GVP Spectrum+A1942 display problem

[jagoche]

After a while I have connected my old A1942 monitor to GVP Spectrum. Colours on the display are really PALE! Both, Spectrum and native A4000 AGA modes

If I connect the monitor directly to A4000 video port, the colours are normally bright (right most image).




Images from the left:
1. Spectrum 16bit mode, monitor connected to Spectrum VGA port.
2. A4000 AGA 8bit, passthrough via Spectrum, monitor connected to Spectrum VGA port.
3. A4000 AGA 8bit, monitor connected to A4000 video port.

Is there an explanation, why Spectrum "kills" colours? The problem doesn't seem to appear on LCD monitor.

Thanks for the tips.

Indeed I had to replace two broken capacitators a year ago. See the post here.

The thing is that while a LCD monitor was connected to Spectrum the picture was OK. The dim look only appears with old A1942.

I was curious if other Spectrum users have experienced similar problems with old monitros?
