No display at boot up

  Gandy 13:45 04 Mar 2005

I have an Acer LCD monitor, which cannot display boot messages as they are "out of range".

On inspection with a crt monitor, they (the boot messages) do appear to be 'squeezed'.

I don't get any display from the LCD monitor untill the ati drivers are loaded.

Any idea how to get my boot messages back? Bear in mind I can't see the screen to select safe mode, neither can I get a display when trying to enter the bios setup.....I have no display till Windows has loaded.

What has changed to alter the V/H frequencies and/or resolution during boot?

It has worked and failed previously, but have no idea what I did to correct it last time!!

Need more details here...

Try this: boot up using ur crt to get into the bios. check that u have onboard graphics card (if any) disabled and agp selected as video type (I'm guessing what ur setup is here...)

could also try the settings buttons on the screen itself (again, assuming you have any)

agp selected in bios.....monitor buttons have no effect. The message "out of range" with values of V and H frequency and resolution is all I can see at boot up, so presumably, something is wrong with these. But controls display settings at boot up?

sorry, missed the word 'what' in last sentance!

Ur bios controls ur display on boot up. U still havent said if u definately have an agp card.

But further than that I'm out of ideas now....

Sorry, it's an ati radeon 9200 on a MSI KT6 Delta mobo. Do u think there could be a clash with the mobo vga drivers and the ati card?

proper cable (not very long) is two ways, so when PC start, it send request to monitor and the monitor answer back about the resolution and PC set it properly

if you have a dumb cable (only one way), PC cannot get any answer back from monitor so it just set the highest resloution of the graphics card, so you got out of range info (or "squeezed")

It's a Dsub cable, that came with the monitor. Pc is supposed to auto detect monitor (plug n play)

suppose feedback line is damaged

only plug n play if cable is two ways
