While I was trying to solve this same problem I came across this thread so I figured I'd chime in with what problems I had.
My problem is identical to yours and has the out of range error while the computer POSTs, but works fine once Windows display driver is loaded. The problem is not my LCD and I assume you have an LCD as well because you will find that you won't have this issue with a CRT.
What has happened is that video cards have a normal default resolution for BIOS, which is usually very low. The problem I was having is that the vertical and horizontal frequency outputted by my video card in bios was all cracked out. For some reason, it was set to a non-standard frequency. You can find if yours is doing that by using a CRT or another monitor that works and booting into BIOS. Looking around in your OSD (on-screen display) and somewhere it should tell you either the resolution or the 2 frequencies.
The issue is LCDs will only operate within certain resolutions and frequencies, whereas CRTs can be forced into almost any. So the problem is not your LCD (which is what I thought was my problem too) it is in fact some setting for your video card, be it in the BIOS or in the firmware of the card. This is why once the Windows display driver is loaded, everything works fine because now the card is outputting a standard resolution that is supported.
Likely to solve the problem you will need an updated version of your BIOS that use correct resolutions/frequencies.

                    Wow, that's weird man! Never seen that before. Especially strange as you'd expect the BIOS to be low resolution rather than high! Only things that spring to mind are obvious: Video card problem or maybe try and flash the BIOS? I'd try the monitor on another PC to rule that out (maybe it's on its way out) Try and reset the monitor if it has user settings that can be saved. If you boot into DOS does that work? Not sure exactly what that would tell you though, but if you can't then you might have problems flashing the BIOS if you felt that would help. Scratching my head otherwise though! S

                    You're telling me! I can't see how the graphics card is the problem, as I said the gfx works fine once it is loaded. I don't see why it would not display in 640x480px 😕 um, could I reset the mobo back to factory defaults using the jumpers? I'm not too hot on hardware, to be honest. Regarding the monitoring being on its way out, that sounds about right - if I remember correctly the warranty ran out at the end of April 🙄

                    Yeah, they normally have a CMOS reset on them where you change a jumper position, reboot and wait for it to bleep or something then shut it down and put the jumper back how it was. Try looking in the manual or the website for the board or post details here and I'll see if I can see it. Regarding the warranty, I swear they build timers in these days so they break when it's a month out of warranty! It's a conspiracy! 😱 S
