I suggest looking up the specs for LG or Samsung LG190E08 or similar series=
=20
- the 19 =3D 19" in the part I just mentioned the E08 series use 5v for the=
=20
screen drivers. Older series use 12v and very new ones can be 3v3.
The screens themselves are mostly interchangeable, differences being some=20
will have 6 backlights, though your picture shows a 4 tube backlight=20
arrangement.

The touchscreen side is another thing altogether, perhaps it's a 3M=20
controller or maybe Touchstone (Hmm sounds right).

The backlights will need an inverter which is often 12vdc fed and are as=20
mentioned around the 800 - 1k6v.

The most essential thing is the voltage to the panel, the panels have no=20
voltage regulator of their own (the ones I repair don't anyway), feed too=20
high a voltage to them and you get a nice bright white screen, not that=20
I've ever done that of course. :)

The HP monitor power supply itself may well be made by  Benq in which case=
=20
the backlight inverter is part of the main power board, if you search the=20
interent (sic) you can pick these up surplus or as spares from various=20
monitor repair suppliers.
