I have three of them and think they are great! Two are my main monitors for Toaster/Flyer control screens with four 1084S monitors for Preview and Program outputs on the two editing stations and the other is my TV in my Bedroom.
It is not a great computer monitor, but is a good TV and is great for Amiga due to its ability to multisync to 15kHz and 31kHz display frequencies. I don't know about PAL as I am in the USA.
I have not played games on it (yet), but would imagine for an A1200 AGA display the standard NTSC and 640x400 interlaced modes would work the best.
It is big and heavy, takes a huge amount of space, doesn't have headphone jack, has a 15pin RGB input, standard RCA video and stereo audio input jacks, and a coaxial TV input.
Sound is decent from the built-in speakers and the TV picture is very good.
I would not part with mine, as they are so multi-talented for Amiga work. :-D
Edit: 800x600 is the maximum resolution listed in its documentation, so I would worry about pushing it to 1024x768 if the monitor was mine.
