Off-axis Color Performance “Surprisingly Poor” in Top LCD Displays (http://displaydaily.com/2008/11/17/off-axis-color-performance-%e2%80%9csurprisingly-poor%e2%80%9d-in-top-lcd-displays/)

Excerpts:
"a new report reveals unexpectedly poor results for even "flagship" LCD display models. According to a recently released report jointly produced by DisplayMate Technologies and Insight Media, the level of off-axis color inaccuracy–and its worsening with wide color gamut displays–was a surprise even to experts that observed the test results."
"In an interview this weekend with Dr. Soneira, he said that, "The chromaticity shift with angle is objectionable even at ±10 degrees for all of the tested LCDs. Everyone that came to see the shoot–out-including industry experts, manufacturers, engineers, reviewers, journalists and ISF instructors–were shocked at how strong the effect is. Everyone knew there was an effect, but the side-by-side comparison shows how incredibly large it actually is. Even when viewers are seated close together side-by-side, each person will see a different picture with noticeably different coloration on an LCD."
"Eight HDTV LCD displays were used in the study, representing five major CE manufacturers (additional plasma monitors were used as references). Also, three of the LCD displays were rated as "flagship" top-of-the line sets. Nonetheless, all the LCDs showed large viewing-angle artifacts, according to the report, with noticeably different coloration in both hue and saturation, as well as variations in contrast and black level. With pure saturated colors, all of the LCDs produced a noticeable color shift at 15 degrees, whereas the performance of the plasma displays was visually indistinguishable from face-on viewing to well beyond 45 degrees."
