My card is a Gainward Geforce 4 NVidia FX5200 with a DVI port and an analog port. My monitor AG Neovo has a DVI and an analog port. Everything is OK on analog but when I connect up the DVI I get a "no signal" message. Does my card really support DVI? If and when I solve that problem is it OK to keep the monitor connected to bith connect both inputs ands switch through the OSD?
