With the Movie picture and Warm2 color-temperature presets selected, the Samsung LN-T5265F's grayscale displayed a blue bias, tracking approximately +900 degrees kelvin of the 6,500-K standard from 30 to 100 IRE. Adjustments made to the red, green, and blue controls in the White Balance menu resulted in ±362-K tracking from 30 to 100 IRE — average performance for a flat-panel LCD. The set's red, green, and blue color points all showed fairly significant levels of oversaturation compared with the SMPTE HD specification for digital TV. Color-decoder tests also revealed a severe –25% green error, as well as a –5% red error, on the HDMI inputs. For the component-video connections, color-decoder error was –15% red and –7.5% green.

Overscan — the amount of picture area cut off at the edges of the TV's screen — measured 0% in Just Scan mode when showing high-definition signals and 5% in 16:9 mode (a bit more than the 3% average for similar modes in other HDTVs). The set displayed 1080p and 720p test patterns very cleanly and with full resolution via its HDMI connections, but the same patterns looked slightly softer when delivered in 1080i format. On the component-video inputs, both 1080i and 720p patterns looked slightly soft and displayed a degree of moiré. When I viewed the set either head-on or from off-center seats, screen uniformity was mostly very good. Low-level full-field test patterns (30 IRE and under) looked darker at the edges than at the screen's center, however, an effect that was occasionally visible on regular programs.

The LN-T5265F had no problem with 2:3 pulldown processing when displaying regular movies on DVD, but it failed the video- and film-mode deinterlacing tests on Silicon Optix's HQV high-def test disc. Its various noise-reduction settings helped to clean up grainy images with only a limited sacrifice of picture detail.
