Default ultra 5 and LCD equals black screen

Hi,


I have an Ultra 5 with PCI video card (M64 rev 47549a). It works fine
with my Compaq V700 monitor but I want to replace this one with a LCD
screen. But after I do that the LCD screen is black. I tried m64config with
no luck. I don't even see the Sun logo when I boot the machine. I know for
sure that all cables are OK and the LCD works fine with my PC. When I reboot
the Sun I see the LCD on/off LED turn green for a second ( I think it then
tries to communicate with the Ultra 5) but then turns amber and the OSD
shows a picture that the connection between the computer and screen is
lost.

I think the problem is sync problem. The Compaq uses separate sync and I
read somewhere that the Sun does too. So I suspect the LCD does not use
separate sync.

I don't know if I have the latest patches installed, but do patches also
affect OpenBoot? Because I can't see OpenBoot does it mean I am a step
before the possible patching issue? First I have to get it so far that I
can see the machine boot, don't I?

By the way the output of fbinfo is:
mb64B@2 is PGX 1152x900
(I get this output using the Compaq Monitor)


If this turns out to be a sync problem do you know of any converters to make
this work?

Hopefully you can shed some light on this.

Bye,
Dick

Set it to 800x600 or 1024.768
1152x900 is a Sun standard which many monitors will refuse to grok.
This is more of a problem with modern digitally controlled
monitors, the older ones with analog internals would often work.

Ok, but if that were the problem shouldn't I see the system boot then?

I think OpenBoot uses a different resolution than Solaris, doesn't it?

1152x900 is usually composite sync on a Sun.
try 1280x1024x60 (about right for a medium size flatpanel)
or the other res's mentioned below.

fbconfig (m64config ???) sets resolutions for the window system after Unix is
up and running. There is usually a different way to set an fcode option to
set the res at bootup time. (something like screen:r1280x1024x60 on some
cards, but check out the specifics for your card).
