I have ditched the two old TV screens and got myself a 7" widescreen VGA monitor with serial touchscreen. This also means that I didn't have to finish the USB touchscreen controller as well. (I want to finish it later though...) Very soon I modified the rather fragile input connector into a 26pin high density Sub-D connector, which also transfers the power to the monitor. Meanwhile, here is the pinout for the original connector (pin 1 is closest to the bottom):      1)  VGA pin 1 (RED),      2)  VGA pin 2 (GREEN),      3)  VGA pin 3 (BLUE),      4)  Audio in,      5)  Ground,      6)  Ground,      7)  Ground,      8)  Serial touch pin 2 (on female Sub-D),      9)  Video 1 in,     10)  Ground,     11)  Video 2 in,     12)  Ground,     13)  VGA pin 13,     14)  VGA pin 14,     15)  Serial touch pin 3 (on female Sub-D)
