apperas at the top that also allows you to change timmings.

he then shut down and plug back the DVI with DVI cable and worked.

I would try this but I can not work mostly because my monitor has no analog connector is DVI only.

I am also very frustated , I have a fast computer that I can use for work (thank good if not I will have return it even when it is NOT Velocity Micro's fault) and internet. email and other, but not for games..

Textis not

I'm in your same boat. I guess all we can do is wait.....

To comment on this part:

I just got off of the phone with MSI tech support (f-ing TERRIBLE to get a hold on, BTW) and they say that dual displays are NOT supported in SLI mode, as per nVidia specs. Again, this is in direct contrast to the nVidia FAQ which states that 2 displays are supported in SLI mode, but not 3 or more. See this post for the details.

So, MSI and nVidia are directly contradicting each other. This is always fun. It would be nice to get a conference call going.

 

[michaeldorian]

Okay,

This totally sucks. Thanks for the update Chillburgh. Atleast I know that it is a known problem. I hope they get a fix for this soon. Here's to hoping. How if I can get rid of my random reboots and get my audigy card running I can call it a case closed.

Nvidia needs to get its act together.

 

[michaeldorian]

Hi,

Has anyone tried this yet? Any taughts? Does this actually help anybody? Solve any stability problems? I dream of stability.


Beta Drivers - ForceWare

ForceWare Release 65
Version: 67.66
Release Date: January 18, 2005
BETA Driver


http://nzone.com/object/nzone_...ds_winxp_2k_67.66.html

Going to try it when I get home. I hope this addresses some things.

Michael

 

[DrRios]

I just got home

there is a new beta driver

is advise as Pure Digital

http://nzone.com/object/nzone_...ds_winxp_2k_67.66.html

Anyone with Apple Cinema dare to try to see if it working ??

 

[DrRios]

Sorry try the new beta driver 67.66, and then I could not turn SLI "ON" !!!!

 

[Chillburgh]

To comment on this part (again, for those of you who seem somewhat interested):

I dont have 2 analog monitors to test, but were you able to get Dual Displays to work in SLI using 2 standard monitors? Not a full digital display? I just want to know if dual display will work in SLI and our is just an isolated case becuase of the cinema display.

I called nVidia today (dont ask) and talked to a support guy who at least had somewhat of an answer for me. He said that dual monitors are currently not supported in SLI mode, but that a future driver version would support this. In the same sentence he said that the driver was probably 3 months out. I pressed a bit (read: whined) and he took my name and number and said that he was going to try to get more info and would call me back. I never got the call. Not surprised, really - was just hoping. I suggested that they update the FAQ on their website to reflect the current lack of support for this, since it currently claims that it is possible.

*sigh*

 

[SpeedDemonAaron]

I'm beyond pissed about this as well. It's not just dual displays..... you can't run SLI if you want to output to a digital display at all. When I connect my Sony 34" XBR HDTV up to my computer via DVI it doesn't work at all. When I try to enable SLI with the HDTV connected it says:

Your displays, which are attached to your secondary graphics card, will appear blank when SLI is enabled.

This is because your secondary graphics card will accelerate your primary card.

Connect your display to the primary graphics card when your system restarts.

Although, I already have the DVI connection running through my top 6600 GT. The second that I click OK to the message above though and hit apply the check box automatically unchecks itself. It actually let me check it when I had the computer connected via component video, but once I restart the computer it runs, but barely... extremely slow with garbled sounds. The only way I got it to work was with an analog 17" LCD that I dug up and connected to it temporarily.

If NVIDIA is only supporting analog displays that is just BULLSH1T!!! I just purchased the $2000 HDTV and the $600 MSI 6600 GT SLI + ASUS A8N-SLI Deluxe setup and it doesn't work. I'm so sick of advertised features not working. I wonder if NVIDIA wants to buy back my $2600 setup that I bought having so much faith in them. I have been a long time supporter of NVIDIA all the way back to my second 3D card which was my nVidia RIVA 128. I even bought a good chunk of their stock the day it opened for trading. It's a sad day when they have let me down this much. The only way I'm going to be happy at this point though is if NVIDIA can release at least a BETA driver that fixes this problem within the next couple weeks.

I consider it unacceptable for me to have to run just one of the 6600GT's in my system right now because the drivers won't support me running them in SLI with my display.

Please help NVIDIA!!!!!!!!!!!!!!
