Cintiq 12wx screen is blank

[ceetree]

The screen on my cintiq 12wx is blank all the time, and the light is on orange. When I turn it on, the light is blue for a little bit before a 'no sync' comes up, then it goes to sleep. I use Windows 7. My computer can pick up when I move the tablet pen over the tablet screen, and I can write with it. As far as I know it's nothing to do with any possible loose wires in the tablet, because my tablet works fine with my Vista laptop.
Previously I would try to duplicate the displays, which lead to my computer freezing up. After I downloaded the latest driver I tried duplicating the screens again, my computer didn't freeze, but the tablet screen is still blank. When I tried to detect other monitors the only ones my computer would pick up were the actual pc monitor and 'P205H', but since duplicating the displays that one has disappeared. Please help!

Graphic card or driver issues would be my guess.
What is your hardware set-up, what connectors are you using from your graphic card and which monitor is plugged into the primary connector?
If everything is attached correctly and assuming your tablet is your second monitor, have you got it turned on in your graphics application? I presume you have as you mention dual display, but I thought it best to check.

Post script: The P205H is an Acer monitor? Is it still attached or is it a long discarded display? Possibly the drivers of that are interfering if they haven't been uninstalled. Perhaps a complete uninstall and reinstall of everything display related might solve it.

Hi aardvark, what exactly do you mean by set-up? I'm using the VGA cable to connect the converter box to my computer. My tablet is on, and as far as graphic card connectors go, I'm really not sure.
I am using an Acer monitor, yeah, and it has P205H written on it, but in screen resolution menu, it says that it's a 'P205HL'.
When I duplicate the displays the second monitor it detects is an 'Acer G205H' but that should really be the Cintiq.. (On my Laptop it would always detected the second monitor, being the tablet, as a Cintiq 12wx)

I also uninstalled the drivers for both of the monitors. I did no.1 first (my acer monitor) but on uninstalling the driver for the second monitor, my screen resolution was really messed up, and I couldn't get it back to how it was. So I kind of freaked out and did a system restore.

Thanks for your input, and I apologise for not being able to answer your questions fully. This subject matter is confusing to me.

I was referring to your computer in terms of CPU, memory, operating sytem and graphics card, just to get some background. There is an outside chance a lack of resources could be to blame.

As your graphics card has dual connectors (I would guess one VGA and one DVI, but there are many variations) then it might have some form of software interface/utility that you can run on your computer. These often have 'wizards' to help set up a second screen.
Of course, the simplest access is right clicking on your desktop, choosing properties and then settings.
As long as the two graphics of monitors look the same and not greyed out it would indicate that the signal is being fed to the card (do click on 'Identify' to make sure you get the correct large number on your working monitor). If this is the case, you need to verify your card is working properly by attaching another monitor instead of your Cintiq.
If you get no response from that then there are three main possibilities in this order of likelihood:
1. There is a driver conflict
2. Your graphic card is broken
3. Your power supply isn't up to the job (graphic cards can be very power hungry and you can get odd effects if you haven't got sufficient power).

Unfortunately, it can be very hard to determine which, although it does look like something is not right if it is detecting your Cintiq as an Acer!

To help with your previous panic, the resolution will always go back to a very basic level when you uninstall all drivers, but no data is affected. Once you install the correct drivers then you can reselect your preferred settings.

I would restart in safe mode and remove all display drivers (check in device management to see if there aren't some hidden ones) and then only install the proper ones after rebooting. You may, of course, have to download the latest ones for all your kit (graphic card, monitor and Cintiq) before you start.

There is not much to add for me. - The Cintiq should be detected and Plug and Play monitor or as Cintiq12. If that does not happen and your machines detects an Acer monitor instead, I guess something is messed up in the graphics driver. Uninstall the graphics driver, restart (it will use only low resolution VGA), then install the latest graphics driver for the card. You should alos check the connection cables - sometimes a pin is bend and does not make contact, sometimes a wires in the cable has loose contact when the cable is twisted. Also check the DVI/VGA switch on the box.

The funny thing is, my laptop screen is blank instead. I'm using a Hp pavilion.

Most laptops have a switch to change the display.
Did you already try if changing the active display with this button helps?

[Mossyhairundys]

Yup. But the choice to duplicate, clone etc is gone, leaving my Cintiq as the main display. There is nothing wrong with my graphic card.

Before you could use it in clone mode, but now the option is gone ? The Laptop screen works ok, if the Cintiq is not connected ? It could be a problem with the graphics driver or its settings, so it could help to uninstall/reinstall the graphics driver.

[Mossyhairundys]

There's nothing wrong with the graphic driver. Even when I want to turn on my laptop normally without the Cintiq, the screen remains black and if it's with the Cintiq, the Cintiq is automatically set as the display. I'm afraid that if I try and uninstall my Cintiq, my laptop might not be able to work anymore as the screen might remain black. As the Cintiq would have to be the main display.
