No scan doubling, no scaling, no external power. The ST's native timings are preserved, so the picture looks the way the hardware always meant to look.

The Enhanced version adds an active RGB amplifier, analog low-pass filtering and buffered outputs, so it is better suited for early Atari ST boards, machines with weak or noisy signals, jailbar-prone hardware and long-cable setups.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the ST2VGA Enhanced useful for very early Atari ST machines?\u003c\/strong\u003e\u003cbr\u003e\nYes.

The buffered output isolates the RGB lines from the monitor input, and the filtering removes the high-frequency components that show up as the vertical bar pattern on modern LCDs. In the most extreme cases the artifact is heavily reduced rather than eliminated, but the picture is always noticeably cleaner than with a passive adapter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does the Enhanced version need external power?\u003c\/strong\u003e\u003cbr\u003e\nThe integrated video amplifier and buffering stage need a stable 5 V supply to operate correctly.
