It divides viewers into three distinct categories based on their
distance from the display versus the height of the display

Student should sit no further than 5 metres from the screen

Analytical Viewing - Viewers are fully engaged with the content and can make critical decisions by the ability to analyse details within the displayed image

Basic Viewing - Viewers are actively engaged with the content and can make basic decisions from the displayed image

Passive Viewing - Viewers are passively engaged with the content and able to recognize what the images are on a screen and understand the general intent of the displayed image

Definitions are from DISCAS (Display Image Size for 2D Content in Audio visual Systems); released in 2016 by InfoComm International - association representing the commercial audio visual industry worldwide.

When you are looking for a bigger display, projection is the obvious answer. With most of Epson projectors being able to project up to 300" - that means a brighter and clearer picture for everyone in the room. Most importantly, it ensures that your information is conveyed accurately and your audience captivated by the content that is displayed.

Flat Panel Readability Test FAQs

Who did the research?
The independent, quantitative study was conducted by Radius Research in multiple U.S. markets.

What flat panel was used?
Sony 4k Ultra HD model - #1 selling 70-inch flat panel (Based on USA market share data)

How many students were tested?
106 students ages 12-22. Radius determined the sample size needed for this study.

How big was the room, and how far away were the students?
The room was about 30'x30', and there were 30 seats in a traditional classroom layout (5 rows, 6 seats/row). The first row started about 8' from the display, and the back of the last row was about 27' from the display.

What was shown to them and how big was the text?
Students were shown basic content - a simple text table, Excel spreadsheet and PowerPoint schematic - then asked to find data (a word, short phrase, or number) and copy it down. Size of text varied from large headlines to smaller details.

Which seats were the worst?
The sample size for each eat is not large enough to substantiate "can't read" statement for a particular location or distance, but the error rate of respondents in the back rows was significantly higher than in the front rows.
