You could try contacting customer support, but I dunno how much help they'll be since your tablet is nearly 2 years old. Worth a shot, if you haven't already done that. Hmm, I knew that company sounded familiar, but wasn't 100% sure where I first heard about it. After some searching, I remember that I was talking to another artist on TBT, feavre, who has a tablet from the same company. I dunno if they have the same one as you.
From what I saw in our past conversations on drawing tablets, they have the Yiynova MSPU tablet monitor and like you said, it's a fraction of the price of the Cintiq. Apparently, in their experience in using both that tablet and a Wacom Intuos4, they mentioned that the Yiynova one has better tracking and pen pressure... at the cost of not as good resolution.
I would say you can contact them, since they might have some better insight, but... I haven't seen them actively on TBT in quite some time now. They do also have a tumblr and DA, so that's another option too. :3
I actually did talk to them for a bit before I made the purchase - or I should say, they contacted me. But that was mostly because they wanted to sell me a "cheaper" one that had been refurbished from having some dead pixels---I said no. I did take the opportunity to ask them some questions, though. The only real problem was... I'm pretty sure they were Chinese and I was having a pretty difficult time understanding their English some of the time (it wasn't that bad, but when talking technical terms, it gets a little jumbled). Anyway, pen pressure is what should be responding well, but it doesn't. It responds in thickness, but not in movement. And other programs I've tried simply don't work at all (like CS5, which would literally only draw straight lines out of nowhere even if I just touched the pen to the screen). But I did mention the drivers in my questions and they said something about them being tricky to find for "old models", which is what my crappy old tablet was. So my best guess is that there's a hidden Wacom driver in my machine somewhere and I don't know how to find it. I googled literally everything I could think of on the matter. I've also reset the pen precision and detection on screen more times than I can count.
Yinova MSP19U is the one that I have, though. (U is supposed to be an improved, better version of the MSP19) As it is, I can't complain too much, because it allows me to digitally color pretty well. And I would have had to give up digital coloring altogether if it weren't for a tablet monitor. My wrist and CT problem was largely in part from digitally coloring with a mouse for over over 8 years. (I definitely don't recommend it.) By using my tablet monitor, however imperfect it is, I can still continue my craft. And without having to drop $2000 on a Cintiq.
But thanks for the tip! If I happen to see that user around/find them elsewhere, I'll ask them about it.
