Of the Olevia's two color-temperature selections, the 6500 mode proved to be the more accurate. Grayscale tracking was ±652 degrees K of the 6,500-K standard from 20 to 100 IRE - below average performance. The set has no user-menu settings for adjusting white balance, and its service-menu adjustments only apply to the component-video inputs. Color-decoder tests showed no errors for both the TV's HDMI and component-video connections. Compared with the SMPTE HD specification, the set's measured red color point indicated a fairly high oversaturation, while its green point showed a bluish bias.

Overscan - the amount of picture area cut off at the edges of the TV's screen - measured 0% for 1080i/p-format high-definition signals with the Screen Crop mode switched to the Off setting. The set displayed 1080i/p and 720p test patterns at full resolution for both HDMI and component-video connections, although slight edge enhancement was visible on the HDMI input. Screen uniformity was fair, with picture contrast falling off substantially at off-axis angles beyond 15º. There was also a slight amount of screen clouding visible on gray full-field test patterns, as well as on regular program material - particularly, video images with large patches of white.

The Olevia failed the film-resolution test on the Silicon Optix HQV high-def test disc, and jaggy picture artifacts were occasionally visible on 1080i-format movies that I watched. Upconversion of standard DVDs proved to be average, although the set's Video Noise Reduction settings weren't very effective at removing noise and grain from less than pristine pictures.
