PAL TVs definitely had scanlines, you probably just weren't thinking about it. Obviously 288p scanlines are thinner than 240p scanlines. 240p/288p being the gaming resolutions, obviously when displaying TV content it would be 480i/576i, which would have much less visible scanlines.

I don't have played my games with a TV, never... only with CRT displays for PC and some LCD and similar

Why you dont use a sourceport for this game??
GZDoom for advanced engine or prboom+ for purists.

Prboom+ cause some problems here and GZDooM is too diffent

You can configure GZDoom to be quiet accurate.
Or try GLBoom, or Crispy Doom. There is sure a sourceport which works for you.
Or try some troubleshooting. No one has to suffer through dosbox for an id game 🤣

Hexen II is a windows game, not a dos game...

Not sure you can complain that he's going off-topic after you specifically joined in on it? You were talking about PrBoom and GZDoom, which can't run Hexen II either.

Also with the right settings I doubt most people could tell GZDoom and DOS Doom apart most of the time.

I somehow have overseen the 2 part. I thought for some reason it was about hexen 1. Sorry!

Except that the phosphor matrix (I don't know the proper name) usually didn't look like this

1RGB RGB RGB RGB
2
3RGB RGB RGB RGB
4
5RGB RGB RGB RGB

(which could give clearly visible scanlines), but more like this:

1RGB     RGB
2    RGB     RGB
3RGB     RGB
4    RGB     RGB
5RGB     RGB

making them invisible, perhaps at the price of blurring the picture a bit.

Link to a source on NTSC and PAL differing like that? I really don't see why they would.

I don't have a source, I'm only saying from my personal experience. Also I don't claim that all PAL TVs look like that, but the ones I've seen did.

Still doesn't make any sense. I'm still thinking your memory is probably faulty, or you're thinking of 576i.

We had a Russian color TV back in the end of the 80's which had a 'delta' cathode ray tube with the same (or very similar) RGB arrangement as the second one in Azarien's post. I remember it because my mother always told me not to look at the tv so close. Later we changed to a more modern one, and that had 'in-line' CRT, with pixels made of vertical lines of RGB. As far as I know, they were just different CRT technologies, independently on PAL/NTSC.

Same exoerience here.

There are TV attributes that can make scanlines less visible sure (I'm sure CRTs had different levels of light bleed too for example), but there isn't a PAL/NTSC difference between scanlines except being less noticeably with PAL because of the slightly higher resolution (288 lines vs 240).

I think you would still notice them on any SD CRT if you were looking for them.

Edit: looking at how this started, I think it might be my mistake with a bit of misnomer that 400p has "scanlines", which I think only refers to the 480i/240p hack (obviously there's still a gap between lines even in other modes, but in 240p I think every other line is actually blank? I'm not an expert on this).
