With the the MK III installed Im getting noise/distortion in high resolution modes. See attached picture. I do not have the noise issue at those resolutions without the card. (Standard Amiga output to SCART to HDMI converter)
I've clean the Lisa pins, reseated the card, tried different monitors and cables, with and without the ACA1233n accelerator, and with different power supplies.
One suggested solution was to jumper E127R.
