At ProjectorsOK we wanted to test the Nec from the professional Performance Advanced series, installation projectors that can be configured very easily and economically in Edge Blending , to make a Video Wall with projectors .

Edge Blending is a system that allows you to use several projectors at the same time to generate a much brighter and high definition image on a budget. It also allows to generate an elongated projection, with image formats other than 4: 3 or 16: 9, concatenating several projectors by placing them side by side or one on top of the other.

In this case, with 2 XGA projectors of 5,000 lumens Nec PA500X, placed side by side, we get 10,000 lumens and a resolution equivalent to Full HD.

Calibration of these projectors in Edge Blending is done automatically, substantially reducing installation and adjustment time. For them to work together, we only have to connect the two projectors in a network, and run the calibration program from a computer with a webcam. The automatic process takes a few minutes and thanks to it we will achieve a single image perfectly superimposed and without noticing that it is made up of several projectors.

Connections The new range of Nec PA500X offers a wide range of connections, including on all HDMI and DisplayPort models. Through an optional module they also have a wireless WiFi connection.

Interchangeable Optics This Nec range has a wide range of interchangeable lenses, to perfectly adapt to the needs of each installation:
