The external graphics is in PDF, which is attached to the original

question about it. When inserted into LyX, maybe LyX creates a
temporary bitmap or PNG file to show to the user, I am not sure.
I opened the PDF file in both ImageMagick and IrfanView and inspected
the image properties. IrfanView reports it as 96x96 DPI, 474 x 234
pixels. ImageMagick reports it as PNG format with the same resolution
and geometry. Note that this is entirely outside LyX.
Maybe these programs convert PDF to a bitmap? At least for ImageMagick
this seems highly likely. Try to open the PDF in a proper PDF viewer and
zoom in. It is definitely not 474 x 234 pixels.
