Powerbook 190cs, Passive or Active Matrix?

#1 Sat, 31 Aug 2013 - 22:37

I found this confusing:

http://www.everymac.com/systems/apple/powerbook/specs/mac_powerbook190cs_66.html

The summarized description at the beginning says "Dual Scan" for the screen, but then further down it says "Active Matrix".

As far a I'm aware, Dual Scan is passive matrix technology. If I'm right, which section is correct, the summarized description or the spec listing?

Also, I'm already aware of this page:

http://support.apple.com/kb/TA21582

and I've already discovered two errors on it previously, so I really don't consider it to be a reliable source of information.

the "cs" suffix always denotes a passive matrix/dual scan etc as opposed to "c" for active matrix AFAIK.

everymac seems a bit more reliable for info than LEM, but both have errors and in one instance I found them both to be incorrect, while offering differing information, IIRC.

i agree, C = Active Matrix / CS = Passive Matrix

Definitely passive matrix, and as I recall pretty blurry/grainy in color mode. When I had a 190cs I mainly ran it in black and white for clarity.
