The NES draws exactly 262 scanlines. (Hence why its vertical refresh frequency is 60.1 Hz instead of 59.9 Hz)

In any case, the so-called "240p" signal has timing compatible with the actual 240p RGB signals used by Apple IIGS RGB monitors and standard-resolution arcade monitors.

Yeah, it's actually the monitor's responsibility to deal with the sync signals given by the source. That's why they're there. :P As long as there isn't a significant amount of deviation from the standard, any monitor will be able to display the picture. That's not to say there aren't monitors that will handle a super-wrong signal, though.

Given the extent to which the output of a VCR does NOT comply with NTSC, you can be reasonably assured that ALL SDTV CRTs can deal with 240p and 480i properly. (More information, and I found this a very interesting read: http://www.ronaldsnoeck.com/vcr.htm )

HDTVs with their "motion interpolation" and "upscan conversion" and trying to put lipstick on the pig, well... only comes close to working when the pig complies.
