We do have a HP 7700 pc that came with an on-board VGA port as well as DVI port on a pca adaptor card. TVGA port is not working, and would only works if I remove the video adapter. It is enabled in the bios and the other choices i ahve are IRQ 5, 10, and 11 whicha re used bu usb.
It seems that viedo adapter automatically disables the on-board vga port. Is there any way to enable both with having to purchase a new dual-port dapater.
