Of the following resolutions used in Windows, which provides a 16:9 aspect ratio signal for use with widescreen monitors?
  1. WXGA
  2. SXGA+
  3. UXGA
  4. WUXGA
Explanation
Answer: A - WXGA (Widescreen Extended Graphics Array) provides a 16:9 signal for use with widescreen monitors.

Key Takeaway - SXGA+ and UXGA both provide 4:3 aspect ratios (full screen) and WUXGA (Widescreen Ultra Extended Graphics Array) give an even wider 8:5 aspect ratio. WXGA is the only resolution listed that provides a 16:9, widescreen aspect ratio. These differences are important to know for choosing the right resolution for the right monitor.
