The 503’s form factor is at home on mirrorless cameras and smaller cinema cameras, though it is equally effective on larger cameras as well. A unibody aluminum exterior keeps the monitor durable yet lightweight, while also acting as a heatsink for the internal electronics. Further adding protection, the LCD panel itself is topped with a layer of optically bonded Gorilla Glass, notable for its transparency and toughness. The optical bonding process ensures that blacks are not washed out while simultaneously reducing the harshness of reflections.
On the sides of the display are the SDI and HDMI I/O. Having dual SDI ports allows for A/B viewing of two different SDI signals, or the secondary port can be assigned as an output for sending an SDI signal downstream to another monitor, switcher, or wireless accessory. All the functionality of the monitor is available via the PageBuilder OS, which provides advanced functionality with a simple and efficient graphical user interface.
