Weird vertical blurred areas on GFX card output

[asrael22]

Hi.

This is really weird. But also annoying.
The GFX card output on my A4000 has areas, vertical bars of maybe 2 cm width, every 6 or 7 cm, where the output is slightly blurred so that text is harder to read and is not sharp. There is not a different color or so, it's just that's is not sharp in those areas.
I have this on two different GFX cards. So it might not be the GFX card.
What else could that be?

Thanks for responding.
I see this phenomenon with a Piccolo SD64 and 'Matze's Grakka' on Picasso96-2.1_e.
Hmm. I had a different display on it but for other reasons. So no, I haven't tried different cables and display. Will do that.

So it seems to be the display. Or a combination of the resolution and the display, maybe also the analog input. Putting a digital input on the display it has no problems.
I've put another display on the A4000 and all is fine.

So thanks for the pointer.
