Digital viewer for presenting stereoscopic images as well as 3D video.
The viewing method is based on the side by side principe on one single or doubleLCD. A image splitter inside the viewer prevents crosstalk for the left and right eye. Most stereoscopic content is available in this format on the internet as well consumer (video) cameras. You can decide yourself the kind of source to connect to the viewer; laptop, desktop or media player. The viewer acts like a mini monitor with HDMI connector.
The graphics data to the viewer is simple and does not require a lot of processing power. This allows the source to be simple / small. One solution we provide is a pre configured Raspberry pi micro computer. A simple slide show with side by side images is enought.

LIMITED WARRANTY:
The LCD(s) in the viewers are made for smartphones and VR viewers, consumer electronics. However, the active usage time in the viewer is considerably longer than with mentioned applications. The environmental conditions might differ as well. The life span of the LCD might be limmited.
In the unlikely event that the LCD breaks, outside of improper use, within a year, a new LCD set will be made available free of charge, with the request to return the old one.
When the LCD fails after 1 year of purchase, whether it is the first or already a renewed LCD set, we charge LCD replacement costs when returning the old set. These replacement costs are lower than a complete set. The height depends on the type of LCD (s).
Known Issues:
When the viewer is connected to Apple products with Apple Silicon hardware, MacOS forces YCbCr colors instead of RGB, resulting in a strong pink tint across the entire image. Tools such as BetterDisplay can remedy this.
When the viewer is connected to Brightsign, it may decide to output YCbCr colours instead of the required RGB, resulting in strong pink and green tints across the entire screen. A possible solution to this is to manually set the resolution, as well as the colour space, instead of automatic detection.
