Dell flat screen monitor problems

[Stephen Howe]

Hi,

Have a Dell Optiplex SX260 with 1504FP flat screen, Intel Extreme Graphics
82845G, analog cable.

If I run some old DOS software that launches in text mode, switches to
graphics mode and eventually switches back to text mode - it all runs no
problem.
The DOS session while in graphics mode runs fullscreen and in text mode
afterwards after quitting is in fullscreen mode.

But at this point if I press Alt-Enter to windowise the DOS text box and
restore the Windows graphics screen, the monitor goes black and a monitor
message saying "1. Analog Input".
There is nothing for it but to reboot. I have tried turneing off monitor and
on 20 second laters, fidd.
How can I change this?

I want to run the old software and somehow restore the graphics session of
Windows afterwards.
I checked Dells web site - found nothing on this, FAQs, support etc
There is a USENET newsgroup on Dell - will try this later.

I have something else I will retry and that is to enable the Monitor hotkeys
and try Ctrl-Alt-F1 which does "enable monitor"

Anything else I should do?
Perhaps change something under _DEFAULT.PIF properties ?

Thanks
