Why does my Toshiba not register my Cintiq 22HD's monitor?


I've recently gottan my hands on a Cintiq 22HD pen display. I've installed it on my Toshiba Satellite C655, however, even with the use of a DVI to VGA adapter, the computer does not register a monitor.
I've tried it on a different laptop and it recognized that there was an external monitor, so it shouldn't be the adapter.
Driver are something I have also looked into.

Any help on what the problem may be? The tablet aspect works fine, but the computer acts as if there was no monitor, or really anything, plugged into the VGA port.

TL;DR - Laptop doesn't register Cintiq 22HD's monitor.

Thanks in advance.

I can come close

I have a 1 year Toshiba Satellite L755 that I've connected to my TV using both VGA and HDMI cables, and they work fine. That's the closest to having a match to your configuration I can come. I haven't tried it with an actual monitor, but both ports work fine with the LG 47SL90 TV. Have you checked your Device Manager to be sure you don't need a driver? That would be the first place I'd check.

Good luck.

The problem of a DVI output is

It could be the digital only DVI. There are 5 types of DVI so can you tell me which you have?

DVI Connection

Yes, the Cintiq 22HD has a USB connection (for tablet functionality) and DVI-I connection for the monitor itself.

Sorry you wrote "DVI to VGA"

And now it appears you meant the opposite. You'll need to check if your display can use VGA signals. DVI can be all digital. has a few manuals but the links didn't work.

Since it's not working that tells us it's either the old digital DVI issue, you didn't enable the output or the display is dead.

Since it's a new device, you need to have it's seller or maker do what they do best. Support.

I'd love to look into the DVI more but if the maker can't get a PDF link to work, I'm done.
