Is the NEC 4D not a true multi-sync monitor? The NEC 3D has no problem with normal NTSC signal, why does the 4D not have this capability. If it doesn't, you might be hard pressed getting the Lowell board to work with it (the preliminary info I've seen indicates that board outputs the same frequency signal as the standard Amiga - as does the Firecracker and the ColorBurst boards - the Harlequin has a non-interlaced mode).

The term "multi-sync" unfortunately has no well-defined meaning as far as what scan rates the monitor supports. All it means is that the monitor supports more than a single scan rate. The 3D supports ~15-36? khz, while the 4D supports something on the order of 25?-60?? khz (sorry, don't have the figures handy). So the 4D doesn't support NTSC (15 khz) rates (right?). From what I've heard about the A2410 Lowell board, it's horizontal freq. output is programmable, and can definitely go into the range supported by the NEC 4D. What I'd like to know is the exact range that can be generated by the board: can it go up to 60 khz for a 1000 line display? The A2410 sounds like a very exciting product. Unfortunately, it also sounds like a very expensive one (as far as hobbyists are concerned, anyhow; it'll probably be fairly cheap from the professional's point of view). A couple of questions for the net: I'm interested in the A2024 monitor. I've heard that in addition to its hires display of 1008x800, it can also act as a regular (grayscale) monitor for the other (standard) video modes. Is this true? And is this monitor available yet, or is a date set? What do users of it think about the refresh rate in hires? How does text scrolling look? Also, what 15-31 (or greater) multiscan monitors definitely support interlaced video well? I tried out a Packard-Bell (Samsung) monitor but it displayed the odd and even fields on top of each other with space between them. What experiences do others out there have? -Carl (mueller@cs.unc.edu)

The Sony CPD-1302 works with interlace. The old NEC Multisync II (JCP1401-P3A, or something like that) does not, it behaves exactly like the Packard-Bell you mention. I believe the NEC 3D does work with interlace, but I haven't seen it myself. -- Blaine Gardner @ Evans & Sutherland 580 Arapeen Drive, SLC, Utah 84108 blgardne@javelin.sim.es.com or ...dsd.es.com!javelin!blgardne DoD #0046 My other motorcycle is a Quadracer.

The old NEC Multisync II Correct. >(JCP1401-P3A, or something like that) does not, it behaves exactly like but not one field on top of aonther, like 2 halfs, it just has high distortion and flickering in the 15.75kHz interlaced mode since it's the lower bound of the range.

BIX: blaine_g > 305 miles to go.... Mitsubishi 1381A works also 15kHz interlaced. Check the manual for the horizontal sync/scan freq. if it goes down to 15kHz, and also check if it says it supports interlace. vertical freq. usually is compatible (50 - 60 Hz). However, I've still not found a monitor to buy which has perfect screen edge and corners, in the Amiga overscan signal. good luck, David

I extended as much as possible, and it just managed to fill the whole screen. Infact, it's perfect since when I open an overscan screen, it fills almost the whole screen. On WB screen, I don't see any black borders, only the blue background... :-) -TG

I'm using one now as I type, but in deinterlaced mode :-) There may be some difference between our two NECs, but mine does indeed display both fields on top of each other. Interlace is completely unusable on it.

I think I might have misunderstood. rather than what I thought: yours is top half bottom half : each looks same, one odd field, one even field. on top of each others" means (now I think) position of odd field and position of even field makes the lines overlapping rather than "interlacing" them. One thing agreed: it's unusable in 15kHz hor. David
