I am absolutely not up to date when it comes to hardware. I have this Dell Optiplex 755 that only has an onboard D-Sub output, but I want to use the machine to watch videos on a large Samsung LCD TV.
Now the LCD comes with a D-Sub input but I'd rather use a HDMI connection so I'd need a new graphics card. The case is however smaller than computers I am used to seeing, so what graphics card do I need to buy for the machine? The slots at the rear of the case only measure 7cm or less.
Note that I'm asking for the term used for the graphics card and not actually the graphics card.
