How to locate Cintiq 24 Pro inf file

Postby DocPit45 » Wed 22. Apr 2020, 18:06

I'm using a Cintiq 24 Pro on a Dell 7820 with Windows 10. In System>Device Manager>Monitors, the Cintiq appears as a generic PnP monitor. I do have updated Nvidia Quadro drivers and the latest Cintiq driver installed (WacomTablet_6.3.38-2.exe). To manually update the driver through Control Panel, I need to know where the .inf file is. I've searched for wacom*.inf or just *.inf, looking for the most recent .inf file after running the driver executable. All I find is an oem54.inf file, which I doubt is the Cintiq file. Can anyone tell me whether there is, in fact, an .inf file? If so, where does Windows 10 keep it? Or is there some other way to get Windows to explicitly recognize the Cintiq? My concern is that if Windows sees the Cintiq only as a generic, I won't be able to calibrate it correctly using the Wacom/X-Rite solution. Any help would be much appreciated.

Hi mind if I ask which connection are you using?
The the EDID info is transmitted through the video connection and if you OS is not picking this up it there could be a problem with the connection.
When you open the Wacom Display Settings do you see an error message?

To clarify, which driver are you trying to install through control panel and which process are you following?

Thanks for your reply. I'm using the DP connection. The WacomTablet_6.3.38-2.exe driver installed correctly. The Cintiq shows up in the Wacom Desktop Manager. I can access and program the tablet through Wacom Tablet Properties. No error messages. It all works fine. The only problem is that System>Device Manager>Monitors show the Cintiq as a Generic PnP. I don't know whether that will be a problem when I try to calibrate the Cintiq using the Wacom/X-Rite software. My fear is that it might simply produce a software calibration through the GPU instead of through the Cintiq's LUT.

I had the same problem with one of my two Dell monitors. When it showed up as a Generic PnP, I selected Generic PnP Monitor>Update Driver>Browse my computer for driver software, and I navigated to C:\Dell\Drivers\KJT8D, where the monitor's .inf file was located. Windows updated the monitor from that .inf file, and the monitor showed as U2720Q instead of Generic PnP. I'm trying to do the same for the Cintiq.

On the Wacom website, the WacomTablet_6.3.38-2.exe driver data sheet identifies the driver as wacomrouterfilter.inf. I can find C:\Windows\System32\DriverStore\FileRepository\wacomrouterfilter.inf_amd64_32c21c77aabb8f69\wacomrouterfilter.inf, however, when I try to update from that file, I get a message: "the folder you specified doesn't contain a compatible software driver for your device. If the folder contains a driver make sure it is designed to work with Windows for x64-based systems." A search in File Explorer does not reveal any other instance of that .inf file.

So, I'm stuck.

Thank you for the details. I am not familiar with this resolution method but I have seen issue before.
Mind that the Wacom driver only manages the Pen and other input data transmitted trough USB. It will have absolutely no influence of the video signal.
The only Wacom software that manages the video is the Wacom Display Settings which is installed with the driver.

Can you please confirm if you get an error message when opening the Wacom Display Settings? If you are able to open this then you don't need to worry. If you see an error message and the software states no Wacom Display found then this can be an issue for the calibration.
Can you also test with HDMI?
