[comp.sys.ibm.pc.hardware] Sony 1304 Display Problem

kipp@gistdev.gist.com (Kipp Kreft) (01/19/91)

I have a Sony 1304 (with a Gateway 2000 33MHz system), and I noticed after
about a week of using it, that there is a barely noticeable horizontal
shadow about 33 to 40% up from the bottom.  It is not so dark as to make me
think a scan line is out, and it is evident in all modes/applications.
I have the standard issue Diamond Speedstar 1Mb video board (Tseng 4000).

The Gateway tech. said that every Sony 1304 has this "feature".  He said
it is a wire that causes the slight shadow on the screen.  Can anyone
confirm/refute this?  (BTW, I am happy with the system, 200Mb Maxtor.  The
so-called "shadow" is barely visible, and the Sony 1304 looks great.)

All tubes of this type from Sony have that line.  My friend had a
color Mac screen that uses the same tube as the 1304 and he had
the same wire.  Nothing to worry about.  Just slightly annoying if
you are a purist.

I believe this is normal for a certain type of tube.  These are called
"flat tension mask" monitors, I think.  The IBM RS/6000 monitors we have
here have two such lines each.
