49.3: Very‐High‐Resolution Displays: Productivity Gains in Word‐Processing and Spreadsheet Tasks

Abstract

We tested the impact of very high vs. high spatial resolution (∼200 vs ∼100 dpi) displays on user performance for common computer tasks such as text editing and spreadsheet use. We found advantages for the very high resolution display and for LCDs over CRTs.

Effect of display resolution and antialiasing on the discrimination of simulated-aircraft orientation

“…However, there was again no direct measurement of spatial resolution that would allow the results to be compared to those of other studies. Many other studies concerned with both engineering and perceptual issues may be cited in this context [2,[6][7][8]. Thus, although the importance of specifying display resolution is often recognized, it is not consistently measured, and there appears to be no generally accepted procedure for specifying it in the context of applied visual and perceptual research.…”
