I have an Acer Aspire desktop x1420 with Windows 7. To run two monitors I added a ATI Radeon HD 5450 card. The computer still sees one monitor and the new video card. I am told I need to update the Bios. The Bios vendor is American Megatrends Inc, date 4/20 11 DMI version 2.6 Bios version P01***TRIAL***. I have not been able to beat windows start up to get to the bios set up,but when i do ... what do I want to update? I am a novice. it's taken me hours to get this far...

do you have two video cards installed or one video card and the other is the onboard(motherboard) graphics?

to get into the bios you should shutdown the computer(not restart)
then push the power button and quickly push the key to enter the bios. (usuely f2, or f10 but could be other keys)

im guessing u will need to find a setting in the bios to enable the onboard with the 2nd card installed. should be something along the options that says "onboard video": enable, disable" or "video": onboard, pci-x, both. if the the first case u will select enable if 2nd case u need to select both. due to various bios I can tell u exactly what the setting will be called or the options available. this is just example of what u should be looking for in it.

If windows managed to successfully recognize and install your new video card then there's no need to update your BIOS.

ATI cards by default recognize only 1 monitor so you need to do the following:

Make sure you have ATI drivers installed (not the generic ones windows automatically installs), then in AMD Vision engine control center (right click on desktop-> AMD Vision engine control center) go to "Common Display Tasks", finally choose "Detect Displays", that should get the 2nd monitor recognized.

I did not take anything out of the computer so I have two hookups to two monitors, the old and the new. Thanks for the help.

I installed the drivers from the CD that came with the video card. When I followed your instructions it replied: Detection complete and showed one monitor. Under it was: "il225DBB" The reason I'm sure the computer is seeing the new video card is when I was trying to find info about the bios version, under Video Processor it says AMD Radeon Graphics Processor (0X68F9) Just to be sure, I just unplugged the monitor attached to the new port (back of the computer) and the only monitor that is working went black. I've checked the cords on the other monitor (attached to the old port). I can switch the cords and the other monitor is working fine. Thanks for your help.

go to ur device manager, select ur "old video card" and then hit roll back drivers, hit yes to any warnings. then reboot then try to enable the 2nd montor again. installing from the cd may have installed the incorrect drivers for your old card.

There is only one video card showing (the new one) when I go into device manager, however, i've made it into the bios. under "integrated peripherals" "onboard graphics controller" is disabled. that line is grayed out and will not let me enable. if i did a system restore to a few days ago would that reinstate the old video card? could I enable the onboard graphics controller then and reinstall the drivers for the new video card

When you install a dedicated graphics card, you cannot use the on-board one anymore, to have dual monitor, connect both monitors to your HD5450.

After that, follow the directions I gave you earlier to get the 2nd monitor recognized.

I said I was a novice - so here's major dumbness - How do I do that? .... There is a plastic ribbon connected to pins on the video card. The other end is the serial port I am using that works. I have another a plastic ribbon but I only see one set of pins on the card (the ones already being used) Is there a splitter I need? I appreciate all the help,

i'm guessing the HD5450 has various inputs such as DVI, VGA, and HDMI? if so, in order to use multiple monitors, you need to have one monitor connected to each of the inputs. They sell DVI to VGA connectors in which you can use if both of your monitors use VGA ports. Like everyone said, you cannot connect one monitor to the video card and the other monitor to the onboard graphics, both monitors have to be connected to the video card.
