HELP: tuning Picasso96 and PIV to flat screen

[Tenacious]

I can't tune Picasso96 to work with the native resolutions of a couple of LCD flat screens I have acquired.  The stock drivers appear to be designed for CRTs with higher frequencies, and, these have always worked fine with CRTs.

Both of my flatscreens (an ETC - 1360 x 768, and a Dell - 1280 x 1024) want a 60Hz vertical frequency.  I've read the docs and tried to use Picasso96Mode and PVS to adjust to the required freq, the only resolution I can get working is 640 x 480.  If someone else has found this obvious and straight forward, please explain it to me.  Is there a good tutorial somewhere?

My system: A3000 with 060 and PIV running OS3.9.

google-translate should help

Thanks Ratte.  Without reading German, it appears that thread is primarily about UAE, which still might be applicable to my ignorance.

I would have thought there are many people running P96 on classic Amigas, with wide and normal aspect ratio LCDs, who have long since fought this dragon.  How many Picasso boards, not to mention all the others that are compatible with P96, are still in use.  Part of my reluctance to experiment beyond a certain point is the rumor that incorrect settings/frequencies can destroy a monitor.  Perhaps that is less true of LCDs.

It's been a couple of years since I fine tuned the PIV in my A3000/060 to my LCD but I will be having to do it again soon as i've been rebuilding it as time permits recently.

You might want to try the tool linked at the bottom of this page as it's "easier" than the default P96 tools.  Wouldn't be a bad idea to upgrade to the most recent version of P96 from this page either though not strictly neccesary.

nicholas: thanks for the link.

I also have a Picasso IV and I, too, have had problems setting it up. I managed to get it working with my LCD (even the screens native resolution, something as crazy/high as 1680x1050 works) but I still haven't figured out how to fine-tune the settings for the PAL/NTSC flickerfixer modes - it works but there is heavy vertical banding on the picture.

Thank You Nick!

PicassoModeTNG is much superior to the older PicassoMode.  

The only thing I stumbled thru was saving.  I had to save as Default configuration.  Reboot to load the new screen modes. Return to ScreenMode to select the preferred screen mode.  Reboot again.

PIV doesn't have unlimited resolution/bandwidth.  I couldn't get the 1600 x 1200 to work at all, nor 1280 X 1024.  1024 x 768 x 16M @ 60Hz looks pretty good on the new LCD, though.

It appears I may have to go back and tweak the native screens, but now thanks to you, it won't be a guessing game.

Good job!

It is for CLASSIC Amigas !!!
If you translate it, you will noticed that the last modes are made for classic systems that runs 68k-uae (yess .. o6o/o9o+ can do ..)
Follow the instructions, it absolutly simple.

Import the settings-file, attach it to your graphiccard and say "yes" to erase unsupported modes.

Thats all.

Done it when going from CRT to LCD - not difficult, just simply tedious going back and forth in settings to get the screen size and refresh to fit to the LCD.
