This is a JVC 56WP84. It is a CRT RPTV that I bought in early 2004.
According to nvidia-settings the native resolution is 1920x1080. I
don't know that a 'native resolution' makes much sense on a CRT RPTV
since it can do any number of resolutions. But I may not understand
the phrase entirely.
nvidia-settings thinks it is a DFP.
