NVIDIA GeForce 6800 GT DDL and multiple monitors

I just installed the NVIDIA Geforce 6800 GT DDL and understood it could run 2 30" Apple monitors. I thought that was awesome. But I didn't have 2 30" Apple monitors. I just have a RasterOps Mc 8115 21" and I hooked it up to that and it ran great. So I dug out an old 15" PC VGA Monitor and hooked it up too.
Well the my big screen started the old roll and shake. Does the 21" RasterOps just draw too much to run 2 screens?

NVIDIA GeForce 6800 Ultra DDL supported for FC Studio II on DP PPC G5 2.5??

Up dated to 10.4.11 & Studio II (FC6.0.2) and no problem. Even launched Final cut once and all o.k.
2nd time, says grafix card, NVIDIA GeForce 6800 Ultra DDL isn't Quartz Extreme so, good by we're
quitting.
Swapped into another identical G5 and in Sys Profiler, says the card is Quartz Extreme supported.
What gives? I tried the Nvidia web site for drivers, but they show no Mac support.
Ideas?
thanks

Any progress on this? I just ran into the same problem. I launch Final Cut Pro 6.0.3 and I get an error:
1)Final Cut Pro requires that your system have a Quartz Extreme capable video card.
2)Final Cut Pro recommends that your system have 64 MB of VRAM; this system has only 0 MB of VRAM.
3)The installed graphics card does not not support the OpenGL features recommended by Final Cut Pro.
System profilor shows the GeForce 6600, but no Quarts infomration.

Duel 30" hook up to G5 with GeForce 6800 GT DDL

Well I have a G5 with 2.5 GHz with a NVIDIA GeForce 6800 GT DLL. I already have one 30" cinema display and I'm thinking about purchasing another one. But since the G5 is out dated and I can't find anything on the apple site saying if my graphics card would support two 30"s. Anyone have a clue?
And for if I'm not able to support the two monitors with my current graphics card, is it possible to update the card to either the NVIDIA Quadro FX 4500 or a ATI Radeon X1900 XT?

The NVIDIA GeForce 6800 GT DDL has two dual-link DVI ports, so can run two 30" displays at full resolution.

NVidia GeForce 6800 Ultra just died - need equivalent for my G5 - HELP

Hi,
I reviewed the posts but didn't find a simple answer to my mundane (if critical to me!) question:
I have a G5 as outlined below. I upgraded it the very day the 30"monitors were announced and received the:
nVidia GeForce 6800 Ultra DDL Card kit
My card died this morning and I need to replace it with a functional equivalent, I know the 6800 is rare which is fine- I just need whatever is available today to get fixed up.
Does anyone know what card I can easily get to do the job?
Thanks so much.

Alot depends on whether you ever have a second monitor hooked up.
There is a better, faster card than a 6800 for G5s called a 7800GS, but it only has 1 @ DVI port, and one VGA port. The DVI port can run a 30" just fine however. (Means it supports "Dual Link") These are all flashed PC cards....but the ROM is quite stable and they are GREAT cards.
If you need to run 2 @ 30" DVI monitors than you will need to find a Mac 6800 on EBay. It HAS to be an original Mac one, the "flashed" PC ones NEVER have Dual Link capability.
Another option would be a Max X800 XT...it has a DVI port good for a 30" and an ADC port which is only useful for an older Mac ADC monitor...but it can be converted to DVI with a relatively cheap adapter. These cards are super rare but occasionaly show up on Ebay. There are flashed X800s but most are VGA only...the DUal Link DVI ones are ULTRA rare.
No Radeon 9800 ever had Dual Link, so don't waste any time looking at those.
There is a retail option though I am not certain they are available anymore...the Radeon 9600 Mac and PC edition....has to be that one as most Mac 9600s didn't run Dual Link. These cards worked in Mac or PC and had 256 Megs of RAM. Sadly, they are MUCH slower than a 6800.
I can't stress enough that you need to find a card with Dual Link capability to run a 30". Otherwise you will end up looking at your 30" at 1280x800 instead of 2560x1600.
Try BruinMacs on Ebay, college kid who helped write the 7800GS ROM, now selling them for less than everyone else. He sometimes even has the X800 with Dual Link too, ask him.
Sadly, you will find that the official Mac 6800 and X800 cards still fetch $400 or so...the old "Supply & Demand" rule being hard to avoid. If you can find one on a local Craigslist ad, grab it up !!! (after testing)

Problem with MSI Nvidia GeForce 6800 LE (128MB) when playing 3D games

Games problem
I have bought a new MSI Nvidia GeForce 6800 LE (128MB) a couple of months ago and have been have loads of trouble when playing games.
In windows, the graphics card works fine. The computer never crashes and everything is speedy. Movies on DVD, Xvid, Divx all play fine without problem, the most I get is the occasional freezing and then windows will be normal again.
The problem arises when I try to play a 3D game. When I load up the game it goes into the menu screens ok, the computer will load up the 3D engine and it will play for around a minute nice and crisp then the screen will go blank and computer will lock up. Then all the drives will go quiet and the computer will make 3 beeps with the PC speaker. Pressing CTRL+ALT+DEL at this point does nothing, nor does the reset button. I have to turn the power on and off.
I really have no clue why this is happening, I have taken the covers off and kept it in a cool area, hoping that it was something to do with over heating, my computer is not overly cluttered and this has made no difference.
I have also unplugged the CDR, DVDR, USB ports, one Hard drive (storage) to see if it was something to do with the power no getting to the Videocard and then tried to play a game and the same problem arose.
I have two games that I have tried, Tiger woods 2005 and doom III, both of which crash in the same manner.
I have tried to be as detailed as I can with the descritopn of my computer below and the power details I'm not sure about so I posted a picture of the power unit to help.
Many thanks for your help in this matter, I'm desperately trying to get some worth out of this card and feel frustrated that its going bonkers only when trying to play games :/
Please tell me if you require further information about the system.

Firstly, thank you for all your prompt responses, I really appreciate it. From the sounds of it, the PSU is ****
antec
From what I have read, the Antec PSUs have good reliability and ratings. I looked around and saw this one: Antec NEOPower 480W ATX PSU for around £65. I also went read that article posted by Dr Stu, which then stumbled on more articles about PSUs.
I have a couple more questions….
The rating of my system (http://www.jscustompcs.com/power_supply/Power_Supply_Calculator.php) with all the components running came out to be 422W. So do you think that the Antec NEOPower 480W ATX PSU would be sufficient for the computer considering I might add more RAM in the future?
Or should I buy the 500W+ one then?
Does anyone know if the Antec PSUs are quiet? My current q-Tec one makes me feel I'm in an aeroplane.
lucky I read the forum!
I was in Maplins (computer shop) at lunch and thought, that shiny 650W Q-Tec looks nice and there looks like loads of power, that much do the trick. i got to the counter and thought.....let me wait, till i get home from work and read some more on the forum about this PSU issue.
Thanks god I didn’t buy that S***. having read some of the reviews, i would have wasted loooots of money for nothing.

Colour Issues - NVIDIA GeForce 6800 Ultra in G5 2.5Ghz

Hi
I have an odd issue with NVIDIA GeForce 6800 Ultra card in a G5 Tower.
The monitor (tried several screen so ruled that out) displays as if it is only producing Thousands instead of Millions of colours, but this is only seen at the Black end of the scale and white. For example, if you are viewing a folder's content as list, you can't see the pale blue lines under every other file. If you open another window on top, you can see the blue lines in what would be the shadow of the top window. So pale colours and dark colours are showing as white or black.
Interestingly I have a fix for this issue but it's not permanent as it reverts on restart. If I go to System Prefs > Displays and rotate the display 180˚ and then revert to 0˚ the problem is fixed!
I've tried everything I know to find a permanent fix :-
Dumping Preferences
Calibrating
Resolutions and Refresh rate
I did have this issue on an ATI card, but I resolved that with an ATI System Preference Pane.
Can anybody suggest trying anything?
thanks
Matt

Genius, this strikes a chord. I remember resolving this issue for a customer a couple of years ago and this was the answer. Was v.pleased with myself at the time, but obviously my memory is failing me now.
Can't test until monday, but will be in touch.
PS what does this say/mean - Aha, good clue, the bloe bard!
thanks
Matt

Graphics card for PM G5 AGP-ATI Radeon 800 vs Nvidia Geforce 6800

Any comments as to which of the two cards ATI Radeon 800 vs Nvidia Geforce 6800 is better suited for Photoshop-Aperture work?
I need to upgrade from a Nvidia 5200 that does not support Aperture and want to support at least one 30" + one 23" Apple cinema displays.
My PM is an AGP one, so these are the two high end contenders on the retail market.

I have the 6800GT, which works fairly well for me. I think the X800 is overall a slightly faster card, depending on what is benchmarked. Here is something you might want to look at:
http://www.barefeats.com/radx800.html
I don't know if you should pay more attention to the gaming benchmarks or the Motion rendering benchmark. I haven't seen any Aperture tests of these products. But I imagine if I was upgrading I would probably go for the X800. One thing I like about the 6800GT is it supports two 30 inch monitors. Unfortunately it takes up 2 slots. I have a pair of SATA cards in my Dual 2.5, so there go all my slots.

Nvidia GeForce 6800 Ultra / G5 Dual Processor / 30 in. Display

Just installed Nvidia GeForce 6800 Ultra in G5 Dual Processor and my 30 in. monitor is not working. Tried theis with my other monitor, a ViewSonic 8P810 and it didn't work either and said monitor had no signal. How do I know if card is working? I did hear the Mac ding letting me know the computer was powering up but not sure it finished. Will the 6800 with other cards above it? How often are these cards dead? Thanks, CD

Hi, I think you have to adjust your firmware, I just read this and it may help you.

Read through it, I didnt understand most of it but there are some usefull looking forum links that may help you.
Good luck.

Will this card work? - Nvidia Geforce 6800 ULTRA 256MB VRAM AGP Video Card

I posted a question about getting the maximum resolution from an Apple 30 inch Cinema Display and another card, which didn't work.
The replies were fast here in the forum and quite correct.
My next question is regarding the Nvidia Geforce 6800 ULTRA 256MB VRAM AGP Video Card.
I have an AGP card with an ATi Radeon 9600 Pro card that can't power the 30 inch because it's only 64MB and no DVI output.
I'm wondering whether this card will give me the maximum resolution?
Thanks again.

Hi Japamac-
Thanks for the quick reply.
My System Profiler indicates a ATI Radeon 9600 Pro, but it doesn't have the Dual Link since this is an older G5 with only 64MB of VRAM.
The GeForce 6800 is a refurb, but is Mac compatible.
I'm hoping that it will work, but since it won't be returnable, I don't want to spend the money needlessly.
I did order another card that the Apple support suggested should be compatible, but turned out that they sent me the PC version.
I've spoken to Apple as well and get conflicting info.
It boils down to the fact that this is a G5 with a late 2004 date.
It is fast enough for me and my only hang up is that I'm only getting 12980X800 resolution.
I'm not using it for gaming or graphics processing.
HTH.

[SOLVED] xcompmgr and nvidia geforce 6800 LE

Hello everybody,
I am installing arch on my main desktop on which I have a nvidia 6800 LE. I used wiki and almost everything works fine. However I am used to have xcompmgr running with awesome wm. But my xorg configuration for my geforce 6800 LE should be not correct because it's not working at all.
I observed that both modules freetype and type1 that are highlighted in wiki are not found on my computer ...
You can find my xorg here :

Windows 7 and Multiple Monitor Issues

Alright, I have spent the past 3 days searching these forums as well as on Microsoft's support pages and all of Google to find the answer to my issue and it seems as though I'm the only one who is running into this problem.
I have a 15 inch Macbook Pro with the GeForce 9600M GT Nvidia Graphics card with the latest version of Mac OSX and Bootcamp installed on it. I have Windows 7 installed in bootcamp. I just purchased a Mini DisplayPort to VGA cord with a VGA cord so as to connect my computer to my Sony Bravia HDTV to use as a second monitor. I plug in the cords, plug them into my TV, and put it into the proper input and it works like a charm. Then I go and boot up in bootcamp under Windows 7, plug in the cord, and my screen gets to the "starting windows" logo and then it goes black. I push ever button, I try control alt delete, nothing. I have to hold down the power button to turn off the computer and then turn it back on.
I turn it on, boot up into Windows 7, let it load, then plug in the cord, and the computer display instantly goes black, again, and yet nothing displays on the TV. Again, I try everything to no avail, so I power it off and back on. I go through this at least 10 times to no avail. I finally give up and try again the next day.
Next day, I plug it in, and the monitor stays up, but yet nothing is displayed on the TV. I go to my resolution settings in Windows, and go to the multiple monitors tab, and select every possible option (extend, duplicate, etc) and nothing will display on my TV. I try to change the settings to which it responds with "unable to save display settings" and nothing changes. I attempt to enter the nvidia program and make changes that way. The TV is detected, but when I select it and attempt to apply anything, no changes take effect and I am left with only the laptop display. Keep in mind I uninstalled and reinstalled all of the video drivers and such.
Finally I get fed up so I purchase a Mini DisplayPort to DVI adapted and a DVI to HDMI adapter. I try again. Again in OSX it launches immediately, no problems. I go back into Windows, and immediately I'm dealing with the instant black screen.
I'm going crazy over here trying to figure this out. I know it's possible to do this because I've seen people on youtube doing this and again it works on OSX so why the heck won't it work? If anyone has any idea what's going on here please help me out. Thanks.

JonMarx... I'm having the exact same problem. I'm in the exact same situation as you are. I'm going mad, and it's only by divine providence that I've finally located the only other person who knows what I've been going through. I've spent at least 20 hours trying to get this started back up, to no avail.
I had the secondary display working peachy for a while, long enough to configure everything to be exactly how I wanted it. I unplugged the monitor from the computer just to see what would happen, and that's when the problems started. I managed to get it to work one last time for a brief period a few hours later, but the way it just clicked on made it feel too good to be true.
I've had a wierd problem with a phantom display as well. The display will frequently show up as being available in both the nVIDIA panel and the windows settings, but if I apply the settings, they won't go through. I got a few screenshots of it the last time it happened.
I was just about to reinstall windows completely, but it seems that I'll just run into the same problem again if I do... Here's to hoping a solution is found.

Mac Pro and multiple monitors

I have a new Mac Pro (Late 2013) even though I bought it new in 2015. I have three monitors I'm trying to run on it.
2 are older Apple Cinema HD Displays.
Display Type: LCD
Resolution: 1680 x 1050
Pixel Depth: 32-Bit Color (ARGB8888)
1 is a Wacom 21UX which is my main monitor
Resolution: 1600 x 1200 @ 60 Hz
Pixel Depth: 32-Bit Color (ARGB8888)
All three hook up via Mini DisplayPort to DVI adapter ($30 a pop). I was under the impression that you could run up to 6 displays off this thing. This was one of the main reasons I upgraded and spent 4 grand on my Mac Pro. I've read in some other posts about Legacy stuff that the newer OS does not support this. I've also seen some post that talk about Active DVI adapters. I'm not sure what direction to go. It surprises me that this computer can't support multiple lesser monitors but will tackle 6 4K displays? Seems idiotic to expect an end user to only but that display at a grand each. There has to be a solution rather than going back operating systems to fix what will more than likely fail again. Thank gawd my brother gave me these monitors.
What Happens:
Only two will work at one time.

Hi,
This can't be true, I'm running 10.10.3 on a Mac Pro 3,1 (early 2008). This has 2 NVIDIA GeForce 8800 GT card installed in it with two monitors attached to each (4 in total).
I originally had 3 monitors each running at 1920 x 1200 @ 60 Hertz (NTSC), this worked fine. Today however I added a 4th monitor. The 3 original monitors are all Samsung 24A450's, the new one is an updated version of the same monitor - Samsung 24C450. When the monitor arrived, I shut down the Mac Pro, then attached the monitor and powered up again. When it started up, only two monitors were showing. After trying a couple of things, I shut down again and disconnected the new monitor and power up again, all 3 of the originals came back up. I then tried connecting the 4th Monitor (the 24C450) while the machine was still running and low and behold it recognised it! I configured it and it seems to work ok.
I have one remaining (minor) problem with it, the 3 original Monitors have resolutions of 1920 x 1200, but the newer monitor won't go above 1920 x 1080. Why is this? Is it possible to get this new monitor to match the 1920 x 1200 resolutions? If I got an active adaptor would this make it use the higher resolution. I'm connected via DVI on all four, is it a cabling issue? I am using the cable that came with the 4th monitor, but have another one on order which I'll try when it arrives.
So, unless you've solved the problem using active adaptors, you could try connecting the DVI to the machine while it is still running.
All the Best

Unable to save display settings and Multiple Monitors

Have Windows 7 RTM installed on my laptop and was working great with extending to my monitor. I took my laptop home and hooked it up to my tv and it was fine. Now when I bring it back to work I cannot get the monitor to work. Only the display on the laptop is working. Windows can detect the monitor, but I try to enable the monitor and when I select Apply I get an error message "Unable to save display settings". I am a local administrator on the laptop. How can I extend to my monitor!
Thanks

Hi,
Error message " Unable to save display settings" mainly indicates that you try to extend or duplicate the desktop to the two external monitors in addition to the laptop screen. Generally, laptop supports only two displays at one time due to hardware limitation. I
suspect that the issue occurs because the laptop remembers both configuration for your extended monitor and TV. To extend your monitor, you need to clear the multiple configuration for your laptop and then extend your display by changing your display
settings. To do this, please take the following steps:
Step 1. Delete registry key.
==================
1)Press Win + R to open a run box.
2)In the Run box, type regedit, and then click OK.
3)Locate the following registry subkey:
HKEY_CURRENT_USER\Software\Microsoft\MobilePC\TMM
4)Right-click the subkey that you located in step 2. Then, click Delete.
5)When you are prompted to confirm the delete operation, click Yes.
6)On the File menu, click Exit to exit Registry Editor.
7)Log off the computer. Then, log on to the computer.
Step 2. Extend your display by changing display settings.
====================================
1)Open Screen Resolution by clicking the Start button , clicking Control Panel, and then, under Appearance and Personalization, clicking Adjust screen resolution.
2)Click the drop-down list next to Multiple displays, click Extend these displays, and then click OK.

This registry key does not exist in my Laptop and it still won't work. I have an Asus N53S
which has both Intel HD Graphics 3000 and an NVidia GeForce GT 540M. It appears that the limitation is actually there is no D-Sub / HDMI / Internal Monitor option like there is in Windows Display.

Touchsmart and Multiple Monitors

Has anyone out there actually connected an HP Touchsmart to multiple monitors? I am aware that USB-to-DVI or USB-to-VGA adapters are required. However, I learned from one adapter manufacturer out there (StarTech) that there are known issues with these adapters and the Touchsmart. Has anyone had success? esp with synchronizing video? What brand/type of adapter did you use? My goal is to get one Touchsmart and 4 extra monitors working together. thanks

You shouldn't need to disable the "Touch" feature to enable "Extended Display" mode... however if don't disable it, you may have issues getting to the extended display or you may experience unpredictable results. Using a mouse should allow you to reach the alternate screen. Depending on your hardware, there may or may not be an option to disable "Touch (Use your finger as an input)" in the Windows Control Panel. You can, however, disable the touchsceen input device in the Windows Device Manager as shown below;

MAC G5 nVIDIA GeForce 6800 ULTRA power

just purchased a mac edition geforce 6800 ultra for my g5 dual agp.
will I need to power it by splitting the power from the dvd drive?
thanks

yes its a mac edition (with the little monitor graphic between the DVI ports).
So its powered by the agp port whereas a flashed card is not? just one more reason to stick with genuine mac i guess. thanx guys.
That's why I held out for the Mac edition card. Turns out that the ROM version on the one I got (2130, or 2.1.3) is later than some of the flashed cards. I paid a little more than what some flashed cards were going for and haven't regretted it for a second.
With two DVI-D Samsung monitors now, the viewing is just dandy now.
