Do the test patterns do it too. (oops, 1 test pattern:)
THere is a modification for this I believe, not sure if it's documented here though. It should be in the archives in the avsforum though.

i still seem to remember doing something in the past that brought this "split screen" look into effect before, and was able to turn it off. no luck this time yet.....

Turn up the contrast perhaps? Or adjust pots R1 and R5 on the waveform generator board.

pulled NEC scan converter out of line, replaced with runco branded converter that's exactly the same, problem solved. might have been a bad bnc cable connection, will swap them back tomorrow to check.
night all!

Good to hear you solved it 
Interesting tidbit about this fix though. My 4500 will only display the 1/2 bright image when no source is on, otherwise I see this and my card isn't modded:
