I won't define this monitor to judge "correct" PAL signals.

My PAL IIe board from a French IIe (made 1984) outputs "correct" colors
on a standard TV set. My only gripe with the picture is that it is
"squashed" because of the higher linecount of the PAL system.

The above mentioned PAL board has this feature, too.
Most noticeably in the text window of a mixed graphics mode.

No surprise - it uses an "International NTSC" board. Which outputs a
travesty of a video signal (NTSC at 50 Hz) - which is even worse than
PAL at 60 Hz.

A good sign that this monitor has some creative understanding of video
standards.
