Akira ALM55Z3

Led by the explosion of digital signage applications, the professional large-screen video-monitor industry has expanded the capabilities and reliability of these devices through diagnostics, auto-sensing, increasing temperature-operating ranges, and keeping a broad selection of input ports. Many included here also feature video and control signal-loop-through ports for videowall applications. Our current roundup in this field highlights these new capabilities, and it should serve to demonstrate the technical trends in the large-screen professional monitor market.

Akira designed the 55in. ALM55Z3 with a slim bezel width of 5.3mm and four DVI input ports—each of which loops through to its corresponding DVI output—for public displays operating continuously and for easy configuration into multi-monitor setups and videowalls. RS-232 also loops through for daisy-chained serial control in videowalls up to 99x99 units. The newest model in the ALM series, the LED-backlit ALM55Z3 also has a removable electronic compartment for easy servicing and separate installation of the electronics and the LCD panel. The monitor provides 1920x1200 screen resolution with a brightness figure of 700cd/m².
