OLEVIA 237T FHD

  Overview Review Specifications Calibration  

 

Model: Olevia 237T FHD (full high definition)
Reviewer: Robert Wiley

Calibration: There are no preset picture setting options in the menu system for the Olevia 237T so the viewer will be using one custom setting. There is no fluid backlight adjustment. Rather, there is a room light adjustment option of bright, medium and dark. This setting changes the backlight output to brighten or darken the TV. Using the menu “wheel" is cumbersome. Strangely, there are no numerical values for picture setting options. Following are the approximated percentage settings to bring the Olevia close to D6500K optimized for peak performance. These calibrations are for a dark viewing room, so if your room light is normal to bright you will need to adjust the contrast and brightness settings up 15 to 20%:

Room Light: Medium
Color Temp: Warm
Brightness: 45%
Contrast: 68%
Color: 55%
Sharpness: 30%
Color Temp: D6500K
Tint: 50%
Noise Reduction: Medium

Contrast Ratio Measurement: The 237T’s contrast is listed at 1600:1 in the manual. With our checkerboard pattern test and post calibration we measured it at 256:1, which is very good for an LCD. During DVD viewing, the contrast ratio excellence of the Olevia was evident and helped colors pop. (Note: there was some light bleed in into the blacks in the lower left quadrant of the Olevia panel tested).
