I have had an AMD 5450 in my PC for several months. I just bought a new 24" Samsung monitor and can't figure out why the monitor looks fine at 1920 x 1080 when connected to the on board graphics card (with the AMD card out). But when I install the AMD card, the monitor stays at 1680 x 1050.
If I change it to 1920 x 1080, all the icons get bigger, not smaller, and the image is then too big for the screen, so stuff to the left and bottom can't be seen or accessed.
Have I done something wrong? What am I missing. I'm usually pretty good at all this but I'm at a loss. Could it be the BIOS? It's not a very new PC...Core Duo 3.2 ghz or something. Still, it works with the on board graphics but not with the AMD card.
Thanks in advance.
