The panel is not the issue, the graphics hardware is.

Generally: Yes - if we're talking analog (VGA or DVI-A). If the graphics 
hardware you're working with allows ModeLines, no problem. NEC manuals 
are very detailed, so you will find the required timing there.

However, most hardware won't accept resolutions which aren't a multiple 
of 8 (or 16). The NEC panels I know (42MPx/50MPx/61MPx, xxxVP4 and 
possibly xxxXM1) support 1360x768 and/or 1376x768 anyway. But be aware 
that some modes require manual changes via the panel's OSD menu to be 
recognized; for example, 1376x768 requires RGB mode "wide1" for NEC 
panels; these panels won't accept 1360x768 via DVI-D. For a detailed 
mode list, see the panel's manual.)

As for digitally connected plasma panels (via DVI-D) in general, I don't 
really know, but I would guess that most drivers that support digital 
output and ModeLines would not cause any trouble.

(Besides, the "sis" driver has a small built-in database for some plasma 
panels [NEC, Pioneer and Panasonic], so no ModeLine is required for 
digital or analog output. Just add the desired mode [XxY] to your 
Screen/Display section.)
