If you attempt to speed things up, as in by using 320x200 in some cases (as our smARTWORK product does for the most zoomed-in window on your printed-circuit board (4"x2.5")), you are out of luck.

The Sony Multiscan apparently supports all >the resolutions of the NEC Multisync Plus AND supports CGA resolutions also. Some boards, such as the Everex EVGA provide for this by double scanning. When the board is set up for "higher resolution" monitors, (the Sony is used as the example), 400 lines are displayed in 200 line modes. The 19" Multisync XL works very well in this mode, so I would expect the Plus would as well. On a separate note, our original Multiscan has been performing well in 800 by 600 mode, even though it's not rated for that resolution. Should I expect damage to result from this "misuse", or are the claims about these monitors not working in 800 by 600 mode based purely on the specs?

I have used two original NEC MultiSync, JC-1401P3A Monitors quite successfully in 800 by 600 "Enhanced" VGA mode. I would still welcome speculation as to whether this creates (internal) voltages or frequencies which may be harmful to the monitor's electronics.

This is, of course, speculation, but IBM wanted to come out with a new display for the PS/2 line that would make people buy True Blue for awhile. They came out with a monitor that had a scan rate somewhat beyond the spec limit for, say, the Multi-Sync. They were surprised when they discovered that the Multi-Sync was drastically under spec'ed due to some brilliant marketer at NEC that created the inaccurate specs in order to "not confuse the issue". The rest of this article is not speculation. NEC has officially stated that the standard Multi-Sync will run the high res modes of the VGA with no problem. The reason for the Multi-Sync plus (or II) is that IBM put in a wierd polarity change on the sync pulses to determine what resolution the monitor should be in. If you use a standard MS monitor, you may need to adjust the hold circuits when switching modes. If you use the MS-II monitor you may have sync problems on standard CGA. At least, this is what I have understood from what I have read. -- del (Erik Lindberg) uw-beaver!tikal!pilchuck!del

Pretty thin speculation. 640 X 480 (or multiples thereof) is a pretty standard resolution on many systems these days. -- Michael J.
