That green bar has been seen before, some kind of shadow image of horizontal blanking. I can't remember if there was a solution for this, but there was definitely a thread about it before (but I can't find it at the moment).

DRW: That's about CRT. This appears to be a modern TV whose deinterlacer is doing this because it expects a frame that's 262.5 lines long instead of 262.

Retro consoles produce an NTSC-compatible signal with slightly nonstandard scanline length and field length. The size of the field incluing blanking varies from one picture generator to another. Measured in color subcarrier cycles, the field sizes are as follows:

  • Atari 2600, Atari 7800, Apple II, Master System, and Genesis: 228x262. Color artifacts line up vertically.
  • NES and Super NES: 227.333x262. Color artifacts line up diagonally.
  • Neo Geo: 227.5x262. Static dot pattern.
  • Fifth generation consoles (PlayStation, N64): Haven't tested
  • Sixth generation (Dreamcast and later): 227.5x262.5. This timing follows the NTSC standard.

Does the problem happen when you connect the same NES Control Deck to a traditional CRT SDTV?

I only have an LCD, if I had a CRT I would use the NES on it.

You said you "The adapter needs to be plugged in but I haven't tried it unplugged". How did that go?

Does the HDMI adapter have an RF or A/V input? Do you have another cable for whichever connection you're using? Have you tried it?

Does the HDMI adapter have an S-video input?
