Windows 7: Cintiq 21UX (DVI) on 8800GTS - VGA signal only

12 Feb 2009   #1

Windows 7 Public Beta 64bit
Cintiq 21UX (DVI) on 8800GTS - VGA signal only

Should this be simply a symptom of beta drivers, I'll be cool with that. But I'd like to check if this issue seems similar to anybody else's who is running a comparable flatpanel on a similar videocard and only getting an analog signal.

It wouldn't be that big of a deal if not for the fact that the Cintiq on an analog signal has the swimming, scanning refresh shadows trailing up the screen. Bit of a headache-inducer and a blemish on an otherwise fantastic OS experience.

Monitor driver started off at "Generic PnP Monitor". Changing to "Digital Flat Panel (1600x1200 60Hz)" produces no difference aside from an interesting intermittent loss of video on some display power downs/ups.

Update 1:
Ok, trying out Digital Flat Panel driver again. Power/no-display problem seems calm. And there's less (nearly none) of the refresh flutter, yet the Cintiq still reports the signal as VGA and not DVI.

It's acceptable for now.

windows 7 rc 7100

i'm having the same problem on my gtx 280. the cintiq 21ux resolution is soft (analog). i've changed it to the digital display driver and the refresh was fixed, but no luck on the sharpness.

any help would be great.

Windows 7
Release Candidate

I just received the final version of the OS and I updated my drivers from nVidia (for the same 280 card) as well as the latest Wacom driver and it's still analog output. Any word on this please?

btw how can you tell it's analog other than just looking at it. I notice its analog because the display is not as sharp visually is there a setting somewhere I can view?

Windows 7 ultimate 64 bit / XP Home sp3

Is everybody using a dvi out to dvi in cable? Because if your using the VGA cable your only going to get analog. I know this is kind of a hey duh question but it is also a need to know. To the OP thanks for filling out your system specs in your user cp as this can be quite helpful with if any future issues. Everybody else please do the same. And welcome to you all to seven forums. (Added) I don't know if this tutorial will help but here it is Force DVI/HDMI resolutions and refresh rates

Windows 7

I will fill out my system specs in a moment but yes I am using a dvi cable without converters or anything of that nature.

I was getting perfectly crisp DVI digital output in XP 64 but I had to try some different versions of the nVidia software before I found a driver that the Cintiq would play nice with.

Windows 7


After much back and forth with nVidia (that ended with them suggesting this was a hardware issue and leaving me to call the manufacturer of the card ). I've discovered that it is INDEED a problem with the nVidia software. I'm not sure at what level this error occurs but there is something about the GTX280 (and probably other chipsets) not playing nice with the Cintiq 21UX. Maybe it's the capability of the Cintiq to output either VGA or Digital signals (there's a switch on the monitor) and the software just doesn't support it. I don't know. What I DO KNOW is that after trying like 4 different nVidia driver packages nothing was working, the only time I received a digital signal was when I rebooted in safe mode. Finally, I went to see if the working driver package I had on XPx64 had a Windows 7 64 bit version... it didn't. BUT there was a 64 bit Vista version for that driver package (it's 178.24 btw). So I figured I had nothing to lose, did a driver sweeper clean and installed the old package and BOOM, everything works perfectly. Full screen games at less than native resolution were no longer scaling down to a small window with a black BG. the signal was crisp and digital, and everything seems to work great!

The main problem I have now is that these drivers are relatively outdated so I'm losing out on the "30-40% performance gain" that nVidia cites in their release notes for newer drivers. I would love it if windows, wacom, and nVidia were able to identify the critical difference between 178.24 and more recent drivers so that those of us on Cintiqs could get the latest drivers to play nice with our monitor.

I hope this post is helpful because I've been scouring for a solution to this problem for a LOOONG time.

To recap here's what I did to get everything running perfectly:

1.) Download the working nVidia software from here: (64-bit) (32-bit)

2.) Reboot in safe mode
2.) Go to Device Manager and uninstall the display adapter for your vid card
3.) Run driver sweeper to clean out "nVidia display"
4.) Reboot in safe mode
5.) install the driver software
6.) reboot
7.) send me an e-mail thanking me profusely for spending hours every day tracking down the working drivers despite little or no help from nVidia

Best, Tim

blegh... I also have this problem. I guess I'll use some old ass drivers.. That sucks though. Did you call them on the phone? Cause I want to bitch their ear off too. I never understand why it seems like new drivers break more stuff than they fix.

I still find it annoying, but apparently if you use the DVI adapter that came with your cintiq it will run dvi mode. The adapter must strip out the VGA signal or something.

Windows 7 Professional 64Bit
Also having same problem

I have Windows 7 Professional 64 just installed (from XP64). All the NVidia Drivers (i have a quadro FX 4500) recognize my Cintiq as a VGA connection even when it is in as a DVI. Have changed the monitor type to digital flat panel, and have been unable to locate older drivers for the system that will work.

has anyone found a solution, pretty hard on the eyes as it is...

Windows 7

Now that my drivers are so out of date I am really struggling to run a lot of recently released software, there are bugs turning up with the old driver software but I can't upgrade because the VGA issue. It'd be great if Nvidia and MS would finally address this! I've contacted MS, Wacom, and Nvidia and they all just want to pass the buck
