Some time ago I wanted a good external display, and I tried several. Of the three monitors I tried the Lenovo ThinkVision LT1421 came as the winner. After a good time with it I felt like it would be neat to have a display and a tablet all at the same time. Wacom does offer the expensive Cintiq systems, but those require an external power supply, several cables, and they are not as portable as I desired. So my search took me to Lenovo's usb powered tablet display: the Lenovo ThinkVision LT1423p. This later display seemed to have exactly what I wanted, but it just wasn't released. After looking around I found a Yiynova DP10HD and I had to try it. After initial testing the Yiynova's N-Trig like pen input did not satisfy me, and I knew I had to find something with Wacom's technology. In the last days of April I investigated Wacom's website and saw a new product listed: the Wacom DTU-1031. The product was not yet available, so I gave them a call and the sales rep didn't know anything about the new tablet. On the very last day of April I noticed that suddenly the DTU-1031's webpage had a clear price and the order button was enabled. I placed an order for the Wacom DTU-1031 and ended up with two competing 10.1 inch USB powered tablet displays. Sadly, I could not do proper DP10HD videos because the system wouldn't work after around two weeks worth of use (perhaps the USB port went bad). Now I only have the DTU-1031, but I did take some pictures of both systems. Enjoy!
The Yiynova's body and screen are wider than the Wacom's. Also, the buttons on the Yiynova consume more space than the Wacom's buttons. Regarding the screen, I think the Yiynova's is brighter and more colorful.
The two stacked on top of each other. The Wacom has a better pen holder.
Both have a similar thickness, the Wacom is heavier but also offers a higher quality body finish; the Yiynova's body is plastic.
The Yiynova allows a more steeper angle, which will be convenient for those that need to compare documents. The Wacom's angle is more suited for "hands on" tasks.
