  • PC - End-of-life:  The devices provides miserable and frustrating performance.  Parts are not available and device is not serviceable.  Typically the computer is 10+ years old.
    • Action:  Device is allowed to run “as is”.  It will not be serviced, moved, or re-imaged – it will be removed if service of any type is required.
    • Suggestion:  Replace now. 
  • E-Waste:  The device is no longer capable of operating on the district’s infrastructure, and cannot be upgraded to do so.
    • Action:  Device is removed and recycled.
(*) Windows 7 extended support ends in January of 2020. After that, all systems must be on fully-patched Windows 10 to remain on our network.
(**) Dell Optiplex 780: Microsoft does not support the year-2010 tech in the 780s for Windows 10. As such, it is unlikely that 780s can remain on our network after January of 2020.


Tech Refresh:  The dedicated "PC tech refresh" board allocation ended with school year 2017/18 and was replaced with "mini-grants" through the Curriculum department. The Schools are again fully in charge of their own tech budgets.

If a school wishes to purchase additional PCs for use as classroom student devices, it may do so through the district's technology purchase process. Please see below for example pricing.

Display Comparison

The following identifies the general differences between Commercial and Consumer type displays.





Commercially rated usually with multi year on-site for LCD & plasma. When consumer displays are used in a commercial environment, the warranty usually reverts to 90 days over the counter requiring the display to be shipped back or taken in to a service center for repair.

Burn-in & Image Retention Technology

Features extensive advanced anti burn-in and image-retention features Only standard features.

Public Display Security Features

Usually incorporates measures to protect controls in a public environment including locking of front panel and IR remote. No control locking


Typically include VESA compliant standard mounting connections to complement standard industry mounting devices.
Not all consumer products are VESA compliant. May need special optional mounting brackets. Third party mount compatibility is questionable.

Landscape and Portrait Display Orientation

Most models built to do both landscape and portrait modes. Portrait modes are typically not available with consumer grade models.

Heat – Operating Hours

Designed to withstand long operating hours with thermal characteristics built in the internal design for proper heat dissipation in both portrait and landscape modes. Commercial plasma displays typically incorporates additional fans to dissipate heat. Designed for limited time operation with the intent of long off times. Not appropriate for 24-hour use.

Compatibility with PCs

Designed specifically for compatibility with PCs and AV standards. Designed for compatibility regarding TV/video but can support PC usage.

Backlight & Grayscale

Most will produce a full grayscale with good linear color tracking from black to white showing all 255 different levels of luminance (brightness). This is recommended for the diversity of PC applications. Grayscale is skewed for more of the bright white end of the grayscale producing more vivid saturated color associated with TV/ Video motion.

Internal Scalier/Algorithm

Most models recognize all PC resolutions including wide formats and different refresh rates (1024X768@ 60, 72, 75, and 85HX) in addition to TV/video resolutions.
Most are designed specifically for TV/video formats with very limited PC resolutions.

Connector Interface

Most models Include standard RS232 external control/ connector, PC and video loop-through connector capability regarding multiple display configurations from a signal PC or video source, and industrial BNC locking connectors.
Most do not offer external display control/connector, video loop through capability or multiple display configuration capability. Do not offer BNC connectors.
