If you do not uninstall every tablet driver lurking on your machine before you try to install the Ugee drivers, it will not work. Setup will throw its juice box on the floor and cry.
Don't use the CD that comes with the tablet. Go to ugee.net and get the latest drivers there.
It has both a VGA and a DVI port. You only need to use one or the other. But it only comes with a VGA cable, so be advised.
While you're out getting a DVI cable or an adapter because who the fuck even has a VGA port on their video card these days, pick up a longer USB cable.
Works great in MediBang Paint Pro, Clip Studio Paint, and Photoshop. Some brushes behave weirdly in SAI but I don't really use SAI much these days anyway so that's acceptable. Haven't tried it in Krita, Illustrator, or some other stuff yet.
Some folks have reported it working fine in SAI? Maybe there's something I need to tweak?
Probably 99% of the problems I've had with marks not appearing where I expected them to is just from me looking at the thing at a weird angle. note to self: stop doing that.
