I've tested a Taxan 795 on an A540. The monitor is not capable of
displaying the 'normal' screenmodes, modes 18, 19, 20, 21, 27, 28 and the
new super VGA mode 31 will work ok. In modes 18, 19, 20 and 21 the right
and left edges are not straight.
The 24/36 MHz VIDC clock on the A540 is switched automatically
to 36 MHz when needed (mode 31). If I knew a call to switch the clock
from 24 to 36 MHz when the display is in the not working modes, perhaps
the 795 will lock them succesfully.
One more strange feature of the 795 is a thin black horizontal
line about 2 inches from the bottom of the screen. Very annoying when you
are in the desktop and know the line is there. I was told this is common
with the sony trinitron tube.

This is unbelievable! Does this mean normal modes don't work with
multisynchs in general or is this taxan monitor a particularly
awkward case? I've just sent of for a Nec 3D & I'm going to be really
upset if it does this. Anyone used it on a 540?
[Need a new monitor coz my Acorn badged one has developed a terribke
judder - it's only a month old :-( ... going back this weekend]

I have an EIZO 9060S at home and it workes with ALL modes perfectly well and has a beautiful, sharp image. The Taxan monitor doesn't show the 'normal' modes beacuse in these modes the VIDC clock is changed back to 24Mhz. There are modules though, that leave the VIDC clock at 36Mhz also in the normal modes, so the Taxan ( or EIZO 9070 ) can synchronize. I don't know about the horizontal scan frequency range of the NEC 3D but if it doesn't synchronize at 15.xx kHz then you need a module that leaves the VIDC clock at 36MHz. (Your eyes will also be happy, becuase the frame rate goes up to 75Hz and the image doesn't flicker anymore). laci

Your NEC 3D should be able to show the other screen modes. In any case, if you call AcornBBS in Holland at +31 206631849 and download a file called SuperTool or something you'll find a complete description together with control software of how to build your own VIDCenhancer ala the one from Atomwide. And it'll cost you less than 10# ! Jens.

My Acorn badged monitor "blew up" just after the warranty ran o t, actually the line transformer blew, so I was told. Anyways, I bought a Taxan 775, and I'm very pleased with it myself, apart from it being a little dim on my A310. I heard that the 795 can't display normal modes (in BAU) , and since they made a point of saying that, I presume that this is a problem with just this monitor.

I don't know about the A540 with the 795 bui I recently bought a Taxan 775 for my A310 and discovered a thin black line appearing at the *top* of the screen. The way to cure this is to move the entire image down about 1/4" using the v.pos control and then resize the image with v.size. This produces an excellent picture, even if it is rather small. Andy.
