Carefully choose the "most correct" answer, if there appears to be more than one !
* The high voltage at the CRT Anode for a monochrome monitor should be approximately
- 10,000 volts per square inch
- 1 KV per diagonal inch
- 1500 volts per diagonal inch
* The high voltage at the CRT Anode for a color monitor should be approximately
- 10,000 volts per square inch
- 1KV per diagonal inch
- 1500 volts per diagonal inch
* An advantage of "VGA" Monitors is that they
- Can have more colors than the "EGA" Monitors
- Have better pixel definition than "EGA" Monitors
- Are brighter than "EGA" Monitors
- Both 1 & 2 are correct
* The advantage of "EGA" Monitors is that they
- Can have more colors than the "CGA" Monitors
- Have better pixel definition than "CGA" Monitors
- Are brighter than "CGA" Monitors
- Both 1 & 2 are correct
* Signals from the computer's video board to the video monitor
- Will be analog for CGA, EGA, & VGA
- Will be TTL for CGA, EGA, & VGA
- Will be TTL for CGA & EGA, but analog for VGA
- Will be TTL for the older CGA, but analog for the newer EGA & VGA
* The advantage of "XGA" or "SVGA" Monitor Systems over "VGA" is that they
- Can have more colors than the "VGA" Monitor Systems
- Have better pixel definition than "VGA" Monitor Systems
- Are brighter than "VGA" Monitor Systems
- Both 1 & 2 are correct
* The "Brightness-Control"
- Only affects the background
- Affects the background and the character brightness
- Only affects the character brightness
- Only affects the cursor brightness
* The "CGA" Monitor
- Is for colored text only (no graphics).
- Requires analog input signals
- Cannot utilize interlaced TTL input signals
- Is simply a TTL version of the "RGB" Monitor
* The advantage of a "VGA" Monitor over a "EGA" Monitor
- Is greater definition, or resolution
- Allows more colors
- Can utilize both TTL and analog input signals
- Requires less CRT voltage
* "Dot-Pitch" refers to
- The maximum spacing allowed between pixels by the "Dot-Clock"
- The "Merging of the Dots", caused by the electron beams striking the CRT face
- The angle, or pitch of the dots
- The spacing between the dots on the CRT faceplate
* The composition of horizontal and vertical scans create a white screen on the CRT called
- The "Composite-Video"
- The "Raster"
- The "Frame"
- The "Field"
* The expected amount of high-voltage on a monitor should be
- Approximately 1KV per diagonal inch for a color monitor
- Approximately 1.5KV per horizontal inch for a color monitor
- Approximately 1 KV per diagonal inch for a monochrome monitor
- Approximately 1 KV per horizontal inch for a monochrome monitor
* The coil of wire that runs around the circumference of a color CRT
- Is there to secure the CRT against vibration or movement
- Will slightly degauss the CRT each time it is turned on
- Should be normally conducting continuously during normal operation
- Is normally turned on by the "Thermister" for degaussing the CRT, after warm-up
* The advantage of a SVGA or XGA video system over a VGA is principally
- It allows for more colors than the VGA system can possibly produce
- It allows for more definition and colors than the normal VGA
- As a new technology "Green Machine" it consumes less power
- As a new technology "Green Machine" it can turn down or off automatically when not in use
* The advantage of a SVGA or XGA video system over a VGA is principally
- It allows for more colors than the VGA system can possibly produce
- It allows for more definition and colors than the normal VGA
- As a new technology "Green Machine" it consumes less power
- As a new technology "Green Machine" it can turn down or off automatically when not in use
* In a video monitor, the horizontal-driver transistor(s) would nearly always be found near the __________________________.
* In a video monitor, the observation of a chip with a pair of heat-sink "wings" is most likely the __________________________.
* The appearance of 3 identical sets of circuitry in a video monitor, is obviously the ___________________ circuits.
* While making observations with an oscilloscope near the flyback-transformer of a color monitor, if the signals are a higher frequency than 15,750 Khz, the conclusion would be that the monitor is probably a ______ or ______ type, rather than than a ______ type.
