Just put an LCD monitor on an A4000 for the first time and I have a question..

[A4000_Mad]

Hi Guys,

After using the CRT monitor in my profile pic on my A4000 for years I bought my first LCD one for the Amiga yesterday. I'ts a 15" Philips 150S1C/00Z.




The CRT monitor has a nice, clear display and even old games scan double onto it nicely. However, the picture on the LCD monitor is very grainy and when old games are scandoubled there are very noticeable vertical lines on the screen.

I'm no expert on frequenceis etc, but from reading an online manual it is clear that this monitor likes 60 Hz. Could the problem be that the Picasso II being used and the motherboard mounted scan doubler are producing only about 50 Hz? I guess the scan doubler cannot be adjusted, but could the Picasso II driver be altered to make it deliver 60 Hz?

Thanks,

Thanks very much for your help guys

A very detailed manual was here:-

I used  its OSD 'auto adjust' and 'video noise' functions and got some improvement and also had a nervous tinker with P96Mode. But in the end I used my brain cell and realised it made more sense to just put in on the A4000 with PPC and Cybervision64/3D which I mainly use for emulating arcade games with MAME and Sega Games with AmiGenerator, and also for watching videos with Amp and FroggerNG. Although capable of scan doubling, I never need to do it with this particular machine as I don't run old games on it. The Cybervision64/3D must be set up better or just a better card as I'm getting better screenmodes and a perfecly still picture


EDIT

@ Selles .. You were spot on with that thanks
