Thread: Setup 640x480 30Hz Output on DVI-I

i have nvidia gf210 card available dvi-i converting component cable old crt television (yes know)

know television has display capability of ntsc 480i nvidia server x not allow me select other 60hz output (which guess progressive).

can modify xorg.conf in way force interlacing on screen or hardware not allowing interlaced output?

have tried adding flag interlacing.

the config file may have multiple monitor sections. there should @ least one, monitor being used, default configuration created when 1 isn't specified.monitor sections have following format:

section "monitor" identifier "name" entries ...endsection

the mandatory entry in monitor section identifier entry.
identifier entry specifies unique name monitor. monitor section provides information specifications of monitor, monitor-specific options, , information video modes use monitor. specifying video modes optional because server has built-in list of vesa standard modes. when modes specified explicitly in monitor section (with modes, modeline, or usemodes keywords), built-in modes same names not included. built-in modes different names are, however, still implicitly included.
entries may used in monitor sections described below.
......flags "flag" ...specifies optional set of mode flags, each of separate string in double quotes. "interlace" indicates mode interlaced. "doublescan" indicates mode each scanline doubled. "+hsync" , "-hsync" can used select polarity of hsync signal. "+vsync" , "-vsync" can used select polarity of vsync signal. "composite" can used specify composite sync on hardware supported. additionally, on hardware, "+csync"and "-csync" may used select composite sync polarity........
