The second photo looks bad, but I can't tell what's going on.

Each display has an optimal voltage on the common element ("Vcom") that is labelled on the connector ("-2.25").
This is a value that is tested at the factory.
I knew where this value was stored on some of the B&N models, but I've not noticed it on any of the Onyx.
Thank you for your information. The first one is not so bad but will be worse soon (the second was not bad at first after several days was worse). Regarding to Vcom, I noticed it and adjusted the right one after I flashed the ROM with mfgtools. I have bought several displays from one seller. They have the same problem. So I don't know whether it is my problem or the display had problem.
