ASSESSMENT OF A CRT DISPLAY SYSTEM

The use of cathode ray tube (CRT) monitors and graphics cards for the display of pictorial images is common. Certain applications require th e characteristics of the display device or medium to be accurately und erstood. One such application is the use of CRT based displays in expe riments involving subjective analysis of viewed images. In this paper we describe a series of experiments performed to characterize a displa y device used in our laboratories prior to its use in a subjective ass essment experiment. The tone reproduction characteristics are studied using transfer functions and gamma. Color reproduction is studied in t emporal and spatial dimensions. Finally, spatial effects are character ized by use of modulation transfer function (MTF) analysis.
