Dear Experts After a good 7 hours trying various sync and framerate settings on my iScan HD+ "output settings" trying to match it at 1280x720x60Hz for my pj, I had succeeded getting a perfect pixel-match both horizontally and vertically, according to the two test patterns. What I cannot solve however is three pq problems: a random pixel "snow" noise (typically blue on black areas) AND/OR a "flicker" of any saturated coloured patterns AND/OR jumpy "judder" - this is not visible on the VLIN/HLIN screens but on anything else that has colour, such as the colour bar patterns. I tried playing with h-sync, porches and the frame rate, and I can never solve all those three problems. I can eliminate the "noise" by lowering fr to about 49.17Hz, but then I have a framerate "judder". If I get a lovely smooth moving bar on VJUD (at 60Hz), then the other two problems appear. If I minimise the "snow" then I get the "flicker" of coloured areas... And so on... The iScan is connected to the PE8700 (BenQ) via a 10m DVI-D lead. If anyone has suggestions (settings, kit, tests), I'd be grateful. If anyone is in or near Dublin and would like to get paid for a visit to solve it for me - let me know too. Oh: if I use lower resolutions I lose the pixel-perfection (on VLIN/HLIN and visibly when watching movies) but I have none of the snow/flicker/judder problems. Many many thanks, R.
