Monitor Pixel Position Reader - Real Time Output

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of a device that can read the positions of specific pixels on a monitor and provide real-time output. The scope includes potential devices, methods of reading pixel data, and software solutions.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions the existence of such a device, expressing uncertainty about its availability.
  • Another participant suggests various interpretations of what "device" could mean, including reading light from the display, accessing data from the video port, or using software to fetch video memory.
  • A further inquiry asks for clarification on what is meant by "read" and "output," indicating a need for more specific definitions.
  • It is mentioned that there is QA testing software capable of recording and comparing entire screens down to the pixel level.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the existence or definition of a device that meets the initial query, with multiple interpretations and uncertainties expressed.

Contextual Notes

There are limitations regarding the definitions of "device," "read," and "output," which remain unresolved in the discussion.

Is there a device that can read the positions of pixels on a monitor, may be just 6 key positions
and give a real time output?

don't think have it.. or maybe just I don't know about it

Not sure what you mean by device.
Read the light off the display screen? (They used to have light pens. Obsolete now.)
Read the data off the video port? (Any flat screen monitor does this conversion to digital)
Fetch the video memory into another program? (software)

Yeah, can you be more specific? what do you mean by "read" and what do you mean by output?

There is QA testing software that can record and compare entire screens down to the pixel.
