2. Single link DVI-D connectors can support 60 Hz up to ____ x ____ resolution.






3. The ____ contrast ratio indicates the difference that the monitor is capable of producing.






4. The ____ is the distance between pixels. A lower number means a sharper image and possibly higher resolutions.






5. LCD monitors often include features for HDTV support such as an HDMI input that accepts ____________ through the HDMI port.
