Help choose correct HDMI GPU resolution to get standard PAL/NTSC signal Hi im trying to go from computer's ATI GPU via hdmi->component_adapter to SD DVB-T Modulator.

According to modulator spec it does 720x576_50i (PAL) &amp; 720x480_60i (NTSC)

Which if any of these control panel resolution choices would match either or those: (ive reduced the list to the ones i think are closest)


720 by 576 (16bit) 50 Hertz
720 by 576 (16bit) 25 Hertz (Interlaced)
720 by 480 (16bit) 60 Hertz
720 by 480 (16bit) 30 Hertz (Interlaced)


And finally how would any of these compare to the outputs from a Decklink Mini Monitor, that states it does SD 625/25 PAL, 525/29.97 NTSC.

Thank you.
Out of your list, these look like your acceptable modes


  720 by 576 (16bit) 25 Hertz (Interlaced)
  
  720 by 480 (16bit) 30 Hertz (Interlaced)


Although depending on your adapter, it may be able to work with the other two as well. Note that all the modes are 16-bit so you are working with much reduced color resolution.

The Decklink modes are PAL and NTSC spec signal outputs and, I suspect, it will automatically downscale and crop your full resolution HDMI feed, so no need to tinker with your computer display modes.
