When I initially built my computer I had my old 15" CRT connected. Everything installed and ran fine. A few weeks later I purchased a 19" ACER flatscreen which I am now using. The problem I am having is that the BIOS won't recognize the new monitor on startup. I'm running Vista and once it loads then the monitor works fine, but from power-on until the login screen I'm not getting a signal to the monitor. When I hook up the old monitor the POST and BIOS screens display just fine.
How do I get the BIOS to recognize the new monitor from power-on? Is it a BIOS setting, or a problem with my video card (Radeon 3850)? It's not a crippling issue, but it is annoying to have to plug in my old monitor everytime I want to make a change in the BIOS. I've tried clearing the CMOS several times to no avail. Any help would be greatly appreciated.
P.S. I'm running the most current version of the BIOS.
