abstract = "AIM: The aim of this study was to determine if there is a significant difference between the detection of low-contrast objects on 1MP review monitor and 3MP primary monitor. METHOD: The monitors compared were a 1MP NEC Multisync 1980SXi and a 3MP Barco Coronis MFGD 3420. The low-contrast detectability of these monitors was compared at a high ambient light setting (73 lx) equivalent to that of a ward or intensive care unit in the clinical setting and a low setting (20 lx) which reflected that used in reporting rooms in standard practice. The comparison was made using a CDRAD test tool and visualisation of nasogastric tubes and a central line. RESULTS: Image quality results for both the psychophysical and diagnostic performance test were substantially higher for the 3MP monitor than those obtained for the 1MP. Significant differences p≤0.000 existed between the IQF results for the 2 monitors. Image quality results were higher at the lower ambient light setting for both monitors. CONCLUSION: Contrast visualisation is significantly improved through the use of primary monitors. Review monitors are adequate for the visualisation of lines an NG tubes in low and high light settings.",
