43” iiyama ProLite LE4340S-B3 Professional Display, Full HD VA, USB Media, 16/7

iiyama ProLite LE4340S-B3 is a 43″ Full HD professional display, designed for digital signage, retail, conference rooms, exhibitions, POS/POI, control rooms and production spaces. The screen uses a commercial-grade VA panel, with LED backlighting and a fanless design, offering reliable and quiet operation in 16/7 mode, ideal for intensive use.

The VA panel offers high native contrast of 3000:1, deeper blacks and more saturated colors compared to TN panels, while maintaining wide viewing angles 178°/178° viewing angle. This means that content remains clear and legible even when viewed from the side – a major advantage in public spaces where the audience is constantly on the move.

The 1920 x 1080 (Full HD) resolution on the 43″ (108 cm) diagonal, combined with 350 cd/m² brightness and mild matte (haze 2%) treatment, ensures clear images, easy-to-read text and good visibility in bright indoor environments. The viewable size of approx. 941 x 529 mm and the thin bezel (12 mm side and top, 15 mm bottom) provide a strong presence of the content, not the frame.
