So I just got in a Wacom Cintiq 12wx used on Ebay. Looks like whoever had it never used it.
I have everything plugged in and am using a Mini Display Port to DVI adapter to hook it to my laptop. The laptop is running Windows 10 and can support two monitors, I disconnected the second monitor from it to hook up the cintiq.
The pen function on the cintiq is working but the monitor part says "No Sync - Go to Sleep".
I've googled EVERYWHERE and tried a ton of different things to get it to work. Unplugging and plugging all the wires back in. Restarting the computer. Uninstalling and reinstalling the Wacom drivers. Trying a VGA adapter instead. I don't really know what to do at this point.
