31.5-inch 4K VA monitor for colour-critical work
The 31.5-inch LG 32BN50U-B delivers 3840 x 2160 resolution on a VA panel with 3000:1 contrast and 1.07 billion colours. DCI-P3 coverage reaches 90 percent typical, and HDR10 support adds highlight detail for creative review. AMD FreeSync and a 60 Hz refresh rate keep motion smooth for casual gaming. The tilt-adjustable stand moves from minus five to plus fifteen degrees and the unit is 100 x 100 mm VESA mountable.
Typical power draw and quiet operation
Typical consumption is rated at 45 W, rising to a maximum of 55 W under full brightness. Energy Star measured draw is 30.75 W, while sleep mode drops to 0.5 W and DC-off stays below 0.3 W. The monitor runs on 100 to 240 VAC at 50 or 60 Hz with no external brick. Built-in MAXXAUDIO speakers provide desktop sound without extra hardware or fan noise.
Steady output during long sessions
The VA panel maintains 350 cd/m² brightness and 178-degree viewing angles across extended use, so colour and contrast do not shift when viewed off-centre. A 4 ms response time limits ghosting in moving content, while Dynamic Action Sync and Black Stabilizer preserve visibility in dark scenes. FreeSync continues to match frame pacing at 60 Hz without stutter, making the display reliable for all-day productivity or media playback.

Preguntas sobre este artículo
How do I attach the 31.5" 4K monitor to the included stand without stripping the screws?
Align the stand neck with the rear mounting bracket, then tighten the captive thumbscrews by hand until snug; the step most people miss is seating the neck fully before turning the screws, otherwise the threads cross.
What part will need replacement first on the LG 32BN50U-B after several years of daily use?
The internal LED backlight is rated for tens of thousands of hours; when brightness eventually drops below the 350 cd/m2 spec, the whole panel assembly is the serviceable unit.
At what point does the VA panel hit its contrast limit during a long HDR10 session?
The 3000:1 static contrast ratio holds until the panel reaches its thermal steady state; after that, local dimming cannot deepen blacks further because the monitor lacks zone dimming.
