Can't get decent resolution from Cybervision Card

[Tumbleweed]

I too have experienced similar problems with my CV64-3D with scandoubler on an LCD monitor. I can get 1024x768 and 800x600 to work but nothing else. AGA screen modes scandoubled are displayed but with a "frequency out of range" error.

What I've found is that the range of supported modes on LCD screens is not as wide as traditional CRT's. I have tried 15" and 17" LCD's and they both have issues.

What I have done now is to use 1024x768 for workbench (which works) and for other modes not supported by the LCD I use a CRT hooked up as a second monitor. Not an ideal solution but it works.

Fiddling around with P96 settings, try turning interlace on, scan double off, or other combinations can help.

@Skilgannon - what brand is your 22" monitor? Do you know what its minumum and maximum H and V frequencies are?

Also when you use the test mode in P96 the screen should revert back to what you were using initially after a short period of around 30s or so.

If you have no joy at all with P96, you could try cybergraphx. Some say its better for CV64 than P96.

What's in your devs/monitors drawer? You should have a driver along the lines of CV64 (possibly with a 3D at the end, I'm not in front of my miggy at the moment to check). What other drivers have you got in your devs/monitors drawer? And which port on the CV64-3D do you have your monitor plugged into - the one for the scan doubler or the other one for the CV64-3D?

Here's how I've got mine configured.

1. Monitor plugged into the output from the scandoubler.
2. Scandoubler linked to CV643D by small ribbon cable
3. CVision3D monitor driver in devs/monitor also Pal driver in devs/monitor. No other monitor drivers.
4. P96 Mode configured as follows

1024x768 256 Colors H:57 KHz V:70hz clock 75.17 MHz - this mode works for me.

1024x768 HiColor H:51 KHz V:63Hz Clock 70.40 MHz - this mode works.

Try these values and see what happens. These work for me on my CRT, 15" LCD and 17" LCD. My LCD's are IIyama Prolite E383S for the 15" and Hyundai L73D for the 17". The CRT is a LG Studioworks.

Hope this helps.

PS I can send you my P96 config file if you want to give it a go.

Damn - broke the workbench lol  Think I selected a mode and saved it that it can't do  doh!

I hate when that happens. Best way to get out of that situation Ive found is boot from Workbench 3.1 from floppy and remove the CVision3D driver from devs/monitors from your boot partition om your CF card. Then reboot.
