Hello, ive got a hercules prophet 7500 128MB ram and ive connected two crt vga monitors to it, the one uses a dvi to vga adapter. This one the screen is really blurry. im using identical monitors and if i switch them around the other one becomes blurry. Ive bought a high quality dvi to vga adapter and this doesnt improve anything. how can i make it un blurry?!?!?!?!?!
