| 1. | Placement at the top or bottom of the disk gives horizontal scan lines.
|
| 2. | The required horizontal scan frequency for the Tandy 2000 is 26.4 kHz.
|
| 3. | Ancillary data can be located in non-picture portions of horizontal scan lines.
|
| 4. | The increased resolution over D1 comes as a result of a longer horizontal scan.
|
| 5. | The low level interface of input / display enable, horizontal scan direction and vertical scan direction signals.
|
| 6. | Vertical retrace is comparatively slow, occurring over a span of time required for several tens of horizontal scans.
|
| 7. | A resonant circuit is commonly employed, restricting the allowable horizontal scan rates to one or more very narrow ranges.
|
| 8. | This rate can be increased with the ECS and AGA chipsets by using a video mode with higher horizontal scan rate.
|
| 9. | Thus the interfering frequency may lie far from the horizontal scan frequency . talk ) 13 : 24, 8 February 2010 ( UTC)
|
| 10. | While stand-alone LCD monitors generally accept a wide range of horizontal scan rates, the same is not true of the vertical scan rate.
