S-ENC component modification seems too bright, but not sure about adding resistors...

    I've directly wired up the component output on an S-ENC SNES, but the resulting output seems a bit too bright, but I don't know if it may just be my monitor's component connection (I'm using a DELL 2410U). Just wanted to ask if this is common and whether I should install resistors on each line, as the colours appear to be uniformly bright.

    Here's a PBP of my component and composite connections (apologies about the flash):

    Admittedly the composite seems a bit too dark there, but I'd be looking for a happy medium between the two.

    Copied from Ace over on Sega 16:

    So from this it looks like you do need a resistor on the luminance line for the S-ENC encoder. 75 ohm to be exact. Hope this helps.

    I stuck a 75 ohm resistor on the luminance line from pin 23 of the S-ENC chip and it's a lot better now - just need to stick in some capacitors, as there are still some pretty noticeable jailbars. I would rather not use pin 7 from the AV port, as I'm considering getting an AD adapter which I'd like to hook up via the AV port while still having SNES component out.

    I strongly suggest you reconsider not using Pin 7 from the AV Out. Pulling Luma directly from the chip is not a good idea, as the signal is not buffered at all. If anything goes the slightest bit wrong, a voltage spike can and will fry the ever-loving electronic Jesus out of your video encoder. And as a matter of record, the only effect the component mod has on the AV port is that having both hooked up AT THE SAME TIME will cause the video from the AV port to dim by about 15% or so. Take note of the fact that the dimming only occurs when BOTH the component outs and the AV port are hooked up at the same time.
