5. LDC monitors use ____ panels that are the most common type used in computer monitors - especially in smaller sizes. These panels have very good response times (2ms to 5ms) - so are well-suited for games with a lot of motion.






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






7. Screen size is often expressed in two different measures - the ____ screen size (also called the actual size) and the ____ viewing size that identifies the largest image size that can be displayed.






8. A ____ screen is typically desired for watching movies - or on laptops where the screen is viewed in full sunlight.
