What is the difference between “Quadlet”, “Bilinear”, and “Hexlet” display modes?
“Quadlet” display mode is a low-cpu usage display mode that quickly demosaics the image using every 2×2 square of pixels to create one RGB pixel. As a result, quadlet mode actually only had 1/4 the resolution of the original image. For instance, a 1920×1080 input RAW data source will demosaic to 960×540. SiliconDVR will automatically scale this resolution in the display for the output resolution desired, but realize that even though you may be outputting 1920×1080 on the external monitor, the actual resolution of the image is only 960×540. “Bilinear” is a cpu-intensive demosaic algorithm that interpolates the RAW image data and outputs a 1:1 resolution image from the input source data. 2K or 1920×1080 RAW input data outputs as 2K or 1920×1080 RGB data. As a result, bilinear interpolation is adequate for full-resolution monitoring when per-pixel image accuracy is desired on the video-village viewing monitor, or broadcast, large-venue display, or tape-backup applications. “Hexlet” is a l
