What first caught my eye by Televes H45 Spectrum Analyzer was the HDMI port feeding a flatscreen television. How cool is that?

The picture was on a high resolution display, not the low quality displays I've seen in the past, so tiling or macro-blocking would be apparent to the user. See the picture below:
