hmm... I installed this

Verstion 1.4 from this site

I've been away for the weekend so i've not had time to mess with it any further.

Is 1.4 from this site ok?

Thanks!

It's dead old, Aminet has at least 2.0.

Guys, got the PicassoIV working now :)

When I change the resolution it comes out on the TFT ok but when I reboot it doesn't seem to save the settings after rebooting it.

Which file should I modify to get the resolution to stay or have i got something configured incorrectly.

I'm using screenmode in prefs to select the res.

Thanks again!

Use "Save" button instead of "Use" to make the change permanent.

If you did and it didn't work, make sure that Sys:Prefs/Env-Archive/Sys/screenmode.prefs is not write protected.

Bye,
Thomas

Sorted! I deleted that file rebooted and now it saves OK. Thx!

I thought these picassoIV's had a flickerfixer in them? I'm setting the resolution to 1024x768 and it shows as interlaced only.... the picture on the my TFT seems "interlaced" to me.

I went into picasso96mode and tried testing it with interlace unticked but the tft then can't display the image.

maybe i'm expecting a little to much from the Picasso?

Check the frequencies which are shown at the bottom of the page and make sure that they are still inside the monitor's specs. Deactivating interlace doubles the horizontal frequency. You have to decrease the pixel clock accordingly so that the frequency gets back into the supported range. However, changing the pixel clock influences both, the horizontal and the vertical frequency. So you probably have to experiment with the sync values, too, to stay inside the specs.

Thomas your a star! Thats sorted it now it looks great!

turned interlace off and then adjusted pixel clock until hor & vert freq's were at 60 & 71 hz

Looks perfect now.

Thanks!!
