Quality Tests: Samsung BX2350

CCFL Versus LED: Is There A Downside To Going Green?

Samsung’s LED-based BX2350 was an odd bird at the beginning, arriving with a strangely sensible brightness of 50, a 75 contrast, and color levels of R50/G50/B50. This provided a downright moderate luminance of 150.2 cd/m2 with a 0.2 cd/m2 minumum. Unfortunately, the temperature was way off, swinging far into the red at 7200K.

During calibration, we found the red channel very difficult to move. To get the desired 6500K, we had to force the red up even higher to 73 and both the green and blue down to 32. Arriving at a 120.2 cd/m2 luminance needed knocking the brightness down to 39. You can see just how skewed the red channel is in our post-calibration readout.

Perhaps not surprisingly, we had a fairly wide temperature range across the screen following calibration, with a low of 6200K (top-center) and a high of 7000K (bottom-center). Fortunately, the luminance variance was much better—actually one of the best in this roundup. Values ranging from 109.4 to 125.1 were downright even and dependable. Score one for the LED.

The BX2350 nabs our group’s highest calibrated gamut volume: 949 526. This is interesting, because even though we had a heavily weighted red channel, it’s the yellows and greens that blow way past sRGB’s profile attributes.

On Delta-E, the Samsung LED performs fairly well. We see one gray tone pop out to 2.17, but otherwise the results seem fairly normal, with the navy blue spiking to 4.11 and our overall average hitting 1.41.
