Solved Potential simple solution for Wii to VGA?

480i RGB does indeed give you a cleaner picture than 480i composite, but the real significant improvement for LCD screens comes from progressive video. I would think it would be pretty hard to find a screen that accepts interlaced 50hz RGB video, seeing as the only way to know if it accepts it or not would be to buy it and test.

Yea, the screen I have that accepts it is a 7 year old 5" Dalian Good display. Which would be fine, if I wasn't trying to keep the screen down to 3.5" to keep the portable I'm building to roughly the size of a Gameboy.

Im with pineapples on the stance about the YPbPr to VGA solution. When that chip is implemented correctly, there is no loss in quality or latency. However, we have yet to find a single product that has a complete and proper circuit for that chip. That's why everybody, (including me) has said that YPbPr to VGA converters are crap: because all the ones available now are not properly designed.

Yup, I am positive that it is my boards. I've had these since 2012 and they came from those cheap PS2/3/Wii to VGA cables. It's a shame about the poor implementation of the LMH1251.

@Redmagnusx. Are you using the Mayflash cable version or the box version? IIRC, the cable version has two revisions and has been known to have video quality issues. Maybe @ttsgeb can comment on the quality since he seems to have experience with the 2nd revision cable as documented in the ModRetro thread.

It's the cable version that I purchased back in 2012. I'm sure you are absolutely correct about it being the board given the age and the picture quality I am seeing. Which stinks because it'd be a decent option for a portable along with implementing a composite switch, which is what I did in my portable Gamecubes. I'm psyched for the BBVideo, I just don't think that it will be out in time for me to meet my deadline.

Yup thats the one I got, which is the same one pictured. They really cheaped out on the circuit, which is why it's so terrible.

It's a bit of a pain in the ass to work with, but it was effective enough at getting VGA out of unmodded xboxen. Gotta make sure your wires are real nice and you have an extremely clean +5v source for it unless you want annoying diagonal lines across your screen.
If/when I go at it again, I'd probably just go through the effort of making sure I'm implementing things proper-like, rather than just bubblegumming it all together and hoping for the best.
