Hi, i have bought a Diamond Stealth Radeon 9250 256mb PCI graphics card. After i disabled my onboard graphics card , just like the manual said, i connected my samsung syncmaster 700df monitor ( i know it sucks :[ ) to my graphics card, but when i turned on my computer , my monitor was black, but my computer was running fine. When i connected the monitor back to my onboard it turned back on. I am not really sure what the problem is.. I am sure I have everything for the system require for the graphics card EXCEPT super vga compatible or dvi-i compatible which i do not what it means. I would really like help :]... Thank you -------- Edit -------- I would like to know how to find out if your monitor is super vga compatible or not..
