This is because it must bypass the de-interlacer (this may also be possible through the other connector if you throw the switch to disable the de-interlacer). NOTE: Why, with the de-interlacer do you even care about the productivity mode? It eats bus time so everything slows down, and it limits on screen colors to 2 or 4 of 64 vice 2, 4, 8, or 16 of 4096! As for the boarder problem, that is the fault of the monitor (not bad, almost all VGA and multi-syncs have the boarder). I have the 2000 and just got the Flicker-Fixer and was mad as hell about that boarder. One of the boons to owning an Amiga was that we could cover the entire screen with video. I didn't pay $1000 (monitor + FF) to look at a boarder! I had a DiamondScan at this point (less than a week old) and promptly returned it for a 1950 which allows me to get almost overscan (2-3 pixels on each side). When your (and I'll do this to mine too) monitor goes out of warranty (not use voiding it) you can take it to a computer or TV repair shop and have them adjust the horizontal so that you can have true overscan, if you want (I certainly do). This brings up a question: The Flicker-Fixer actually only displays about 719 of the 750-768 hi-res pixels generated by the Amiga starting from the left edge. What this amounts to is that the lost pixels are all at the right. Any standard disk (game etc.) with normal preferences, sits the normal 640 by 200 WB screen to the right edge of the display video. I CAN just adjust prefs to the left, but then when I display overscan HAM pix, I lose the first few pixels and have nasty rainbow fringing on the left side. Not to mention that my adjustments don't matter for self booting programs. I called the designer to see if there wasn't a way to split the loss of pixels between the left and right sides so the video that was there was at least centered (and maybe the GURU wouldn't sit over to the right either). He said that was rather difficult from an engineering standpoint, but said he was working on extending the pixels to the right side. What I'm curious about is whether the de-interlacer in your 3000 has similar limitations. In 1.3 does a GURU sit to the right edge of your grey video area? (of course the 1.3 in the 3000 is NOT the same as that I'm running and they could have moved the GURU to the new center so this may not be conclusive) Any observations you might have would be appreciated since my friend with the 3000 has been rather busy as of late. Hope I've helped. _______ __________ _/____) ' __ /_/ / ' / / __ _ "N.I.N.J.A.J.I.S."-Me / \___/__/___/ |_ /__/__/__/_/_-_/__/_/ The Displaced Razorback. ___________________________________________/ Founder: IDGAFF Ltd.
