With a 55" diagonal, 4K Ultra HD resolution (3840 × 2160 px) and VA panel technology, it offers exceptionally sharp images with true colors and a high contrast of 5000:1, which ensures great visibility even in brightly lit areas. 400 cd/m² brightness provides sufficient performance for various applications, whether security systems, presentations or video walls. In addition, the monitor is certified for 24/7 operation with a long lifespan of 30,000 hours**, which guarantees reliability even with intensive use.

Sharp image and modern design

Thanks to DLED backlight technology and 72% NTSC color space coverage, you get vivid and accurate colors, ideal for professional applications where image quality is key. Ultra-thin bezels (only 1.1 mm) on three sides and more than 95% screen-to-body ratio give the monitor an elegant look, making it ideal for creating seamless video walls or as a standalone device. 178° viewing angles (H/V) ensure consistent image quality regardless of the viewing angle.

Connectivity and compatibility

The monitor is equipped with a wide range of inputs for maximum flexibility. Two HDMI 2.0 ports enable image transmission in full 4K resolution at 60 Hz, while the VGA port ensures compatibility with older devices. Two USB 2.0 ports are ideal for connecting peripherals, and the RS-232 port offers the possibility of remote control and integration into complex security systems. Built-in stereo speakers (2× 10 W) guarantee quality sound without the need for additional devices.

Comfort and eye protection

Long-term viewing is comfortable and less taxing on the eyes thanks to Flicker-free technology and blue light protection. Fast response time of 6.5 ms eliminates motion blur, which you will especially appreciate when watching dynamic content such as security footage or presentations.
