No signal until Windows has loaded

I've installed my old 4850 into my brothers computer and I don't seem to be getting a signal on the monitor until Windows has loaded. Its connected to a LG 22LS4D by VGA but is using an adapter to convert the DVI output on the card to VGA. I've tried it on my Dell monitor via the same method and it works fine, can see the BIOS splashscreen all the way through to Windows desktop. Any ideas why its not displaying anything on the LG monitor until Windows has loaded?

How odd. New card set in BIOS to be first Display device? although having no bios screen infront of you might be a problem :o

I think it is, haven't changed anything in the BIOS since removing his old card (ATI 4670), but as it works on the Dell monitor, would that rule it out?

Sounds like a driver issue if it's waiting for the OS to load before you get signal. That's my guess anyway, was there any software for the screen? Long shot, but give it a go. I wouldn't have thought it's an ATI driver issue if the dell screen works :/

Don't think there's any monitor software (its actually a TV but shouldn't matter). Perhaps its an issue with the resolution its displaying (out of range?) before it loads Windows? Having said that I had no problems with the 4670 that was in it previously which was using the VGA connection.

Jon20, plug the monitor into the other port on the 4850 and then you will see everything else before windows boots up.

The other DVI port? Its this 4850 btw http://www.overclockers.co.uk/showproduct.php?prodid=GX-106-PC&groupid=701&catid=56&subcat=938. It only has 2 DVI ports, I did try both but it didn't display anything on either until Windows had loaded, but I shall try again in the morning. Its not a major problem other than the fact that I can't see to get into the BIOS if I need to.
 
Thanks for all the suggestions guys. I've connected it using HDMI as gareth170 suggested and its working fine now. Obviously for some reason the TV doesn't seem to respond when using DVI>VGA adapter>VGA connection and yet it works fine when just using straight VGA>VGA connection, like I did with the 4670. Just means I now need to get a longer HDMI cable.
